Given that, in isolation, BCAA administration resulted in lowered non-BCAA amino acid precursor levels (including tyrosine, tryptophan, etc.) in the brain--and hence reduced production of DA, 5HT, etc.--is there any evidence of the benefits of acute administration?
I'm not talking about long-term megadosing of scivation and the like. Whereas a constantly lowered precursor environment could negatively affect cognition/arousal, etc., a planned schedule of acute administration might have the effect of upregulating certain receptors, to beneficial effect.
I've not had the time to really seriously read through many research articles, so this is speculative. I know there are links between BCAA consumption and mood, and while there is debate about the effects, it's generally about the acute effects. I'm concerned with longer-term effects of acute administration, not vice versa.
Any input would be appreciated.
