i would have to say take the hawthrone berry
i was having bad lethargy attacks, on this stuff, would go black and white.
and had to quite my workouts short, but that hawthorne berry helped big time.
Legally yes. But it really depends on how long you have been training and how educated you are. If you are asking this question then I would say that it is probally not a good idea for you to do a cycle.
