Guys, to make a long story short, if you are messing around with ED/Penis Enlargement drugs like Viagra and the injection stuff i use, you need to be aware that a prolonged erection for over 4 hours MUST be medically treated. Going untreated, you will run the risk of never being able to get hard again. Please use these drugs carefully. FYI, the first step for treating a prolonged erection is 120MG of Sutafed(spelling?)
