GHK-Cu (100 mg vial)

Protocol Overview

Concise summary of the regimen.

Dosing & Reconstitution

Frequency: Inject once daily subcutaneously, 5 days per week (Mon to Fri) with weekends off. For 10-unit (0.10 mL) or smaller administrations, consider 30- or 50-unit insulin syringes for improved readability.

Reconstitution Steps

1. Draw 3.0 mL 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 33.3 mg/mL, 1 unit = 0.01 mL » 333 mcg on a U-100 insulin syringe.

Storage Instructions

Proper storage preserves peptide quality.

• Lyophilized: store at -20 °C (-4 °F) in dry, dark conditions; stable for 12+ months.
• Reconstituted: refrigerate at 2 to 8 °C; use within 30 days; avoid freeze-thaw.
• Allow vials to reach room temperature before opening to reduce condensation uptake.

Supplies Needed

Plan based on an 8 to 12 week daily protocol (5 days/week) with gradual titration.

Peptide Vials (GHK-Cu, 100 mg each):

• 8 weeks (~40 injections, ~50 mg total) » 1 vial.
• 12 weeks (~60 injections, ~90 mg total) » 1 vial.

Insulin Syringes (U-100, 30- or 50-unit preferred):

• Per week: 5 syringes (1/day, 5 days).
• 8 weeks: 40 syringes. 12 weeks: 60 syringes.

Bacteriostatic Water (10 mL bottles):

• Use 3.0 mL per vial for reconstitution.
• 8 to 12 weeks (1 vial): 3 mL needs 1 x 10 mL bottle.

Alcohol Swabs (vial stopper + injection site each day):

• Per week: 10 swabs (2/day, 5 days).
• 8 weeks: 80 swabs (1 x 100-count box). 12 weeks: 120 swabs (2 x 100-count boxes).

Important Notes

Practical considerations for consistency and safety.

• Use new sterile insulin syringes (30- or 50-unit recommended for small volumes); dispose in a sharps

container.

• Rotate injection sites (abdomen, thighs, upper arms) to reduce local irritation.
• Inject slowly; wait a few seconds before withdrawing the needle.
• Document daily dose and site rotation to maintain consistency.
• Reconstituted solution should appear clear with a blue tint (from copper); discard if cloudy or discolored.

How This 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. 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 remodeling.

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.

• 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.

Lifestyle Factors

Complementary strategies for best outcomes.

• Ensure adequate protein and vitamin C intake to support collagen synthesis.
• Maintain proper hydration; tissue repair processes require sufficient water.
• Consider complementary skincare routines (sunscreen, moisturizers) to protect treated skin.
• Prioritize sleep and stress management to support recovery and tissue regeneration.

Injection Technique

General subcutaneous guidance from clinical best-practice resources.

1. Clean the vial stopper and skin with alcohol; allow to dry.
2. Pinch a skinfold; insert the needle at 45 to 90 degrees into subcutaneous tissue.
3. Do not aspirate for subcutaneous injections; inject slowly and steadily.
4. Wait 5 to 10 seconds before withdrawing; dispose of syringe in sharps container.
5. Rotate sites systematically (abdomen, thighs, upper arms) to avoid lipohypertrophy.
