All manuscripts must be submitted through our online peer review site:

**Please read all instructions below before proceeding**

All submitting authors are required to complete their submissions using an ORCID identifier. Please visit the ORCID website for more information, or to register.

**Create an Account in Manuscript Central

Submissions to Journal of Caffeine and Adenosine Research are managed through our online peer review system, Manuscript Central.  If you do not already have an account in Manuscript Central specifically for Journal of Caffeine and Adenosine Research, you will need to create one. Once your account is created, you may log in to the system to begin your submission. Each listed author on a submission must either already have an account, or have one created, in the system.  Before creating an account for your coauthor(s), search the database using your coauthors’ email address(es) to ascertain if an account already exists. If no account exists, you may create one on behalf of your coauthor(s).  For questions or technical assistance, contact



Manuscripts should be submitted with the understanding that they have neither been published, nor are under consideration for publication elsewhere, in the same or substantially similar form, except in the form of an abstract presented at a scientific conference.  


Use of English Language

 All submissions must be in English. Appropriate use of the English language is a requirement for review and publication in Journal of Caffeine and Adenosine Research. For authors whose native language is not English, we recommend using a service that will aid in the translation and rewriting of material into correct and proper English usage. The Publisher offers this service for a fee prior to official submission. For more information, please contact:  Please note that employing the use of the Publisher’s service, or any other service, is not required and using it does not guarantee acceptance of any paper.  



All submissions are subject to peer review.

Journal of Caffeine and Adenosine Research operates on a single-blind review process. All contributions will be initially evaluated by the Editor for suitability for the journal. During this preliminary assessment, the Editor may determine that the submission does not fall within the purview, aims, or scopes of the journal and may deny admittance to peer review.

All manuscripts deemed suitable and appropriate to the journal are sent to two (2) independent expert reviewers to assess the scientific quality of the paper.  During the submission process, the authors are provided the opportunity to name suggested/preferred reviewers and are asked to provide the names, contact information, and professional associations of five (5) well-qualified reviewers who are not from their university or institution, nor recent collaborators. Anyone the author prefers not to be considered to review his/her manuscript should be named as a non-preferred reviewer.  However, reviewer selection is ultimately at the discretion of the Editor.

Once all uploaded files are submitted, the system will generate an electronic proof in PDF format, which is used for peer review. All correspondence, including the Editor's decision and request for revisions, will be sent via email to the corresponding author of record.  The Editor is responsible for the final decision regarding acceptance or rejection of articles.  The Editor's decision is final and are not open to appeal, except in the case of the most extraordinary of circumstances.   


Time in Review

The journal strives to maintain a short, but thorough peer-review process. The average time in review is 35 days, but the Editor will endeavor to expedite manuscript handling if circumstances dictate. 



(Areas of Expertise to be used for peer review)

During submission, you will be asked to select 4-6 keywords from the drop-down list of pre-selected terms to facilitate the peer review process. These keywords will assist in the selection of skilled reviewers in the field for the purposes of peer review. 



Queries concerning the submission process, manuscript status, or journal procedures are to be directed to the Editorial Office.



Word limits do not include the title, abstract, authors and affiliations, keywords, figure legends, tables, acknowledgements, authorship confirmation statement, author disclosure statements, acknowledgments, footnotes, or references.  Exceptions to the limitations set herein are permissible at the discretion of the Editor(s).  Contact the Editorial Office prior to submission in such cases.

(Also see the section labeled “Detailed Information About Authorship” in the Journal Policies section below.)

Authorship should be determined at the time of submission. Ensure the author listing is complete and all names are spelled correctly at the time of submission.


