I just got a 4.5kg tub of the choc flavour from A1 supps today. I think its a pretty good powder. has added bcaa's, added creatine, and taurine is in the ingredients listing. doesnt say how much of each of these things is in each serve though. But its a pretty good powder imo.
Btw shrek, it gives an absorbtion time chart for each of the different proteins.
bcaa's-40minsapprox
WPI-1hr
WPC-2hrs
Milk protein isolates-3hrs
Micellar Casein-4hrs
