L-glutamine vc Glutamine Alpha-Ketoglutarate

[eaglecall]

Is there really an advantage on glut AKG? TN says that with this you only need to use one fifth of L-glutamine to obtain same results. Is that true? Just wondering whats best for the money while of course achieving the same objective. I wouldnt mind using less powder since 10g of glutamine pretty much fills up the whole bottle.
