1. Draw 2.5 mL of bacteriostatic water with a sterile syringe.
2. Inject slowly down the vial wall; avoid foaming.
3. Gently swirl or roll until dissolved (do not shake).
4. Label and refrigerate at 2 to 8 °C, protected from light; use within 30 days. At 20 mg/mL, 1 unit = 0.01 mL » 200 mcg on a U-100 insulin syringe.

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. 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. The peptide stimulates production of VEGF and bFGF in fibroblasts, promoting angiogenesis and blood flow to injured tissue. GHK-Cu also recruits immune cells to injury sites, increases collagen, elastin, and glycosaminoglycan synthesis, and regulates matrix metalloproteinases for balanced tissue remo

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