Melanotan II acts as a non-selective agonist with nanomolar-range affinity at MC1R, MC3R, MC4R, and MC5R, with relative potencies varying by assay system but generally showing highest functional activity at MC1R and MC4R in cAMP accumulation assays using transfected cell lines
Some health benefit plans cover weight loss injections like Wegovy, Saxenda (liraglutide), and Zepbound (tirzepatide)
The overall mechanisms by which GLP-1RAs carry out their cardiometabolic effects are still unclear, however recent studies suggest that this process may be mediated by reduction of inflammation and epicardial adipose tissue [42, 43]
The FDA prescribing information for Wegovy (semaglutide) reports musculoskeletal painincluding back pain and extremity painas possible side effects, as does the prescribing information for Zepbound (tirzepatide)
