GHK-Cu
Activates 4,000+ genes involved in regeneration, with particular relevance to age-related tissue decline.
Medically reviewed by Dr. Jonathan Snipes, MD. Last reviewed May 6, 2026.
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.

GHK-Cu is available by prescription through a licensed telehealth visit and dispensed for human use by a named 503A pharmacy. That is what separates it from research-use-only vials sold without a prescription. There is no subscription and no membership, just a one-time visit fee.

Common questions about GHK-Cu
- What is the GHK-Cu longevity formulation?
- The GHK-Cu longevity formulation is a variant of the standard GHK-Cu compounded injectable optimized for longevity protocols rather than acute wound or recovery support. The active ingredient (the GHK-Cu copper tripeptide) is the same; the formulation differs in concentration or carrier choice to support sustained, lower-frequency dosing patterns characteristic of longevity protocols.
- How is it different from the standard GHK-Cu?
- Same active peptide, formulation tuned for longevity-style dosing. Standard GHK-Cu is typically used for acute or sub-acute recovery (4 to 8 week protocols at higher daily doses). The longevity variant supports lower-frequency, longer-duration protocols where the goal is sustained cellular and skin health rather than acute repair.
- How is the longevity formulation dosed?
- Common longevity protocols deliver 1 to 2 mg subcutaneously 2 to 3 times per week, run continuously over 12 to 24 weeks at a time. Optimal Balance Pharmacy compounds the formulation against RxPepsDirect prescriptions; your provider sets the protocol based on your longevity goals.
- Where and how do I inject the longevity 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 RxPepsDirect shipment. Rotate sites between injections.
- How is the formulation supplied?
- Compounded by Optimal Balance Pharmacy under a 503A 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.
