I didn't change anything in my diet or activities, so everything should be related to the product. I didn't get blood work so I have no idea if it changed my test levels, decreased my estrogen. Sexual wise, I don't see that it changed my, as my libido is already very active. My lifts and recovery did increase. I haven't documented those in a long time, but I know the numbers in my head. I did feel more of a drive in the gym. I feel also at 4 tablets a day my aggression was increased. I am usually pretty calm and laid back, but I did have to yell aggressively at an employee for a stupid act. Face went red, and hot, I started shaking it was insane.
