Great satisfaction. I haven't had such a good workout in a long time. Gradual slower ramp up, but for an hour I felt immortal :D No bloating or nausea. I'd knock off half a star for the flavour - you don't get much enjoyment out of this one.
It prepared me quite well for the workout, I could feel the beta alanine and I'm quite used to it, I dare say. As for the taste, it's not sour, but it has that unpleasant "dry" tail, nothing you can't drink but I don't drink it with taste. I'm using it up, but I don't think I'll order it again.
It delivers what it promises, the taste and solubility is good. Only the recommended dosage for a 50 kg woman is a bit too much, so girls beware :-D
