The 50 mg GHK-Cu loading reflects the higher concentrations used in dermal fibroblast and ECM gene-expression assays where the copper tripeptide is typically the primary readout
Using 5-chloromethylfluorescein diacetate (CMFDA), which has been reported to be a potent and irreversible GSTO1 inhibitor 22 , we optimized a gel-based binding assay that measures competitive inhibition of CMFDA binding to recombinant GSTO1 or endogenous GSTO1 in a soluble proteome (Supplementary Fig
FDA and Regulatory Status of GHK-Cu Peptide GHK-Cu regulatory status depends on whether it is discussed as a cosmetic ingredient, a compounded bulk drug substance, an injectable preparation, or an investigational product
It is backed by ISO 17025-accredited third-party testing and NSF-certified manufacturing, while product-specific testing is not currently verified by SuppCo
