peel the hologram off and see if it has uso vetenario (not sure on the spelling) typed behind the sticker. also, it might not have brovel labratorios ( spelling) on the metal rim around the stoper. the new bottle dont.
I got some test 200 too with the blue flip off top. No hologram. not sure if its fake or not. I've heard that test 200 is hardly faked but I could be wrong. I'm stacking mine with some maxigan which I know is real so I'll be making some gains.
