Lab resultsGHK-Cu, explained
GHK-Cu is a copper-binding peptide studied in skin cells, collagen production and topical skin care.
What it’s used for
Skin appearance
A small topical post-laser study found greater satisfaction, without clear improvement on measured skin outcomes.
Hair and brow growth
A small controlled study of a 2% serum reported more eyebrow hairs and greater thickness over 12 weeks.
Wound and tissue repair
Cell and animal work explores wound healing, inflammation and new blood-vessel growth.
What to expect
- Weeks 1–4
Hydration and texture changes reported
- Weeks 4–8 · hair
Hair changes reported with injections
- Weeks 6–12
Firmness and tone changes reported
Side effects & safety
Side effects
- Stinging at the injection site, reported by users
- Skin sensitivity, burning, redness or discoloration with topical use
- Injection risks include extra copper exposure, infection and staining
Stop and get help if
- Signs of an allergic reaction
- Severe irritation or discoloration that doesn't go away, or skin getting worse
- Signs of infection or tissue damage at the injection site
- Nausea, metallic taste or unusual fatigue
What regs say
- The FDA has flagged immune-reaction risks from aggregation and impurities in injectable GHK-Cu.
Avoid or check first
- Applying near the eyes or on mucous membranes
- Taking copper supplements — adds to total copper exposure
In sport
- The reference reports no settled WADA ruling for injectable GHK-Cu; cosmetic GHK guidance does not settle every formulation.

How to mix and store it
How many units do I draw?
How to mix5 steps
Wipe both tops
Wash your hands, then swab both rubber vial tops with alcohol. Let them dry.
Draw the water
Use a new sterile syringe to draw the water volume selected in the calculator.
Run it down the wall
Introduce the water slowly down the inside glass wall, rather than directly onto the powder.
Swirl, don’t shake
Gently swirl or roll the vial. Allow time for the powder to dissolve.
Label the vial
Write the preparation date and the amount and final volume on the vial label.
Injecting under the skinWhere, rotating sites, which syringe
Where
Subcutaneous injections go into the fatty layer beneath the skin. Common sites include the abdomen, outer thigh and upper arm. Keep at least 5 cm from the navel and avoid bruised, irritated or damaged skin.
Rotate sites
Change the spot each time. Clean the skin and let it dry.
Single-use equipment
Use a new sterile needle and syringe each time. Place used needles in a sharps container.
Storage
Storage
Refrigerated at 2–8°C. Reported period: 30 days.
Combining it with others
Don’t combine
Use caution
- Vitamin C serums
Acidic skin-care products may break down copper peptides.
- AHK-Cu
The total copper exposure depends on the product and how it is used.
Other combinations

- SNAP-8
They target different skin effects. Product compatibility has not been verified.
Often taken together
- Wolverine Stack
GLOW adds GHK-Cu to the Wolverine ingredients.
- BPC-157
Studied for similar tissue-repair uses and included together in some blends.
- TB-500
Studied for similar tissue-repair uses and included together in some blends.
What the research says
Copper and collagen
GHK binds copper. Cell studies measured collagen production in fibroblasts, the cells that build supporting tissue.
What studies found
Collagen in cells
Cell study · 1988In 1988, lab-grown fibroblasts, the cells that build supporting tissue, produced more collagen after GHK-Cu exposure.
Topical skin-care trial
Topical study · 13 people · 12 weeksAt 12 weeks, 13 people had completed the skin-care comparison. Redness, wrinkles and overall skin-quality measures showed no clear group difference. People using GHK-Cu reported greater satisfaction.
How long it stays in your body
Half-life is the time it takes for the amount in the body to fall by half. It does not tell you how long effects last.

Molecular notes
Copper complexes of glycyl-L-histidyl-L-lysine. Primary chemistry experiments found multiple complex stoichiometries. A single formula or mass is not assigned without specifying the chemical species; pills and finished serums remain separate.

Questions
What does 50mg mean?
It describes an amount of material in the unit stated on the label. It does not describe liquid volume, a dose, or how to prepare the product.
Read more about amountsDoes purity mean it is sterile?
No. Purity and sterility require different tests. An endotoxin result also does not establish sterility.
About testingCan I calculate concentration?
You need a mass in mg and either a final volume or a target concentration. IU and blends require separate, verified information.
