Doses per Vial

Concentration = Vial Strength ÷ Water Volume. This tells you how many mg of peptide are in each mL of solution.

Volume to inject = Desired Dose ÷ Concentration. This is how much solution to draw into your syringe.

Syringe units: A standard 1 mL insulin syringe has 100 units. So 0.1 mL = 10 units, 0.5 mL = 50 units, etc.

Always use bacteriostatic water for reconstitution. Gently swirl — never shake — the vial after adding water. Store reconstituted peptides refrigerated.
