About this peptide

Pituitary GHRH signaling, not exogenous growth hormone.

Tesamorelin is a synthetic analog of growth hormone–releasing hormone (GHRH) with a trans-3-hexenoic acid modification that extends half-life — studied for its ability to stimulate endogenous GH release from the pituitary and reduce visceral adipose tissue in clinical research.

It is not FDA-approved for medical use. Natura ships it as a batch-verified research pen so you can dial a consistent dose and read the lab paperwork before you open the box.
