Just in case any of you are interested in purchasing this product... I have been taking this product for about 3 weeks now.. At first, I hated the taste. Tastes like medicine or crushed vitamins.. After awhile, I wouldn't say that I necessarily liked it, but it wasn't bad at all and I didn't mind it. (You can sip on this just fine.) It mixes pretty decently.. I mean, it's got BCAA's so those don't mix well, but what BCAA product mixes 100%? I like to shake it each time I'm about to take a sip cause sometimes shit settles at the bottom.. but overall, this stuff mixes well. The beta-alanine can cause a tingling sensation too.. At first this takes a little getting used to.. it's weird. Feels like pins and needles sometimes, and other times feels like dry skin. It's probably just a thing in my head but I feel like when I push harder while doing cardio, the sensation goes away.. so it definitely gives you some motivation to finish your cardio too. Haha.. Now, the important part, the performance.. I LOVE THIS STUFF! Caffeine has never really affected me before.. I mean, I've tried pure caffeine tablets, AMP, Stimulant X (all of these were samples) and I've even tried messing with the dosages as well as cycling the stuff. I've taken up to 6 caps of AMP and didn't feel SHIT. When I take 3 caps of AMP and two scoops of Purple Wraath my energy levels go through the roof. Cardio is a breeze.. doing +40min cardio is like taking a walk. I've taken Xtend before (went through about 1 1/2 tubs) and I didn't feel nearly the same as I do when I take Purple Wraath. Yes, I've tried the Xtend and AMP combo.. still didn't have the same effect as my Purple Wraath/AMP combo though.. Also, I don't know if it's an effect from the product or not, but after I get done doing cardio I have a ton of energy and am in a great mood -- always. This usually isn't the case for me and I have only noticed this since I started taking PW. CLIFFS: For those of you cutting or doing a lot of cardio, I definitely back this product. I like it better than Xtend and if you need a pick-me-up while doing cardio, try taking it with some AMP.
