Product Information
Tesamorelin | Stabilised GHRH Analogue — Research Grade
Tesamorelin is a synthetic analogue of GHRH in which a trans-3-hexenoic acid group is conjugated to the N-terminus to enhance metabolic stability. It is FDA-approved as Egrifta® for HIV-associated lipodystrophy, providing a robust clinical data foundation for further research.
Mechanism of Action
- Enhanced GHRH receptor binding — the hexenoic acid modification increases plasma half-life vs native GHRH
- GH pulse stimulation — preserves physiological pulsatility while increasing pulse amplitude
- Visceral fat reduction — Phase III RCTs demonstrated significant reduction in trunk fat vs placebo in lipodystrophy subjects
- IGF-1 normalisation — studied for restoration of IGF-1 levels in GH-deficient populations
Research Areas
Tesamorelin is studied in visceral adiposity, metabolic syndrome, cognitive function (IGF-1 CNS effects), and GH deficiency research. Clinical trial data from the EGRIFTA program provides an unusually strong evidence base.
For Research Use Only. Rainbow Peptide supplies Tesamorelin exclusively for in vitro and laboratory research purposes. Not for human or veterinary use.
