Nootropic cycling simply refers to the process of taking periodic breaks from using a particular nootropic. Cycling patterns can occur over the course of days, weeks, or even months. For example, you can take a nootropic for four days and then take a break for three days, or even have 3 weeks of use followed by one week off. Different patterns are recommended for different nootropics. Modern AlkaMe will tell you in advance if one of your recommended nootropics should be cycled, and advise the best course of action.
