I have been prescribed Viagra by my doctor to treat ED. I take pre-workout supplements (Muscle Pharm Assault) which contain L-Arginine and Beta Alinine (nitric oxide), which I read doesnt go well when taken at the same time as Viagra. In addition, I take Creatine and Whey Protein as well.
I am not planning on taking them at the same time though. Could you advise if it is safe to take these on the days when I am not having Viagra. Also, how long do I need to wait before I can take them.
