About Peptide Library
Peptide Library is an independent platform for researching peptides, comparing vendors and pricing, calculating concentrations, and tracking research. It does not sell peptides. Content is for research and educational use only and is not medical advice.
What Peptide Library is
Peptide Library is a research, comparison, calculator, and tracking platform. On the web and in the iOS and Android apps, researchers can browse peptide profiles, compare independent vendor listings and price per mg, calculate reconstitution volumes, and keep personal logs.
The legal entity that operates the platform is Superfime LLC. Support is available at support@peptidelibrary.app.
What Peptide Library is not
- Not a peptide vendor. We do not sell, ship, or fulfill peptide products.
- Not a clinic, pharmacy, or medical service.
- Not medical advice, diagnosis, treatment, or prescribing guidance.
Where it is available
How we collect information
Vendor names, product listings, and prices come from publicly listed vendor catalogs that we compare for research planning. Price per mg is calculated when vial size in milligrams and list price are known. Rankings use reviewer scores — see How rankings work.
Some vendor links may include affiliate or coupon parameters. That does not change ranking placement. Vendors cannot pay to be ranked higher.
How peptide profiles are written and reviewed
Peptide profiles are compiled by the Peptide Library editorial team from peer-reviewed literature (PubMed and DOI-resolvable journals), public regulatory records (FDA, WADA) and chemical registries (PubChem, ChEMBL, DrugBank, FDA UNII). Cited PubMed studies are audited against the NCBI record, both that the citation is accurate and that the study is about the peptide it is cited for, and each profile carries its last review date. The methodology page describes the process and its limits; the editorial policy covers sourcing standards, what we will not publish, and how to report an error.
