Wholesale GHK-Cu (Copper Tripeptide-1)
The most in-demand copper peptide in professional skincare formulation, manufactured to GMP standard at ≥98% HPLC purity with a batch COA included. Supplied wholesale and white label to skincare brands, cosmetic manufacturers and formulation laboratories across Europe and internationally.
Overview
The benchmark copper peptide
GHK-Cu is a naturally occurring tripeptide — glycyl-L-histidyl-L-lysine — complexed with copper(II). It was identified by Loren Pickart in 1973, isolated from human plasma, and has since become one of the most extensively documented peptides in cosmetic science. Levels in plasma decline with age, which is the basis of its positioning in anti-ageing formulation.
It is used in skincare formulation for skin-conditioning and appearance-smoothing applications, and is frequently positioned as a premium hero ingredient because of its strong name recognition among consumers.
SARMs-Direct supplies wholesale GHK-Cu to skincare brands, cosmetic manufacturers, ingredient distributors, formulation laboratories and private label buyers across Europe and internationally. All supply is GMP-certified with full batch documentation and a COA included.
Consumer recognition
"Copper peptide" is one of the few ingredient names consumers actively search for.

For your formulators
Formulation considerations
GHK-Cu behaves differently from most cosmetic peptides. These are the practical points our formulation customers ask about most — worth reviewing before you specify it into a product.
Working with GHK-Cu
- ● It is blue, and it will colour your formula. The copper complex carries a deep blue tint that shows through at typical use levels. Many brands treat this as a visual signature; if you need a colourless base, factor it in early.
- ● pH matters. The copper complex is pH-sensitive. Formulating outside a suitable range can destabilise it.
- ● Watch combinations with strong acids. High-dose ascorbic acid and low-pH acid systems can compete for the copper and disrupt the complex. Brands commonly separate these into different products or different steps in a routine.
- ● Water soluble. Suits aqueous serums, essences and lightweight emulsions.
- ● Protect from light and heat. Store cool and dry; refrigerate for long-term storage of raw material.
General formulation guidance only. Use levels, stability and compatibility should be validated in your own formulation and stability testing.
