Others don't know, but it really works after conditioning, because I have some problems in this respect and my wife is not very satisfied. After seeing Yibang's health advertisement, I consulted, and their consultant gave me two plans, normal and enhanced. I chose the enhanced version with a certain economic ability, and the price is more expensive than the ordinary version. Then about 30 to 40 days, it really improved a lot. I hope I can help you.