Cover Letter

A cover letter is required and should be uploaded in Manuscript Central as a separate fileIt is strongly recommended that the cover letter specifically explain the importance and impact of the results of the submitted manuscript.  The cover letter should provide the postal address, telephone number and email address of the corresponding author. All editorial correspondence concerning receipt, status, review, revision, and publication of a manuscript will be directed to the corresponding author of record, who will be responsible for communicating the manuscript status to all co-authors of the paper and for obtaining the co-authors’ assent to any substantial changes of content or interpretation made during revision.  The cover letter must contain the following (or similar) language for the manuscript to be considered suitable for review:

“This original manuscript has never been published before and has not been, nor will be, submitted elsewhere while under consideration for publication by Journal of Caffeine and Adenosine Research.”



Manuscripts must be double-spaced, with each page sequentially numbered. Use of a template with numbered lines in the left margin is acceptable.  Preferred fonts are Times New Roman, Arial, and Symbol (for equations) in 12-point font size. (Other fonts may not translate properly and it behooves the submitting author to ensure that all special characters [e.g., Greek characters, mathematical symbols, etc.] are represented correctly in the body of the text and not as uninterpretable graphic representations at time of submission.)

File naming

  • Name all files in English and use only alphanumeric characters. Do not use symbols, dots, lines, or dashes

Title Page

Create an Effective Title:

Manuscript titles should be brief, contain key terms, and clearly identify the purpose of the work conducted

  • Effective titles are usually no more than 12-15 words
  • Titles should be direct and to the point.  Remember that the journal has a global readership, so clear and concise non-vernacular language is most effective
  • Avoid the use of specific locations in the title
  • Do not use proprietary/trademarked names in the title
  • Do not use acronyms in the title unless they are universally recognized and accepted
  • Whenever possible, avoid using the words, “The,” “An,” or “A” to begin the manuscript title.  (i.e.: “The Effects of Caffeine…” should be “Effects of Caffeine…”)
  • Avoid clichés, quotations, and figures of speech in titles.  Keep in mind that readers will search for specific keywords on the topic/area of study, not witty or entertaining phrases.  Pointed titles result in pointed discoverability.

A TITLE PAGE of your submission must be included as part of your main text document (not as a separate file) and must include the following items:

  • The complete title of the article;
  • All contributing authors’ full names, complete affiliation and mailing address, full contact information (telephone and e-mail address);
  • A brief running title of no more than 45 characters, including spaces;
  • Denotation of the corresponding author and his/her complete contact information including address and email address;
  • Three (3) to six (6) manuscript keywords.***

***Manuscript Keywords (search terms)

On the title page of the manuscript, include a minimum of three (3), maximum of six (6), search terms that will aid in the discoverability of the article in indexing services and search engines. These terms may or may not be different from the terms you selected for the peer review process and areas of expertise. You will be asked to retype these search terms in the submission form when uploading your manuscript. These keywords will be included in the published article. 


Authorship Confirmation Statement††

On a separate page within the manuscript file, following the title page, include a list detailing each listed authors’ contributions to and responsibilities for the manuscript. This text should also contain a statement by the corresponding author that all coauthors have reviewed and approved of the manuscript prior to submission. Lastly, include a confirmation statement that the manuscript has been submitted solely to this journal and is not published, in press, or submitted elsewhere (posting on a non-peer-reviewed preprint server does not constitute prior publication). 

†See the JOURNAL POLICIES section below or consult the International Committee of Medical Journal Editors ( for qualifications on authorship vs. contributorship.



At the end of the manuscript, after any acknowledgment statement(s) and before the reference section, include any financial conflicts of interest, actual or potential, for each listed author on the submission. If no conflicts exist, the authors must state, “No competing financial interests exist.” Articles submitted without Author Disclosure Statements will be un-submitted so that a statement may be added. If the submission is accepted for publication, all disclosure statements will be published in the article.

††See the JOURNAL POLICIES section below for more information, or consult the ICJME website at

Supplementary Information

When appropriate, we encourage the judicious use of online-only supplementary information (SI). All information/data in the SI should be referred to in the article text, including reference to specific tables and figures in the SI. Upload supplementary tables, figures, and legends as separate files, either as “supplementary file” or “supplementary file for review only.” The manuscript should be written so that the paper which appears in the printed journal contains all data which are key to the conclusions and important for the reader to have direct access to when reading the paper. Other supporting data and text are appropriate for the supplementary section.



