CYJ, I have really enjoyed your posts since you've signed up, but this one here is just not correct. I have been ordering from foreign markets for years, and (if you go to the right places) they very much are the real deal.
Dex and azium are essentially the same thing, but azuim has a salt added to it to (as you said) make it faster-acting.
For anti-inflammation, dex is 30x as potent as cortisone ...
I agree, I know a lot of people use these drugs to dry out a dog and help them to make weight, but IMO this is a misuse of dex/azium.
