Certificates of Analysis

Every lot is sampled and sent to an independent analytical laboratory before it enters inventory. Match the lot number printed on your vial to the row below to pull the full HPLC chromatogram and mass-spec report.

Compound Strength Lot number Tested Purity (HPLC) Identity (MS) Report

Reverse-phase HPLC

Purity assay run against a reference standard. Any lot returning under 98% is rejected outright and never listed.

Mass spectrometry

Confirms the observed molecular weight matches the theoretical mass for the sequence, ruling out substitution.

Sterility & endotoxin

Finished vials are screened for microbial contamination and bacterial endotoxin before release.
