Copper tripeptide-1

**Status:** Not FDA-approved · topical only · Prescription only

**How it is delivered:** Gel or cream — once or twice daily, continuous.

GHK-Cu — glycyl-L-histidyl-L-lysine bound to a copper(II) ion — is a three-amino-acid sequence that exists naturally in human plasma. It was isolated there in 1973, and the body keeps making it across the lifespan, just less of it as you age. Plasma levels run around 200 ng/mL in your twenties and drop to roughly 80 ng/mL by 60.

The molecule works by delivering bioavailable copper to copper-dependent enzymes — lysyl oxidase (which crosslinks collagen and elastin), superoxide dismutase (a primary antioxidant defense), and others. Beyond copper delivery, GHK-Cu upregulates genes encoding collagen types I, III, IV, and VII, promotes fibroblast and keratinocyte proliferation, and increases VEGF expression, which drives angiogenesis. The anti-inflammatory side runs through NFκB suppression. That’s a lot of biological levers for a small molecule.

> “GHK-Cu is the peptide that turned cosmetic chemistry toward copper — not because copper was new, but because the tripeptide delivers it where collagen synthesis happens.”

Most of the human evidence so far comes from topical cosmetic use for skin firmness, fine lines, and collagen markers. The deeper systemic claims — joint repair, cognitive enhancement, broad anti-aging — rest on preclinical work and gene-expression analysis; the human trials for those uses don’t exist yet. The full mechanistic story and trial list live on our PeptideWellness deep-dive.

## Who it's for (or who should avoid)

### What it's aimed at

GHK-Cu protocols are most commonly prescribed for:

- **Photoaged skin** — fine lines, coarse wrinkles, mottled pigmentation, loss of firmness
- **Collagen support** — patients looking to improve skin density and texture alongside retinoids or other actives
- **Post-procedure recovery** — after laser resurfacing, microneedling, or chemical peels where collagen remodeling is the goal
- **Hair thinning** — early-stage pattern hair loss, though the human data here are thin and the effect size relative to minoxidil is unclear

### Who should avoid it

- Anyone with a history of liver or kidney disease — copper is cleared via biliary and renal routes, and sustained exposure at high doses carries theoretical toxicity risk
- People with Wilson’s disease or other copper-metabolism disorders
- Anyone pregnant, breastfeeding, or planning a pregnancy in the near term — no controlled human data
- Patients considering injectable use — injectable GHK-Cu is on no FDA 503A list (FDA held it in Category 2 over safety concerns from 2023 to April 2026, and the nomination has since been withdrawn), and no large controlled human safety studies exist for that route

Timelines for topical GHK-Cu come from cosmetic practice rather than from trials, and they depend far more on the formulation than on the peptide: what matters is a delivery system that actually gets the molecule past the stratum corneum — liposomal formulations or microneedling are where the formulation science has moved.

## Route, dose and course

**Used for:** Skin, connective tissue and repair

**How it’s taken:** Topical serum, cream or eye product. Injectable GHK-Cu is on no FDA 503A list, so the compounding rules do not cover it.

**Doses sellers list:** Rx Peps Direct lists compounded topicals at 1% (scalp solution, 1 mL once daily) and 3% (creams and serums, once or twice daily), and an injection at 2 mg. Over-the-counter cosmetic serums rarely print a concentration, and no study or regulator sets a typical one. — No dose is approved for GHK-Cu. The figures are the seller's, not a recommendation; we searched the sellers' own pages so you don't have to. Where these figures come from: Rx Peps Direct peptide list (checked Oct 16, 2026)

**Cycle:** Continuous use rather than cycling — the effect is cumulative and reverses when you stop

**Legal status:** Not an FDA-approved drug. Topical cosmetic formulations are widely sold; the injectable is restricted.

**What it costs:** About $93 to $189 a month — From the sellers' own pages between November 4, 2026 and November 11, 2026; some sell it per vial or unit instead. Each figure, with what it leaves out, is in the table under “Can I actually get it?”. Over-the-counter cosmetic serums vary and rarely state the concentration.

GHK-Cu is prescribed as a topical formulation — serums, creams, or eye products. Over-the-counter cosmetic serums rarely print a concentration, and we found no study or regulator that sets a typical one; the compounded prescription creams we track are sold at 0.5% to 4%, by the sellers’ own pages. Injectable GHK-Cu is on no FDA 503A list, so the compounding rules do not cover it.

