Ahhhh you've bought into the GNC hypnohype. Unless you are an elite athlete, there is no need to alter molecular repair times with silly things like specialized food products and ice baths; the body already has a pretty good system in place, and chances are the op already consumes enough protein.

Something your missing in this equation is blood flow, which is just as important in recovery as it is the vehicle which enables the recovery process. Slamming a protein shake (bro, do you even lift?), if anything, hampers recovery somehwat by stimulating the vessels around the GI tract which effectively takes some blood flow away from the sight of recovery. Just resume an adequate diet and you'll be fine; there's no evidence to suggest that normal people like you and I actually benefit from a recovery protein shake. Feel free to link an academic journal if you disagree.

I ride my arse off to work and back all week, and I feel no discernible difference in recovery time whether my post-ride consumption consists of a granola bar, a protein shake, a greasy breakfast burrito or just a cup of coffee. I'll tell you what does make a difference - walking around the block on my breaks and drinking 3-4 liters of water between my am and pm rides.
