Tesamorelin Reconstitution Calculator
Tesamorelin is supplied as a lyophilised powder for reconstitution. Enter your vial amount, the volume of diluent you are adding and your dose to convert it into exact syringe units.
100 units per mL — pick the syringe you have.
Draw to
BAC water
on a U-100 insulin syringe
Drag the syringe to set your dose, or type the values above.
Enter your vial amount and dose, then type the bacteriostatic water or drag the syringe to see the exact units to draw.
Vial sizes and water volumes are shown for convenience — the dose field is deliberately not prefilled and has no suggestions. Enter your own numbers.
Never do this math twice.
The Pep AI app remembers your vials and doses, shows an interactive syringe you draw to, counts down the doses left in each vial, and reminds you when it's time. Free on iOS and Android.
How the conversion works
Three steps. The dose below is arbitrary and shown only to demonstrate the arithmetic:
1. Concentration
Vial amount ÷ water added. A 2 mg vial with 2 mL of water is 1 mg/mL.
2. Volume per dose
Your dose ÷ concentration. A 1 mg dose at 1 mg/mL is 1 mL.
3. Units to draw
Volume per dose × 100 for a U-100 syringe (or × 40 for a U-40). 1 mL on a U-100 syringe is 100 units.
Worked example
You have a 2 mg vial, you want a 1 mg dose, and you add 2 mL of bacteriostatic water. Concentration is 2 ÷ 2 = 1 mg/mL. Volume per dose is 1 ÷ 1 = 1 mL. On a U-100 syringe that's 1 × 100 = 100 units, and the vial holds 2 doses.
Follow the prescribing information, not a calculator
Tesamorelin is an FDA-approved medicine with an approved indication and prescribing information, which makes it different in kind from most compounds this tool is used for. Where an approved product's labelling specifies a reconstitution procedure and a diluent, that labelling governs — it was validated for that product, and a general calculator is not a substitute for it.
What this calculator is useful for is understanding the arithmetic and checking your own working. It is a unit converter, not a preparation protocol.
