The short answer
Mixed with 2 mL of bacteriostatic water, a 20 mg vial of Tesamorelin holds 10 mg/mL. A 2 mg dose is then 20 units (0.20 mL) on a U-100 insulin syringe, and the vial holds about 10 doses of that size. Taken 1× per day, it lasts about 10 days.
How much water
The water only sets the strength; the dose and the number of doses in the vial stay the same. Draws are on a U-100 insulin syringe, where 1 unit is 0.01 mL.
| Water added | Strength | Per syringe unit | Draw for 2 mg |
|---|---|---|---|
| 1 mL | 20 mg/mL | 200 mcg | 10 units (0.10 mL) |
| 2 mL | 10 mg/mL | 100 mcg | 20 units (0.20 mL) |
| 3 mL | 6.667 mg/mL | 66.7 mcg | 30 units (0.30 mL) |

Draws over 100 units show in mL. Faded values are under 2 units, which is hard to measure. Check that your vial holds the larger volumes.
Where the doses come from
- Label Egrifta WR: 1.28 mg once daily. Egrifta SV: 1.4 mg once daily. The two aren’t interchangeable. The original Egrifta 1 mg vials were dosed at 2 mg daily.
- Community Research vials: 1–2 mg once daily, often following the original 2 mg label dose.
Doses are what labels, trials or community reports reference, not recommendations. Tesamorelin’s page has the cycle, side effects, cautions and sources.
Mixing and storage
- PrepareLet a refrigerated vial come to room temperature, and wipe both stoppers with an alcohol swab.
- Add 2 mLDraw 2 mL of bacteriostatic water and let it run slowly down the inside wall of the vial.
- Swirl, don’t shakeSwirl gently until the powder dissolves and the liquid is clear.
- Label itWrite the date and the strength, 10 mg/mL, on the vial.
Storage: Research vials, mixed: 2–8 °C.

Questions
How much water do I add to a 20 mg vial of tesamorelin?
There’s no single right amount: the water only sets the strength. With 2 mL of bacteriostatic water, a 20 mg vial holds 10 mg/mL. With 1 mL it’s 20 mg/mL; with 3 mL it’s 6.667 mg/mL. Less liquid makes each dose a smaller draw; more makes small doses easier to measure.
How many units is 2 mg of tesamorelin?
With 2 mL in a 20 mg vial, 2 mg is 20 units (0.20 mL) on a U-100 insulin syringe. With 1 mL, 10 units (0.10 mL); with 3 mL, 30 units (0.30 mL).
How many doses are in a 20 mg vial of tesamorelin?
About 10 doses of 2 mg, or 20 of 1 mg or 13 of 1.5 mg. Taken 1× per day at 2 mg, it lasts about 10 days.
How long does a mixed vial of tesamorelin keep?
Research vials, mixed: 2–8 °C.
