Our Verdict
Penguin Peptides sends samples to Janoshik, a well-known independent testing lab, for third-party purity verification. Of the 18 products tested, 17 came back above 95% purity. The exception is BPC-157, which tested at 91.6% — below the 95% quality floor and a meaningful flag for their flagship peptide. Everything else is clean: Ipamorelin at 99.85%, MOTS-C at 99.84%, PT-141 at 99.84%. Physical address is on file. No ownership disclosure, no pricing data in our database, no batch numbers on COAs. The BPC-157 result alone prevents a Trusted-tier rating — it's not acceptable at that price point from a vendor using independent testing.
