44-amino-acid GHRH analog with an N-terminal modification that resists enzymatic breakdown — used in research with longer in vitro stability than Sermorelin.

Tesamorelin is a 44-amino-acid synthetic GHRH analog. Compared to Sermorelin (which is short and quickly broken down), Tesamorelin has both a longer sequence and a chemical tag (trans-3-hexenoyl) on its front end that blocks the DPP-4 enzyme — the one that normally chops up GHRH peptides quickly. The result: a much more stable research tool.
How it's been studied: Lab research has examined how Tesamorelin engages the GHRH receptor with significantly longer in vitro half-life than natural GHRH, and how that stability changes the dynamics of growth-hormone-releasing signals in pituitary cells.
Where you'll see it in research:
Handling notes: The N-terminal modification blocks DPP-4 cleavage, so reconstituted solutions are notably more stable than Sermorelin's.
