Beta Alaline, how much?

I was wondering how much Beta Alaline I should be taking a day. The product I bought says 2 grams a day. Though I've heard 5 grams is somewhat standard.

I took 5gr today, but I got the tingling sensation which isn't very nice but not too uncomfertable as it eases away quite rapidly. And after a couple of days it works rather good to my surprise. I've always had a problem with lactic acid, but this stuff somehow made it disappear.

But 5 grams overkill?

5 grams is the perfect amount IMO.. I've done 10 grams pre workout and notice no difference from ten to five...I also run 5 grams arginine pre workout gives insane pumps...your good to go..that tingling feeling is awesome..lol...I love it..

Makes the hairs on my body stand up... Walk round the gym scratching like some junky. haha
