Nothing compares to the focus I got and still get from JP8. Everyone I've let try it agrees. Honestly, I get better pumps/more endurance from other products, but bar none, this stuff gives me laser-like focus and drive. I'll stack it with Nos Ether for that. No crash for me after either. For me, I use nearly 1 scoop. JP8 is not your candy tasting pre-workout, and I'm fine with that. I'm using it for the results, not the taste. I do add a bit of grape juice to mine though. I'd try them both if you can, wouldn't hurt.
