A plain-language research database for the peptides people ask about most. Every compound is graded by how much human evidence exists, from randomized controlled trials down to cell-only studies, alongside its regulatory status. This is a reference for understanding the science, not a guide for using anything.
Read this first: Most compounds below are research chemicals that are not approved by the FDA for human use. A few are approved only as specific branded drugs (for example semaglutide as Wegovy or Ozempic). This tool describes evidence and status. It does not describe how to obtain, prepare, or use anything.
The strongest tier here. Randomized controlled trials in people have tested the compound, usually against a placebo. This is where confidence is highest, though an RCT existing does not by itself mean a compound is approved or appropriate for any individual.
Some human data exists, but it comes from small, early-phase, or narrowly focused studies. Results are preliminary and often not replicated at scale, so conclusions should be read with caution.
Evidence comes from animal models such as rodents. Effects seen in animals frequently fail to carry over to humans, so these findings describe biological potential rather than proven human benefit.
The weakest tier. Findings come only from cells, tissue, or other laboratory work with no whole-animal or human confirmation. This is the earliest stage of research and the furthest from any human conclusion.
This tool is educational and is not medical advice, diagnosis, or treatment, and it is not an endorsement of any compound. Many peptides listed here are research chemicals that are not approved for human use, and a few are approved only as specific branded drugs for specific conditions. Evidence tiers and study counts are simplified summaries of a moving research field and may not reflect the latest data. Nothing here explains how to obtain, prepare, dose, or administer any compound. Always consult a qualified, licensed healthcare provider before making any health decision.
