Figure 2: Quality Metrics
GHK-Cu raw powder is supplied for incorporation into custom topical formulations, serums, and cream bases. Because copper peptide is inherently water-soluble, it integrates readily into aqueous phases without the need for co-solvents. Formulators typically target final concentrations between 0.5–2% w/v, although higher concentrations have been employed in concentrated ampoule preparations.
Bulk GHK-Cu powder should be stored desiccated at −20°C for long-term stability or 2–8°C for working stock. The lyophilized form is stable for 24+ months under these conditions. Avoid repeated freeze-thaw cycles once reconstituted. Copper peptides are light-sensitive; amber glass or opaque containers are recommended for storage of both raw powder and finished formulations.

absolute unit of a product lmao. but fr tho the quality is insane. dissolved perfectly, stable in solution, and our assay results are extremely consistent
good experience overall. ordered twice now. first order was perfect, second one had a slight delay in shipping but they were responsive about it. product quality is consistent
thx for the great service and fast delivery. had a question about storage and support got back to me same day. product is excellent as always
Ran our own HPLC analysis and got 99.4%. Matches the published COA closely.
