Tesamorelin dosage calculator

10 mg + 2 mL = 5 mg/mL, so 1 mg is 0.2 mL, or 20 units on a U-100 syringe. Change the vial, the water or the amount and the syringe updates.

10 mg + 2 mL = 5 mg/mL, so 1 mg is 0.2 mL, or 20 units on a U-100 syringe.

How much water for each Tesamorelin vial size?

Tesamorelin is sold in 2 common sizes (2 mg, 10 mg). The same water volume gives a different concentration in each, so the same reading means a different amount. Each cell shows mcg per unit with mg/mL in brackets.

How much bacteriostatic water for a 2 mg Tesamorelin vial?

1 mL → 2 mg/mL, so 1 mg is 50 units. 2 mL → 1 mg/mL, so 1 mg is 100 units. 3 mL → 0.667 mg/mL, so 1 mg is 150 units. The whole vial holds 2 draws of 1 mg.

How much bacteriostatic water for a 10 mg Tesamorelin vial?

1 mL → 10 mg/mL, so 1 mg is 10 units. 2 mL → 5 mg/mL, so 1 mg is 20 units. 3 mL → 3.33 mg/mL, so 1 mg is 30 units. The whole vial holds 10 draws of 1 mg.

Worked example: 10 mg vial, 2 mL, 1 mg

  1. Concentration. 10 mg ÷ 2 mL = 5 mg/mL (5,000 mcg/mL).
  2. Volume. 1 mg ÷ 5 mg/mL = 0.2 mL.
  3. Units. 0.2 mL × 100 = 20 units on a U-100 syringe.
  4. Check. One unit holds 50 mcg; 20 × 50 mcg = 1,000 mcg = 1 mg, which matches. The vial holds 10 draws of this size.

Tesamorelin: notes for the arithmetic

Tesamorelin is sold in both 2 mg and 10 mg vials. A five-fold difference in vial size means a five-fold difference in mg per unit for the same diluent volume.

For the lab procedure itself (materials, aseptic technique, mixing without foaming) see how to reconstitute peptides. For what bacteriostatic water is and how long an opened vial is kept, see the bacteriostatic water guide and the storage guide.

Frequently asked questions

How many units is 1 mg of Tesamorelin?

It depends on the water volume. 10 mg + 2 mL = 5 mg/mL, so 1 mg is 0.2 mL, or 20 units on a U-100 syringe. With 1 mL instead it would be 10 units.

How much bacteriostatic water for a 2 mg Tesamorelin vial?

There is no single correct volume. 1 mL gives 2 mg/mL (20 mcg per unit); 2 mL gives 1 mg/mL (10 mcg per unit); 3 mL gives 0.667 mg/mL (6.67 mcg per unit). Pick the volume that makes your reading easy to measure on the barrel you have.

How much bacteriostatic water for a 10 mg Tesamorelin vial?

There is no single correct volume. 1 mL gives 10 mg/mL (100 mcg per unit); 2 mL gives 5 mg/mL (50 mcg per unit); 3 mL gives 3.33 mg/mL (33.33 mcg per unit). Pick the volume that makes your reading easy to measure on the barrel you have.

How many mg of Tesamorelin is 10 units?

10 units on a U-100 syringe is 0.1 mL. At 5 mg/mL (10 mg in 2 mL) that is 0.5 mg (500 mcg). At a different concentration the answer is different.

Is this a Tesamorelin dosing calculator?

It is an arithmetic tool. It converts an amount you enter into a volume and a syringe reading; it does not suggest amounts, schedules or uses. An FDA-approved prescription product contains tesamorelin (Egrifta). It has its own labeled preparation instructions; research-labeled vials are not that product.
