You guys are all saying that your workouts are going downhill since you stopped using Amp 02? Thats not good. I am not going to claim to be an expert in any field regarding weight lifting, but, I have been taking no xplode and have been lifting on and off for some years now. Seems like people have withdrawl symptons from Amp 02, almost seems like a friendly version of cocaine. LOL, these pre work out supps are more in the head than anything else. All it does is give you energy so you feel more AMPED up to work out. Healthy eating habbits, water, sleep and healthy mental life through relationships/work/school should give you all the energy you need to lift. I take no xplode but im not sure its the best thing for me. All im doing is forcing my energy levels up so i can PUMP PUMP PUMP and then i kinda crash later in the day. I think the best pre work out supplement is a healthy lifestyle and anything else is (like no xplode, shotgun, lipoflame, ampo2) is just a really really good version of sugarfree redbull or something. Whats my overall opinion? Terrible habbit to rely on prework out supplements to have a good workout. What are we gonna do, take high ammounts of heavily concentrated caffeine before every work out for the rest of our lives? If we do that, I can assure you that the rest of our lives for working out won't be as long or as healthy as we all may wish. All these pre work out supps do is allow us to be lazy in other areas of health. We won't eat like we should, feel like we should, and to solve it all we just take amp02 for the energy before workouts and feel tottaly fine with it. Doesn't that seem to atleast 1 out of 10 people on these forums to be a (for lack of better words) bad?
