I assume Russia Dog is living in Thailand and knows what he's talking about with what's available. Too bad you can't get any test prop, since that's really what would be best for a short 8 week cycle. Don't even dream of trying to take any into Thailand - very strict drug laws as far as taking in, going out, etc.
Here's what I would personally do....
I would get the "sustanol", which I assume is sustanon 250. That's got some test prop in it along with some medium chain test esters and one long chain ester. I'd go with 250 mg EOD and I'd start with a 500 mg front load as soon as I got there and keep shooting until you go to the airport.
I'd also get some BD d-bol (god I love this stuff) and run at least 50 mg/day. Run the Nolvadex 10 to 20 mg/day to keep the bloat down, maybe the proviron too.
Workout hard, maybe twice a day and eat good and healthy. You'd make some gains. Going back to home you'd still have some AAS in your system and should keep hitting it for two more weeks, then start PCT. A wise man would order his PCT from ARR ahead of time and have it waiting at home. DON'T try to bring anything back with you, even PCT meds.
As for sources - well I've heard there are good and bad pharmacies in Thailand. Go read the article on it at
www.t-nation.com. They did a Thailand trip and did a write-up about it. If it were me, I'd just go to one of the local gyms, make acquaintances with the biggest dude I could find, and tell him what I'm doing and ask for his help. Chances are the guys at the local gym will know what places are good and which are bad.
