Research Focus

Tesamorelin is a synthetic analogue of growth hormone-releasing hormone, built on the full 44-amino-acid sequence with a trans-3-hexenoic acid group added for stability. It acts on the growth hormone axis, stimulating the pituitary to release growth hormone and raising circulating IGF-1. Published research has examined its effect on visceral adipose tissue, body composition and lipid profile, and cognitive function in older adults.

Tesamorelin has been studied in human clinical trials and is approved by the FDA as Egrifta for HIV-associated lipodystrophy. Our summary of the published literature is here: Tesamorelin Dosage: What Studies Have Investigated.

Testing & Certificates of Analysis

Cartridges are filled from the same independently tested material as our powder vials — HPLC purity and mass-spectrometry identity, certified per batch and published on our lab results page.
