its actually not a joke
the viagara + arginine method is commonplace in competitive bodybuilding. Ti leads to an increase in overall body NO2 production resulting in a fuller, more vascular appearance in the musculature.
Viagara only works to get you hard if you are being manually stimulated while on it, in the unlikely event you have someone jerking you off before you go onstage or the head judge calls for the "masturbation pose" you will be fine
