Peptide reconstitution calculator

Enter the vial contents, the intended diluent volume and the amount you want to calculate. This tool converts units; it does not choose a dose.

01 · Reconstitution

Peptide-to-water ratio

Adding diluent changes concentration, not the total amount of compound shown on the vial label.

The calculation uses the volume you enter; it cannot determine which diluent is compatible. Follow the instructions for the specific formulation.

Concentration5 mg/mL
Per 1 U-100 unit (0.01 mL)50 mcg
Per 10 U-100 units (0.1 mL)500 mcg
02 · Amount

Your dose

Enter an amount from the protocol you are consulting. 1 mg equals 1,000 mcg.

Frequency is used only to estimate the arithmetic number of days per vial. It does not change the calculated draw.

U-100 syringe in use

Each U-100 unit equals 0.01 mL on all three syringes. Graduations here are every 2 units.

Nearest graduation: 6 units = 300 mcg (+20% from the entered amount). The exact calculated draw remains 5 units.

The draw uses less than 20% of this syringe's scale, so its graduations may be difficult to read.

Concentration = vial contents ÷ diluent volume. Draw volume = entered amount ÷ concentration; 1 mL = 100 U-100 units. Diluent choice, storage and any prescription depend on the product and a qualified clinician. Read the guides.
