Eh bro... where/when are you going?
I am going down as well. Nor for 3 weeks though. I have been looking into this as well.
From what I have heard. Most gear is NOT OTC in Bazil. But ... there are still a lot of pharms that will sell it to you. Just have to find the right places. All ancillaries are OTC.
There is lots more juice in Argentina aparently. And a lot of vet gear, that is supposedly awesome. Many Brazilians, use gear from Argentina.
There are lots of good bros on this site from Brazil and Argentina that can help you out. Here is some info from a good bro of mine.
To start with, here is a list what Brazilian pharmacies carry (human grade):
Deposteron (test cyp)
Durateston (aka sust)
Deca Durabolin (nandrolone decaonate)
Hemogenin (a-bombs)
Nolva *
Proviron
Clomid (a few brands!) *
Gh
Aromasin *
Dostinex *
Femara*
Arimidex*
The ones marked with * you can walk in anywhere anytime and get it. The others you WILL need a script, but it varies a lot from big cities to smaller ones. But anyways, pharmacies don't LOAD on these substances so it won't always be easy.
Some labs from Argentina to look for are
Dispert
Chinfield
Burnett
Landerdland
vet gear is very popular there.
Take Care bro,
Mavy
