GHK-Cu (Copper Peptide) (100 mg Vial) Dosage Protocol

GHK-Cu is a copper-binding tripeptide (glycyl-L-histidyl-L-lysine) studied for skin remodeling, wound healing, and hair growth. Native plasma levels decline with age in parallel with regenerative capacity. This page covers the 100 mg vial.

Dosing & Reconstitution Guide

Educational guide for reconstitution and common dosing patterns

Standard / Conservative Approach (3 mL = 33.33 mg/mL; 5 days/week)

Week/PhaseDose per InjectionUnits (per injection) (mL)
Weeks 1-41.0 mg (1000 mcg)3 units (0.03 mL)
Weeks 5-81.5 mg (1500 mcg)4.5 units (0.045 mL)
Weeks 9-12+2.0 mg (2000 mcg)6 units (0.06 mL)

Frequency: Once daily, 5 days per week, progressing from 1.0 mg to 1.5 mg and then 2.0 mg as shown above. At 33.33 mg/mL, those doses equal 3, 4.5, and 6 U-100 units. Use a U-100 syringe with markings that clearly display every value in the table.

Reconstitution Steps

  1. Draw 3.0 mL of the protocol-specified sterile diluent with a sterile syringe.
  2. Add it slowly down the vial wall to reduce foaming.
  3. Gently swirl or roll until dissolved. Do not shake.
  4. Label the vial with the 33.33 mg/mL concentration, preparation date, and storage instructions.

Alternative Protocol (3 mL = 33.33 mg/mL; 3 times weekly)

Week/PhaseDose per InjectionUnits (per injection) (mL)
Weeks 1-12+2.0 mg (2000 mcg)6 units (0.06 mL)

Frequency: 2.0 mg three times per week, such as Monday, Wednesday, and Friday. At 33.33 mg/mL, each injection equals 6 U-100 units (0.06 mL), for approximately 6 mg per week.

Protocol Overview

GHK-Cu has both injectable and topical formulations, often used in combination — sub-Q for systemic effects and topical for direct skin/scalp application. Many cosmetic-research protocols use topical alone; injectable adds connective-tissue and wound-healing applications.

Storage Instructions

StateTemperatureDuration
Lyophilized−20°C (−4°F)Up to 24 months, dry & dark
Reconstituted2–8°C (35–46°F)Up to 30 days, protect from light

Important Notes

⚠ Research Use Only: GHK-Cu is investigational for sub-Q use. Topical formulations widely studied. Contraindicated with copper-overload disorders.

How This Works

GHK is a tripeptide (Gly-His-Lys) discovered in human plasma in 1973. Its bioactive form binds copper(II) to form GHK-Cu. Plasma levels decline from ~200 ng/mL in young adults to ~80 ng/mL by age 60, paralleling tissue regenerative decline.

GHK-Cu modulates over 4,000 human genes — stimulating collagen, elastin, and proteoglycan synthesis; activating Nrf2 antioxidant defense; upregulating stem-cell factor and dermal hair-follicle stem-cell activity; downregulating pro-inflammatory cytokines.
