Im on it now I dont think it is underdosed and mine is definately not faked I trust my source but there may be some floating around not heard any info on this. Im seeing pretty good results and im taking it with some of that "bunk" RSOC primo.
Some things Ive seen different with QV fakes are squared not rounded corners, the newer batches all have the QV letters on the flip off lid and the fakes with the most recent lot number do not have this, and look at the holagram the fakes will not have color in them when viewed at an angle the real ones have a rainbow of colors u can see.
Hope this helps
