Mechanism of Action

How Does Thymosin Beta (TB-4) Work?

Sermorelin mimics the body’s natural GHRH, binding to receptors in the anterior pituitary to trigger GH secretion.

This process has been researched to increase circulating insulin-like growth factor-1 (IGF-1) levels, which play a central role in muscle growth, tissue regeneration, fat metabolism, and anti-aging.

Studies show that Sermorelin provides a gradual, sustained improvement in metabolic and structural function without disrupting the body’s hormonal balance.
