Interesting. I have been on Swansons BO for only a week and half but have experienced no changes at all - not even the soreness or sensitivity others have mentioned. At least I've had no trouble with erections (which being married is important for me not to llose). Started out on 4 in the morning and 4 at night, though after a week I upped to 5 in the morning and 5 at night.

I've heard others say it will take several months before any noticeable changes, but how quickly should you at least feel something going on?
