Scientific Background

Tesamorelin is a stabilized synthetic analog of growth hormone-releasing hormone (GHRH) designed to stimulate the body's own production of growth hormone in a controlled, pulsatile manner. Developed as a modified 44-amino-acid peptide with a trans-3-hexenoyl group at the N-terminus, it resists rapid breakdown and effectively binds pituitary GHRH receptors — leading to increased endogenous GH secretion and elevated IGF-1 levels which promote lipolysis, especially in visceral adipose tissue. The 20 mg vial provides approximately 10 maintenance doses at 2 mg/day, ideal for extended protocols.

Intended Research Use

Reduces visceral (abdominal) fat accumulation
Improves lipid profiles and metabolic markers
Supports lean muscle preservation during fat loss
Enhances overall body composition
May improve liver fat content in metabolic conditions
Physiologic GH/IGF-1 elevation without broad GH side effects
