Just got through my first "cycle" of Arimatest, and I have to say I noticed no real effects. Through the course I followed the directions, maintained my diet, activity level, sleep, basically everything stayed pretty much the same. I took this mainly because I was curious. I had taken a bottle of T-Bomb II about 2 months before and noticed some results with that. But with arimatest I noticed nothing. No change in mood, sex drive, strength, endurace, recovery, nothing. With that being said I also didn't get acne, irritability, did nothing to my digestion or appetite. So basically for me this didn't do anything. For others it may have more of an effect.
