I used the 30mg pill. Although for my purposes that was a bit too much, delayed me much longer than I liked so I dropped down to 15mg and that was more than enough since I don’t suffer from pe (so you may need more or less depending on your personal predicament). Also I noticed timing is crucial, I waited an hour after taking the pill and had no effect. Next time I waited an hour and 30 minutes and it was a night and day difference.What dose do you use?
