GHK CU
- A copper tripeptide that conditions the scalp
- It is not an antiandrogen and does nothing to DHT
- Every batch tested by an independent lab before it ships
- A support layer — it will not hold a hairline on its own
We formulate it, we blend it in the EU, and an independent laboratory tests every batch before it ships. Questions before you start? Write to us — we answer first, you buy second.
What is GHK-Cu?
GHK-Cu is a copper tripeptide — a small copper-carrying peptide used mainly in skin and wound-healing research. We supply it as a labelled scalp spray, blended by us in the EU, with the batch number and blend date on every bottle. It is a support product, not a hair-loss drug.
How it works — and what it does not do
GHK-Cu works on the condition of the scalp itself: the skin your follicles sit in. It is not an antiandrogen. It does nothing to DHT, the enzyme that makes it, or the receptor it binds — so it does not address the cause of male-pattern hair loss at all. On its own it will not hold a receding hairline, and we won’t suggest otherwise.
What the evidence actually is
Be clear-eyed here. Most of the research on GHK-Cu is about skin and wound healing; the evidence in hair specifically is thin. It is included in the range as scalp support alongside a blocker, not as a treatment that regrows hair by itself.
How to use it
Six to seven pumps of the spray is about 1 ml. Apply to a dry, clean scalp over the areas you are treating, once a day, and let it dry.
Where it fits
GHK-Cu is a support layer. It pairs with a receptor blocker like RU-58841 or pyrilutamide — the blocker addresses the cause, GHK-Cu looks after the scalp. Used alone, it is the mildest thing you can do.
Suitability & safety
For topical, research use. Copper peptides are generally well tolerated on skin; patch-test first and stop if you react. Speak to a professional if unsure.
Batch & storage
Every bottle is stamped with its batch number, blend date and expiry. Store it cool, dry and out of direct light.
A copper peptide that works on the condition of the scalp itself. Not an antiandrogen; it does nothing to DHT.
Each compound does one job.
Nothing in this range replaces anything else in it. Each one acts at a different point in the same problem. What it does, and what it leaves untouched, is written on the card.
RU58841 5/8% 50/100ml
Occupies the androgen receptor so DHT cannot deliver its signal to the follicle.
This is the cause, not the symptom. On its own it will not push a dormant follicle back into growth.
Pyrilutamide 0.5%
A newer topical androgen-receptor antagonist. Different molecule, same target as RU-58841.
For people who do not tolerate RU. Run one blocker or the other, not both.
Natural Hair Regrow Formula
Caffeine, rosemary and botanical oils. Scalp support, and the mildest thing in the range.
A leg of the routine, not the whole table. It does not block DHT.
It works on the scalp — not on the hormone.
Most of this site is about blocking DHT, the hormone behind male-pattern hair loss. GHK-Cu does not do that. It is worth being precise about what a copper peptide is for, and what it is not.
- 01
A copper-carrying peptide
GHK-Cu is a small tripeptide bound to copper. In skin research it is associated with the condition and repair of the tissue it sits in. Here, that tissue is your scalp.
- 02
It conditions the skin your follicles grow from
A follicle grows out of scalp skin. GHK-Cu is used to support the quality of that skin — the environment around the follicle, rather than the follicle’s hormonal signal.
- 03
It does not touch DHT
This is the honest part. GHK-Cu is not an antiandrogen. It does nothing to DHT, the enzyme that makes it, or the receptor it binds. The cause of pattern hair loss runs on untouched. This is support, not a brake.
- 04
Which is why it is a layer, not the base
On its own, GHK-Cu will not hold a receding hairline. Its place is alongside a blocker that addresses the cause — looking after the scalp while the real work happens elsewhere.
Where the evidence stands
We would rather you knew this than found out later. The bulk of GHK-Cu research is in skin and wound healing; the hair-specific evidence is thin. We include it as scalp support, not as a regrowth treatment.
Who it is for
GHK-Cu makes most sense if your scalp condition is part of the picture and you are already running a blocker for the cause. If you are looking for the one thing to stop a receding hairline, this is not it — a receptor blocker is.
What we can be held to
We won’t dress GHK-Cu up as more than it is. What we can stand behind is the bottle: a copper peptide blended by us in the EU, lab-tested every batch, dated so you know how fresh it is.
