Research overview

DoseGear research brief

The Tesa/IPA blend combines two complementary growth hormone secretagogues: Tesamorelin (a GHRH analog that stimulates GH release from the pituitary) and Ipamorelin (a selective ghrelin mimetic/GHRP that amplifies GH pulses). This combination addresses both the GHRH and GHRP pathways for synergistic GH release. Common formulations include 5mg/5mg (1:1 ratio) and 10mg/3mg (higher Tesamorelin) variants. Tesamorelin is FDA-approved for HIV-associated lipodystrophy, while Ipamorelin remains investigational.

Mechanism of action

The blend leverages two distinct GH-releasing pathways: Tesamorelin is a synthetic GHRH analog that directly stimulates growth hormone-releasing hormone receptors on pituitary somatotrophs, triggering GH synthesis and secretion in a pulsatile, physiological manner. Ipamorelin is a selective ghrelin receptor (GHS-R1a) agonist that amplifies GH pulses without significantly affecting cortisol or prolactin. Together, they produce synergistic GH release greater than either compound alone, while maintaining the body's natural feedback mechanisms.
