We third-party test our peptides through an independent laboratory. Where a lot is tested, the full report is available with the vial. We're expanding testing across the catalog, starting with our best-sellers.
Compounds are produced using solid-phase peptide synthesis, then lyophilized for stability.
Lots are sampled and sent to Janoshik Analytical for reverse-phase HPLC purity analysis at 220 nm.
Mass spectrometry confirms identity; net peptide content and water content are quantified against reference standards.
Endotoxin levels are measured by LAL assay on tested lots. Lots exceeding thresholds are rejected.
Tested lots that pass each check are assigned a batch number, matched to their CoA, and released to inventory.
Tested lots link their batch CoA on the product page. Browse the catalog to see one.
One account for orders, batch CoAs, and reorders. Two minutes to set up.
