Quality & testing
Nothing ships without its analytical record.
Purity claims are easy to print. We would rather show the process behind them: who tests the material, what is measured, and what happens when a lot fails.
Synthesis and sourcing
Compounds are produced by solid-phase peptide synthesis at cGMP-audited facilities. We record the manufacturing site and synthesis date for every lot we accept.
Independent assay
Before a lot is listed, a sample is sent to an outside analytical laboratory for HPLC purity and mass spectrometry identity confirmation. We do not test our own material.
Endotoxin and sterility screening
Lots are screened for bacterial endotoxin and visual particulates. Anything that falls outside specification is rejected rather than discounted.
Sealing and cold storage
Accepted material is lyophilized, sealed under inert gas with a crimped stopper, and held at controlled temperature until it is packed for dispatch.
Batch documentation
Every vial is traceable to a batch number printed on the label and to the analytical document behind it. Request the COA for any lot, before or after purchase.
