Tesamorelin dosage calculator

Add your chosen volume of bacteriostatic water to the lyophilized vial, directing the stream gently against the glass wall, and swirl slowly (do not shake) until fully dissolved. The FDA-approved Egrifta products use sterile water for injection; research-grade vials are typically reconstituted with bacteriostatic water to extend shelf life. The calculator above converts your vial size and water volume into the exact units to draw for your target dose.

It depends on your reconstitution concentration. With a 10 mg vial in 2 mL of bacteriostatic water (5 mg/mL), 2 mg is 0.4 mL, which is 40 units on a U-100 syringe. With the same vial in 1 mL (10 mg/mL), 2 mg is 0.2 mL, or 20 units. Enter your own vial size and water volume above to get your exact number.

The only FDA-approved use of tesamorelin is for the reduction of excess abdominal fat in HIV-infected adults with lipodystrophy. The Egrifta SV prescribing information specifies 1.4 mg subcutaneously once daily; the Egrifta WR formulation specifies 1.28 mg once daily. Research use at other doses is off-label. This calculator performs math on the values you enter; it does not recommend any dose. Always consult a licensed clinician before using any peptide or hormone.

Tesamorelin has an extremely short plasma half-life: approximately 8-11 minutes after subcutaneous injection, per the Egrifta prescribing information. At that elimination rate, the peptide clears from plasma within a couple of hours, so there is no meaningful week-over-week accumulation to model. The calculator still computes your concentration, draw volume, and doses per vial.
