I wonder about the true prevalence of fake gear in Thailand. We have all heard anecdotally that it happens, and I do not dispute that it happens. I simply wonder if we're not imposing our own perspective and suspicion, based on our experience with the frequency of counterfeiting we find here in the west (I've gotten burned, too, so I will probably always have that in the back of my mind.) It just seems odd to me that someone would bother counterfeiting legal, cheap substances. Particularly when there is very little local demand for them. You know what I mean?
Would you worry about buying fake aspirin? Extrapolating from the prices they command here, which I assume to be wildly inflated due to black market economics, I assume they are pretty cheap there; maybe cheap enough that it would not be a significant savings to make convincing counterfeits, vs. making or distributing the real thing--which also avoids the risk of being exposed as a fraud and losing repeat business.
Now, with something exotic and expensive like GH, I would definitely be wary. But for Test or DBol or whatnot, the margins just aren't there to make it really worthwhile. Why counterfeit 1 dollar bills when you can print 100's? I would be a lot more confident buying stuff directly from a pharmacy, than mail-ordering it through intermediates. Just my 2 cents. No real data, I know. But I doubt that exists anyway.
