Tesamorelin is a synthetic analog of growth hormone-releasing factor (GRF) with a trans-3-hexenoic acid modification that enhances its stability and half-life. It acts on the GHRH receptor to stimulate growth hormone secretion. It is FDA-approved under the brand name Egrifta for HIV-associated lipodystrophy and has been studied in research settings for its effects on visceral fat reduction, GH/IGF-1 axis modulation, and metabolic parameters. For research use only outside of approved indications.
Q: What chemical modification distinguishes Tesamorelin from standard GHRH?
A: Tesamorelin incorporates a trans-3-hexenoic acid group at the N-terminus of the GHRH(1-44) sequence. This modification increases resistance to enzymatic degradation and extends the peptide’s stability and half-life compared to native GHRH, making it more practical for research protocols.
Q: What has research shown about Tesamorelin’s effects on body composition?
A: Clinical and preclinical research has documented Tesamorelin’s ability to reduce visceral adipose tissue while preserving lean mass in subjects with GH insufficiency or HIV-related lipodystrophy. The mechanism involves increased GH pulsatility and downstream IGF-1 signaling affecting lipid metabolism.
