I've generally had great results with Alpha Male. There is no need for PCT with Alpha Male. I recommend Rez-V as an all around health supplement. I've had blood work done while taking Rez-V and it my E2 levels are lower, and test slightly higher. I haven't had blood work done with Alpha Male, but I certainly 'feel' a difference after about a week or two.
Also, if you're not at least 25 I doubt Alpha Male will do anything for you except maybe increase libido.
Hope this helps.
