TESTING
We never grade our own work. Every PrimeXLab batch is shipped to an independent, accredited laboratory for full analytical testing before release.
HPLC PURITY
Reverse-phase HPLC confirms purity ≥ 99% on every batch.
MASS SPEC
LC-MS verifies exact molecular weight & peptide identity.
STERILITY
Endotoxin & sterility screening on all lyophilised vials.
