It depends, in Brazil it's extremely easy to obtain, I have 12(360p) of Diazepam, 23(690p) of Clonazepam, 11(330p) of Alprazolam.
The easy but not cheap way is to make an appointment with a private psychiatrist, which is the easiest way to get prescriptions for anything in Brazil.
Forgive me for reading your question too quickly, I've already had success buying benzos through telegram (I don't have the group contact), sometimes on shopping sites with different items(names), for example>bb gun pellets= Ritalin, it's very easy to be tricked into buying on the internet, it's better to get it from a psychiatrist
