Quality & Compliance
Every product is third-party tested before release. Purity is measured by HPLC, identity is confirmed by ESI-MS, and a Certificate of Analysis is included with every order. Analytical testing is performed at US-based laboratories.
Third-Party Tested
Testing is performed by outside analytical laboratories rather than self-reported, and the resulting data is documented on every COA.
HPLC Purity Analysis
Every lot is analyzed by reverse-phase HPLC. Purity is reported as % area, and chromatogram data is retained for each batch.
Mass Spectrometry ID
Identity is confirmed by ESI-MS for every product. Observed and theoretical molecular weights are reported on each COA.
Certificate of Analysis
Full COA included with every shipment, documenting identity, purity, lot number, test date, and storage conditions.
US-Based Testing
Analytical testing is performed at US-based laboratories, and the resulting data is what appears on your Certificate of Analysis.
Cold-Chain Shipping
Lyophilized peptides ship with insulated packaging and cold packs to maintain integrity throughout transit.
