I've traveled all over the world and the easiest pick for your needs is Thailand (been there for the same reasons). Cheap and good gear (just make sure to use Hg). Women and food are also cheap in Thailand and they will treat a white man like a king, so you don't even have to pay for the pussy. Only problem over there is finding a good quality gym. Most gyms are all about "fitness/wellness."
Greece is an awesome country, but gear isn't that easy to get anymore and the country is much more expensive in every way compared to Thailand. I'd stay away from Turkey, that country has so many scammers and thieves it's not even funny, they will try EVERYTHING to get you to part from your cash... (Of course there are good people) and all, but it's not nearly as "bodybuilder friendly" as Thailand...
