Frequently Asked
How do I reconstitute Tesamorelin?
Add 1 mL of bacteriostatic water to a 10 mg vial, injecting slowly down the inside wall. Swirl gently; never shake. This yields a concentration of 10 mg/mL.
What is the recommended dose of Tesamorelin?
A typical research dose is 2 mg. Consult the ASCEND calculator for your specific vial concentration and draw volume.
How many doses are in a Tesamorelin vial?
A 10 mg vial reconstituted with 1 mL BAC water yields approximately 5 doses at 2 mg each.
How many IU is 2 mg of Tesamorelin on a syringe?
With a 10 mg vial reconstituted in 1 mL bacteriostatic water, the concentration is 10 mg/mL. For a 2 mg dose: Volume = 2 mg ÷ 10 mg/mL = 0.2 mL. Draw to the 20 line on a 100-unit insulin syringe. You can adjust these values in the ASCEND calculator for any vial size.
What does a Tesamorelin dosage calculator do?
A Tesamorelin dosage calculator converts your vial size and BAC water volume into an exact syringe draw in IU. Enter your vial strength (10 mg), reconstitution volume (1 mL), and target dose to get the precise line to draw on an insulin syringe.
What is the Tesamorelin reconstitution calculator formula?
Draw volume (mL) = Dose (mg) divided by Concentration (mg/mL). For a 10 mg vial with 1 mL BAC water: concentration = 10 mg/mL. For a 2 mg dose, the ASCEND calculator gives the exact IU line on your syringe instantly.
Peptide Intelligence
What is the half-life of Tesamorelin?
Tesamorelin has a short half-life of approximately 26 minutes after subcutaneous injection due to rapid DPP-IV cleavage. Despite this, its effects on GH release persist for several hours, and daily administration produces meaningful IGF-1 elevation and visceral fat reduction.
What is the FDA-approved indication for Tesamorelin?
Tesamorelin (Egrifta) is FDA-approved for the treatment of HIV-associated lipodystrophy, specifically excess visceral abdominal fat in HIV-infected patients on antiretroviral therapy. This is among the only FDA-approved GHRH analog applications.
Why must Tesamorelin be injected within hours of reconstitution?
Tesamorelin is highly unstable in solution due to peptide bond susceptibility to hydrolysis. Reconstituted Tesamorelin should be injected within 3 hours of preparation. Never pre-load syringes for later use. Stability decreases rapidly even under refrigeration.
