Tesamorelin is an FDA-approved synthetic GHRH analog designed for HIV-associated lipodystrophy treatment. It provides selective visceral fat targeting with 15-20% visceral fat reduction in clinical trials while preserving subcutaneous fat.

Mechanism of Action

Subcutaneous injection provides optimal bioavailability for GHRH receptor binding and pulsatile GH release stimulation, selectively targeting visceral adipose tissue while sparing subcutaneous fat.

Key Benefits

  • FDA-approved formulation
  • Selective visceral fat targeting (15-20% reduction)
  • Proven clinical efficacy
  • Standardized dosing
  • 37% liver fat reduction in NAFLD
  • Preserved subcutaneous fat

Combined use may elevate IGF-1 supraphysiologically.

monitor
Sermorelin

Similar mechanism; risk of excessive effects at higher doses.

monitor
Insulin

3.3-fold diabetes risk increase; monitor glucose closely.

monitor
Metformin

May mitigate glucose intolerance associated with tesamorelin.

compatible
Prednisone

Decreases corticosteroid effectiveness.

monitor
Octreotide

Blocks GH release, negates tesamorelin effects.

avoid
Growth Hormone

Redundant; risk of acromegaly-like effects.

avoid
Week 1-2

IGF-1 levels begin to rise, possible mild water retention or joint discomfort

Week 4-6

Early metabolic changes; improved energy/sleep

Week 8-12

Visible visceral fat reduction begins, waist circumference may decrease

Week 12-26

Peak effects achieved with significant body composition improvements
