After getting this question enough, I decided to publish a quick article that details some of the points about chocolate milk as a recovery drink. Regarding your questions about the supplements that you would be missing out on by not going with the P90X drink; I can’t see any issues with adding creatine and L-glutamine to milk (I can’t speak on the arganine at this point). As for the B-complex, you should be getting enough of that from your daily vitamin and I don’t perceive any benefit with it being tied to the mix.

Check GNC or Amazon.com for amino acid powder or amino acid liquid supplements.

I have heard that Skim Chocolate Milk is an excellent recovery drink, and probably the cheapest available. It lacks the dose of creatine, l-glutamine and arganine that is in the P90X drink, as well as the vitamins. So 2 questions, do you recommend skim chocolate milk as a cheap alternative that has the 4:1 ratio, and so could/should you add a b-complex vitamin and modest hit of those amino acids to it? If so, where can you find the amino acid powders to supplement the milk?

Thanks,
