How Reconstitution Works

Peptides ship as a lyophilized (freeze-dried) powder. Before use, you add bacteriostatic water to dissolve the powder. The amount of water you add determines the concentration, which determines how much liquid to draw for your target dose.

The formula: Concentration (mcg/mL) = Peptide amount (mcg) / Water volume (mL). Then: Units to draw = Desired dose (mcg) / Concentration (mcg/mL) x 100.

A standard insulin syringe holds 1 mL = 100 units. So 0.1 mL = 10 units. This calculator does the math for you.
