How long does Amycretin take to work?
In the first week of Amycretin, appetite drops. Some early-trial users reported faster onset than Semaglutide alone. Around week 4, first titration step. By week 8, phase 1b data showed weight loss outperforming Semaglutide-monotherapy comparators. Response varies between people, this is the commonly reported pattern, not a guarantee.
