How to use

1
Choose vial size
Pick the vial you bought — we support anything from 2mg to 30mg. Default is 50mg.
2
Pick your reconstitution volume
Add bacteriostatic water. Most users pick 1ml, 2ml, or 3ml. Smaller volumes mean more concentrated — fewer marks on the syringe per dose.
3
Enter your target dose
Typical research protocols for GHK-Cu (injectable): 1–3 mg subcutaneous, 3–5x per week. The calculator will tell you how many units on a U-100 insulin syringe.
4
Calculate vial duration
The tool multiplies your dose by frequency to give you the total days per vial — so you know how many to order.

Cross-reference your vial plan with live vendor pricing — the cheapest vendor for your chosen vial size might not be the cheapest per-mg.