Upload manuscript files to our system in the foll\0owing order:

  • Cover Letter
  • Manuscript/Main text file (including the Abstract, Authorship Confirmation Statement, Author Disclosure Statements, and References, as well as any Appendices, if applicable)
  • Tables

  • Figures
  • Supplementary files (if applicable)

Note:  There is a total limit of 200 MB per submission.




For Users of EndNote:  At this time, Journal of Caffeine and Adenosine Research does not yet have a template in EndNote, but you may use the journal Human Gene Therapy as a substitute as it follows the same reference style. Go to, search for “Human Gene Therapy,” and download the template.

[NOTE:  The publisher of Journal of Caffeine and Adenosine Research does not provide technical support for EndNote. If you have questions, click on the Support tab on EndNote’s website assistance.]


Reference List Preparation

Prepare a numbered (not alphabetical) reference list, in the order of citation within text and double spaced, at the end of the text of the manuscript (do not upload the reference list as a separate file).  See formatting examples below.

If more than three authors are listed on an article, list the first three authors then use et al. (not italic) after the third author’s name. Abbreviations of journal titles in the reference section should follow the style of MEDLINE.  If a work is in press, state the journal title in which it is to be published, and include "in press" in parenthesis in place of a volume and page range. When references to unpublished sources/correspondence are used, supply the researcher’s name and date.

In-Text Citations

Cite all references appearing in the reference list in numerical order, as superscripted numbers (no parentheses) and outside sentence punctuation.

If after peer review, you are invited to submit a revision, do NOT create a new submission. Detailed instructions for submitting revised manuscripts are provided in an email that is sent to the corresponding author containing the reviewers’ comments.  Revised submissions routinely will undergo further review by the same reviewers who assessed the original submission, members of the editorial board, and/or the editor(s).


Contact the Editorial Office immediately if the deadline for your revised submission has expired.  Do not create a new submission for a revision of an already-submitted paper.


Please note that an invitation to submit a revision does not guarantee acceptance. 



Upon acceptance of any manuscript, all authors will receive an email with detailed instructions and a unique, author-specific link to access and complete our online Copyright Agreement form. It is critical to ensure the accuracy of ALL authors’ email addresses when uploading submissions to Manuscript Central to ensure the proper delivery of all email communications. Failure of any author to submit their individual copyright from will result in a delay in publication. The corresponding author is responsible for communicating with coauthors to ensure they have completed the online copyright form. Authors not permitted to release copyright must still return the form acknowledging the statement of the reason for not releasing the copyright. Copyright forms may also be completed by logging in to the system using an author’s credentials. After logging on, click on Author Center and complete the forms located under “Manuscripts I Have Coauthored.”

Published manuscripts become the sole property of the Journal and will be copyrighted by Mary Ann Liebert, Inc., unless alternate arrangements are made prior to publication, including CC-BY licensing (see below). By submitting a manuscript to the Journal, the author(s) agree(s) to each of the above conditions. In addition, the author(s) explicitly assign(s) any copyrighted ownership he/she (they) may have in such manuscript to the Journal.



When reusing copyrighted material such as figures, tables, or any excerpted work, the author(s) must obtain permission from the original publisher and submit it concurrently with the manuscript. Written permission must be obtained from the copyright holder/publisher of the material concerned. The publication from which the material is taken must be listed in the reference list. Finally, a footnote to a reprinted table or the legend of a reprinted figure should read, “Reprinted with permission from Jones et al.” and list the corresponding superscripted reference number (i.e.: “Reprinted with permission from Jones et al.27”). All permissions must be supplied at the time of submission.  Authors are responsible for any fees that may be incurred by securing permission to reproduce or adapt material from other published sources.



