Scientific review: independent reviewer pendinghow our review works.

This is the Peptevity compound catalog — one evidence-graded monograph per peptide. Each page separates animal/in-vitro evidence from human evidence, grades every claim A–F, and states the compound’s dated FDA and legal status. We sell nothing and link to no vendor. For the live regulatory picture, see the 2026 regulatory tracker; for how the grades work, see our evidence-grading methodology.

How to read a monograph

Every compound page leads with a self-contained answer, carries a dated Regulatory status box, grades each claim by species and study type, and cites every efficacy or safety statement to a primary source. Where the marketing runs ahead of the evidence, we say so. See are peptides safe? for the cross-catalog safety view and animal vs human evidence for why preclinical results don’t transfer by default.

Every claim above is cited inline to a primary source. See how we grade evidence and our sourcing & citation policy.
