peptides.fyi is an independent educational reference covering peptides, GLPs, SARMs, research chemicals (including SERMs), and cofactors. Because this is health-adjacent information that people may use to inform real decisions, we hold our content to a documented standard. This page explains how that content is produced: the sources we use, how we review for accuracy, how we handle updates and corrections, and how we keep our editorial work independent of the affiliate links that support the site.
How we research
Every compound profile and article is built from primary and authoritative sources rather than secondary blog content or vendor marketing. In practice that means we work from:
- Peer-reviewed literature indexed in PubMed (U.S. National Library of Medicine), citing specific studies, journals, and years where claims are made.
- Registered clinical trials via ClinicalTrials.gov, to distinguish what has actually been tested in humans from what has only been studied in animals or cell models.
- Chemical and structural data from PubChem for molecular formulas, weights, and structures.
- Regulatory records from agencies such as the FDA and EMA for approval status, safety communications, and scheduling.
Profiles describe the studies, trials, and regulatory decisions they rely on, with dates, so readers can look them up in these databases and check our summaries against the sources themselves.
How we write
- Evidence first. We report what the published research shows, and we say so plainly when evidence is preclinical, limited, or absent. We do not present animal-model findings as if they were established human outcomes.
- No medical advice or health claims. Our content is educational. We describe mechanisms and research findings; we do not recommend, prescribe, or instruct anyone to use any compound.
- Research-use framing. Many compounds we cover are not approved for human use. We label regulatory status clearly and treat these compounds as research materials, not therapeutics.
- Plain language. We aim to make complex pharmacology understandable without sacrificing accuracy.
Review and accuracy
Before a compound profile is published, it is reviewed for scientific accuracy against the sources it relies on, checking that mechanisms, molecular data, regulatory status, and study descriptions match the underlying literature. Profiles carry a visible "last updated" date so readers can judge how current the information is. Where the evidence base is thin or contested, we state that directly rather than papering over the uncertainty.
Updates and corrections
Research evolves, and so do these pages. We revisit profiles as new studies, trial results, or regulatory decisions are published, and we update the content and its "last updated" date accordingly. If you spot an error or an out-of-date claim, we want to fix it: email [email protected] with the page and the correction, and we will review it against the sources and amend the page where warranted.
Authorship
Content on peptides.fyi is produced by our editorial team: writers and researchers who compile and fact-check each profile against published literature. Each article carries a byline and a "last updated" date. Our contributors are science writers and researchers, not medical professionals; the site reports what the published research says rather than offering personal clinical opinion or claims.
Our editorial contributors include:
- Jill Carol
- Nelson Carrillo
- Jaimie Grant
- Joseph Moore
- Benny Laituri
- Casey Maben
Each contributor's focus is described on the editorial team page.
Independence and how we are funded
peptides.fyi does not sell, manufacture, or ship any products. The site is reader-supported. It participates in the affiliate programs of Peptide Club and Peptides Warehouse and may earn a commission when readers purchase through links to those vendors. These relationships never influence which compounds we cover, what the research says, or the conclusions we draw. Affiliate links are labeled, and our full Affiliate Disclosure explains the arrangement in detail. Editorial decisions are made independently of commercial relationships.
Medical disclaimer
The information on peptides.fyi is provided for educational and research purposes only. It is not medical advice and is not a substitute for professional medical guidance, diagnosis, or treatment. Many compounds discussed are research materials not approved by the FDA or other regulators for human use. Always consult a qualified healthcare professional before making any decision related to your health, and never disregard or delay professional medical advice because of something you have read here.
