Peptide protocols · GHK-Cu
GHK-Cu — copper peptide for remodeling.
A naturally-occurring copper-binding tripeptide with research support for skin remodeling, collagen synthesis, hair restoration adjunct, and wound healing. Long history of use in dermatology and cosmetics; clinical use through compounding pharmacies has grown alongside the longevity-medicine movement.
What it is
GHK-Cu is a tripeptide (glycine-histidine-lysine) bound to a copper ion. The human body produces it naturally; levels decline with age. Research supports roles in tissue remodeling, wound healing, collagen and elastin synthesis, and antioxidant activity.
How it works
GHK-Cu activates a number of remodeling pathways: stimulates fibroblast proliferation and collagen synthesis, modulates MMP/TIMP balance for extracellular matrix remodeling, accelerates wound healing through angiogenesis and reduced inflammation, and exhibits direct antioxidant activity.
Who it's for
GHK-Cu makes clinical sense for:
- Skin quality optimization (collagen, elastin support)
- Hair restoration adjunct (often paired with finasteride/minoxidil)
- Wound healing and post-procedure recovery
- Anti-aging protocols emphasizing extracellular matrix health
Dosing and cadence
Injectable: 1–3mg subcutaneous daily. Topical: applied to skin or scalp 1–2 times daily. Many patients use both — injectable for systemic effect, topical for site-specific concerns.
What to expect
Skin texture and tone improvements typically noticeable at 4–8 weeks. Hair-quality changes (in patients using it as adjunct) take 12+ weeks. Wound-healing applications show faster response.
How Vektor handles it
Vektor prescribes GHK-Cu in injectable form (10mg/mL in 5mL vial) through our 503A pharmacy partner. Topical compounds available for site-specific use.

Frequently asked
- Is GHK-Cu safe for daily use?
- Yes, when prescribed at standard clinical doses. Copper toxicity is theoretically possible at very high doses but unlikely at typical protocol levels. Patients with Wilson's disease (copper-handling disorder) should avoid.
- Can GHK-Cu replace finasteride for hair loss?
- No. Finasteride blocks DHT, the primary driver of male-pattern hair loss. GHK-Cu supports follicular environment and extracellular matrix health. They work on different mechanisms and are often used together.
