Audit Notes & Receipts

  • Publishes third-party COAs and has numerous user-submitted independent lab reports (Janoshik) 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.
  • (Note: an earlier record listed "ChemClarity" as a testing lab here, that is a chemistry-education resource, not an independent testing lab, and has been removed.).

Green bullets = directly verified data points. Amber bullets = caveats or open questions. Gray = disclosures.

Buyer Caution

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