This blend pairs GHK-Cu — a naturally occurring copper-binding tripeptide with a developed literature in wound healing and collagen — with Epithalon, a synthetic tetrapeptide studied in relation to telomerase and circadian function.

The two come from quite different research bases: GHK-Cu from tissue-repair and dermatology work, Epithalon from a smaller and largely preclinical Russian literature. Neither is FDA-approved.

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 / Epithalon come up?

GHK-Cu has the stronger evidence base of the two, with published work in wound repair and collagen synthesis. Epithalon's literature is early and largely preclinical. Combining them is a compounding choice, not something the published evidence addresses.

✔A provider decides, not a quiz

Every GHK-Cu / Epithalon 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 / Epithalon 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 / Epithalon 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 / Epithalon 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.

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

A provider licensed in your state reviews your answers online — no appointment, no waiting room. They decide whether GHK-Cu / Epithalon 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 / Epithalon for?

It's for adults who want GHK-Cu / Epithalon 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, repair and longevity

GHK-Cu is studied in tissue repair; Epithalon in the longevity category.

✔You want a real prescription

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

✔You want the dosing decided for you

Vial contents are fixed; amount and schedule are set by your prescriber.

✔You prefer one vial to two

Both peptides are compounded together as a single injection.

✕When it's not the right fit

Neither component is FDA-approved and the blend has not been studied as a combination. Compounded drugs are not FDA-reviewed 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.

How to get it

How do I get GHK-Cu / Epithalon online?

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

Using it & safety

How is it taken, and is it safe?

GHK-Cu / Epithalon is compounded as injection. The amount and the schedule are set by the provider who reviews your 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

Neither component is FDA-approved and the blend has not been studied as a combination. Compounded drugs are not FDA-reviewed 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
  • Temporary blue-green discolouration of the skin (copper)
  • Drowsiness
  • 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 / Epithalon FAQ

What is in this blend?

GHK-Cu, a copper-binding tripeptide, together with Epithalon, a synthetic tetrapeptide. The milligrams of each are shown on the strength selector.

Why is the liquid blue-green?

That is the copper in GHK-Cu. It is expected and is not a sign of contamination.

Which component has better evidence?

GHK-Cu, clearly. It has published work in wound healing and collagen synthesis. The Epithalon literature is early and largely preclinical.

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.
