Wow, thanks everyone for your interest/concern. I am prescribed adderall. I get the 10 mg's not time released. I only take half before workout just for that extra little push. I was just concerned with mixing addy and an NO product as I was not aware addy was a vasoconstrictor. Its just that I like that extra stamina I have in the gym on the addy and was thinking I could use a little extra pump from the NO supp. I feel like I have reached yet another plateau and was thinking maybe the NO product could give me a little push. I don't want creatine because I want to remain lean and solid and have already done the pro-hormones and gotten hair loss as I am predisposed. I realize there are a million other things to try out there as well but I just wanted something to give me a little extra pump.. anyways if addy is a vasoconstrictor would that mean that my muscles would not be getting the most use out of my workouts/supplements.. etc?
