Peptide Library

Peptide Library gives Claude structured access to Peptide Library's database of more than 200 reviewed peptide research profiles.

Ask about a peptide by name, synonym or research code to get its classification, proposed mechanism and targets, research areas, safety notes and regulatory status (FDA, WADA). Evidence is reported by study type: regulatory labels, controlled human trials, other human studies, and animal or laboratory research, each with its cited sources, so animal findings are never presented as human results. Fields a profile does not document are reported as not documented rather than filled in.

You can also compare two or three peptides side by side without ranking them, browse the seven research categories, search Peptide Library's FAQs, articles and free courses, see this week's most-researched peptides as percentages, and do unit arithmetic: mg, mcg and IU conversion (IU only with a factor the profile documents), solution and blend concentrations, and cost per mg from prices you provide. Every result links to its source page on peptidelibrary.app.

Read-only and anonymous: no account and no personal data. For research and education only, not medical advice: it never returns doses, dosing schedules, cycles, or injection or reconstitution instructions, and it lists no vendors, prices or places to buy.
