| Tesamorelin (usan) consists of the 44 amino acid sequence of human growth hormone releasing factor (GRF), with a 3-hexenoyl group attached to its tyrosine N-terminal residue. It is a new growth hormone releasing factor analogue, which can not only restore normal growth hormone secretion in the body, but also reduce the increased visceral adipose tissue (VAT), improve blood lipid abnormalities and quality of life, and maintain glucose homeostasis in the body. |
Tesamorelin is a synthetic growth hormone releasing hormone analogue used in the treatment of visceral adiposity in human immunodeficiency virus (HIV) infected patients with lipodystrophy. Tesamorelin is given subcutaneously and has major effects on glucose and lipid metabolism, but has not been linked to serum aminotransferase elevations during therapy or to instances of clinically apparent acute liver injury.

What is tesamorelin peptide used for?
Tesamorelin is a synthetic growth hormone releasing hormone analogue used in the treatment of visceral adiposity in human immunodeficiency virus (HIV) infected patients with lipodystrophy.
Does tesamorelin increase muscle mass?
Conclusions: Among those with clinically significant decrease in visceral adipose tissue on treatment, tesamorelin was effective in increasing skeletal muscle area and density.
How long does it take for tesamorelin to start working?
Studies showed that people being treated with Egrifta SV (tesamorelin) had lower belly fat after 26 weeks of treatment compared with people who weren't receiving the medication. If you've been on Egrifta SV (tesamorelin) for 26 weeks and haven't noticed a change in your belly fat, talk to your healthcare provider.
How often do you inject tesamorelin?
Inject this medication under the skin on your stomach (abdomen) as directed by your doctor, usually once daily. To help you remember, use it at the same time each day. Pick an injection site that is below your belly button to the left or right. Avoid any area with scar tissue, bruises, reddening, or irritation.
How effective is tesamorelin?
Conclusions: Tesamorelin reduces visceral fat by approximately 18% and improves body image distress in HIV-infected patients with central fat accumulation. These changes are achieved without significant side effects or perturbation of glucose.
Do you need a prescription for tesamorelin?
It is used to reduce excess fat (lipodystrophy) in the abdomen or stomach in patients infected with human immunodeficiency virus (HIV). This medicine is available only with your doctor's prescription. This product is available in the following dosage forms: Powder for Solution.
What peptides increase testosterone levels?
MK-677, known for its growth hormone-releasing effects, may increase testosterone through the elevation of insulin-like growth factor 1 (IGF-1). Ipamorelin, another growth hormone-releasing peptide, stimulates growth hormone production and IGF-1, supporting testosterone production.
