Overview
Tesamorelin is a synthetic analog of growth hormone-releasing hormone (GHRH). It consists of the full 44-amino acid sequence of endogenous GHRH with a trans-3-hexenoic acid modification at the N-terminus that increases plasma stability by reducing enzymatic degradation via dipeptidyl peptidase IV (DPP-IV). This modification extends the compound half-life compared to native GHRH without altering receptor binding characteristics. Tesamorelin has been extensively studied in preclinical research, providing a broad published literature base for researchers.
Alpha Tides PNW supplies Tesamorelin as a 10mg lyophilized compound for laboratory research use. For the tested sample, the attached Janoshik Certificate of Analysis reports 99.015% purity.
Research Applications
- GH/IGF-1 axis modulation: Pituitary growth hormone release and downstream IGF-1 pathway activation studies
- Visceral adiposity research: Adipose tissue reduction mechanisms and lipid metabolism studies
- Cognitive research models: Studies examining GH/IGF-1 axis activity and hippocampal function in aging research models
- Lipodystrophy models: Metabolic consequence and reversal research in preclinical lipodystrophy study designs
- Pituitary function studies: GHRH receptor pharmacology and somatotroph response characterization
- GHRH analog pharmacology: Plasma stability comparison studies between native GHRH and modified analogs
Research Notes
Tesamorelin acts on hypothalamic GHRH receptors (GHRHR) on pituitary somatotrophs, triggering cAMP-mediated GH synthesis and pulsatile secretion. Its trans-3-hexenoic acid N-terminal modification protects against DPP-IV degradation — the primary enzymatic pathway responsible for GHRH inactivation — thereby extending plasma half-life relative to endogenous GHRH.
A significant area of preclinical research on Tesamorelin involves visceral fat reduction and lipid metabolism, an active focus of body-composition and metabolic research. Research has also examined its role in cognitive research models relevant to GH/IGF-1 axis activity in aging, an area of ongoing investigation.
