I've used it. I'm about to start back soon enough on it. I really don't know why I haven't yet. Anyway.....
Great Product. Don't get the grape, but the Lemon Lime flavor is cool.
Strength gains were good. I got all "intense" in the weight room. I can't really explain that one at all. The pumps were amazing, but pumps are just pumps.
So, go for it bro. I really like the product. I did a little write up on this board a while back. MAybe you can find it. Good Luck.
