Peptide reconstitution calculator

Work out concentration and measured volume for a lyophilized research peptide, then see exactly where it lands on your syringe.

1Peptide in the vial

mg (or type your own)

2Bacteriostatic water you add

mL (or type your own)

3Amount per measurement

4Your syringe

Result

Concentration–mg per mL

Volume to draw–mL

Syringe marking–units

This calculator only does arithmetic. Products sold by Lodge are for laboratory research use only, not for human or animal consumption. Always double-check your numbers.

How the math works

Concentration = mg in the vial ÷ mL of water added.
Volume to draw = amount wanted ÷ concentration.
Syringe units = mL × 100 on a standard 1 mL insulin syringe (a 0.3 mL syringe holds 30 units, a 0.5 mL syringe holds 50).
