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 review by a licensed provider of 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.

	Oral supplement	"Research only" vial	Prescribed GHK-Cu (Rx)
What it is	An unregulated oral precursor	A vial sold without a prescription	Compounded GHK-Cu dispensed on a provider's order
Licensed provider reviews you	No	No	Yes — before anything is dispensed
Compounded by a licensed pharmacy	No	No	Yes — U.S. 503A
Your name on the vial	No	No	Yes
Dose set by a prescriber	No	No	Yes
Legal to sell for human use	As a supplement	No	Yes — by prescription

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, a licensed provider reviews them, and if they prescribe, a 503A pharmacy compounds and ships it.

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.

Meet your provider live

A provider licensed in your state reviews your answers online — no appointment, no waiting room. They decide whether GHK-Cu is appropriate.

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 reviews your visit.

✔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 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 in your answers. New or unexplained symptoms should be evaluated by a clinician rather than self-treated.

Safety & side effects

⚠ Not FDA-approved for any condition

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.

Questions, answered

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 who reviews your 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. You complete the questionnaire online and a licensed provider reviews it — there is no scheduling step and no waiting room.

Can I order more than one peptide?

Yes. Add each one to your cart and check out once. A provider reviews every treatment in your order.
