Frequently asked questions
What is PeptideComps?
An independent comparison site for research peptides. We collect prices from 76 vendors' public product listings, convert every listing to a price per milligram, and show what is publicly known about each vendor's testing. We don't sell anything.
How are prices compared?
Vendors sell different vial sizes, multi-vial kits and capsule bottles, so sticker prices aren't comparable. We read the size from each listing, calculate the price per mg, and compare vials of the same size against each other. Kits and listings that look like errors are kept out of headline prices.
Do you test products or verify vendors?
No. We don't test anything. “COA claimed” means the vendor says it publishes certificates of analysis. Where independent lab results exist (from Finnrick), we show that rating separately, and notes about vendors come from public sources and are often unverified.
Are these products for human use?
No. The products listed are sold for laboratory research use only. They are not approved drugs or supplements, and nothing on this site is medical advice.
