GHK-Cu
Copper peptide for skin, hair, and tissue repair
GHK-Cu is a naturally occurring peptide bound to copper that drops to 40% of its youthful levels by the age of 60. This decline is directly linked to aging markers like thinner skin and loss of elasticity, but systemic administration through subcutaneous injection can help restore dermal thickness.
Injecting this peptide can significantly increase the production of collagen and elastin, leading to a more youthful appearance.
For reconstitution, a 50 mg vial is typically mixed with 5 mL of bacteriostatic water, meaning 10 units on a standard insulin syringe delivers a 1 mg dose. Most injectable protocols call for 1-2 mg daily, though some users scale up to 4 mg depending on their specific research goals. It is vital that the solution remains a light blue color; if it turns green or dark, it has oxidized and must be discarded. Users commonly follow a cycle of 3 months on followed by 3 months off to avoid disrupting the body's zinc and copper balance.
Constant systemic use without breaks can cause the body to struggle with processing zinc, so supplemental zinc is often necessary to keep these ratios intact. This peptide is frequently paired with BPC-157 and TB-500 in a combination known as a GLOW stack to provide a comprehensive approach to both tissue repair and aesthetic rejuvenation.
