9cyclops9: Well, in my experience, it depends upon what you do in addition to the pills. They don't, as the companies claim, work by themselves. I've been taking VP-RX for almost three months. The first two months, I did nothing else. I gained nothing. This past month I've been jelqing 500 reps 5 days per week and doing some extensive PC excercise, and I've added half an inch in length and a little over a quarter inch in girth. Which, by the way, is quicker than I ever gained doing the excercises by themselves. So a combination of the two seems to work quite well. Needless to say, I'm buying more pills soon and will keep doing the excercises until I reach my goal of 8.5 inches long. Or maybe 9 if I get that far. Anyway, I hope this helped and good luck!
