if anything, i'd add BCAA in lieu of glutamine after hard workouts. hard defined as anything requiring me to spend a lot of time above threshold. back when i was racing, 16 fluid ounce of kefir was what I took
the other thing is, that's a lot of protein in one go. someone probably knows this a lot better than I do, but can you be sure that all of it will be utilized as amino acid for muscle repair (cf. metabolized)?
