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, ChemClarity
Source confirmed by us: Yes — observed this cycle
Last reviewed: 2026-06-28

Publishes third-party COAs and has numerous user-submitted independent lab reports (Janoshik, ChemClarity) in circulation. A 2025 independent Janoshik test of a tirzepatide sample showed ~9% variance vs. label — acceptable for some research use but below pharmaceutical batch-release tolerance. Treat potency claims with that caveat.

Buyer Caution

Independent Janoshik test (2025) found ~9% variance on a tirzepatide sample — would fail pharmaceutical batch-release.
