Peptide reconstitution & dosing calculator

Enter the vial amount, the bacteriostatic water you added, and your target dose. Get the exact units to draw on an insulin syringe, the concentration, doses per vial, and cost per dose. Works for any peptide in the catalog.

The milligrams printed on your vial label.

mg

How much water you mix into the vial. More water makes small doses easier to draw.

mL
Recommended: 3 mL for 10 mg (~3.3 mg/mL)

How much peptide you want in each draw (1 mg = 1000 mcg).

mcg

How often you draw — used for vial duration and monthly cost.

/wk

Match the insulin syringe you're using (100 units = 1 mL).

Mix 10 mg of peptide with 2 mL of bacteriostatic water. Then draw to the 5-unit mark (0.05 mL) on a 0.5 mL (50u) syringe for each 250 mcg dose. One vial gives about 40 doses — roughly 6 weeks at 7 per week.

How to use it

  1. 1Read your vial label. Enter how many milligrams of peptide the vial holds — or tap a product preset to fill it in.
  2. 2Pick how much water. Enter the bacteriostatic water you'll mix in. More water = a lower concentration and a bigger, easier-to-measure draw.
  3. 3Set your target dose. Enter the dose you want per draw, in micrograms. The calculator shows the exact unit mark to fill the syringe to.
  4. 4Read the plain-English answer. It tells you the units to draw, how many doses the vial holds, how long it lasts, and the cost per dose.

How to Reconstitute Peptides

Concentration

Concentration = peptide (mg) ÷ water (mL). More water means a lower concentration and a larger volume to draw for the same dose.

Units on a U-100 syringe

A U-100 insulin syringe holds 100 units per millilitre. Units to draw = dose volume (mL) × 100. Match the syringe size to your dose.

Doses per vial & cost

Doses per vial = total mcg ÷ dose. Add the vial price to see cost per dose — useful for comparing protocols across the catalog.
