Scientific review: independent reviewer pending — how our review works.
Peptevity is a vendor-neutral, evidence-graded reference for peptides in health, healing, and longevity. We do one thing: tell you what the research actually shows for each compound — what is human-tested, what is animal-only, and what its real FDA and legal status is — without selling anything. Most peptides discussed here are not FDA-approved and are sold “research use only.” This site is research and educational information, not medical advice.
Start here
- The 2026 Regulatory Tracker — the dated FDA / 503A / PCAC status of record for every peptide we cover.
- How we grade evidence — the A–F scale behind every claim, and why a strong rat study is still Grade C.
- Are peptides safe? — the evidence-graded safety reference.
Explore by silo
- Peptides explained — what peptides are, the major classes, and the research-vs-approved reality.
- Compound monographs — the catalog: one evidence-graded write-up per compound.
- Legality & FDA status — what “research use only” means, whether peptides are legal, and the dated tracker.
- Reconstitution & how-to — the laboratory procedures and the research-math calculator (never a human-dosing protocol).
The most-searched compounds
- BPC-157 and its nickname, the “wolverine peptide”
- GHK-Cu — the copper peptide
- Retatrutide — the investigational triple agonist, and its side effects
- TB-500, and BPC-157 vs TB-500
