How long does Epitalon take to work?
In the first week of Epitalon, sleep architecture often shifts within days. Around week 4, pulse usually complete by this point. By week 8, off-cycle. Effects, if any, are subtle and long-tail. Response varies between people, this is the commonly reported pattern, not a guarantee.
