Sounds good, right? BUT. This is still a hypothesis that's based on acute (immediate-effect, not long-term) and infusion (intravenous) data. We're looking at circumstantial bits & pieces, not a complete picture. This research did not measure effects on size, strength, or muscle retention over the long term. At best, this data is hypothesis-generating, and far from conclusive. Also keep in mind that the literature cited (Bohe et al, 2003) has some fricking hilarious stuff in its conclusion. I'll quote them:
"it appears that only modest amounts of dietary amino acids would be needed to achieve maximal stimulation of the muscle anabolic processes (i.e. for adults of average weight, 55-75 kg, 0.260 mg kg/hr x 2 hr, or of the order of 30-40 g of protein). This is probably somewhat lower than the current FAO/WHO/UNU recommendation of 0.8 g kg/day and much lower than that of 1.2 g kg/day proposed by some workers for the elderly (Campbell et al. 2001)."
^^Check the bold. Bohe et al, who ALWAYS get referenced by the proponents of BCAA dosing in order to avoid the refractory response, don't even have their heads screwed on tightly regarding total protein needs.
