← All peptidesGHK-Cu
The copper tripeptide that resets 4,000+ genes to a younger pattern — repair, not just skin.
📊 The Protocol
Reconstitute2 mL BAC water (use 'No-Sting' — it stings otherwise)
DoseAesthetics: 0.5–1 mg · Injury/internal: 2.5–5 mg
Frequency3–5×/wk
TimingPM, fasted (collagen synthesis peaks at night)
Cycle12 wks on / 4 off
💪 What it does
It doesn't build new skin — it does a biological reset on the skin you have, clearing damaged collagen, wrinkles, and scars while rebuilding the micro blood-vessel plumbing (VEGF) that feeds starving cells. Systemically it spikes cellular ATP and calms inflammation better than cortisone.
🔬 How it works
A copper tripeptide your body makes naturally (drops ~60% from age 20→60) that flips the switch on 4,000+ genes and hands bioavailable copper to mitochondrial Complex 4 — the rate-limiting step of ATP production.
💡 Pro tips
2 mg/day is a 'gross overdose' for aesthetics — run 1 mg (even that's high) + 25–50 mg zinc/day, or GHK dumps your zinc and you get the 'copper uglies.' 500 mcg outperforms 2 mg for most. 🧪
It repairs, it doesn't build — supply the raw materials: collagen + vitamin C + hyaluronic acid AM, GHK at night. NEVER run topical vitamin C with topical GHK (they cancel). 🧪
NEVER blend GHK-Cu in one vial with BPC-157 / TB-500 — it chelates copper and causes receptor competition; inject each separately. 🩺
It's not a skin peptide — the skin stuff is downstream of a mitochondrial reset (+67% ATP). 🩺
