I was reading up on nitric oxide products. Right now I have whey,casien,and creantine is all I take and since im young 19 almost 20 prolbally dont need a test booster. So i was thinknig of a nitric oxide supplement. What are the benefits. so far i read that it will make you muscle look bigger and fuller all day. I read abotu BSN nitrixx it also said it can make u larger down below is that true? What is the best nitric oxide supp out there? Or should i take soemthing else instead?
