Browse and research every peptide we track โ€” each graded with an evidence tier (Aโ€“D) and a safety light.

Showing 119 of 119
What do the evidence tiers (Aโ€“D) & safety lights mean?

AHuman-validated Backed by human clinical trials โ€” the strongest evidence we track.

BAnimal-grade Strong animal and mechanistic studies, with limited or early human data.

CAnecdotal Mostly real-world practitioner and user experience plus theory โ€” little formal study yet.

DInsufficient evidence Very little reliable data so far. Encyclopedia-only โ€” the builder never recommends these.
