should i stack nitric oxide, protein, creatine, and oxyelite pro?!

That's not bad, minus the creatine...I PERSONALLY do not recommend it..just because you have to cycle on and off of it. And the mass you get from creatine is all water. When you cycle off creatine, you will lose soo much mass. And that is discouraging. Otherwise, i recommend the rest of the stack.

I recommend staying away from oxy elite simply because it's bad for your heart, BUT nitric oxide is good for strength gains and that sexy vascularity. Don't take more than 14g creatine per week unless you want to gain 10 lbs of water only to piss it out days after you off cycle creatine. Protein take anytime you want, just check the additives. The danger of taking oxy elite with nitric oxide is both ramp up your heart rate and increase blood pressure. I would either take oxy elite OR N.O. Not both.

I once went to a doc appointment after a workout with Black Powder, my blood pressure was 190/115! The highest it's ever been. My doc thought the nurse made an error but it was crazy high. I stopped taking Black Powder but I still take L-arginine, l-glutamine, L-histidine, L-norvaline and other amino acids that help with nitric oxide production.
