From the pics, I would say it looks genuine. The arabic writing is not something to worry about, especially since most bottles sourced from the grey market (fragrancenet) have that sort of text. It just means that the stock was obtained from one of those arabic speaking areas/countries. If you are not satisfied with the smell, return it back to fragrancenet and get it replaced.
Hedonist, I have a question for you: A lot of the creed bottles I have come across from fragrancenet have arabic writing. Now that is fine and dandy, but they also have something like "PGS TOILET WATER" followed by the batch code on the back of the bottles. Given your current location, I was wondering if you have come across CREEDS purchased from retailers in Abu Dhabi that also have such writing on the bottles. This would really explain why Creeds obtained form authorized sources (in north america) never have this kind of writing and why grey market creeds ( potentially obtained from arabic speaking palces) always have it.
Any input would be greatly appreciated.
