Tesamorelin — Research Use Only
Tesamorelin is a synthetic 44-amino-acid analog of human growth hormone–releasing hormone, also known as growth hormone–releasing factor. The molecule contains the complete human GHRH(1–44) sequence with an N-terminal trans-3-hexenoyl modification designed to increase stability against enzymatic degradation.
Tesamorelin is used in qualified research settings to investigate GHRH-receptor signaling, pulsatile growth-hormone secretion, IGF-1 pathways, adipocyte biology, lipid metabolism, and body-composition measurements in defined experimental models.

Important Regulatory Distinction
Tesamorelin is the active ingredient in the FDA-approved prescription products EGRIFTA SV and EGRIFTA WR, which are indicated to reduce excess abdominal fat in adults with HIV-associated lipodystrophy. The prescribing information specifically states that these products are not indicated for general weight-loss management.
The tesamorelin offered by Pep Research Labs is an independent research-use-only material. It is not EGRIFTA, is not an FDA-approved drug product, and must not be represented as equivalent or interchangeable with either approved prescription formulation.
