Peptide Reconstitution Calculator

Work out your concentration, and exactly how much to draw, from the amount in your vial, the bacteriostatic water you add, and your target dose.

Your numbers

Draw this much

Draw to
25.0units
Concentration

Volume to draw
0.25 mL
Doses in vial
20 doses
Leftover after those doses
0 mL
This exceeds the syringe's capacity — split the dose or use a larger syringe.
How this is calculated

Concentration is the peptide amount spread through the total liquid volume:

concentration (mcg/mL) = vial amount (mg) × 1000 ÷ water added (mL)

The volume to draw is your target dose divided by that concentration:

volume to draw (mL) = dose (mcg) ÷ concentration (mcg/mL)

For insulin-style syringes, the barrel is marked on a U-100 scale (100 units = 1 mL), so:

units to draw = volume to draw (mL) × 100

Doses in the vial is how many full draws of that size fit in the total water added:

doses in vial = ⌊water added (mL) ÷ volume to draw (mL)⌋
This tool performs arithmetic on the numbers you enter — it doesn't look up or recommend dosing. Double-check figures against your own protocol or a professional before drawing anything.
