GHK-Cu is a tripeptide — glycyl-L-histidyl-L-lysine — that binds copper and occurs naturally in human plasma, where its concentration is known to fall with age. It is one of the better-studied peptides in this catalogue, with published work in wound healing, collagen and skin remodelling.

It is compounded here in two forms: a subcutaneous injection and a topical cream at 1.5% or 3%. Which form you receive is part of the prescription written by the provider who sees you.

This is a compounded preparation, not an FDA-approved medication, and compounded drugs are not reviewed by the FDA for safety or effectiveness. Individual results are not guaranteed. It is prescribed only where a licensed provider determines it is appropriate after reviewing your health history.

Why people ask about it

Why does GHK-Cu come up?

GHK-Cu appears widely in skin and hair formulations because of laboratory and clinical work on copper peptides in wound repair and collagen synthesis. That literature is more developed than for most peptides here, but a compounded GHK-Cu preparation is still not an FDA-approved medication for any indication.

✔A provider decides, not a quiz

Every GHK-Cu prescription here follows a live consultation with a licensed provider who sees your health history, current medications and goals. If it isn't appropriate for you, it isn't prescribed.

✔Compounded, not a research chemical

Your vial is compounded by a licensed U.S. 503A pharmacy and dispensed against a prescription written in your name — not sold as a "research only" product with no oversight.

Know the difference

Prescribed GHK-Cu vs. supplements and grey-market vials — what's the difference?

The short answer: unregulated supplements make claims nobody checks, "research only" vials sold online carry no prescription, no pharmacy and no accountability, and a prescribed GHK-Cu is compounded by a licensed 503A pharmacy against a provider's order written for you.

The simplest test of any peptide seller: is your name on the vial? A "research only" label means no prescriber reviewed you, no licensed pharmacy compounded it, and nobody is accountable for what is actually inside.

How it works

How does getting GHK-Cu actually work?

Three steps: answer a short set of medical questions, connect straight to a licensed provider on a live video call, and if they prescribe, a 503A pharmacy compounds and ships it.

I

Answer a few questions

A short private medical questionnaire — your history, current medications and what you are hoping to address. It takes a couple of minutes.

II

Meet your provider live

You go straight onto a video call with a provider licensed in your state — no appointment, no waiting room. They review your answers with you and decide whether GHK-Cu is appropriate.

III

Compounded & shipped

If they prescribe, a licensed U.S. 503A pharmacy compounds your vial and ships it discreetly, with your name on the label.

Who it's for

Who is GHK-Cu for?

It's for adults who want GHK-Cu prescribed and compounded properly rather than bought from a grey market. Whether it is appropriate for you is a decision for the provider who sees you on the call.

✔Interested in skin, hair and repair

GHK-Cu is studied in the context of collagen, skin remodelling and tissue repair.

✔You want a real prescription

Reviewed on a live call by a licensed provider, compounded by a 503A pharmacy, dispensed with your name on the label.

✔You would rather not inject

GHK-Cu is one of the few peptides here compounded as a topical cream as well as an injection.

✔You want the dosing decided for you

Strength and application are set by your prescriber, not chosen from a menu.

✕When it's not the right fit

Compounded GHK-Cu is not an FDA-approved medication and has not been shown to treat, cure or prevent any disease. Compounded drugs are not reviewed by the FDA for safety or effectiveness. Individual results are not guaranteed. If you are pregnant or breastfeeding, have an active cancer diagnosis, or have significant kidney or liver disease, tell your provider on the call. New or unexplained symptoms should be evaluated by a clinician rather than self-treated.

How to get it

How do I get GHK-Cu online?

You answer a few questions, meet a licensed provider on a live video call, and — if they prescribe — your medication is compounded and shipped to your door. No insurance required, no in-person appointment, no waiting room.

A few questions

Using it & safety

How is it taken, and is it safe?

GHK-Cu is compounded as injection · cream. The amount and the schedule are set by the provider on your video visit — we deliberately do not publish a dosing regimen here, because that is a clinical decision about you, not a product specification.

Safety & side effects

⚠ Not FDA-approved for any condition

Compounded GHK-Cu is not an FDA-approved medication and has not been shown to treat, cure or prevent any disease. Compounded drugs are not reviewed by the FDA for safety or effectiveness. Individual results are not guaranteed.

Reported effects are most often related to the injection itself or to infusing too quickly. They can include:

  • Redness, soreness or swelling at the injection site
  • Local irritation or stinging with the topical cream
  • Temporary blue-green discolouration of the skin (copper)
  • Headache

Tell your provider about every condition and medication before starting, including pregnancy or breastfeeding. Stop and seek care for signs of an allergic reaction — rash, swelling of the face or throat, or difficulty breathing. For emergencies call 911.

GHK-Cu FAQ

What is GHK-Cu?

GHK-Cu is a copper-binding tripeptide (glycyl-L-histidyl-L-lysine) that occurs naturally in human plasma. Its concentration is known to decline with age, and it has been studied in wound healing, collagen synthesis and skin remodelling.

Injection or cream — which will I get?

Both are compounded. The injection is supplied as a 50mg vial and the cream at 1.5% or 3%. Which form is appropriate for you is decided by the provider on your video visit.

Why does copper matter?

GHK binds copper, and the copper complex is the form studied in the tissue-repair literature. The blue-green colour of the preparation comes from the copper.

Do I have to book an appointment?

No. After the questionnaire you are connected to an available provider on a video call, usually within seconds — there is no scheduling step and no waiting room.

Why can I only order one peptide at a time?

Every peptide requires its own provider consultation, so each one is its own visit. Complete this visit and you can return to the peptide shop to start another.
