How Peptidology tests every batch

Every lot we ship goes through independent third-party laboratory testing at ISO-17025 accredited facilities. We classify each batch into one of two tiers based on how comprehensively it was tested:

7× Standard release battery

Purity · Quantity · Identity · Endotoxins · Heavy Metals · Sterility from two labs. The minimum every batch we sell must pass.

14× Advanced testing

The 7× battery PLUS: TFA residual · Industrial solvents · Conformity · Solubility · Container Closure Integrity. Our most thoroughly characterized lots.

Heavy metals limits are computed dose-dependently per USP <232> parenteral PDEs. Endotoxin pass/fail is referenced against the USP/FDA 5 EU/kg threshold (350 EU for a 70 kg adult).
