COA status: Publishes COAs — audit pending

Certificate of Analysis (COA)

The vendor publishes COAs, but PepEvolution has not yet independently authenticated or batch-matched them.

Testing lab(s): Janoshik, Peptide Test
Source confirmed by us: Yes — observed this cycle
Last reviewed: 2026-06-28

Independent third-party testing via Janoshik and Peptide Test, with sampled batches reported at ~97.8–99.3% purity. Caveat: third-party verification is published selectively (some compounds/lots), not for every batch shipped. Confirm a current COA for your specific lot.
