I have not tried either but it seems wonderup is mentioned most on here to be successful but every one is differant....i'll be interested to see what the others say......laisegirl
I would chose WU..
If you visit the BO section you'll notice that few people had luck with BB plus it is very pricy!
Some have lost their gain after they stopped.I only know Michelle Choi who kept her growth from BB..
If you are into BO you can simply buy it seperatly..After all BB is only BO +pituitay gland + something else i think but can't remember what it is.
So you can get the same ingredients and save a lot of money..Just my thought.Good luck!
