Angiogenesis Mechanisms and Blood Vessel Modeling The pentadecapeptide component actively stimulates pathways responsible for angiogenesis, which scientists define as the formation of new blood vessels
In a systematic review of 10 clinical trials in patients with HIV lipodystrophy, tesamorelin was effective in reducing VAT and increasing lean body mass and did not alter subcutaneous adipose tissue (146), and increased GH and IGF-I while insulin and glucose levels are unchanged indicating preservation of insulin sensitivity (147150) ( Table 1 )
