URep, i'm following your lead brother. I've seen many questions like this lately and concerning nitro.
"You really can't compare whey protein and Animal Nitro. You would use each for different reasons. Whey provides basic aminos needed by the body to function properly. In this way, whey is a general supplement. Animal Nitro, on the other hand, is a very targeted supplement. Animal Nitro is more efficient and it can help promote anabolism. It should be used pre- and post-training specifically (though it can also be used throughout the day). According to some unpublished results, researchers noted that essential amino acids were incorporated into protein, not catabolized. On the other hand, when 40g of whey protein was ingested, urea production increased significantly. Urea is the chief nitrogenous waste of mammals. In short, a lot of whey protein can ultimately turn into a waste product, urea, whereas essential aminos are used by the body. Efficiency is one difference. The other main difference is that essential aminos in 'uncoupled' forms can exert specific pharmacological and physiological benefits."
You can also find LOTS of other good Nitro info here:
