Enter your vial’s peptide amount, the volume of bacteriostatic water added, and your target dose — the calculator returns concentration, mcg per unit, and the exact units to draw for U-100 / U-50 / U-30 / custom syringes.
Reconstitution Calculator
Calculate syringe units from peptide amount, water, and desired dose. Research use only.

Quick reference
Standard reconstitution: adding 2 mL of bacteriostatic water to a 5 mg vial yields a 2.5 mg/mL (2,500 mcg/mL) solution. Always swirl gently — never shake — and use the vial promptly once reconstituted.
