This little green box is a prescription medication and cannot be taken without a doctor's prescription! Its main ingredient is sanorex, as you can see from the picture. The very famous K Da on Twitter has reviewed this drug.

"Finally someone asked about this Sanorex, Novartis' appetite suppressant, the ingredient is mazindol, which is advertised on Taobao as the only one recognized by the Ministry of Health and Welfare, of course it has to be recognized, but it's a professional! The company is a professional! The drug! The actual fact is that the actual drug is actually a good deal more than the actual drug! Just because it is a drug, so they do not know how to buy and eat and find death is no difference. Just two tips, one, its predecessor sibutramine, we all saw what happened, and two, addiction, reduced efficacy." --Reposted from kenjijoel twitter

I hope people really don't buy prescription drugs to take! While Japanese drugs are safe, that's for sick people! People who aren't sick take prescription drugs indiscriminately, and even if the drugs are safe, something will go wrong!
