This ingrediant is found in jack3d, it hasnt got alot of research on it,
some say it's fine and some say it can have side effects and long term damage.
Personally, i loved jack3d, i stopped taking it only because i found myself relying on it too much and seemed to always be depressed and moody while i was on it.
Thoughts about Dimethylamylamine and jack3d in general?
