I know alot of bros on the board keep some on hand for after cycles. Ive actually tried it myself, and needless to say, was happy with the results. I also tried the generic version of it (sidenafil citrate) and it worked basically the same. However, the two side effects I noticed the most were facial flushing and nasal congestion. Do these same side effects occur with Cialis and Levitra, or even the liquid form of Viagra, or is the same for all of them? And for those that have tried generic viagra, did you notice any difference?
