I personally enjoyed taking BO, I didn't see crazy big breast growth from it, but its more of a longer journey than PM which gives you more quicker but also goes away quicker. The biggest changes I saw from BO were weight gain in my hips and butt and feel like my breasts protruded out more more underboob and the front comes to more of a point now.
I've been off everything since January and I still feel aches at times and haven't lost anything I gained during my time which I attribute to BO having more stay power.
