Research Overview
Tesamorelin is a synthetic GHRH analog consisting of the full 44-amino acid human GHRH sequence with a trans-3-hexenoic acid modification at the N-terminus. This modification enhances stability and bioavailability. Tesamorelin received FDA approval in 2010 (Egrifta®) and is the only GHRH analog specifically approved for reducing excess abdominal fat in a clinical context, making it a uniquely positioned compound in metabolic research.
Mechanism of Action
Tesamorelin binds to the GHRH receptor on pituitary somatotrophs, stimulating endogenous GH synthesis and pulsatile release. The trans-3-hexenoic acid modification protects the N-terminus from enzymatic degradation (DPP-IV), extending its biological half-life. The resulting GH elevation drives hepatic IGF-1 production and promotes lipolysis, particularly in visceral adipose tissue. Importantly, Tesamorelin preserves the natural GH feedback loop, unlike exogenous GH administration.
Experimental Applications
Research includes visceral adipose tissue reduction studies, GH/IGF-1 axis modulation in aging models, trunk fat distribution analysis, cognitive function and hippocampal neurogenesis studies, lipid metabolism research, and comparative pharmacology against Sermorelin and CJC-1295.
