Impressive, expensive.
Extremely potent. I wish it did not cost as much. I have ultimately chosen to take a half dose, because the effects are profound and have a noticeable (to myself and others) effect on my personality/affect and disposition (restless, distant, easily engulfed in tasks, absent-minded socially). Perfect for taking if you anticipate being absorbed in a single task, not so much if you plan on being social.
