Tesamorelin

FDA Approved

Also: Egrifta

💉GHRH Analog

How It Works

Stimulates GH for fat metabolism. Binds to GHRH receptors on the pituitary gland to stimulate natural growth hormone production, specifically targeting visceral adipose tissue.

Primary Benefits

1Visceral fat reduction
2body recomposition

Key Studies

Tesamorelin visceral fat reduction (FDA trial)

Falutz et al. (JAMA): Randomized, double-blind, placebo-controlled Phase 3 trial showing 15.2% reduction in visceral adipose tissue vs. 5% increase in placebo. FDA-approved indication.

Tesamorelin 52-week extension study sustained VAT reduction

Falutz et al. (J. Clin. Endocrinol. Metab.): 52-week data confirming sustained 18% visceral fat reduction with continuous therapy, with reversal upon discontinuation.

Tesamorelin reduces liver fat in HIV lipodystrophy

Stanley et al. (Ann. Intern. Med.): RCT demonstrating tesamorelin reduces hepatic fat content in HIV-infected patients with abdominal fat accumulation.

Tesamorelin improves executive function in older adults

Baker et al.: GHRH treatment (tesamorelin) shows favorable effects on executive function and verbal memory in cognitively normal and mildly impaired older adults via IGF-1 elevation.

Tesamorelin IGF-1 effects and body composition (Phase 3)

Phase 3 trial showing ~80% increase in IGF-1 levels, improved body image distress scores, and significant trunk fat reduction across multiple patient populations.
