I recently picked up some Deca 300. It does say Deca300 but also narodeolene decanate(spelling may not b correct) directly below. It has a made date and exp. Date but no LOT #. It came in a clear 10ml bottle with a blue and silver label with a blue plastic top. It has an abbreveation AT but no water mark or hologram. I've used several other deca's but never this. Not sure if its even real. I will try to post a pic.
