QUALITY STANDARD

Where science meets
precision.

Prime Peptides is engineered for laboratories that cannot afford to guess. Every compound moves through a six-stage QA pipeline before it leaves our facility.

HPLC ≥ 99% Purity

High-performance liquid chromatography on every batch, twice — once in-house, once by an independent lab.

Mass Spectrometry

Molecular weight and sequence confirmed against reference standards for every production lot.

Endotoxin & Sterility

LAL testing and USP <71> sterility protocols performed before any release to shipment.

GMP Manufacturing

All peptides synthesised in a GMP-audited facility with full batch traceability.

Cold-Chain Handling

Lyophilised compounds stored below -20°C and shipped in temperature-controlled packaging.

Certificate of Analysis

A signed COA is issued for every lot number and available to download with every order.
