# How to Use GHK-Cu Copper Peptide: Dosing Protocol & Guide

**By TelosRX Editorial Team** · 2026-08-10

**GHK-Cu (copper peptide) is used in research protocols for skin regeneration, wound healing, and tissue repair. This step-by-step guide covers reconstitution, dosing, injection technique, cycle structure, and monitoring — all subject to provider approval at [TelosRX](https://telosrx.com).**

## Step 1: Understand What GHK-Cu Is and What Research Shows

GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a naturally occurring tripeptide found in human plasma, saliva, and urine. Copper chelation gives it a distinct biological profile: it binds to copper ions and acts as a signaling molecule involved in tissue repair and regeneration.

Peer-reviewed research has examined GHK-Cu across several domains:

-   **Collagen synthesis:** Studies in the _Journal of Investigative Dermatology_ (accessible via [pubmed.ncbi.nlm.nih.gov](https://pubmed.ncbi.nlm.nih.gov)) have found GHK-Cu stimulates fibroblast activity and collagen I and III production in dermal tissue.
-   **Wound healing:** Animal studies show accelerated wound closure and reduced scar formation with topical and systemic GHK-Cu.
-   **Anti-inflammatory signaling:** GHK-Cu has been shown to downregulate inflammatory cytokines including TNF-alpha in cell culture models.

GHK-Cu is not FDA-approved as a drug. Compounded preparations are prepared under federal compounding regulations and are subject to evaluation by a licensed provider before any protocol begins.

## Step 2: Gather Your Supplies Before Reconstitution

Before reconstituting GHK-Cu, confirm you have all required materials. Missing a component makes the process unsafe:

-   GHK-Cu lyophilized powder vial (from your compounding pharmacy)
-   Bacteriostatic water (BAC water) for injection — not sterile water, not saline
-   1 mL or 3 mL syringes for reconstitution
-   Insulin syringes (typically 0.5 mL, 29–31 gauge) for subcutaneous injection
-   Alcohol swabs (70% isopropyl)
-   Sharps disposal container
-   Your provider-approved protocol document specifying vial concentration and per-dose volume

Do not substitute BAC water with tap water, sterile saline, or any other diluent unless explicitly specified by your provider. BAC water's 0.9% benzyl alcohol content preserves the peptide between injections.

## Step 3: Reconstitute the Vial Correctly

GHK-Cu arrives as a lyophilized (freeze-dried) powder that must be dissolved before use. Incorrect reconstitution degrades the peptide.

1.  Wipe the rubber stopper of both the GHK-Cu vial and BAC water vial with an alcohol swab. Allow to air-dry for 15 seconds.
2.  Draw the specified volume of BAC water into your reconstitution syringe. Your provider protocol will specify how many mL to add based on the vial dose and desired concentration (e.g., 2 mg vial + 2 mL BAC water = 1 mg/mL).
3.  Insert the needle at an angle and allow the BAC water to run slowly down the inside wall of the vial — do not aim it directly at the powder.
4.  Remove the syringe. Gently swirl the vial in slow circles for 20–30 seconds until the powder is fully dissolved. The solution should be clear or very light blue.
5.  Do not shake. Agitation can degrade peptide bonds.
6.  Label the vial with the date of reconstitution and concentration.

Reconstituted GHK-Cu is typically stable for 28–30 days when refrigerated at 2–8°C. Do not freeze a reconstituted vial.

## Step 4: Calculate Your Dose and Draw the Correct Volume

Dose calculation prevents over- or under-dosing. The formula is straightforward:

**Volume to draw (mL) = Desired dose (mg) ÷ Concentration (mg/mL)**

Example: If your vial is reconstituted at 1 mg/mL and your protocol calls for 1 mg per injection, draw 1.0 mL. If the concentration is 2 mg/mL and the dose is 1 mg, draw 0.5 mL.

Always verify the calculation against your provider's written protocol before drawing. If there is any discrepancy, contact your care team through the TelosRX platform before injecting.

## Step 5: Inject Subcutaneously Using Correct Technique

GHK-Cu protocols typically call for subcutaneous (SubQ) injection — into the fat layer just under the skin, not into muscle.

1.  Choose an injection site: lower abdomen (at least 2 inches from the navel), lateral thigh, or back of upper arm.
2.  Wipe the site with an alcohol swab and allow to air-dry.
3.  Pinch a small fold of skin between your thumb and index finger.
4.  Insert the insulin syringe needle at a 45-degree angle (or 90 degrees if using a very short 4–5 mm needle) into the pinched fold.
5.  Slowly depress the plunger over 5–10 seconds to minimize discomfort.
6.  Withdraw the needle at the same angle it entered. Apply gentle pressure with a dry cotton swab — do not rub.
7.  Dispose of the needle immediately in your sharps container.

Rotate injection sites with each administration. Using the same site repeatedly can cause lipodystrophy — localized fat loss or hardening of tissue at the injection site.

## Step 6: Follow the Protocol Cycle and Monitor for Response

Research protocols for GHK-Cu vary by indication. Common structures include:

-   **Daily injection cycles:** Some protocols call for daily SubQ injections for 4–8 weeks followed by a 2–4 week rest period.
-   **Three-times-per-week cycles:** Alternating-day administration with weekend breaks, often used for skin and collagen-focused protocols.

Monitoring signs to track and report to your provider:

-   Any injection site reactions: persistent redness, swelling, or hardness beyond 24 hours
-   Systemic symptoms: headache, nausea, or flushing following injection
-   Unexpected changes in skin, wound healing, or inflammation markers (if applicable)

All protocols are managed through asynchronous provider check-ins via the TelosRX platform. You submit updates through the patient portal; your provider reviews and responds without requiring a scheduled appointment.

## Frequently Asked Questions

### What is the standard GHK-Cu dosage?

Research protocols typically use 1–2 mg of GHK-Cu administered subcutaneously per injection, with frequency ranging from daily to three times per week depending on the indication. Dosing is subject to provider evaluation and individual protocol.

### How do you reconstitute GHK-Cu?

GHK-Cu is typically supplied as a lyophilized powder and reconstituted with bacteriostatic water. Add BAC water slowly down the inside wall of the vial and gently swirl — never shake — until fully dissolved.

### Where do you inject GHK-Cu subcutaneously?

Common subcutaneous injection sites include the lower abdomen (2 inches from the navel), the lateral thigh, and the back of the upper arm. Sites should be rotated with each injection to prevent tissue irritation.

### Is GHK-Cu FDA-approved?

No. GHK-Cu is not FDA-approved as a drug. It is available as a compounded preparation under federal compounding regulations, subject to evaluation and approval by a licensed provider.
