Just for those who are a bit anxious, I got sides within the first week. I didn't get brain fog, but erections were weak and kind of numb. It took about 3 weeks in total to recover completely but some people take 45 or so days. If it persists longer than that, it seems you're in that group of guys who now want to start a class-action lawsuit.

No one really understands the effects fully, but I'm sure in SOME of those permanent side-effect cases, it's just the psychological shock of your junk not working that causes the problem.
