How much bacteriostatic water to reconstitute Tesamorelin (5 mg vial)?
For a 5 mg Tesamorelin vial, the volume of bacteriostatic water you add sets the concentration: 1 ml gives 5 mg/ml; 1.5 ml gives 3.33 mg/ml; 2 ml gives 2.5 mg/ml; 2.5 ml gives 2 mg/ml; 3 ml gives 1.67 mg/ml. At the 2 ml reference volume the solution is 2.5 mg/ml (25 mcg per U-100 syringe unit). Research Use Only — these are solution concentrations, not amounts to administer.
| Bacteriostatic water | Concentration | Mass per U-100 unit |
|---|---|---|
| 1 ml | 5 mg/ml | 50 mcg |
| 1.5 ml | 3.33 mg/ml | 33 mcg |
| 2 ml | 2.5 mg/ml | 25 mcg |
| 2.5 ml | 2 mg/ml | 20 mcg |
| 3 ml | 1.67 mg/ml | 17 mcg |
How much bacteriostatic water to reconstitute Tesamorelin (10 mg vial)?
For a 10 mg Tesamorelin vial, the volume of bacteriostatic water you add sets the concentration: 1 ml gives 10 mg/ml; 1.5 ml gives 6.67 mg/ml; 2 ml gives 5 mg/ml; 2.5 ml gives 4 mg/ml; 3 ml gives 3.33 mg/ml. At the 2 ml reference volume the solution is 5 mg/ml (50 mcg per U-100 syringe unit). Research Use Only — these are solution concentrations, not amounts to administer.
| Bacteriostatic water | Concentration | Mass per U-100 unit |
|---|---|---|
| 1 ml | 10 mg/ml | 100 mcg |
| 1.5 ml | 6.67 mg/ml | 67 mcg |
| 2 ml | 5 mg/ml | 50 mcg |
| 2.5 ml | 4 mg/ml | 40 mcg |
| 3 ml | 3.33 mg/ml | 33 mcg |
Each “mass per U-100 unit” figure is the amount one unit on a U-100 insulin syringe (1 unit = 0.01 ml) holds at that concentration — a property of the prepared solution, not an amount to administer.

U100 insulin syringe (1 ml). The liquid shade reflects the concentration; each mark is labelled with the mass it holds at that concentration — not an amount to administer.
How to reconstitute Tesamorelin
Tesamorelin is supplied as a lyophilized powder in 5 mg and 10 mg vials. Choose the vial strength, then set the bacteriostatic-water volume; add the water slowly against the inside of the vial and let the powder dissolve without shaking. The calculator divides the milligrams by the water volume to give the concentration in mg/ml and the mass at each U100 syringe mark.
At 2 ml the 5 mg vial gives 2.5 mg/ml and the 10 mg vial gives 5 mg/ml. Across 1–3 ml the 5 mg vial spans 5 to about 1.67 mg/ml and the 10 mg vial spans 10 to about 3.3 mg/ml.
Tesamorelin reconstitution — frequently asked questions
How much bacteriostatic water to reconstitute Tesamorelin?
Any 1–3 ml volume; it sets the concentration. The 5 mg vial reaches 5 mg/ml and the 10 mg vial 10 mg/ml at 1 ml, halving toward 3 ml.
What concentration does a 5 mg or 10 mg Tesamorelin vial give?
The vial milligrams divided by the water millilitres: 5 to 1.67 mg/ml (5 mg) or 10 to 3.3 mg/ml (10 mg) across 1–3 ml. The calculator reports the exact mg/ml and per-mark mass.
What solvent reconstitutes Tesamorelin?
Bacteriostatic water (sterile water with 0.9% benzyl alcohol). Add it down the vial wall and let the powder dissolve without shaking.
How is reconstituted Tesamorelin stored?
Refrigerate at 2–8°C, protected from light. Most reconstituted peptide solutions hold stability for up to 30 days refrigerated; aliquot before freezing to avoid repeated freeze-thaw cycles. The lyophilized vial is stored at −20°C.
