Probably a dumb question , but all we know that some PH are methylated to elude degradation, so protein couldn't be methylated too??

Hydrolyzed protein is the fast absorbing protein. Protein "breaks" into Aminoacids. So, if we want the fastest protein posible (for intra-workout, for example), then the best would be Methylated-Hydrolyzed-Aminos :think:

What part of the AA do you propose methylating? Methyl esters could release toxic methanol. This came up some time ago with creatine methyl ester, which is why CEE replaced it.

Aren't FAA's or hydro-whey fast enough?

Then you'd have a liver toxic food source. You may be onto something.

Methylated does not equate with liver toxicity. This only applies in the case of C-17AA steroids.
