GHK-Cu — 100mg protocol. Edit the doses below for the 100mg vial.
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]. This educational protocol presents a once-daily subcutaneous approach using a practical dilution for clear insulin-syringe measurements.
-
Reconstitute: Add 3.0 mL bacteriostatic water → ~33.3 mg/mL concentration.
-
Typical daily range: 1–2 mg once daily (gradual titration over 12 weeks).
-
Easy measuring: At 33.3 mg/mL, 1 unit = 0.01 mL ≈ 333 mcg on a U-100 insulin syringe.
-
Storage: Lyophilized: freeze at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F); use within 30 days.

Frequency: Inject once daily subcutaneously, 5 days per week (Mon–Fri) with weekends off[5]. For ≤10-unit (≤0.10 mL) administrations, consider 30- or 50-unit insulin syringes for improved readability.
Reconstitution Steps
- Draw 3.0 mL bacteriostatic water with a sterile syringe.
- Inject slowly down the vial wall; avoid foaming.
- Gently swirl/roll until dissolved (do not shake).
- Label and refrigerate at 2–8 °C (35.6–46.4 °F), protected from light; use within 30 days[6][7].
Alternative Protocol (3 mL = 33.3 mg/mL; 3× weekly)
Frequency: Inject 2 mg three times per week (e.g., Monday/Wednesday/Friday)[6]. This protocol maintains consistent weekly dosing (~6 mg/week) with less frequent injections.
Supplies Needed
Plan based on an 8–12 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.
- 8–12 weeks (1 vial): 3 mL → 1 × 10 mL bottle
-
Alcohol Swabs: One for the vial stopper + one for the injection site each day.
- Per week: 10 swabs (2/day, 5 days)
- 8 weeks: 80 swabs → recommend 1 × 100-count box
- 12 weeks: 120 swabs → recommend 2 × 100-count boxes
Protocol Overview
Concise summary of the once-daily regimen.
-
Goal: Support skin rejuvenation, collagen synthesis, wound healing, and anti-aging tissue repair[2][3].
-
Schedule: Daily subcutaneous injections, 5 days on / 2 days off, for 8–12 weeks.
-
Dose Range: 1–2 mg daily with gradual titration.
-
Reconstitution: 3.0 mL per 100 mg vial (~33.3 mg/mL) for accurate unit measurements.
-
Storage: Lyophilized frozen at −20 °C; reconstituted refrigerated; use within 30 days.
Dosing Protocol
Suggested daily titration approach.
-
Start: 1.0 mg daily for Weeks 1–4; increase to 1.5 mg for Weeks 5–8.
-
Target: 2.0 mg daily by Weeks 9–12.
-
Frequency: Once per day (subcutaneous), 5 days per week.
-
Cycle Length: 8–12 weeks; take 2–4 weeks off before repeating[5].
-
Timing: Any consistent time; rotate injection sites.
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.
