NO2 or NOS Precursor-Anyone Tried Them
I recently purchased some NO2 (Arginine Alpha-Ketoglutarate, A-AKG). It is supposed to cause muscular growth enhancement by working as a growth enhancing hemodilator. More O2 is the theory behind it. It claims many good potential benefits. I bought it for quicker recovery in my PE workout routine. I also saw a product called NOS precursor sold on the net. Does anyone have experience or knowledge of these supplements? Thanks for any input.
