Research-grade peptides. Third-party tested.

Our manifesto

About American Peptide Research

We built American Peptide Research because researchers deserve a supply chain they can verify—not vials with unverifiable purity claims and no batch documentation.

American Peptide Research supplies research-grade peptides with batch-level COA documentation, cold-chain shipping, and USA fulfillment. For laboratory research use only. Every compound in our catalog is lyophilized without fillers, tested by independent laboratories, and released with a certificate of analysis tied to a specific batch ID.

Our mission is simple: give laboratories the same quality bar they expect from pharmaceutical inputs—identity confirmation, purity profiling, and full traceability—applied to research peptides.

We are not a clinic. We do not provide medical advice. We supply research chemicals for qualified professionals conducting in vitro and laboratory work under appropriate institutional oversight.

US-made synthesis

Domestic production with documented supply chain from synthesis through lyophilization and release testing.

Third-party verification

Independent HPLC and LC-MS on every batch. Public certificates of analysis—not marketing claims.

Research-first standards

Products are sold strictly for in vitro and laboratory research. We support qualified researchers with traceable materials.

Transparent fulfillment

Batch-level documentation, insulated shipping, and responsive support when you need lot records for your lab.

Here's the COA. Verify it yourself.
