I couldnt tell you the weight, but MG refers to the amount of ACTIVE ingredient. So 5mg of dbol is 5mg of only the active dbol, there are also other things in the pill to bind the active chemical with the filler to create the tab. So it will be a little heavier than 5mg I'd assume, how much I can only guess. This is just from my reason so its my .02.
