OVERVIEW

GHK‑Cu 50 mg (Copper Peptide) is a small, naturally occurring tripeptide composed of glycyl‑histidyl‑lysine bound to a copper ion. It plays a significant role in tissue repair, skin regeneration, and cellular signaling. Research has demonstrated that GHK‑Cu can stimulate collagen and elastin synthesis, promote wound healing, and support extracellular matrix remodeling. In addition, it exhibits antioxidant and anti-inflammatory properties, which help protect cells from oxidative stress and environmental damage. GHK‑Cu has been investigated in both topical and systemic applications, with particular focus on its ability to improve skin firmness, elasticity, and overall appearance, as well as its potential to accelerate repair in damaged tissues. Its small molecular size allows it to penetrate tissues efficiently and interact with fibroblasts, keratinocytes, and other skin cells in experimental models. (peptidecience.com)

Despite its promising preclinical and cosmetic research, GHK‑Cu 50 mg is not approved by the U.S. Food and Drug Administration for therapeutic use. Most evidence comes from laboratory studies, animal models, or small human trials, and its long-term safety, efficacy, and optimal dosing in humans remain uncertain. Products marketed as GHK‑Cu are typically labeled for research or cosmetic use only and are not manufactured to pharmaceutical-grade standards, meaning purity and potency can vary. Self-administration outside of controlled research or clinical settings carries potential risks, including irritation or unknown systemic effects. Individuals interested in the peptide for skin health, tissue repair, or anti-aging purposes should consult qualified healthcare professionals and rely on evidence-based interventions rather than unregulated compounds.
