A 5 mg Tesamorelin vial mixed with 2 ml of bacteriostatic water holds 2.5 mg/ml. A 2 mg dose is 0.80 ml — 80 units on a U-100 insulin syringe — and the vial holds 2 doses of that size.
Units on a U-100 insulin syringe (100 units = 1 ml) for Tesamorelin doses from 1 mg to 4 mg, by how much bacteriostatic water is in a 5 mg vial. The highlighted row is the 2 mg dose used above.
| Dose | 1 ml water 5 mg/ml | 2 ml water 2.5 mg/ml | 3 ml water 1.67 mg/ml | Doses per vial |
|---|---|---|---|---|
| 1 mg | 20 u 0.20 ml | 40 u 0.40 ml | 60 u 0.60 ml | 5 |
| 2 mg | 40 u 0.40 ml | 80 u 0.80 ml | 1.20 ml over 100 u | 2 |
| 3 mg | 60 u 0.60 ml | 1.20 ml over 100 u | 1.80 ml over 100 u | 1 |
| 4 mg | 80 u 0.80 ml | 1.60 ml over 100 u | 2.40 ml over 100 u | 1 |
A 80-unit draw needs a full 1 ml insulin syringe (100-unit capacity). Using less water concentrates the vial and shrinks the draw.
Unit math only, not a dosing recommendation. The dose range is what published protocols and trials describe; see the Tesamorelin guide for sources.
Tesamorelin is a stabilized analog of human GHRH, FDA approved for reducing excess visceral adipose tissue in HIV-associated lipodystrophy. It is studied for broader visceral fat and metabolic effects.
Half-life: Approximately 30 minutes
Typical dose range: 1–2 mg daily subcutaneous
Class: GHRH analog
Regulatory status: FDA approved as Egrifta for HIV-associated lipodystrophy (visceral fat reduction).

Need a different unit or a different question? The peptide dose converter moves a dose between mcg, mg and IU, and the Tesamorelin half-life chart shows how concentration accumulates across a dosing cadence. Loading Tesamorelin into a reusable 3 ml pen instead of drawing it with a syringe? The peptide pen calculator turns the same vial into mcg per click and clicks to dial. All of them are listed on the free peptide tools page.
Both. This Tesamorelin calculator converts vial strength, bacteriostatic-water volume, and target dose into milliliters and insulin-syringe units. It does not recommend a medical dose.
This page is pre-filled with 2 ml of bacteriostatic water for a 5 mg Tesamorelin vial because that is a common research ratio. You can adjust the water amount in the full calculator.
80 units on a U-100 insulin syringe, when a 5 mg vial is mixed with 2 ml of bacteriostatic water (2.5 mg/ml). That is 0.80 ml. With a different amount of water the unit count changes — the dose chart on this page lists 1 ml, 2 ml, 3 ml mixes.
2 doses of 2 mg. The number of doses depends only on vial strength and dose size — adding more or less water changes the volume of each draw, not how many draws the vial holds.
No. It only performs unit math. Dosing, titration, and whether Tesamorelin is appropriate are clinical decisions that should be made with a licensed healthcare professional.
Peptide Protocol remembers your Tesamorelin vial, shows the units for every dose, tracks what is left, and rotates injection sites for you.
