There is a german guy who i know, who confirmed this for me. I was taking 400mgs a week primo and like you said it was doing good, but to my dismay it was not primo but this nan phenyl. so it roughly works to 200mgs a week of it and with anavar and tren I was cut in a good amount of time and hard.

Now thats going to up to you bro, if you really know thats what you got then do it if not at least use it on the bi's and areas where they are slacking, like synthenol..that might work too..lol
Its your call but they are not all the same..the blue dot is not uniform and small either the real ones i have had are smaller blue dots and the labels are a peel off but stays in layers..the fakes pretty much come off in one piece.. i will post pics if the fakes and real soon. its on disk somewhere.
