Its great for increasing strength....although... no more than 30mg for not more than 3 weeks. 20mg ED is about right for 3 maybe 4 weeks. After 3 weeks you will find you feel a bit sluggish. Basically because it is very toxic. The only way around it drinking tons of water, but you will still feel sluggish after the 3 weeks...maybe sooner. Drinking at all on this will quicken the onset of sluggishness and really make you feel like crap.
