I wasn't really lifting while i was on this. I had high blood pressure at the time and was taking it easy. I was using it more so for recovery. But my muscles felt pretty full while i was on it and the workouts i did have went pretty well.
I think BBB and a few others on here have used this product before or the kilo sport version "attack" and have had good results in the gym.
surprisingly though, my libido was not very good on this. I'm assuming its because it lowers estradiol levels so low. But as far as size and strength gains from this products, most people are giving it 2 thumbs up.
