Tesamorelin is a synthetic analogue of growth hormone-releasing hormone (GHRH), consisting of the full 44-amino acid sequence of endogenous GHRH with a trans-3-hexenoic acid group attached to the N-terminus. This modification significantly enhances its stability against enzymatic degradation while preserving its biological activity at the GHRH receptor.
Researchers have studied Tesamorelin for its ability to stimulate the pituitary gland’s natural growth hormone secretion. Unlike direct GH administration, Tesamorelin works through the body’s endogenous feedback mechanisms, stimulating pulsatile GH release. Research has examined its downstream effects on IGF-1 levels and various metabolic parameters in preclinical models.
Clinical and preclinical research has investigated Tesamorelin’s effects on visceral adipose tissue accumulation, particularly in populations with metabolic disruptions. Studies have also examined its influence on cognitive function markers and lipid metabolism in research settings. Tesamorelin’s mechanism of stimulating natural GH pulsatility rather than providing exogenous GH has made it a compound of significant scientific interest for understanding the GH axis.
