GHK-Cu Dosage Protocol

Quick Start

The short version

If you only read one thing, read this. The four cards below are the whole protocol in plain English — the sections that follow just add the detail.

Dosage Chart

Handling

Dosing & Reconstitution Guide

Add 6.0 mL of bacteriostatic water slowly down the inner wall of the 180 mg vial. Do not shake — swirl gently until the powder fully dissolves into a uniform deep-blue solution. At 30 mg/mL, 1 mg equals ~3.3 units (0.033 mL) on a U-100 insulin syringe.

Subcutaneous Protocol

Frequency: once daily subcutaneously. GHK-Cu has a short circulating half-life (minutes), but downstream signaling effects on gene expression are reported to persist far longer, so daily single dosing is standard in reference protocols.

Supplies Needed

Plain-English Glossary

Jargon, translated

A quick decoder for the terms you'll see across this page.

Subcutaneous (subQ)

Injected into the fatty layer just under the skin — not into muscle or vein. Easier and less painful than an IM shot.

Reconstitution

Mixing a dry powder with liquid (bacteriostatic water) to turn it into an injectable solution.

Lyophilized

Freeze-dried. The peptide arrives as a dry powder so it stays stable during shipping.

Bacteriostatic water

Sterile water with a tiny amount of preservative that prevents bacteria growth — used to mix peptides.

Units (on an insulin syringe)

The small tick marks on a U-100 syringe. 100 units = 1 mL. Most doses are just a few units.

Half-life

How long it takes your body to clear half of a dose. Guides how often you inject.

Titration

Starting low and slowly increasing the dose so your body can adjust.

Protocol Overview

• Goal: Support tissue remodeling and antioxidant signaling through copper-peptide activity.
• Schedule: Daily subcutaneous injection, typically evening.
• Dose range: 1–3 mg per administration in reported protocols.
• Storage: 2–8 °C after reconstitution, protected from light.

Dosing Protocol

• Start: 1 mg once daily to assess tolerance.
• Target: 2 mg once daily as a standard reference dose.
• Timing: Evening administration is common — aligns with overnight repair cycles.
• Cycle length: Reference protocols run 4–8 weeks, then reassess.

Storage Instructions

• Lyophilized product: room temperature, sealed and protected from light. Refrigeration acceptable.
• Reconstituted product: 2–8 °C (35.6–46.4 °F) refrigerated, protected from light.
• Do not freeze reconstituted solution.
• Allow to reach room temperature before administration to reduce injection-site response.

Important Notes

• Use a new sterile syringe for each administration.
• Rotate injection sites (abdomen, thighs, upper arms) to reduce local irritation.
• Discard the vial if the solution becomes cloudy, discolored, or shows particulates.
• Document daily dose and site rotation for consistency.
• Solution should remain a clear deep blue — discoloration or particulates indicate degradation.

Mechanism

How This Works

Potential Benefits & Side Effects

• Associated with improved skin firmness, elasticity, and reduced photo-damage in dermatological studies.
• Reported wound-healing acceleration and reduced scar formation in animal models.
• Investigated for hair follicle enlargement and hair-shaft thickening.
• Antioxidant and anti-inflammatory activity via copper regulation.
• Generally well tolerated; occasional injection-site redness or transient warmth.
• Long-term human safety data at injectable doses is limited; investigational.

Lifestyle Factors

• Maintain adequate protein intake to supply amino-acid substrates for collagen synthesis.
• Prioritize sleep — dermal repair is heavily circadian.
• Use broad-spectrum UV protection; GHK-Cu research often pairs with photo-damage reduction.
• Balance dietary copper and zinc; avoid excessive supplemental copper on top of GHK-Cu.

Injection Technique

1. 1. Clean the vial septum and injection site with alcohol; allow to dry.
2. 2. Draw the target volume slowly to avoid foaming the peptide.
3. 3. Pinch a skinfold; insert the needle at 45–90° into subcutaneous tissue.
4. 4. Do not aspirate for subcutaneous injections; inject slowly and steadily.
5. 5. Rotate sites systematically (abdomen, thighs, upper arms) to avoid lipohypertrophy.
