I was using s4 100mg ed. 50mg 2x a day it's very fast acting you can notice the effects within about a half hour. You have increased energy muscle hardness and you appetite is through the roof. I couldn't get enough food which is why I stopped using it to save it for a later time. I was gaining weight but not the type I wanted to gain basically my diet was and still is terrible.
There's allot pf people trying it right now, theres logs all over at ol