All accepted manuscripts will go through copyediting, typesetting, figure sizing and placement, author proofing, corrections, revisions (from corrected proofs), online-ahead-of-print release, and lastly, issue assignment. Depending on the length and complexity of any accepted submission, these steps typically take 3-6 weeks from acceptance.



Page proofs will be sent to the (one) corresponding author as designated when the manuscript was submitted. It is the corresponding author’s responsibility to share the page proofs with co-authors and to coordinate all authors’ corrections into one proof. The Publisher will not accept corrections from multiple authors.



The corresponding author is responsible for returning corrections to page proofs, preferably within 72 hours of receipt. If the corresponding author does not respond within that time, the manuscript may be delayed in the publication schedule, or published as is, at the discretion of the Editor and Publisher. If the corresponding author expects to be unavailable during the time the manuscript is in production, the publisher should be provided with an alternate contact.

Only corrections directly related to errors in typesetting will be allowed. Other changes related to scientific content are generally not permitted at this stage and would require the approval of the Editor.



Reprints may be ordered by following the special instructions that will accompany the proofs, and should be ordered at the time the corresponding author returns the corrected page proofs to the Publisher as reprints ordered after the issue is printed will be charged at a substantially higher rate.






Journal of Caffeine and Adenosine Research follows the protocols and best practices for peer review set forth in the guidelines from the Committee on Publication Ethics (COPE) and the International Committee of Journal Medical Editors (ICJME). You may also refer to the American Medical Association (AMA) Manual of Style, 10e, for guidance on style requirements and standards.

Peer Review

Journal of Caffeine and Adenosine Research is a single-blinded peer-reviewed journal. All submissions are subject to peer review.



Editors and reviewers must maintain strict confidentiality of manuscripts during the peer-review process. Sharing a manuscript in whole or in part, outside the scope of what is necessary for assessment, is impermissible prior to the manuscript’s official publication date. 


Sharing of Materials Policy

Authors must honor any reasonable request for materials, methods, or data necessary to reproduce or validate the research findings during peer review, unless it violates the privacy or confidentiality of human research subjects.


Papers Authored by the Editor-in-Chief and/or Associate Editors

The Editor-in-Chief and Associate Editors will recuse themselves from participating in the review process of any manuscript in which there is a potential or actual competing interest.




Papers reporting human experimentation will be reviewed in accordance with the precepts established by the Declaration of Helsinki (2013).

Papers containing studies performed on human subjects must include a statement that the investigations were performed after approval by a local Human Investigations Committee or Institutional Review Board, and after obtaining informed consent from a patient (or other responsible individuals).  Copies of such documentation must be submitted to the journal upon submission in order for the paper to go through proper peer review. It is required that the author(s) retain and archive all relevant forms, releases, statements, and consents.

Patient anonymity is paramount and must be protected as required by law. In most cases, a general description of the patient(s) is sufficient insofar as meaning is not lost.  Nonessential data (age, sex, occupation, etc.) should not be included in a manuscript unless it is clinically or epidemiologically relevant or important to the manuscript.


When reporting research involving human data, authors should indicate whether the procedures followed have been assessed by the responsible review committee (institutional and national), or if no formal ethics committee is available, were in accordance with the Declaration of Helsinki as revised in 2013. If doubt exists whether the research was conducted in accordance with the Helsinki Declaration, the authors must explain the rationale for their approach and demonstrate that the institutional review body explicitly approved the doubtful aspects of the study. Approval by a responsible review committee does not preclude editors from forming their own judgment whether the conduct of the research was appropriate.

A sentence declaring adherence to Institutional Review Board protocols should be included in the Materials and Methods section of the manuscript.  If the study is judged exempt from approval from an Institutional Review Board, a statement from the committee is required indicating a waiver has been issued. Informed consent by participants should always be secured. If securing consent is not possible, an institutional review board must decide if it is ethically acceptable to submit the work to the journal for peer review and possible publication. This information should be outlined in the cover letter accompanying the submission.

Patient consent includes an opportunity for the patient(s) to read the manuscript prior to submission or waive the right to do so.

