GHK-Cu 100 mg— Research Protocol

Quickstart Highlights

GHK-Cu dosage protocols utilize this naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine) to support skin rejuvenation, wound healing, and tissue repair^[1][2]. GHK-Cu stimulates collagen and elastin production, promotes angiogenesis, and delivers powerful antioxidant and anti-inflammatory benefits^[3][4]. Human studies demonstrate improved skin thickness, reduced wrinkles, and enhanced dermal density with GHK-Cu application^[2].

Storage Instructions

Proper storage preserves peptide quality.

• Lyophilized: Store at −20 °C (−4 °F) in dry, dark conditions; stable for 12+ months^[6].
• Reconstituted: Refrigerate at 2–8 °C (35.6–46.4 °F); use within 30 days; avoid freeze–thaw^[7].
• Allow vials to reach room temperature before opening to reduce condensation uptake.

How It Works

GHK-Cu functions as a “signal peptide” that triggers tissue repair processes by chelating copper(II) ions and delivering this essential trace metal to cells in a bioavailable form^[1][9]. Copper is a critical cofactor for enzymes involved in collagen synthesis (lysyl oxidase) and antioxidant defense (superoxide dismutase). Genomic studies show GHK-Cu modulates over 30% of human genes toward a regenerative, anti-aging phenotype^[2][10]. The peptide stimulates production of VEGF and bFGF in fibroblasts, promoting angiogenesis and blood flow to injured tissue^[3]. GHK-Cu also recruits immune cells to injury sites, increases collagen/elastin/glycosaminoglycan synthesis, and regulates matrix metalloproteinases for balanced tissue remodeling^[2][4].

Potential Benefits & Side Effects

Observations from preclinical and clinical literature.

• Skin Rejuvenation: Clinical studies show increased skin thickness, improved dermal collagen density, and reduced wrinkle depth with GHK-Cu application^[2].
• Wound Healing: Promotes angiogenesis, granulation tissue formation, and accelerated wound closure in preclinical models^[3][4].
• Anti-Inflammatory: Suppresses pro-inflammatory cytokines (TNF-α, IL-6) and provides antioxidant protection^[1][11].
• Hair Growth: Observed to enlarge hair follicle size and increase growth rate in studies^[2].
• Safety Profile: Excellent tolerability with no serious adverse effects noted; extremely wide safety margin in toxicology studies^[9][10].
• Occasional mild injection-site reactions (transient redness or stinging) may occur with subcutaneous administration.
