i work at gnc in ross park mall 1 day am month for the discount. no2 black costs $125 for the large bottle, nano x9 is around 79.99, nitrix is 89.99 for 420 pills…i get a discount,i don’t like ordering supplements online.
and there are a lot of reviews that also show the effectiveness of the l-arginine used in no2 products. l-arginine was mostly used in over the counter erectile disfunction pills, and when more studies were done with arginine, it was proven that it increases bloodflow through the whole body.
i am using altered state, no-xlode, cell mass, ce2, off-cycle, for my main supplements right now. i am also using aminos and thermogenics.
