The whole stupid ass “30g at a time” thing is based on the spike to MPS (and that assumes that the 30g consists of nigh perfect ratios of needed amino acids). As has been shown multiple times, MPS is a stupid fucking endpoint metric, because your body uses amino acids for thousands of biological functions.
Knowing how the body tends to do things in the adaptation realm, for people who are constantly resistance training and recovering from it, MPS is not going to be the final endpoint anyway, so coming up short on protein will have you coming up short in some enzymatic processes and the like. I wouldn’t go so far as to speculate that the body will ignore replacement for organ cell turnover in favor of MPS in hard training individuals, but I wouldn’t be shocked if it ended up being the case.
