GHK-Cu (Copper Peptide)
A copper-binding tripeptide studied in the context of skin and tissue research.
Overview
GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-histidyl-lysine bound to copper). In research literature it is frequently studied for its interactions with skin, connective tissue, and remodeling pathways. It is one of the most commonly referenced copper peptides and appears in both topical and injectable research contexts.
Referenced research ranges
1–2 mg, once daily — topical research preparations reference lower concentrations applied to skin
Reconstitution default
50 mg in 5 mL yields 10 mg/mL; a 2 mg reference draw is 0.2 mL (20 units on a U-100 syringe).
Storage
Store lyophilized vials in a cool, dark place; refrigerate after reconstitution and protect from light.
Considerations
- Studied in both topical and injectable research contexts.
- The copper complex gives reconstituted solution a characteristic blue tint.
- Reconstituted peptide is temperature-sensitive and light-sensitive.
