Comparison Table: GHK-Cu Vial Sizes by Protocol Type
50mg 5mL 10mg/mL 1–2mg 25–50 days 0.1–0.2mL Low (2–6mg if 2mg daily) Short protocols, single-cycle fit Optimal for most daily 2mg protocols. Minimizes waste and keeps one vial per cycle 100mg 20mg/mL 2–5mg 20–50 days 0.1–0.25mL Moderate (16–44mg if 2mg daily)

- 50mg
- 5mL
- 10mg/mL
- 1–2mg
- 25–50 days
- 0.1–0.2mL
- Low (2–6mg if 2mg daily)
- Short protocols, single-cycle fit
- Optimal for most daily 2mg protocols. Minimizes waste and keeps one vial per cycle
- 100mg
- 20mg/mL
- 2–5mg
- 20–50 days
- 0.1–0.25mL
- Moderate (16–44mg if 2mg daily)
- Higher-dose daily, or split reconstitution
- Works well for 3–4mg daily when full vial consumed in 28 days; otherwise requires splitting
- 10mL
- 2–3mg
- 33–50 days
- 0.2–0.3mL
- High (44mg+ if 2mg daily)
- Protocols exceeding 28 days
- Convenient injection volumes but forces wastage unless protocol is extended beyond standard cycle
- 200mg
- 3–5mg
- 40–66 days
- 0.15–0.25mL
- Very High (88mg+ if 3mg daily)
- Multi-month studies with multiple reconstitution cycles
- Requires splitting into two 100mg reconstitution events on staggered schedules to respect stability
