Educational summary. See Sources & research below for the underlying studies.
What it is
›
GHK-Cu is a copper peptide for skin, hair, and collagen that declines with age.
• Best for: skin quality, collagen, hair, and wound healing
• Forms: injectable for body-wide, topical for skin
• Edge: also antioxidant and tissue-remodeling
How it works
›
It carries copper and signals your skin to rebuild.
• Binds copper, a key skin-repair mineral
• Boosts collagen and tissue remodeling
• Adds antioxidant activity
Dosing and mixing
›
Reference tiers only. Track the dose you are already taking.
Low
1 mg/day or topical
FOR Skin maintenance or easing in
BENEFIT Often picked as the lower-exposure tier in skin and collagen discussions
Standard
1 to 2 mg/day
FOR Skin, hair, and anti-aging goals
BENEFIT The range most often cited in GHK-Cu discussions
High
2 mg or more/day, cycled
FOR Faster skin or wound results
BENEFIT A higher-exposure tier for which copper intake monitoring is commonly discussed
Schedule: Daily subcutaneous, or topical for skin. Cycle if high.
Beginner ramp: Start low, topical is gentlest for the face.
Mixing (reconstitution)
BAC water is bacteriostatic water, the sterile water you mix in.
A 50 mg vial with 5 mL BAC water is a common starting point.

›
Weeks 1 to 2
Subtle, skin is just starting to remodel.
Weeks 3 to 6
Skin smoothness and tone improve for many.
Weeks 6 to 12
Main window for skin, hair, and collagen.

Very high doses can affect copper balance, do not overdo it.
Side effects
›
Commonly reported
• Injection-site irritation
• Temporary skin redness with topical use
See a clinician if
• Signs of copper excess with very high use
Storage
›
Keep it cold and dark.
• Refrigerate after reconstitution
• Protect from light
• Do not freeze
Common stacks
›
• GHK-Cu + BPC-157: people pair these when both skin and tissue-recovery research are relevant
• GHK-Cu + collagen support: people pair these when interested in complementary skin approaches
