I have been taking Superpump and No-Explode for quite some time now. Problem is I'm thinking it's gotta be bad if your body get's use to only working out on these stimulants. Pluss I get the crazy gas upset stomach, pluss the stomach rot after I work out, Wondering if it's possible to get better pumps and better lifts without the stims. If anyone body builds stimulant free. I'm currently trying to get my body off the stim's no caffeine etc just getting the head ache's and the withdrawel symptoms. I guess I'm just wondering if anyone out the work's out without the stims, like now when I go to the gym and I don't take the superpump I just feel so week wondering how long this takes for my body too feel back to normal.
