How the math works
Three formulas, checked twice — the same engine that powers the Zyra Track app:
- concentration (mg/mL) = peptide in vial (mg) ÷ BAC water (mL)
- draw volume (mL) = dose ÷ concentration
- U-100 units = draw volume (mL) × 100
Worked example: 10 mg Tesamorelin + 2 mL water = 5 mg/mL. A 2 mg dose is then 2 mg ÷ 5 mg/mL = 0.4 mL = 40 units on a U-100 insulin syringe.

Frequently asked
How much BAC water should I add to a 10 mg Tesamorelin vial?
There is no single correct amount — the water volume sets the concentration, not the dose. Adding 2 mL to 10 mg gives 5 mg/mL, which puts a 2 mg draw at 40 units on a U-100 insulin syringe. More water = larger, easier-to-measure draws; less water = smaller draws.
How many units is 2 mg of Tesamorelin?
It depends entirely on your concentration. At 5 mg/mL (10 mg + 2 mL), 2 mg is 40 units on a U-100 syringe. Use the calculator above with your own vial and water volumes.
What is the half-life of Tesamorelin?
Tesamorelin's reported half-life is ≈ 26–38 min. See our cited half-life reference for the decay curve and clearance math.
