COA & Third-Party Testing

Transparency is the product.

At GlowStrong, purity is never a claim — it is a documented result. Every batch we release is independently analyzed by accredited third-party laboratories before it reaches your bench, and the findings are yours to review.

What we test for

  • Purity by HPLC — High-performance liquid chromatography quantifies the percentage of target compound in each lot. Our standard is 99% or higher.
  • Identity by Mass Spectrometry — MS confirms the molecular weight and identity of the peptide, verifying you receive exactly what is on the label.
  • Endotoxin and sterility screening — Additional screening supports the integrity of research-grade material.

Verify your batch

Every GlowStrong product ships with a batch number printed on the vial. Enter that batch number in the verification field to retrieve the exact certificate of analysis for your lot. No generic samples — full, lot-specific traceability.

Why it matters

Research is only as reliable as the inputs behind it. By publishing our analytical data, we give you a foundation you can document, cite, and defend. If a result ever falls short of our standard, the lot does not ship.

All products are for laboratory research use only.
