You should really just try it for yourself for a couple weeks and see if it helps.
Some people find it to be magic, for others it has little effect. I think it is going to depend a lot on how much protein your regular diet contains and how muscle intensive your rides are.
I keep some on hand and use it that way, but I find I do just as well on my recovery if I am simply consistent with my training and eating habits the latter of which are already fairly high protein.