A spray, once a day.
GHK-Cu comes as a scalp spray pump. Simple to apply; best used as part of a routine rather than on its own.
-
01
Count the pumps
Six to seven pumps of the spray is roughly 1 ml. It is a spray pump, so you count it — there is nothing to measure.
-
02
Apply to a clean, dry scalp
Spray over the areas you are treating, onto the skin. A clean scalp takes it best.
-
03
Let it dry
Spread it gently and let it dry. Nothing to wash out.
-
04
Pair it, don’t rely on it
GHK-Cu is a support layer. Use it alongside a blocker, at the same time each day, and judge the routine as a whole.
For topical, research use. Batch number, blend date and expiry are printed on the bottle.
Set your expectations honestly.
GHK-Cu is scalp support, not a regrowth drug. What follows is what is reasonable to expect from a copper peptide — no more.
-
WEEKS 0–4
Getting into the routine
Take photographs of your scalp condition, not just your hairline. Early on there is nothing dramatic to see — that is normal for a support product.
-
MONTHS 1–2
Scalp condition
Any change here is about the state of the skin — comfort, condition — rather than new hair. If regrowth is your goal, that job belongs to the blocker you pair this with.
-
MONTHS 3+
As part of the whole
Judge GHK-Cu as one layer of a routine, not on its own. On its own, a copper peptide will not reverse a receding hairline.
-
ONGOING
Its honest place in the plan
Keep GHK-Cu for scalp support and let a receptor blocker do the work on the cause. That division of labour is the whole point of the range.

Folliva Labs repliedFair enough. Its really meant as an add on for scalp condition, not a standalone. Best used next to your main treatment. Thanks for the honest one.

A comparison of mechanisms, not medical advice. Minoxidil and finasteride are approved medicines with decades of randomised trials behind them, and finasteride has the largest measured effect of anything here. RU-58841 is a research compound: no approved human use, no completed human trials, and therefore no side-effect rates to quote for it — only the way it was designed. The natural column covers topical caffeine, rosemary oil and saw palmetto, where the human data is real but thin. Prices are rough monthly estimates and vary by dose and brand. Speak to a doctor before you start or stop anything.
We won’t oversell a copper peptide. Here is exactly what it is.
GHK-Cu is a copper tripeptide that supports the condition of your scalp. It is not an antiandrogen, it does nothing to DHT, and on its own it will not hold a receding hairline — the blocker in your routine does that. If scalp support is what you are after, this is it: blended by us in the EU and lab-tested every batch.
- Every batch is tested by an independent laboratory before it ships.
- Formulated and blended by us in the EU.
- Batch, blend date and expiry printed on every bottle. It degrades with time, so its age matters.
- Plain, unbranded packaging. Nothing on the outside says what is inside.
Questions, answered.
What is GHK-Cu?
A copper tripeptide — a small copper-carrying peptide used mainly in skin and wound-healing research. We supply it as a scalp spray for supporting scalp condition.
Does it block DHT?
No. GHK-Cu is not an antiandrogen and does nothing to DHT, the enzyme that makes it, or the receptor it binds. It works on the condition of the scalp, not on the hormone behind pattern hair loss. It does not address the cause of hair loss on its own.
Will it regrow my hair?
Not by itself, and we won’t pretend it will. The hair-specific evidence for GHK-Cu is thin — most of the research is in skin and wound healing. Its job is scalp support alongside a receptor blocker that does the actual work on the cause.
How do I use it?
Six to seven pumps of the spray is about 1 ml. Apply to a clean, dry scalp once a day and let it dry. It is a spray pump, so you count it; there is nothing to measure.
What should I pair it with?
A receptor blocker — RU-58841 or pyrilutamide — addresses the cause of the loss. GHK-Cu looks after the scalp while that happens. Used alone, it is the mildest thing in the range.
Are there side effects?
Copper peptides are generally well tolerated on skin. Patch-test first and stop if you react. It is a topical, so it does not carry the systemic effects of oral drugs.
How do I know it is genuine?
We blend it in the EU and an independent laboratory tests every batch before it ships. Every bottle carries its batch number, blend date and expiry.
Shipping and returns?
Shipped from the EU, usually 2–5 working days, in plain unbranded packaging. Unopened bottles can be returned within 14 days.
