Retapedia is a free, web-based reference resource that compiles summarised information about peptide compounds — their reported effects, regulatory status, and classification under tested natural-bodybuilding rulebooks. Articles are written in an encyclopedic register and cite primary research, regulatory documents, and federation rulebooks where available.
Mission
Retapedia exists to make the published evidence on peptide compounds legible to a general reader — particularly readers competing under drug-tested rulebooks who need a clear answer to the question of whether a given compound is permitted in their sport. Each article aims to summarise the relevant literature accurately, link to primary sources, and state plainly whether the compound is natty or not natty under the prevailing tested standards.
Scope
The encyclopedia covers research peptides, peptide hormones, growth-factor analogues, and related small-molecule compounds that have entered mainstream discussion in fitness and longevity communities. Each entry typically documents:
- mechanism of action and reported effects;
- regulatory status with the FDA and equivalent bodies;
- status under the WADA prohibited list and major natural-bodybuilding federations;
- citations to primary research and clinical trials, where they exist.
Editorial approach
Articles are compiled from peer-reviewed research, regulatory filings, federation rulebooks, and publicly available data. Where the evidence is thin or contested, Retapedia says so. The site does not promote, sell, or recommend any compound; affiliate links, where present, fund the encyclopedia's hosting and content development.
Not medical advice
Many of the peptides catalogued here are not approved for human therapeutic use and are sold for laboratory-research purposes only. Readers are responsible for compliance with the laws of their jurisdiction.
