Been taking ash for almost a year now. Definitely more fluent then I ever have been. Looking to add L-theinine. Anyways You do build up a tolerance to ashwaganda so I cycle off every couple months or so. And make sure you get a good source lots of trash out there just do your research i won't recommend any brand in particular but stay away from the really cheap one on Amazon that claims its 3000mg and don't even start that high go with 300 or 600mg max
