"Ripped Fuel 5X seems to work for me. I've gone through a good portion of the bottle, and I suppose it works.. but not in any way I would call effective. The most notable effects I had were:
1. Seriously unfocused. I'd take the pill in the morning and I'd be in a daze for, literally, several hours. It didn't give me any energy, and reduced my focus, not enhanced it.
2. Lessened appetite. I did notice this effect, and it wasn't bad.
3. Odd feeling in the chest. It felt like my heart rate was spiking and lowering on the days I took Ripped Fuel, even if I was just sitting down relaxing. Didn't like the feeling, could continue to feel it if I laid down to sleep or take a nap.
4. Minimal fat-loss. I noticed it did trim a bit, but I wouldn't consider it to be remotely of the same caliber as Arson, Hydroxicut Hardcore, Redline, or various other products.
All in all? I suppose if you're already lean and you really want to just shave off a tiny bit of stubborn fat, it might work. It cut a bit off for me, but not as much as I would like. Wouldn't recommend, and wouldn't suggest for someone looking for a serious product though. Good for beginners."
