GHK
Lyophilized reference material, 50mg vial.
What it is
GHK is supplied as a lyophilized powder in a sealed 50mg vial, assayed at 99.2% by HPLC with identity confirmed by mass spectrometry. Every lot ships against its own Certificate of Analysis, which is published on this page before you order rather than sent afterwards. Supplied strictly as laboratory reference material. For research use only — not for human or veterinary use.
What the testing shows
HPLC establishes the purity figure on the certificate: the proportion of total peak area attributable to the target material. Mass spectrometry is the separate question of identity. Both are run per lot by an independent laboratory, and the certificate for the lot you receive is published before you order.

Storage
Keep the vial sealed, cold and out of direct light. Lyophilized material is considerably more stable dry than in solution.
Questions
What purity does this lot carry?
99.2% by HPLC on the current lot. The figure on the Certificate of Analysis is the one that ships with your vial.
What does mass spectrometry add over HPLC?
HPLC gives the purity figure — how much of the sample is the target. Mass spectrometry is the separate question of identity, confirming the observed mass matches what was ordered, so a pure sample of the wrong material cannot pass as a clean one.
How should it be stored?
Sealed, cold and out of light. Lyophilized material is considerably more stable dry than in solution.
