why are you using protein shakes? you trying to cut? replace that shit with food.
the only shake i see necessary is waxy maize in water PWO - followed by whey and water 20 minutes after that
the rest is a waste in my opinion, unless of course you are really pressed for time and like filling in nutritional gaps throughout the day then they are useful
syntrax nectar is delicious
no lie the best shaker bottle i've used is from GNC - it's called the blender bottle
they never leak and i shake the hell out of them
