Tesamorelin reconstitution calculator.
Work out the concentration of a reconstituted Tesamorelin vial. Presets match the 5 mg / 10 mg formats we stock, and the reference table below is calculated for those exact vials. Research use only.
This tool reports concentration only. It is not dosing guidance, and nothing here is for human use.
Tesamorelin concentration reference table
Every combination of the Tesamorelin vial sizes we stock and the bacteriostatic water volumes people most often add.
| Vial | BAC water | Concentration | Per 100 µL aliquot |
|---|---|---|---|
| 5 mg | 1 ml | 5 mg/ml | 0.5 mg (500 mcg) |
| 5 mg | 2 ml | 2.5 mg/ml | 0.25 mg (250 mcg) |
| 5 mg | 3 ml | 1.667 mg/ml | 0.167 mg (167 mcg) |
| 5 mg | 5 ml | 1 mg/ml | 0.1 mg (100 mcg) |
| 10 mg | 1 ml | 10 mg/ml | 1 mg (1,000 mcg) |
| 10 mg | 2 ml | 5 mg/ml | 0.5 mg (500 mcg) |
| 10 mg | 3 ml | 3.333 mg/ml | 0.333 mg (333 mcg) |
| 10 mg | 5 ml | 2 mg/ml | 0.2 mg (200 mcg) |
How the calculation works
Concentration is the mass of peptide divided by the volume of solvent. A vial holding 5 mg reconstituted with 2 ml of bacteriostatic water gives 2.5 mg/ml, so a 100 µL aliquot contains 0.25 mg. The powder itself adds no meaningful volume at these masses, which is why the water volume alone sets the concentration.
Handling in the Vietnamese climate
Sealed lyophilized vials are stable at room temperature in transit, which is why the material ships dry rather than cold. Once reconstituted, the solution is kept refrigerated and shielded from light. Bacteriostatic water is the usual solvent because the benzyl alcohol in it lets a vial be entered more than once.
What is Tesamorelin?
A stabilised analog of growth-hormone-releasing hormone.
Tesamorelin is a synthetic version of GHRH. The natural hormone the hypothalamus uses to tell the pituitary to release growth hormone. The full natural sequence is 44 amino acids long and degrades quickly; tesamorelin attaches a small chemical group to the end, which blocks the enzyme that would otherwise cut it apart.
It works one step upstream: rather than supplying growth hormone, it signals the body's own pituitary to release it. It is an approved medicine in the United States under the name Egrifta.

Common questions
What is Tesamorelin?
A synthetic analog of growth-hormone-releasing hormone (GHRH), stabilised with a chemical group that blocks the enzyme which would normally degrade it. It is approved in the US as Egrifta. Listed here as a non-clinical research material.
How is Tesamorelin different from growth hormone?
It acts one step upstream. Growth hormone is the hormone itself; tesamorelin is the signal that tells the pituitary to release the body's own growth hormone.
How much bacteriostatic water do I add to a Tesamorelin vial?
There is no single correct volume. The water volume sets the concentration: more water gives a weaker solution and a larger aliquot for the same mass. Common choices are 1 to 5 ml. Enter your vial size above to see what each volume produces for 5 mg / 10 mg.
What concentration does a Tesamorelin vial give?
It depends entirely on the solvent volume. The reference table above lists every combination of the 5 mg / 10 mg vial format and 1, 2, 3 and 5 ml of bacteriostatic water.
Does the powder change the final volume?
Not measurably at these masses. A few milligrams of lyophilized peptide occupies a negligible volume, so the bacteriostatic water you add is effectively the final volume.
Can I use normal water or saline instead?
Bacteriostatic water is the standard solvent for multi-entry vials because it contains a preservative. Sterile water and saline have no preservative, so they are single-entry solvents.
