Thanks everyone for the posts and to GotEmAll for the short cycle info. I like the massage parlors/cardio suggestion but unfortunately will be with the woman (like taking a sandwich to a restaurant!)
Strangostrone, I'm going December/January. You should check out the open air gym in Lumpini Park, Bangkok when you go. It's got a great atmosphere and from memory it's about $1 a session.
I've just found in Japan (where I live) it is legal to have a small amount of A.S. for personal use (however I have to check whether it's Ok to bring back through customs) so if all goes well I'll start a cycle in Thailand and finish at home.
I still have a question though: is a once only (or once a year) short cycle going to be effective? Is such a cycle going to help me jump off the plateau I'm on and fast-track to a higher level (and stay there without using)? Cheers
