All peptides are guaranteed 99%+ pure. Each batch is independently tested by accredited U.S. laboratories using HPLC and Mass Spectrometry. A Certificate of Analysis is included with every order at no extra cost.

A COA is an official document from an independent laboratory that verifies the identity, purity, and potency of a peptide batch. Our COAs include HPLC purity analysis, mass spectrometry confirmation, sterility testing, and endotoxin results.

Allow the vial to reach room temperature. Use bacteriostatic water, injecting slowly down the inside wall of the vial. Gently swirl until fully dissolved — do not shake. Store reconstituted peptides at 2-8°C and use within 4-6 weeks.

Lyophilized (freeze-dried) peptides should be stored at -20°C for long-term storage or refrigerated at 2-8°C. Properly stored, they remain stable for 2+ years. Once reconstituted, refrigerate at 2-8°C and use within 4-6 weeks.

Our peptides are sourced from GMP-certified manufacturing facilities and independently tested in accredited U.S. laboratories. We maintain full chain-of-custody documentation from raw material sourcing through final packaging.
