Outside of a lab test there is no way anyone can possibley know whether your tabs are legit. There are so many different labs stamping out d-bol with no distinguishing markings there is simply is no way to tell.
"Russian" - BTW there is more then one brand of Dianabol coming from there are unidentifyable once removed form the strips.
"White tabs no line down the middle" - Stop by GNC or your local drug store sometime. See how many tabs fit that description.
