Phosphagen Elite from EAS is a creatine and beta-alanine combination, essentially adding beta-alanine to the established Phosphagen creatine formula. That's a great idea since beta-alanine's effects (lactic acid buffering) complement creatine's effects (more muscular power) very well. Once you start training with Phosphagen Elite, you'll notice you can push out more reps and more sets at higher weights. But it's a caffeine free formula so Phosphagen Elite wont interfere with sleep if used in the evening. EAS has also done the right thing by preloading Phosphagen Elite with high glycemic carbs so you can mix this right into some cold water and hit the gym.
