How to read these numbers

The purity is the number the lab measured, not a floor. 99.92% means 99.92%, never “at least 99”. It comes from reversed-phase HPLC; identity is confirmed separately by mass spectrometry.

We don’t test our own product. Every lot goes to an independent, named lab — this one to Freedom Diagnostics. The certificate is published here before the buy button works, and the lot number on your vial is the one on the report.

If a batch misses its spec, it never ships. And if a vial you hold doesn’t match its report, test it at any lab you like and we refund every dollar. Holding a vial now? Look up its lot number in the registry.

What the published studies report about Tesamorelin — cited, numbered, and hedged to the evidence — is in Tesamorelin vs Sermorelin vs Ipamorelin: What the Evidence Shows.

The full walkthrough — matching the lot, reading the HPLC figure, confirming identity by mass spectrometry — is in How to Read a Peptide COA (and Spot a Bad One).
