At Proxiva Peptides, transparency is the foundation of everything we do. Every batch of peptides we offer undergoes rigorous third-party laboratory testing to verify purity, identity, and composition.

Below you will find our most recent Certificates of Analysis (COAs) — independent lab reports that confirm each product meets our strict quality standards before it ever reaches your hands.

Since 2021, Proxiva Peptides has been a trusted name in the research peptide industry. We take immense pride in supplying only USA-manufactured peptides held to the highest standards of purity and potency — because the quality of your research starts with the quality of your materials.

All certificates of analysis are conducted by independent, accredited laboratories. Proxiva Peptides has no affiliation with any testing facility — ensuring complete objectivity and unbiased results for every product we offer.
