Both peptides show reduced GH release with repeated dosing (tachyphylaxis), though the time course differs between compounds
For analytical testing, this means: RP-HPLC and LC-MS/MS methods developed and validated against Novo Nordisks recombinant semaglutide reference standards may not fully characterize impurities in synthetically produced samples, and vice versa
