Advancing peptide science with uncompromising purity standards.
At Pristine Aminos, we exist to provide researchers and scientists with the highest-quality peptides available anywhere. Every compound we supply undergoes rigorous third-party testing to verify purity, identity, and integrity before it ever reaches your lab.
Founded by a team of biochemists and research scientists, we understand the difference that reagent quality makes to experimental outcomes. That's why we've built our entire operation around a single principle: no compromises on purity.
Every batch is verified by an independent third-party lab using HPLC purity analysis and mass spectrometry. No self-reporting, no exceptions.
All peptides are synthesized in our FDA-registered partner facilities in the United States under strict GMP-compliant conditions.
We publish Certificates of Analysis for every product lot on our Testing page. Your research deserves full data visibility.
Orders placed before 4PM Pacific ship the same day, Monday–Friday. Discreet packaging, cold-chain compliant.
Our team includes working scientists. We're here to answer compound questions, not just process transactions.
We regularly expand our catalog based on emerging research. If a compound is gaining traction in the literature, we're sourcing it.
