Product Name:
Tesamorelin Acetate
CAS Number:
Tesamorelin acetate is a synthetic analogue of human hypothalamic Growth Hormone Releasing Factor (hGRF) indicated to induce and maintain a reduction of excess abdominal fat in HIV-infected patients with lipodystrophy.
Mode of Action:

By acting on the pituitary cells in the brain, tesamorelin stimulates production and release of the endogenous hormone (hGRF). Tesamorelin therapy predisposes the patient to glucose intolerance and can also increase the risk of type 2 diabetes, so the drug is contraindicated in pregnancy.


Tesamorelin stimulates growth hormone secretion, and subsequently increases IGF-1 and IGFBP-3 levels.


No formal metabolism studies have been performed in humans.


Diarrhea, congestive heart failure, peripheral neuropathy, and loss of mobility were the four serious adverse events reported during the clinical studies
