About GHK-Cu

GHK-Cu (Glycyl-L-Histidyl-L-Lysine copper complex) is a naturally occurring tripeptide-copper complex found in human plasma, saliva, and urine. It was first isolated in 1973 and has since become one of the most studied peptides for skin health, wound healing, and anti-aging applications.

GHK-Cu is known for its ability to stimulate collagen synthesis, promote wound healing, reduce inflammation, and enhance antioxidant defenses. Research has explored its applications in skin rejuvenation, hair follicle stimulation, nerve regeneration, and organ protection. It has gained the nickname "glow peptide" in biohacking communities for its skin benefits.

GHK-Cu comes in larger vials (commonly 50mg) because doses are measured in milligrams rather than micrograms. Reconstituting with 5ml of bacteriostatic water gives a concentration of 10,000 mcg/ml. A common injection dose of 1mg (1000mcg) requires just 0.1ml — 10 units on a 100-unit insulin syringe.

GHK-Cu can be administered subcutaneously, topically (as a cream or serum), or via intradermal injection. Subcutaneous injection is used for systemic effects, while topical application targets specific skin areas.

Frequently Asked Questions

Common injectable doses of GHK-Cu range from 1–3mg per day. For a 50mg vial + 5ml BAC water (10,000 mcg/ml), 1mg (1000mcg) = 0.1ml = 10 units.
Research protocols typically use 1–2mg per day via subcutaneous injection. Some protocols cycle 5 days on, 2 days off.
For hair growth research, some protocols use intradermal or subcutaneous injections near the scalp at 1–2mg per treatment, often 2–3 times per week.
Injectable GHK-Cu provides systemic distribution while topical targets surface layers. For skin aging, topical shows good absorption with high-quality formulations. For systemic effects (organ protection, systemic anti-aging), injection is studied more.
For a 50mg vial, add 5ml of bacteriostatic water to get 10,000 mcg/ml (10 mg/ml) concentration. Inject BAC water slowly along the glass wall. Gently swirl until the blue/teal copper complex is fully dissolved.
