Tesamorelin
Tesamorelin is a synthetic analogue of endogenous growth hormone-releasing hormone (GHRH) consisting of the full 44 amino acid sequence stabilised by a trans-3-hexenoic acid group. Widely used in growth hormone secretion and body composition research. Supplied as lyophilized powder with batch-specific COA.
About Tesamorelin
Tesamorelin is a synthetic form of growth hormone-releasing hormone (GHRH) in which the entire 44 amino acid sequence is conjugated to a trans-3-hexenoic acid group, improving stability compared to native GHRH. It binds and activates the GHRH receptor to stimulate pulsatile secretion of endogenous growth hormone from the pituitary.
As a research compound, Tesamorelin is of interest across multiple areas including GH axis pharmacology, metabolic studies, and body composition research. Supplied as lyophilized powder for maximum stability and research flexibility.
Research applications
- Growth hormone axis and GHRH receptor studies
- Metabolic and body composition research
- Comparative GHRH analogue activity
- In-vitro receptor pharmacology
- Pituitary cell biology
