I am not on any suppliments or gear. The only thing I have taken is Amp 02. I started with 6 pills, then tried 8, and then tried 10. I usually take 8, and on occasion I take 10. If you have ordered a bottle, work through the entire bottle. If at the end, you don't think it's worth it, never order it again. That's what I would do.
Are you taking anything else that might be affecting your workouts? Have you changed anything lately (Eating habbits, sleeping habbits, stress, work-out times, work out exercises etc)? Just curious. Thanks and good luck