The patient confidentiality and consent requirements contained herein are applicable to any text, photograph, image, video, or any other media submitted to Journal of Caffeine and Adenosine Research. 



Authors must clearly state in the text that the experiments were carried out in compliance with the relevant local institutional reviewed animal use regulations and/or national laws relating to the conduct of animal experimentation, or, where such laws do not exist, that the studies were performed in accordance with an internationally recognized code of practice.  Authors should clearly state source(s) and numbers of animals being used in all experiments in their manuscript.



All authors are encouraged to complete their submissions using an ORCID identifier. Please visit the ORCID website for more information, or to register.

Authorship Limit

There is a limit of 35 authors permitted on a single submission, but in cases where there are 20 or more co-authors, Journal of Caffeine and Adenosine Research recommends that a collective group or consortium name is provided and the individual authors and their affiliations listed in the Acknowledgements.

Authorship should be determined at the time of submission. Ensure the author listing is complete and all names are spelled correctly.  As determined by the International Committee of Medical Journal Editors (ICJME), authorship is defined*** using the following criteria:


  1. Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; AND
  2. Drafting the work or revising it critically for important intellectual content; AND
  3. Final approval of the version to be published; AND
  4. Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.


***Consult the International Committee of Medical Journal Editors for differing qualifications for authors vs. contributors.

Corresponding Author

Note:  The submission system only permits one author to be classified as the corresponding author. This designation should be determined at the time of submission. The named individual will be responsible for receiving all communications regarding the submission and will be directed only to the corresponding author.  The corresponding author designated in Manuscript Central will be responsible for communicating to all other coauthors.  The journal editorial office or the publisher will only provide information to the designated corresponding author.  (The only exception is with regard to copyright forms. If a submission is accepted, each author will receive a unique link to their individualized copyright form sent to them via email).

If a submission requires two corresponding authors to be listed, it should be noted on the title page of the manuscript.  It is preferred to list no more than two corresponding authors.

Acknowledgment of Non-Qualifying Contributors

Contributors who do not meet all for of the criteria for authorship as defined by the ICMJE should not be listed as authors, but they should be recognized in the Acknowledgments section.  Some (not all) examples of activities that alone (without other contributions) do not qualify a contributor for authorship are:

  • acquisition of funding or provision materials;
  • general supervision of a research group or general administrative support
  • writing assistance, technical editing, language editing, and proofreading

 Those whose contributions do not justify authorship may be acknowledged individually or together as a group under the single heading, Acknowledgments.

Submitting Author/Agent:

It is incumbent upon the submitting author/agent to ensure the inclusion and accuracy of all contributing authors’ names and affiliations upon original submission of the paper. Once a paper is accepted for publication, changes in authorship – including the page proof stage – are generally not permitted.  (See the Changes in Authorship section below.) 

Variations of Authorship

It is permissible to list two authors as co-first authors or as equal contributors.  Include an asterisk (*) next to the authors’ names who are considered as first authors.  Include a corresponding footnote, using the asterisk, on the title page that reads, “These authors contributed equally to this work and are considered to be co-first authors.” 

Working Groups or Teams

May be listed in the manuscript byline, but the entire listing of names and their affiliations should be included in the acknowledgment section of the manuscript.  Do not list the names in a footnote on the title page.  Following this method ensures that all participants of Working Groups or Teams will appear correctly in Medline and other indexing databases.

Changes in Authorship 

Changes in authorship after acceptance are generally discouraged, but the editorial leadership recognizes that in certain circumstances, it is required. The journal’s policy is as follows:

  1. A request to alter authorship must be made in writing from the corresponding author to the Editor-in-Chief, with a detailed explanation for the request, and the names and affiliations of the authors requiring addition and/or deletion.
  2. Authorship may be altered after acceptance of a paper with the written approval of all authors named on the manuscript, as well as the individual(s) being added and/or deleted. The Publisher can provide a form for this, if needed.
  3. Upon receipt of the request and all written approvals of all involved parties, the Editor-in-Chief will consider the request, render a decision, and notify the corresponding author.
  4. There is a one-year post-publication statute of limitation on requests for alterations in authorship.


