COAs

Certificates of Analysis (COAs)

Transparent quality you can verify. Our third‑party testing results will appear here as they’re finalized.

Current status: We’ve completed initial vendor COA review and are awaiting our own independent third‑party test reports. If you have an order pending and would like to review a COA before purchase, contact us and we’ll share the most current available documentation.

How we handle COAs

  • Each batch is tested by an ISO/IEC 17025–accredited third‑party laboratory where applicable.
  • Reports include identity, purity, potency, and contaminant screening when relevant to the product.
  • We cross‑check vendor documentation while our own reports are pending; once available, our independent COAs replace vendor‑only files on this page.
