once daily · SubQ (or topical)
Half-life
~1–2 hours
What is GHK-Cu (Copper Peptide)?
Tripeptide copper complex found naturally in human plasma. Powerful anti-aging and regenerative effects.
How GHK-Cu (Copper Peptide) works
Binds copper ions and delivers them to tissue repair sites, activating collagen synthesis, antioxidant enzymes (SOD), and anti-inflammatory cytokine pathways.
Benefits & uses
- Collagen synthesis
- Skin remodeling
- Wound healing
- Anti-aging
- Hair growth
Common uses: Skin regeneration, wound healing, anti-aging, collagen synthesis, hair growth.
GHK-Cu (Copper Peptide) dosage
- Typical dose
- Typical: 1–2 mg/day SubQ (injectable); topical use is separate. 4–8 weeks.
- Protocol notes
- 1-3mg per injection, 3-5x per week. Topical: apply to skin directly.
GHK-Cu (Copper Peptide) half-life
~1–2 hours (plasma), longer tissue effects
GHK-Cu (Copper Peptide) side effects
Very safe. Topical or SubQ injection both used.
- Mild injection site redness (transient)
- Copper-taste reaction in some users
- Topical form very well tolerated; injection form generally safe
Warnings & monitoring
- Research use only
Preparation & storage
- Preparation
- Mix a 50 mg vial with 5 mL bac water → 10 mg/mL. A 2 mg dose = 0.2 mL = 20 units.
- Reconstitution
- Reconstitute a 50 mg vial with 5 mL BAC water → 10 mg/mL. A 2 mg dose = 0.2 mL = 20 units on a U-100 syringe.
- Storage
- Lyophilized: room temperature or refrigerated. Reconstituted: refrigerate (2–8 °C), use within 30 days.
GHK-Cu (Copper Peptide) interactions
with BPC-157
CompatibleBoth peptides promote collagen synthesis and wound healing through non-overlapping mechanisms, making this a potent tissue-repair stack.
Timing: Administer at the same time or within the same injection window
with BPC-157
CompatibleComplementary healing peptides. BPC-157 promotes tissue repair and gut healing; GHK-Cu stimulates collagen synthesis and wound healing. Synergistic effects for recovery.
Timing: Can be administered together or separately; subcutaneous or intramuscular
with Epithalon
CompatibleEpithalon's telomerase-elongation pairs well with GHK-Cu's gene-resetting copper-tripeptide activity — a longevity duo with non-overlapping mechanisms.
Timing: Run as concurrent 10–20 day pulses, 2–4× per year
with Epithalon
CompatibleGHK-Cu promotes tissue remodeling and collagen while Epithalon provides anti-aging effects via telomere extension — a well-tolerated anti-aging peptide stack.
Timing: Administer in separate SubQ injections; can be same-day or alternating protocol
with TB-500
CompatibleComplementary collagen and wound-healing peptides. GHK-Cu activates copper-dependent healing pathways; TB-500 promotes cell migration and angiogenesis. Excellent for skin, joint, and tissue repair.
Timing: Combine in the same injection or separate; both subcutaneous
with TB-500
CompatibleComplementary healing and collagen synthesis peptides. TB-500 accelerates cell migration; GHK-Cu activates copper-dependent tissue repair enzymes. Synergistic for skin, tendons, and joints.
Timing: Combine in the same injection or administer separately; both subcutaneous
with TB-500
CompatibleTB-500 accelerates cellular migration and angiogenesis while GHK-Cu drives collagen production and skin repair — complementary healing peptides with no known adverse interaction.
Timing: Can be combined in the same syringe or injected at the same time
