GHK-Cu

GHK-Cu has not been approved by the U.S. Food and Drug Administration. It can only be prescribed through licensed clinicians where state law allows.

Yes, multiple clinical and cosmetic studies have evaluated GHK-Cu in human subjects, showing improvements in skin firmness, elasticity, and healing response. These trials have generally reported excellent tolerability and visible results with consistent use.

GHK-Cu appears to stimulate collagen and elastin production, improve skin texture and tone, and support tissue repair by delivering copper ions that activate key regenerative pathways. It also appears to help reduce signs of inflammation and oxidative stress that contribute to visible aging.

When used topically as directed, GHK-Cu is considered safe and well-tolerated. Most users experience no side effects, and any mild redness or tingling typically resolves quickly. As with any topical compound, sensitivity varies by individual skin type.

Individuals with known allergies to copper-based products, open wounds, or active skin infections should avoid use until cleared by a healthcare provider. Pregnant or breastfeeding women should consult a provider before starting any peptide-based regimen.

GHK-Cu is applied directly to clean, dry skin, most often as a serum, cream, or gel. It can be used once or twice daily, depending on formulation strength and individual treatment goals.

Yes, GHK-Cu is often paired with other regenerative peptides or skin therapies to enhance results. Growth-hormone secretagogues, like CJC-1295 + Ipamorelin or Tesamorelin, or supportive healing compounds like BPC-157 or TA1 + LL-37, complement this treatment. Any stack should be clinician-supervised.
