I like Jack3d because when it works, I go in the gym and I am focused on moving iron. But it just seems like its not as potent as it used to be? I have been taking it for 3 weeks now and before that it was about a year since I last took it. I am taking 4 scoops and I am not feeling anything. I dont want to take it and waste it if it isnt going to do anything.
Does anyone recommend something else that gets that focus going?
