Dosing Guide — 2026-11-10
GHK-Cu (copper tripeptide-1) is one of the most-studied peptides for skin, collagen, and tissue-remodeling research. This guide gives the exact reconstitution and daily-dose units for both the GHK-Cu 50mg and 100mg vials, plus cycle length, vial longevity, and the standard zinc pairing. The numbers match our GHK-Cu 50mg and GHK-Cu 100mg protocol pages.
Researcher special: code SAVE25 or PLATINUM25 unlocks 25% off GHK-Cu 50mg, GHK-Cu 100mg, and bacteriostatic water. Every vial ships with a batch-matched COA at 99%+ HPLC purity.
Standard reconstitution: add exactly 3 mL bacteriostatic water.
| Metric | Value |
| Peptide | 50 mg |
| Bac water | 3 mL |
| Concentration | ≈16.7 mg/mL |
| Per 10 units | ≈1.67 mg |
Standard reconstitution: add exactly 3 mL bacteriostatic water (kept concentrated so the full dose fits a 3 mL vial).
| Metric | Value |
| Peptide | 100 mg |
| Bac water | 3 mL |
| Concentration | ≈33.3 mg/mL |
| Per 6 units | ≈2 mg |
| Per 5 units | ≈1.67 mg |
The 100mg vial is twice as concentrated, so it needs fewer units for the same milligrams and lasts longer — the economical pick for extended runs.
GHK-Cu delivers copper, so balance it with zinc 15–30 mg elemental every other day (AM with food, cap 40 mg/day total) — especially on runs over 8 weeks or low-zinc diets. Long-term use raises copper levels; consult a knowledgeable provider before extended cycles.
GHK-Cu is the anchor of the GLOW and KLOW blends and the Wolverine Repair Stack. For the research background, see the GHK-Cu copper peptide research overview. Reconstitute with 3 mL, refrigerate, use within 4 weeks.
