Tesamorelin Reconstitution Calculator
Tesamorelin is a growth-hormone-releasing hormone (GHRH) analog. This page shows how to reconstitute it and read the result on a syringe — the calculator does the arithmetic for you.
Status: The prescription drug Egrifta is FDA-approved for HIV-associated lipodystrophy; research-chem tesamorelin is not the approved product and is not for human use.
The math
Concentration = vial ÷ water · Units = (dose ÷ concentration) × 100
Tesamorelin is reconstituted with bacteriostatic water. Reconstitute gently — swirl rather than shake — as with other peptides.

Frequently asked questions
How do I reconstitute Tesamorelin?
Add bacteriostatic water to the lyophilized vial to reach a concentration you can measure. For example, 5 mg in 2 mL of water gives 2.5 mg/mL, so each 10 units (0.1 mL) on a U-100 syringe contains about 250 mcg of Tesamorelin. Swirl gently rather than shaking.
How many units of Tesamorelin do I draw?
Divide your intended dose by the concentration to get the volume in mL, then multiply by 100 for a U-100 syringe. The calculator does this automatically once you enter your vial size, water volume and dose.
What vial sizes does Tesamorelin come in?
Tesamorelin is commonly supplied as 5 mg, 10 mg. The amount in the vial does not change with how much water you add — water only sets the concentration.
Is Tesamorelin approved for human use?
The prescription drug Egrifta is FDA-approved for HIV-associated lipodystrophy; research-chem tesamorelin is not the approved product and is not for human use. This calculator only performs arithmetic on the numbers you enter and does not recommend any dose.
