Overview of Tesamorelin

Stimulates growth hormone release from the pituitary, promoting targeted lipolysis in visceral fat depots and improving metabolic markers.

Growth hormone axis

Binds to GHRH receptors on pituitary somatotrophs, triggering growth hormone synthesis and pulsatile release.

Increases insulin-like growth factor 1 (IGF-1) levels, mediating anabolic and lipolytic effects.

Metabolic / fat reduction

Preferentially reduces visceral adipose tissue (VAT), targeting metabolically harmful deep abdominal fat.

Minimal effect on subcutaneous fat, specifically addressing central adiposity.

Reduces liver fat (hepatic steatosis) and improves liver enzymes (ALT, AST), with benefits for liver health.

Enhances triglyceride profiles in responders, improving metabolic markers.

Body composition

Increases muscle density (proposed), which may improve muscle quality independent of quantity changes
