Tesamorelin + ipamorelin work through complementary GH-release mechanisms: tesamorelin activates GHRH receptors on pituitary somatotrophs, while ipamorelin selectively stimulates ghrelin receptors without cortisol or prolactin elevation
Interestingly, some people on GLP-1 medications report symptoms that mimic the early stages of a cold or the flu
Semaglutide produced less weight loss than tirzepatide head-to-head, about 14% versus 20%.
