Quality
How a lot is verified.
Independent testing, documented standards, and cold-chain logistics: the system behind "verified, not promised."
Reverse-phase HPLC
Each assayed lot is analysed by HPLC with UV detection coupled to mass spectrometry. The chromatogram and the percentage purity are recorded on that lot’s certificate — the trace shown is lot GS05-032026-1.
Mass-spec identity
Identity is confirmed by mass spectrometry to verify the compound matches its declared sequence and molecular weight.
Cleanroom handling
Lyophilisation, filling, and inspection happen under controlled-environment conditions to protect sterility and consistency.
Cold-chain dispatch
Finished vials are stored and dispatched cold, with handling designed to preserve potency from facility to bench.
