Comparing Tesamorelin and Ipamorelin

Tesamorelin and Ipamorelin are both growth hormone-releasing peptides, but they have different mechanisms of action. Tesamorelin specifically targets the release of growth hormone from the pituitary gland, while Ipamorelin stimulates the production of growth hormone throughout the body. These differences can influence their effects and potential side effects. There may not be sufficient evidence to answer exactly as the provided articles do not contain information about Tesamorelin. Please refer to reliable medical sources or consult a healthcare professional for accurate information about Tesamorelin.

What is Tesamorelin?

Tesamorelin is a synthetic molecule, which can be used as a substitute for human growth hormone releasing factor (GFR). GFR stimulates the synthesis and release of endogenous growth hormone.

Tesamorelin has been developed as a potential treatment for a variety of conditions related to the deficiency of growth hormone, including HIV-related lipodystrophy [1].

So far, tesamorelin is the only treatment which can reduce the excess abdominal fat in patients with HIV-associated lipodystrophy [2]. It also seems to significantly decrease waist circumference and visceral adipose tissue [3]

In addition to these, tesamorelin seems to reduce liver fat and prevent fibrosis progression in HIV-associated non-alcoholic fatty liver disease (NAFLD) [4].

However, tesamorelin has some side effects including injection-site reactions and common side effects associated with growth hormone therapy for instance headache, peripheral edema or arthralgia (joint stiffness) [2].
