Is it actually legal to buy anabolics in Thailand or do they just not care?
You aren't supposed to buy drugs without a prescription here
BUT
It's a poor country, a lot of people can't afford doctors, the pharmacist therefore ends up being a bit of an 'on the spot doctor'. It's pretty normal to go in, describe your symptoms & get prescription drugs right of the pharmacist. I do it myself if it's a fever/mild infection.
Where the line is drawn is on the 'get high' drugs. Codeine, benzos stuff like that are more strictly controlled. Exact same laws but it's just they are enforced when it comes to opiates & benzo's.
So yes, strictly speaking it is illegal but no, you won't get busted for it.
