What is GHK-cu Peptide?

GHK-Cu (glycyl-L-histidyl-L-lysine with copper) is a naturally occurring peptide that plays a vital role in wound healing, tissue repair, and skin regeneration. It was first identified in human plasma and is now widely studied for its regenerative properties. When combined with copper (Cu), it forms a potent complex that offers a range of benefits—particularly in skin health and anti-aging.

GHK-Cu works by binding to copper ions, which are critical for a number of biological processes. Once inside the body, GHK-Cu promotes collagen synthesis, elastin production, and tissue remodeling. This makes it especially beneficial for reducing wrinkles, improving skin elasticity, and accelerating wound healing. Additionally, it has anti-inflammatory properties, which help reduce redness and irritation.

In terms of dosing, GHK-Cu is often administered via subcutaneous injection. Typical injectable doses range from 100 micrograms to 500 micrograms per day, though exact dosing may vary depending on individual goals and professional guidance. These injections are typically administered daily or a few times per week, depending on the therapeutic protocol. Consistency in dosing is key to optimizing its regenerative effects.

The advantages of GHK-Cu include its natural origin, safety profile, and ability to work across multiple tissues—not just skin, but also hair, muscles, and internal organs. Its mechanism of action involves binding to cell surface receptors, which trigger the release of growth factors and initiate repair processes. This makes GHK-Cu a favorite in both clinical and cosmetic settings—used for anti-aging, scar reduction, and promoting overall tissue vitality.
