Gene ActivationAnti-AgingCollagenRegeneration

What It Is

GHK-Cu is dual-listed here for its significant anti-aging properties. Beyond tissue repair, it activates genes associated with youthful gene expression patterns.

How It Works

Research shows GHK-Cu can shift gene expression patterns in older tissue toward a younger profile, affecting collagen, antioxidant defense, and cellular regeneration.

Who It's For

Those pursuing comprehensive longevity protocols. Excellent paired with telomere and mitochondrial peptides for a multi-pathway approach.

Who Should Avoid It

Avoid if allergic to copper. Generally very well-tolerated.

Protocol & Pricing

Pharmacy Price

$80

10mg/mL, 5mL vial (50mg total)

You pay pharmacy price. No markup.

Starting Dose

20 units (2mg)

Form

Injectable vial, 5mL

Your pharmacy label will read

GHK-CU

10 MG/ML (5 ML)

The label shows strength per mL, not the total in the vial.

What that means

  • 10mg/mL means 10mg in every mL.
  • The vial holds 5mL, so 10mg/mL × 5mL = 50mg in the vial.
  • Each 20-unit injection (0.2mL) gives you 2mg, about 25 injections per vial.

Dosing Protocol

20 units subcutaneous injection once daily, Monday to Friday (5 days on, 2 days off). 20 units = 0.2mL × 10mg/mL = 2mg per injection.

Beyond Use Date

90 Days from compounding (USP <797>)

A licensed U.S. 503A compounding pharmacy assigns this date and prints it on your vial label. Always follow the label.

Why this dose, and what the evidence shows

From our medical director's protocol for GHK-Cu. Where the evidence is thin, it says so.

Why this dose

The protocol uses injections five days per week followed by two days without treatment.

This schedule reflects clinical practice rather than a dosing schedule established in human trials.

Research has not established an optimal injected dose or maintenance schedule for cosmetic or connective-tissue outcomes.

What the evidence shows

GHK-Cu has been studied extensively in laboratory and animal research related to wound healing, collagen formation, tissue remodeling, and cellular repair.

Small human studies of topical copper-peptide products have also reported changes in collagen production and measures of skin appearance.

Evidence for injected GHK-Cu is much more limited.

No human clinical trial has established injected GHK-Cu as an effective treatment for skin appearance, recovery, wound healing, or connective-tissue repair.

The rationale for injection therefore comes primarily from preclinical research and the known biology of GHK-Cu rather than direct human clinical outcomes.

Each order also carries the $39 prescriber review. Pharmacy prices are the pharmacy's own; we add nothing to them.

All 2 GHK-Cu samples tested for sterility and endotoxin passed both. Latest sample received by the lab Oct 12, 2026.

Every GHK-Cu batch dispensed by a licensed U.S. 503A compounding pharmacy is independently tested by Eagle Analytical Services (FDA-registered, A2LA ISO 17025 accredited). Sterility testing checks that nothing grows in the sample; the USP <85> endotoxin test checks for bacterial toxins that can cause fever.

How to get GHK-Cu prescribed online

GHK-Cu is available by prescription after an online medical review and dispensed for human use by a licensed 503A pharmacy. That is what separates it from research-use-only vials sold without a prescription. There is no membership, just a medical review fee per order, and automatic refills are optional.

  1. 1

    Complete a $39 medical review. Answer a short intake about your health history and your goals for GHK-Cu. The $39 fee is the only charge Rx Peps Direct collects, paid once, not a recurring subscription.

  2. 2

    A licensed provider reviews it. A US-licensed clinician reviews your intake and, if GHK-Cu is appropriate for you, writes a patient-specific prescription. The starting dose is typically 20 units (2mg).

  3. 3

    The pharmacy compounds and ships it. A licensed 503A compounding pharmacy in Texas compounds GHK-Cu and ships it pre-reconstituted by FedEx overnight in a reusable cooled case. Your fill is a 5mL injectable vial at 10mg/mL (50mg total), labeled "GHK-CU 10 MG/ML (5 ML)", and you pay the pharmacy $80 per vial at wholesale, with no clinic markup, plus a $15 flat FedEx overnight shipping fee charged by the pharmacy.

Rx Peps Direct prescribes GHK-Cu in the 28 states plus Washington, DC where its medical team is licensed. Start your $39 medical review or browse the full Longevity & Anti-Aging range.

Common questions about GHK-Cu

Is the GHK-Cu under Longevity & Anti-Aging a different product?
No. It is the same product as the GHK-Cu listed under Recovery & Repair: the same a licensed U.S. 503A compounding pharmacy injectable vial (5 mL at 10 mg/mL, 50 mg total), the same price, and the same label. It is listed again under Longevity & Anti-Aging for protocols aimed at sustained cellular and skin health rather than acute wound or recovery support.
Is there a separate longevity formulation of GHK-Cu?
No. The active peptide, concentration, vial size and price are identical; there is no separate longevity formulation. The dose is the same from either listing: 20 units (2 mg) once daily, Monday to Friday. Only the goal differs: sustained cellular and skin health rather than acute repair.
How is GHK-Cu dosed for longevity protocols?
The Rx Peps Direct dose is 20 units (2 mg) on a U-100 insulin syringe, injected subcutaneously once daily, Monday to Friday (5 days on, 2 days off). It is the same dose as the Recovery & Repair listing. A licensed U.S. 503A compounding pharmacy compounds the formulation against Rx Peps Direct prescriptions; your provider confirms the protocol at review.
Where and how do I inject GHK-Cu?
Subcutaneously into the abdomen, upper outer thigh, or back of the upper arm using a 31-gauge, 5/16-inch needle on a U-100 insulin syringe. Sterile syringes are included with every Rx Peps Direct shipment. Rotate sites between injections.
How is GHK-Cu supplied?
Compounded by a licensed U.S. 503A compounding pharmacy under a patient-specific prescription. Ships pre-reconstituted and ready to inject in cold-chain packaging. Every batch is tested by Eagle Analytical Services for sterility and bacterial endotoxin; the Certificate of Analysis is published on this product page.
