Tesamorelin

In plain terms

Tesamorelin is a synthetic analogue of growth-hormone-releasing hormone. Clinical research has studied it for effects on visceral fat and on growth hormone release. Supplied here as a laboratory reference standard.

Research overview

Tesamorelin is a synthetic 44-amino acid analog of growth hormone-releasing hormone (GHRH). It is one of the few peptides with FDA approval for a specific clinical indication. Laboratory and clinical research has extensively studied its effects on growth hormone secretion, body composition, and metabolic parameters in research settings.

What has been studied

1. 1

   A growth-hormone-releasing analogue

   Tesamorelin is a modified form of GHRH, the signal the hypothalamus uses to tell the pituitary to release growth hormone. It prompts release rather than supplying the hormone.

2. 2

   Fat distribution research

   It has the most substantial clinical literature of any compound in this catalogue, centred on visceral adipose tissue.

3. 3

   IGF-1 as the readout

   Studies typically measure IGF-1 levels, since that is the downstream marker of growth-hormone activity.
