A: Tesamorelin is a synthetic analog of growth hormone-releasing hormone (GHRH) with a trans-3-hexenoic acid modification that increases stability. It is the only GHRH analog with FDA approval (as Egrifta) for reducing visceral adipose tissue in HIV-associated lipodystrophy. Q: How does Tesamorelin stimulate growth hormone? A: Tesamorelin binds the GHRH receptor on anterior pituitary somatotroph cells, stimulating pulsatile GH release that preserves the natural diurnal secretion pattern. Unlike exogenous GH, it maintains feedback regulation and does not suppress endogenous GH production. Q: What has Tesamorelin been studied for beyond HIV lipodystrophy? A: Research has explored Tesamorelin for cognitive function in aging (GHRH-GH-IGF-1 axis and neuroplasticity), general visceral adiposity reduction, metabolic syndrome markers, and as a tool for studying pulsatile GH secretion physiology. ## Interactive Tools - Research Calculator: https://tesamorelin-research.com/tools/dosing-calculator/ 88+ peptide protocols with reconstitution calculator, dosing phases, mechanism of action, half-life data, administration guidance, side effects, compatible stacks, per-protocol FAQs, and interactive syringe visualization.
