Cool study...
To sum it up for people....
A combo of whey and casein is best
From reading the study I would still stick with my PWO shake and reccomendations to anyone who can use Milk to do so
I reccomend eating a real food meal 45mins to 1hr after ur PWO shake aswell
If u could not eat in this time, make sure you utalise a good source of casein (casein powder) rather than relying on milk casein to keep u going,, as GB does
Thanks for the link
