A synthetic GHRH analog studied for pituitary GH-axis stimulation in laboratory and clinical research settings.
Research use only. Not for human or veterinary use.

Tesamorelin
10 MG
Overview
Tesamorelin is a 44-residue analog of growth-hormone-releasing hormone with an N-terminal trans-3-hexenoyl modification described in the medicinal-chemistry literature. Papers evaluate GH and IGF-1 responses and body-composition endpoints in regulated studies. This catalog item is a research peptide with lot documentation, not a prescription product and not a personal protocol.
Research areas
Framed as published laboratory and clinical literature. Not treatment guidance.
Pituitary GH-axis assays
Receptor and explant studies examine GHRH receptor activation and downstream GH release in controlled laboratory systems.
Body-composition research
Clinical publications report visceral adipose and lipid measures under investigational or labeled drug use. Those data do not authorize consumer use of research vials.
