Daa and Erase worked wonders for me.... I think you need to read and stop being some self centered prick. You do realize estrogen plays a huge role in our body's libido and other systems. IF you dip to low then bye bye libido which happened to me at 3 caps of Erase per day. DAA has undergone many peer reviewed studies but the true fact of it is that not everyone responds to supplementation the same way other people do. For example someone with a high tolerance to caffeine may need two scoops of a PWO instead of 1 I wish I was one of those people lol.
