About Tesamorelin

A synthetic GHRH analogue approved by the FDA for HIV-associated lipodystrophy, studied for visceral fat reduction and metabolic effects.

Research dose ranges

  • Dose: 1000–2000 mcg per administration
  • Frequency: 1× per day
  • Route: subcutaneous
  • Half-life: ~0.43 hours
  • Cycle: 26 weeks on / 8 off

The FDA-approved clinical dose is 2 mg (2000 mcg) subcutaneously once daily. Some research protocols use 1 mg daily. Rotate injection sites to minimize local reactions.

Storage

Store lyophilized vials at 2–8°C. Reconstituted solution should be refrigerated and used within 24 hours per manufacturer guidance; some research protocols extend this to 72 hours under strict cold-chain conditions.

Tesamorelin calculator FAQ

How do I use the Tesamorelin calculator?+

Confirm your vial size in mg (default 1), set the diluent volume in mL (default 2.2), enter your target dose, and the calculator returns the concentration, the exact insulin-syringe units to draw, and how many doses your vial yields.

What's the standard Tesamorelin reconstitution?+

Most Tesamorelin research protocols reconstitute a 1 mg vial with 2.2 mL of bacteriostatic water, yielding 455 mcg/mL.

What syringe should I use for Tesamorelin?+

U-100 insulin syringes are standard for Tesamorelin subcutaneous administration. 0.5 mL barrels have clearer unit markings for typical research doses.

Does the Tesamorelin calculator support mg and IU?+

Yes. Enter your dose in mcg, mg, or IU. For IU, set the mcg-per-IU ratio (333 for HGH is a common default).
