Hi frankeij,
Sorry but none among the suppliers listed at SaleHoo offers Meizitang Botanical Slimming Pills.  I planned to refer you to their company's official website but I am not satisfied with it's look.  I am not confident to recommend any, especially if its a pill to be taken with extreme caution.  There are a lot of scam suppliers out there and if it something that may affect our health and safety, we need to be very careful.  I hope you understand.
Thanks!
