Overview
About American Peptides
American Peptides is a research peptide supplier based in the United States. It started selling in 2026. We track 53 of its products across 29 compounds, and 48 are in stock right now.
We take every price straight from American Peptides' own product pages and convert it to cost per milligram. That way a single vial and a multi-vial kit can be compared fairly, and also compared with every other supplier we list. The prices on this page already include the 10% code.
47 of the 53 products link to a certificate of analysis (COA). You can open each one from the product listing. A COA covers one batch only, so always check that the lot number matches what you receive.
PepLookup does not sell these products. Every order is placed on American Peptides' own website, for laboratory research use only.

Where they are not the cheapest, the table shows how far off they are. Ranks use each supplier's listed price before any coupon code, and out-of-stock listings are left out before ranking. Every listing on this page shows the date we last saw its price.