What sellers and studies publish (we checked on 16 October 2026):

- **What sellers publish (checked 16 October 2026):** [Rx Peps Direct](https://www.rxpepsdirect.com/peptides) lists compounded topicals at 1% (scalp solution, 1 mL once daily) and 3% (creams and serums, once or twice daily), and an injection at 2 mg
- **Stacking:** [Rx Peps Direct](https://www.rxpepsdirect.com/peptides) sells compounded creams and serums that pair it with niacinamide, estriol or SNAP-8

GHK-Cu is hydrophilic (logP below zero) and at roughly 340–402 Da it’s only nominally below the 500 Da rule for passive skin penetration, so how far it gets into the skin depends on the delivery system.

## No measured timeline

No human trial has measured how soon GHK-Cu works or how long any effect lasts, and we found no source we trust for a week-by-week picture, so we do not draw one. Agree with your prescriber what you will measure and when you will check it.

### Will it work where you live?

Most sellers claim all fifty states or publish nothing about coverage; a few name
 the states they serve or the ones they exclude, and the Coverage column says which.
 Either way it is the seller's own claim, so we can't filter this list by state
 without inventing a fact. What we can tell you is which state-level rules decide
 access: telehealth rules, non-resident pharmacy licensing, and who is allowed to
 prescribe.

## Questions we get about GHK-Cu

### Is GHK-Cu FDA-approved?

No — it's not an FDA-approved drug. Topical GHK-Cu is legal as a cosmetic ingredient (INCI name: Copper Tripeptide-1) and is available through compounding pharmacies under the FDA's 503A framework, where GHK-Cu for non-injectable routes sits in Category 1 (under evaluation) as of May 2026. The injectable-route nomination was withdrawn, so injectable GHK-Cu is on no 503A list and licensed US compounding pharmacies can't prepare it for injection.

### Is it legal?

For use on the skin, yes: as an over-the-counter cosmetic, or as a compounded cream with a prescription from a licensed clinician. Injectable GHK-Cu is not permitted under current FDA compounding rules. Buying it from gray-market "research chemical" sources is not legal and the quality is untested. We only feature providers and pharmacies with verifiable licensing. Availability can vary by state — confirm current access with the provider or your clinician.

### Are there side effects?

Topical GHK-Cu has a reasonable safety record across decades of cosmetic use. Occasional skin irritation or contact dermatitis at higher concentrations has been reported, typically from poorly formulated or pH-unstable preparations. Injectable use carries theoretical copper toxicity risk at sustained exposure; no large controlled human safety studies exist for that route.

### Can I take it with my current medications?

Topical use keeps systemic exposure low, which is the main reason interactions are rarely discussed — not because they have been studied and ruled out. Long-term human safety data is absent, and the FDA has raised copper-toxicity concerns about compounding it. If you're on medications that affect copper metabolism or have a history of liver or kidney disease, discuss with your provider before starting.

### How much does it cost?

In the price table on this page, monthly figures run from about $93 to $189, read on November 4, 2026. Some sellers price it per vial or unit instead, shown in the same table. It depends which GHK-Cu you mean. Cosmetic serums are sold over the counter at every price point and rarely state the concentration. Prescription versions are compounded creams, serums and injections, priced by the month or by the jar, and the table on this page says what each figure leaves out, such as consultation or annual review fees. On 8 October 2026 AgelessRx charged $99 (0.5%) or $149 (3%) for the first month of its cream and did not state the ongoing rate, so it is not in the table. Insurance does not cover these. Ask what concentration you are buying before you compare two numbers.

### Do I need a prescription for GHK-Cu?

Not for the cosmetic serums and creams sold over the counter, which list it as Copper Tripeptide-1. Yes for a compounded GHK-Cu cream: a licensed clinician writes the prescription, usually after an online intake with the telehealth seller, and a compounding pharmacy prepares it and ships it to you.

### How do I get GHK-Cu in the US?

For use on the skin there are two routes: an over-the-counter cosmetic product, or a compounded prescription cream through a telehealth seller, which means an intake form, a clinician's review and a pharmacy that ships the cream. Some sellers also offer injectable GHK-Cu. FDA's compounding rules do not cover that route: the injectable nomination was withdrawn, so it is on no 503A list, and FDA plans to take GHK-Cu to its compounding advisory committee before the end of February 2027.
