QV is a bunch of mexican dirty shit. i may try the propianate to give them another shot but it's human grade from now on after. ide say spend the extra dough. i had to stop my test only cycle short of my 10 weeks cause when i had to stay in on a friday night cause i couldnt walk that was the last straw. my bro quit after 3 weeks. aaaarrrggggghhhhh........i hate that shit. thanks,now u got me all pissed off (lol)
