What is GHK-cu Pen?

Copper-binding tripeptide (GHK-Cu) studied in regeneration and skin research.

GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine complexed with copper) widely used as a reference compound in regenerative and skin research. It is studied in the context of collagen and extracellular-matrix synthesis, fibroblast activity and antioxidant signalling in cellular and preclinical models. Researchers investigate GHK-Cu for its role in tissue remodelling, wound-healing models and copper-dependent gene expression. Its distinctive copper-blue colour and well-characterised activity make it a benchmark in skin and longevity research. Third-party tested to 99%+ purity and supplied as a lyophilized powder for laboratory reconstitution. For research purposes only, not for human consumption.

How is GHK-cu Pen stored and handled?

Cold-chain storage

Store the pen at -20°C, protected from light. Once reconstituted or in use, refrigerate at 2-8°C and keep the cap on.

Reconstitution and priming

Use bacteriostatic water; add slowly down the inside wall of the pen cartridge. Swirl to dissolve, never shake, then attach a fresh 31G pen needle and prime before dialing a volume. See the in-house peptide calculator for dose volumes.

Pen needles

Pen needles are not included. Use a fresh standard 31G pen needle for every draw and remove it after use so the cartridge stays sealed.

For research use only

Not for human or veterinary consumption. Handle in accordance with your institution's laboratory safety protocols.
