Bunk Qv

I think I may have used a bottle of bunk QV..My source is very reputable so im not worried about him. Now im worried about those rumors saying QV was being faked right at the source. I have used QV for years and always loved it. Never a problem. But im using prop right now and prop is one steroid that if its fake u can prety much tell by the effects it has. I have gone thru 3 bottles so far in 3 weeks.The first bottle was good, made me horny as all hell, which I love when im on the shit...Feels good..Well i went onto the 2nd vial and for some reason my sex drive diminished. Like I wasnt on Prop at all. Im now on the 3rd bottle and holy shit my sex drive is back thorugh the roof again...So im very skeptical right now..Has anyone else had any problems or issues with QV or has anyone tested a bunch of batches...Im into my 4th week coming up and debating on switching over to Animal Power..I would hate to waste a 16 week cycle using some real shit/some bunk shit and get no results...
