GHK-Cu

Skin and tissue support at the peptide level

About GHK-Cu

GHK-Cu (GHK-Copper) is a naturally occurring copper-binding tripeptide first identified in human plasma in the 1970s. It is studied for its role in skin remodeling, wound signaling, and connective tissue support. Levels of GHK-Cu decline with age, which is part of why it has become a focus of skin and recovery research. At PreventiveMD it is offered as a topical compounded preparation as part of a broader skin and recovery plan.

Common reasons patients ask about GHK-Cu:

  • Studied for support of skin firmness, elasticity, and tone
  • May support skin barrier and how skin responds to environmental stress
  • Researched alongside hair and connective-tissue health
  • Used as part of a broader skin and recovery routine

Data

What the studies show

Most of the published research on GHK-Cu comes from in vitro experiments, animal models, and small clinical studies in cosmetic dermatology; large randomized human trials are limited. The available evidence suggests it may support skin appearance and tissue signaling, but enthusiasm should be weighed against the limits of the evidence base. Compounded peptides are not FDA-approved as finished drugs.

How it works

Signals activity in skin and connective tissue

GHK-Cu is best understood as a signaling peptide. It binds copper — a mineral the body uses in dozens of repair enzymes — and helps deliver it where it is needed. In laboratory and small clinical studies, GHK-Cu has been associated with changes in genes involved in tissue remodeling, antioxidant defense, and how skin responds to damage.

Eligibility

Who GHK-Cu is for

Generally a good fit for

  • Adults interested in skin appearance, firmness, or tone
  • Patients building a structured skin and recovery routine
  • People comfortable with treatments where the evidence base is still developing

Not appropriate for

  • Pregnancy, planning pregnancy, or breastfeeding without provider guidance
  • Known copper sensitivity or Wilson's disease
  • Active skin infection, severe eczema, or open wounds at the application site
  • Known allergy to GHK-Cu or any inactive ingredient in the preparation

Journey

What to expect & when

  1. Weeks 1–4

    • Most changes are subtle and gradual
    • Some patients report improved skin feel or hydration

  2. Weeks 5+

    • Possible incremental changes in firmness, tone, or texture with consistent use
    • Effects are personal and depend on skin type and routine

  3. Ongoing

    • Continued monitoring, dose adjustments, and cycling decisions guided by your PreventiveMD provider

Side effects

Safety & side effects

Topical GHK-Cu is generally well tolerated. As with any topical peptide preparation, watch for skin reactions early and discontinue if irritation develops.

Common

  • Mild redness or warmth at the application site
  • Temporary tingling or itching
  • Dryness or flaking, especially when combined with active skincare

Less common but serious

  • Allergic contact dermatitis
  • Worsening of underlying skin conditions
  • Rare systemic reaction in patients with copper sensitivity

If you have questions about whether GHK-Cu is right for you, your PreventiveMD provider will review your full health history once you get started.

Dosing

How to take GHK-Cu

  • Typically a pea-sized amount applied once or twice daily to clean skin, as directed by your provider. Specific dose is set by your provider based on goals and tolerance.

    How to apply

    1. 1Cleanse the area gently and pat dry before applying.
    2. 2Apply a thin, even layer of the cream to the target area.
    3. 3Allow it to absorb before layering other actives or sunscreen.
    4. 4Wash your hands after application and avoid the eye area.

FAQs

In case you were wondering

No. Many cosmetic products list 'copper peptides' on their labels, but concentrations and quality vary widely. Compounded GHK-Cu prescribed by a clinician is typically standardized and dosed more deliberately.

For our compounded medications, yes every dose is the same price, and no, there are no hidden fees. Our pricing is based on your plan length, never your dose, and is designed to be simple and not gimmicky.

Whether you’re on a starting dose or a higher maintenance dose, your price stays the same, and it’s all-inclusive: provider review, medication, supplies, shipping, and ongoing support. There are no membership, consultation, or cancellation fees.

Longer plans come at a lower monthly rate and are paid upfront, and you can always see current pricing for every medication and plan on our site.

Often yes, but layering depends on your skin and the rest of your routine. Your provider can help you sequence products to avoid irritation.

Most patients describe gradual changes over several weeks. GHK-Cu is best thought of as a long-term skin support, not a fast cosmetic fix.

No. Currently, labs aren't required to get started. Your provider will review your medical questionnaire responses to confirm if the medication is appropriate for you.

Compounded GHK-Cu preparations are not FDA-approved as finished drug products. They are prepared under physician supervision for individual patients, which is a different regulatory pathway than prescription drugs you'd find at a retail pharmacy.
