What Does the Research Say?

Decades of research. Stimulates collagen and glycosaminoglycan synthesis; accelerates wound healing; promotes hair follicle growth; antioxidant and anti-inflammatory effects. GHK-Cu declines ~60% with age, making supplementation compelling for seniors. Used in veterinary dermatology topically and gaining traction orally/injectable.

🩺 Administration: Available topical (creams, serums), oral (supplements), and injectable. Topical best for localized skin/wounds. Oral for systemic support. Injectable for highest bioavailability. Vet can help determine best format.

Side Effects & Safety

Excellent safety as a naturally occurring peptide. Rare mild effects: possible skin irritation from topical carriers (not the peptide itself), mild GI upset with oral. Dogs with copper storage disorders (Bedlington Terriers, some Labs) should use only under vet supervision with liver monitoring.

⚠️ Tumor Caution: Peptides promoting tissue repair could theoretically accelerate existing tumors. Vet screening recommended before starting, especially for seniors and cancer-prone breeds.
