Tesamorelin is a synthetic growth hormone-releasing hormone (GHRH) analog. It was based on the 44 amino acids sequence of GHRH and contains a trans-3 hexenoic group to protect it from enzymatic degradation. These modifications allow it to be more stable and have a longer half-life.
Just like Sermorelin, Ipamorelin or GHRP-2, Tesamorelin is considered a growth hormone secretagogue (GHS) which stimulates the secretion of GH and increases the level of insulin-like growth factor (IGF-1). The importance of IGF-1 is it tends to be lower in patients with obesity, diabetes and especially in those with lipodystrophy.