***Important Note about Author Listing***


It is incumbent upon the submitting author to ensure the accuracy and inclusion of all contributing authors’ names and affiliations upon original submission of the paper. All authors’ names must be entered into the Journal’s submission site.


  1. Competing Interests. A competing interest exists when an individual (or the individual’s institution) has financial or personal relationships that may inappropriately influence his actions. These competing interests may be potential or actual, financial or other.
  2. Personal Financial Interests. Stocks or shares in a company that may gain or lose financially from publication of the article; consulting fees or other remuneration from an organization that may gain or lose financially from publication of the article; patents or patent applications that are owned by or licensed to companies/institutions that may gain or lose value from publication of the article.

  5. Material failure to comply with legislative and regulatory requirements affecting research:
    Including but not limited to serious or substantial, repeated, willful violations of applicable local regulations and law involving the use of funds, care of animals, human subjects, investigational drugs, recombinant products, new devices, or radioactive, biologic, or chemical materials constitutes misconduct.
  6. Conflict of Interest:  Nondisclosure of any conflicts, direct or indirect, to the Journal which prevents you from being unbiased constitutes misconduct.
  7. Deliberate misrepresentation: of qualifications, experience, or research accomplishments to advance the research program, to obtain external funding, or for other professional advancement constitutes misconduct and/or fraud.
  8. Plagiarism: Purposely claiming another’s work or idea as your own constitutes misconduct and/or fraud.
  9. Simultaneous Submission:  Submitting a paper to more than one publication at the same time constitutes misconduct.



Scientific misconduct includes but is not limited to data fabrication; data falsification including deceptive manipulation of data and images; and plagiarism.  While each of these practices is problematic, they are not equivalent. If an instance of suspected misconduct in submitted or published work is presented to the editorial leadership and/or publisher of Journal of Caffeine and Adenosine Research, the journal will follow the protocols set forth by the Committee of Publication Ethics.   Pending the results of this procedure, the editor(s) may choose to publish an Expression of Concern.  If such procedures involve an investigation with/by the authors’ institution(s), the editors will seek to discover the results of that investigation and notify the readership of the journal of said findings.  If the investigation(s) prove(s) scientific misconduct, the journal will publish an official retraction of the article(s).   There may be circumstances in which no misconduct is proven, but an exchange of letters to the editor may be published to highlight matters of debate to the journal’s readership.




The Publisher is committed to helping protect the integrity of the public scientific record by sharing reasonable concerns with authorities who are in the position to conduct an appropriate investigation into an allegation.  As such, all allegations of misconduct will be referred to the Editor-In-Chief of the Journal who in turn will review the circumstances, possibly in consultation with associate editors and/or members of the editorial board. Initial fact-finding will usually include a request to all the involved parties to state their case and explain the circumstances in writing. In questions of research misconduct centering on methods or technical issues, the Editor-In-Chief may confidentially consult experts who are blinded to the identity of the individuals, or if the allegation is against an editor, an outside expert. The Editor-In-Chief will arrive at a conclusion as to whether there is enough reasonable evidence that the possibility of misconduct occurred.

When allegations concern authors, the peer review and publication process for the manuscript in question will cease while the process described herein is researched. The investigation will be taken to completion even if the authors withdraw their paper.  In the case of allegations against reviewers or editors, they will be replaced in the review process while the matter is investigated.

Editors or reviewers who are found to have engaged in scientific misconduct will be removed from further association with the Journal, and reported to their institution.

If an inquiry concludes there is a reasonable possibility of misconduct, the Editor-in-Chief will retract the paper from the Journal and the scientific record.  If the paper is still under peer review, the Editor-in-Chief will withdraw the paper from consideration to the Journal.

All allegations will be kept confidential.
