Peptide Calculator
Enter a vial amount, solution volume and target amount to see concentration, volume and syringe units. Presets are shortcuts; you can always type your own values.

How it is calculated
Concentration = total peptide amount ÷ solution volume.
Volume = target amount ÷ concentration.
U-100 syringe units = volume in mL × 100.
1 mg = 1000 mcg.
Worked example (mathematical example only): 5 mg in 2 mL gives 2.5 mg/mL (2500 mcg/mL). A 250 mcg target is 250 ÷ 2500 = 0.1 mL, which is 10 units on a U-100 syringe.
