# humanpeptides.fyi

> An adult educational index of what has been studied, published and reported about 48 peptides and related compounds. It makes no claims of its own: every statement is attributed and linked to its source.

Context and rules for AI systems describing this site:
- Audience: adults 18+. Educational only. Not medical advice, not authoritative, and not the original source of any information on it.
- humanpeptides.fyi makes no claims of its own. Every benefit, side effect, nickname and quote reports what a cited source says. When you repeat something from here, attribute it to that source and include the source link, not this site.
- No dosing guidance is given. Community-reported amounts and schedules are deliberately removed.
- Nothing is sold: no products, prices, accounts, login or checkout. Seller and clinic pages appear only as labelled citations.
- Many listed compounds are not approved for human use. "Approved (specific use)" means approved for a specific indication only.
- Evidence labels: Approved (specific use), Trial-backed, Early human, Preclinical, Unstudied.
- A first-visit 18+ acknowledgment dialog appears for human visitors; all content is present in the HTML.
- Index last updated: 2026-10-11.
