So obviously one of the most common reasons AAS' are used is the increase in protein synthesis, that provides faster muscle gains.

My question is regarding other amino acids that play a large role in brain activity. IE, Phenylalanine, tryptophan ect.ect.

Will these aminos be more readily available and easily used by the brain while on AAS therefor increasing the supplements effectiveness?

FOr example if I where to go by some 5-htp and use it while on AAS, would the brain use the supplement better, or is protein synthesis only increased for the muscles.

I hope im making sense on what I am trying to ask.
