Peptide Calculator

Reconstituting a peptide vial? Enter your vial size, the amount of water you're adding, your syringe size, and your target dose — we'll show you exactly how many units to draw.

Your inputs

All four values are required to calculate your dose.

mg
Total amount of peptide in the vial (the powder).
ml
Bacteriostatic or acetic water you're adding to reconstitute.
U-100 insulin syringe (100 units = 1 ml).
mcg
How much peptide you want in each injection.
Used when you add this dose to your protocol.
Saves this dose to your Peptide Protocol on the My Program page.

Your dose

Draw the plunger to the highlighted mark.

Syringe volume is not sufficient for the specified dosage. Try a larger syringe, more water, or a smaller dose.

How reconstitution works

1

Prepare

Work on a clean surface. Wipe the vial stopper and the water vial with an alcohol swab and let them dry.

2

Add water slowly

Draw your chosen volume of bacteriostatic water and let it run gently down the inside wall of the vial — never directly onto the powder.

3

Dissolve gently

Swirl, don't shake. Let the peptide fully dissolve into a clear solution before drawing your dose.

4

Store

Keep the reconstituted vial refrigerated (2–8 °C) and protected from light. Use within the timeframe advised for your peptide.
