Coastal Peptides

Coastal Peptides publishes support@coastalpeptides.com and a mailing address at 3943 Irvine Boulevard #231 in Irvine, California. Its domain was registered January 12, 2024. The site states that fulfillment occurs in California, but it does not publicly name an owner or a clearly identified operating legal entity. PeptidePrices treats the Irvine suite as a mailing address, not proof of a laboratory or warehouse.

The public test-results page listed 22 product groups and 37 published Chromate records. Twenty-eight cards cover current products, including Epithalon 10mg, Glutathione 1500mg, MOTS-C 10mg, and GLP2-T 60mg marked in testing; nine additional cards cover previous batches. PeptidePrices inspected six direct certificates for NAD+ 500mg, BPC-157 10mg, CJC-1295 no DAC 10mg, GHK-Cu 100mg, KLOW 80mg, and CagriSema 10mg. All six resolved as direct Chromate records, which supports the COA verified label. That label verifies the certificates, not a universal pass: BPC-157 reported 97.931% purity against a displayed >98% specification, CJC-1295 reported 96.947% against the same threshold, CagriSema did not list purity, and the sampled set did not show sterility, endotoxin, or heavy-metals testing.
