L-Glutamine powder Which is the best?

Which is best powder? I am going to dissolve it into a shake ED.

I use the optimum nutrition brand and it dissolves well in my shakes.

glutamine peptide(sp?) better absorbtion over regular L-glutamine

I use either opitimum or prolab..haven't had a problem with either of them.

I've been using Prolab and have no complaints...

I like prolab, I have tried a few others and they are always gritty.

Pain

I use MHPs and its the shit

i use max muscle's L glutamine powder...take scoopfull in my mouth then wash it down with water. Doesn't taste bad either.
