Topical copper peptide for wound repair
Compare GHK-Cu (Topical) with other peptides →Summary
A copper peptide that helps cuts heal faster and fade scars.
- Typical dose
- 1-3% concentration 1-2x daily on clean wound
- Route
- Topical
- Cycle length
- Until healed
- Evidence
- Limited human data
Mechanism
How it works
GHK-Cu works like a wound repair kit — it delivers copper tools needed for healing while calling in fibroblast construction crews.
GHK-Cu delivers copper to wound healing enzymes, activates fibroblasts, reduces inflammation, and promotes organized collagen deposition.

In depth
Full profile
What it does
Cuts close faster, scars are smaller, and skin gets stronger.
How it works
GHK-Cu is like a wound repair kit. It brings copper tools for healing and calls in tiny builder cells to fix the skin.
It grabs onto copper-using helpers in your body. It turns on over 4,000 genes that help skin heal.
What to expect
You can see your wound healing better in 3-7 days.
- Days 2-3: Less swelling and pain.
- Days 5-7: The cut closes up faster.
- Weeks 2-4: Smaller scars.
Good to know
- Test a small spot of skin first
- Clean the wound well before you put it on
Staying safe
- A little sting when you put it on
- Some redness for a short time
Avoid if you have:
- People with Wilson's disease (too much copper in the body)
- People who react badly to copper
- Open wounds that have an infection
Mechanism of action
GHK-Cu delivers copper to wound healing enzymes, activates fibroblasts, reduces inflammation, and promotes organized collagen deposition.
Binds to copper-dependent enzymes (lysyl oxidase) and modulates over 4,000 genes involved in repair.
Pharmacodynamics
Visible wound healing improvement within 3-7 days.
Faster wound closure, less scarring, improved tissue strength.
Timeline
- Days 2-3: Reduced inflammation and pain.
- Days 5-7: Accelerated wound closure.
- Weeks 2-4: Reduced scar formation.

Qué hace
Los cortes se cierran más rápido, las cicatrices son más pequeñas y la piel se fortalece.
Cómo funciona
GHK-Cu es como un kit de reparación de heridas. Trae herramientas de cobre para la curación y llama a pequeñas células constructoras para reparar la piel.
Se une a los ayudantes que usan cobre en tu cuerpo. Activa más de 4.000 genes que ayudan a que la piel sane.
Qué esperar
Podrás notar una mejor cicatrización en 3-7 días.
- Días 2-3: Menos inflamación y dolor.
- Días 5-7: El corte se cierra más rápido.
- Semanas 2-4: Cicatrices más pequeñas.
Bueno saber
- Prueba una pequeña zona de la piel primero
- Limpia bien la herida antes de aplicarlo
Manteniéndose seguro
- Un ligero ardor al aplicarlo
- Un poco de enrojecimiento por un tiempo corto
Evitar si tienes:
- Personas con enfermedad de Wilson (demasiado cobre en el cuerpo)
- Personas que reaccionan mal al cobre
- Heridas abiertas infectadas
Mecanismo de acción
GHK-Cu entrega cobre a las enzimas de reparación de heridas, activa los fibroblastos, reduce la inflamación y promueve la deposición organizada de colágeno.
Se une a enzimas dependientes de cobre (lisil oxidasa) y modula más de 4.000 genes involucrados en la reparación.
Farmacodinamia
Mejora visible en la cicatrización de heridas en 3-7 días.
Cierre más rápido de heridas, menor formación de cicatrices, mayor resistencia del tejido.
Cronología
- Días 2-3: Reducción de la inflamación y el dolor.
- Días 5-7: Cierre acelerado de la herida.
- Semanas 2-4: Reducción de la formación de cicatrices.
