To be honest i dont go directly after. i finish work at 5:30-6 then hit the gym at about 8:30. gives me time to have a littel rest and get some food into me before i go. What pre workout do you use? I used to be a big Jack3d fan before they had to change the formula. I'm currently using Muscle Pharm Assault for the first time. Pretty good, very similar to Black Powder I've found... Not the biggest fan but it does the trick
