Four questions, then the result: how many units to pull for the amount you enter. Arithmetic only. What amount, if any, is a question for you and your doctor.

1. How much peptide is in the vial?
2. How much bacteriostatic water will you add?
3. How much peptide per draw?Selected: 250 mcg = 0.25 mg

mcg is a microgram: one thousandth of a milligram. 1 mg = 1,000 mcg, so 250 mcg is 0.25 mg. Vials are often labelled in mg; smaller amounts are easier to write in mcg. Certificates sometimes write it µg; it is the same unit.

Type in mcg or mg; the switch converts the box.
4. What is the total volume of your syringe?
Concentration2.5 mg/ml2500 mcg per ml
Draws per vial20whole draws of 250 mcg
Units to draw10 units0.1 ml
Aliquots per vial20of 0.1 ml each
Draw to 10 units on the 1.0 ml (100-unit) syringe0.1 ml · 250 mcg

How it is worked out: 5 mg ÷ 2 ml = 2.5 mg/ml. One unit is 0.01 ml, so one unit holds 25 mcg. 250 mcg ÷ 25 mcg = 10 units (0.1 ml). 5 mg ÷ 0.25 mg = 20 whole draws, and 2 ml ÷ 0.1 ml = 20 aliquots. The syringe size changes the picture, not the maths.

Arithmetic only. Check every result yourself before you rely on it.

Per unit = mg ÷ ml ÷ 100, in mcg
More waterLower concentration, more units per draw. Easier to read on the syringe.
Less waterHigher concentration, fewer units per draw. Fits a small syringe.
