First I want to say I've tried mostly every PES product and had good results. I also bought this bottle with my own money but I need to share my experience.
Taste: I had fruit punch and it's pretty bad. It's drinkable because 4-5oz of water is nothing. But this stuff is tart and chemically tasting. Maybe the raspberry is better but this isn't one of the top fruit punch product.
Mixability: Doesn't mix very well at all. I find myself pouring in a bit more water each time to makre sure I get everything that stuck to the glass. The powder is thin enough though that you don't choke on it when you drink it which is good.
Energy: Nil, I always read how people love the energy from Alphamine and use it preworkout. But this stuff gave me no clean energy at all. I could take Alphamine and fall asleep if I have to. However what I did notice was jitters and shakes. The stuff felt soo unclean almost every time I took it. Like this morning I was brushing my teeth and my hands were shaking. Thats not good in my book. Unless you count that as energy but it wasn't like the rush of energy I expected.
Thermo: This was a toss up for me. The morning dose didn't do anything in terms of thermo effects. But the afternoon dose which is also my preworkout helped me break into a sweat a lot faster than usual which was the biggest plus that Alphamine offered. Just after warming up I noticed I'd be sweating like I was half way through my workout.
Needless to say I was disapointed with this product. I've heard tons of positive reviews from it and even recommended Alphamine to friends based on those reviews. But I can't recommend it anymore after trying it myself. It's not what I thought it would be. PES missed its mark with this product.
I almost forgot. Alphamine gave me some g.i. issues as well. That doesn't really bother me and I don't get upset about it but for anyone who gives that kind of thing a thumbs down.
