GHK-Cu (Copper Tripeptide-1)
Also known as: GHK-copper, Copper tripeptide-1, Copper peptide, Glycyl-L-histidyl-L-lysine copper, GHK-Cu peptide, Cu-GHK, Prezatide copper acetate
GHK-Cu is a complex of copper ions bound to the tripeptide glycyl-L-histidyl-L-lysine (GHK). GHK is a small peptide that occurs naturally in human plasma, saliva, and urine, and it was first isolated from human blood in the 1970s. In cosmetic products it is commonly listed as copper tripeptide-1. Reported plasma levels of GHK in humans decline with age, which has prompted research interest in its biological roles.
Often sold in blends: Glow, Klow.
How it works
Published research describes GHK as a copper-binding peptide that can carry copper, a cofactor for enzymes involved in tissue repair. Laboratory and animal studies report that GHK-Cu can influence the expression of genes tied to collagen and extracellular matrix production, tissue remodeling, and antioxidant and anti-inflammatory pathways. These mechanisms are drawn largely from in vitro and preclinical models, and how fully they translate to human outcomes has not been established.
Researched uses
- Studied for skin wound healing and tissue repair in preclinical and early clinical settings
- Studied for stimulating collagen and extracellular matrix production in skin models
- Studied for reducing signs of skin aging such as fine lines and elasticity in small topical trials
- Studied for antioxidant and anti-inflammatory effects in laboratory models
- Studied for hair follicle and scalp effects in preliminary research
- Investigated for broader tissue-regeneration and gene-modulation properties in laboratory studies
GHK-Cu is not an FDA-approved drug for any medical condition. It is widely used as a cosmetic ingredient in topical skin and hair products, where it is regulated as a cosmetic rather than a drug and where no treatment or disease claims are permitted. It has also appeared in wound-care and dermatologic research. Injectable or "research use only" GHK-Cu products sold online are not FDA-approved, are not part of the licensed pharmacy system, and are unregulated for purity, identity, and sterility. There is no established FDA-approved prescription form of injectable GHK-Cu.
GHK-Cu (Copper Tripeptide-1) providers compared
Providers that have passed our rubric review are listed first, then ordered by the total cost of a 3-month protocol. We average every cost to a standard 3-month protocol, which our medical advisors consider the best basis for comparing cost and value, and the headline figure folds in any one-time consult or provider-review fee plus three months of membership. Use the calculator below to adjust the length and see the same total broken out.

We average every cost to a standard 3-month protocol, which our medical advisors consider the best window for comparing cost and value. Monthly plans are multiplied by 3 and 3-month programs are taken as billed; each provider's own sticker price and cadence are shown underneath.
The headline figure is the total 3-month cost: the medication plus any one-time consult or provider-review fee (for example RxPepsDirect's $39) and three months of any membership fee. Where a fee is not published we fold in what is known and flag that other fees may apply.
Per-vial providers are averaged to a 3-month protocol at roughly one vial per month (3 vials), marked "est.", with the per-vial price shown underneath. Actual vial count depends on your dose and protocol.
Prices are gathered from each provider's public pages. The "Verified" date is when we last checked the provider's sticker price; for per-vial providers it is the vial price that was verified, not the averaged 3-month total.
Value check: total cost of therapy
This is the real value comparison. A sticker price hides consult and membership fees, so this adds everything up for a full protocol of GHK-Cu (Copper Tripeptide-1) and ranks by true total cost. We default to a 3-month protocol, the window our medical advisors consider best for judging value.
Per-vial providers are estimated at about one vial per month (3 vials for 3 months), plus any one-time consult. Actual vial count depends on your dose and protocol, so the real cost may run higher or lower.
Safety notes
Topical GHK-Cu in cosmetic products is generally reported to be well tolerated, with possible skin irritation, redness, or contact sensitivity in some users. Safety data for injectable or high-dose systemic use in humans is limited, and copper-containing compounds carry theoretical concerns about copper accumulation. Products sold outside the licensed pharmacy system, including "research use only" injectables, are not tested or verified for identity, purity, or sterility, so their actual content and safety cannot be assured.
GHK-Cu (Copper Tripeptide-1) questions
How much does GHK-Cu (Copper Tripeptide-1) cost?
Across the licensed providers tracked here, a full 3-month protocol of GHK-Cu (Copper Tripeptide-1) totals $279 to $576, depending on the provider, dose, and what is included. We average every cost to a standard 3-month protocol, which our medical advisors consider the best basis for comparing cost and value, and the total folds in any one-time consult or provider-review fee and three months of membership. Each price shows the date the provider's sticker price was verified.
Is GHK-Cu an approved medication?
No. GHK-Cu is not FDA-approved as a drug. It is used mainly as a cosmetic ingredient in topical skin and hair products and has been studied in wound-care and dermatology research, but it is not an approved treatment for any medical condition.
What does the research on GHK-Cu actually show?
Most evidence comes from laboratory and animal studies, plus some small human trials of topical products. This research suggests possible roles in collagen production, tissue repair, and antioxidant activity, but large, well-controlled human trials confirming clinical benefit are limited. Many claimed effects remain unproven.
How is GHK-Cu typically used, and how do cost and access vary?
It is most commonly applied topically as an ingredient in over-the-counter cosmetic creams and serums, which are widely available. Injectable versions marketed online as research chemicals are unregulated and fall outside the licensed pharmacy and prescription system. Cost and availability differ by product type and source, and unregulated products carry added quality and safety uncertainty.
