GHK-Cu is a naturally occurring copper peptide that has the best human evidence as a topical skin-care ingredient for firmness, fine lines and skin repair. Injectable GHK-Cu is a different matter: there are no controlled human trials, and as of October 2026 the FDA has not yet reviewed it for compounding. Dr. David Nazarian in Beverly Hills helps patients separate the well-supported uses from the speculative ones.
What Is GHK-Cu?
GHK is a three-amino-acid peptide (glycine, histidine and lysine) found in human blood, saliva and urine. It binds copper tightly, forming GHK-Cu. Levels are reported to be higher in young adults than in older adults. In the laboratory, GHK-Cu influences genes and proteins involved in collagen production, tissue remodeling and inflammation, which is why it is studied for skin aging and wound healing.
Topical GHK-Cu: Skin and Scalp
Copper peptides have been used in cosmetic creams and serums for decades. Small clinical studies of topical products report improvements in skin firmness, fine lines, texture and thickness over weeks to months, and some studies combine GHK-Cu with microneedling. These studies are generally small and often industry-funded, but topical use has a long safety record.
For hair, GHK-Cu appears in scalp products marketed for thinning. Evidence in people is limited, and it should not replace proven hair-loss treatments.
Injectable GHK-Cu
Injected GHK-Cu is promoted online for whole-body anti-aging, recovery and skin. These claims come from laboratory and animal data. There are no published randomized human trials of injected GHK-Cu, so dosing, benefits and long-term effects are not established. Reported side effects include injection-site pain and irritation, and copper exposure is a consideration for people with liver disease or copper-handling disorders.
FDA and Compounding Status (October 2026)
- Topical GHK-Cu is sold as a cosmetic ingredient.
- Injectable GHK-Cu was placed in FDA Category 2 in 2023 and removed in April 2026 after the nomination was withdrawn.
- The FDA’s Pharmacy Compounding Advisory Committee is expected to review GHK-Cu at a meeting planned before the end of February 2027. Until then, injectable GHK-Cu is not formally on the compounding list.
How Dr. Nazarian Approaches Skin and Longevity Goals
For skin aging, the most reliable foundations remain daily sunscreen, a prescription retinoid when tolerated, and in-office treatments with good evidence. Topical copper peptides can be a reasonable addition. For whole-body longevity goals, Dr. Nazarian focuses first on the measurable drivers of healthy aging described on our longevity medicine page.

Typical Peptide Treatment Schedule
When an injectable peptide is part of your plan, Dr. Nazarian typically prescribes it at night, five nights a week, Monday through Friday, with weekends off, for an eight-week course followed by a two-week break so the body does not adapt to it. The specific product, dose and length of treatment are discussed individually.
Frequently Asked Questions
Where can I get GHK-Cu in Los Angeles?
Topical copper peptide products are widely available. For a medical plan, including discussion of injectable GHK-Cu, start with an evaluation at My Concierge MD in Beverly Hills, where Dr. Nazarian reviews benefits, risks and FDA status.
How much does GHK-Cu treatment cost in Beverly Hills?
Cost depends on the evaluation, any lab tests and the treatment plan. A new-patient consultation with Dr. Nazarian is $450. Lab tests and any treatment are priced separately, and our team gives you those costs before testing begins.
Does GHK-Cu really increase collagen?
Laboratory studies show effects on collagen production, and small human studies of topical products report firmer, smoother skin. Larger independent trials would strengthen the case.
Is injectable GHK-Cu safe?
It has not been tested in controlled human trials, so its safety is not established. Products bought online may vary in purity and dose.
Can I use GHK-Cu with retinoids or vitamin C?
Many people do, though some prefer to apply strong acids and copper peptides at different times of day to reduce irritation. Ask about your specific routine.
