Know your numbers before you reconstitute

Reconstituting lyophilized peptides with bacteriostatic water turns milligrams of powder into precise, repeatable doses. This free calculator works out the concentration, the volume to draw per dose, and how many doses each vial provides — in seconds and with no login.

Concentration (mg/ml)

See exactly how many mg of peptide are in each millilitre of bacteriostatic water you add, so every draw is consistent.

Dose volume & syringe units

Get each application in ml and the matching marks on a U100 insulin syringe — no manual unit conversion.

Applications per vial

Check how many doses your vial supports at your target dose before you mix, so you always order enough.

Free to use — no login required

The calculator runs entirely in your browser. No account, no email sign-up, and nothing to download — results update instantly as you adjust the inputs.
