Our Quality Standards
Every peptide we sell is held to the same rigorous quality benchmark — 99%+ purity, independently verified, before it ships.
Third-Party HPLC Testing
Every batch is tested by an independent US laboratory using High-Performance Liquid Chromatography. Results must confirm 99%+ purity before approved for sale.
Mass Spectrometry Confirmation
Mass spec analysis confirms the molecular weight of every peptide, verifying the correct compound is present and free from significant impurities or substitutions.
Certificate of Analysis (COA)
We publish a full batch-specific COA for every product. This includes the HPLC chromatogram, mass spec data, and purity percentage. Available on every product page.
USA-Sourced Synthesis
Our peptides are synthesized in the United States under strict GMP-aligned manufacturing conditions. We do not source from unverified overseas suppliers.
