Tesamorelin reconstitution calculator
Tesamorelin (brand Egrifta, Egrifta SV, Egrifta WR; developmental code TH9507) is a synthetic analog of growth hormone-releasing hormone (GHRH) that stimulates the pituitary to release endogenous growth hormone. It is FDA-approved to reduce excess visceral abdominal fat in HIV-infected patients with lipodystrophy, where a 26-week trial cut visceral adipose tissue by roughly 15% versus a 5% increase on placebo (Falutz 2007, N Engl J Med, PMID 18057338). It is a lyophilized powder reconstituted before once-daily subcutaneous injection, with a very short elimination half-life of about 8-11 minutes and subcutaneous bioavailability under 4% per the Egrifta SV/WR FDA labels (DailyMed 2024).
