Anyone tried Copax alprazolam?

[Hollywoodjimbo]

Hi all! I think/hope this the correct area for this question. I placed an order with a vendor from the list, my first order. Price was good and I had the same med in the past, Zopax, which works fine for me. After payment they had some week long holiday and finally they said they were preparing to ship. Soon after, I get an email telling me they are sending Copax instead of Zopax. No biggy, I'm open to a new brand, I might even like it more! It was trackable which was cool, but decided to do a quick google on Copax and all I could find is that it's an SR (slow release) or ER (extended release). I do not want an SR or ER, and there was no mention of that In his email otherwise I would have cancelled. So my Q here, anyone have this COPAX? It should be here any day now and if it's SR or ER, any suggestions?
Thanks in advance!
Peace!
