go get some protein, creatine (any will do), fish oil, and multi vitamins. and your question on NO, NO2, NOS all the same stuff but you don't need that right now. that just gives you some cut and your vains show more. if i were you i'd just take the NOS during your cut? but at 6'1 190 thats isn't all that big... you said you have some "meat" just eat right, lift heavy, rest and repeat your meaty section will turn into muslces in no time. during your first month or two you'll gain up to 10-15lb? well for me at least. just stick to it with dedication. good luck oh stop going to gnc their just wanting you to buy the more expensive things because their base commission. (i use to work ther) lol. the only thing i get there are the whay because anything else just makes me gag.
