I am 22 years old and have worked out for many years. Have low body fat and muscle mass is ok, just wanna try it out anyway 
I am wondering how much to take though? I dont need a massive increase, but still wanna see a difference. Would be great if I could avoid the side effects too..
So.. how much and how often?
Appreciate all the help I can get..
