Ipamorelin works by binding to IGF-1 receptors in the body and mimicking its effects on those receptors
Its defining pharmacological characteristic relative to its predecessors (GHRP-2, GHRP-6) is its selectivity: at doses exceeding 200-fold the GH-release ED, ipamorelin does not stimulate significant release of adrenocorticotropic hormone (ACTH), cortisol, prolactin, FSH, LH, or TSH, in animal studies
Conversely, if the glutathione production process (or the trans-sulfuration pathway) is not functioning properly, the process backs up and homocysteine levels accumulate putting additional strain on the methylation cycle to remove it

Semaglutide and tirzepatide bind to the same receptor as GLP-1 and cause a similar action, which, in this case, helps manage normal insulin and blood glucose metabolism
