Reconstitute
Add bacteriostatic water to a lyophilized vial. The powder dissolves into solution — no chemistry, just mixing.
Find concentration
Concentration = peptide (mg) ÷ water (mL). This tells you how much peptide is in every mL of the solution.
Draw your dose
A U-100 insulin syringe reads in units where 100 units = 1 mL. Convert your dose in mg to mL, then to units.
Quick reference
1 mL
= 100 units
0.5 mL
= 50 units
1 mg
= 1,000 mcg
0.1 mL
= 10 units
Storage: Reconstituted peptides should be refrigerated (2–8°C) and used within the window on the product label — typically 14–28 days depending on the compound and preservative. Keep away from light.
