Actually there is a article about UGs in the new MD Mag, and it will open your eyes. I have to admit I have injected GALLONS of gear Ive made myself, but no matter how clean you are, how good of a filtering system you have you just can NOT make it nearly as sterile as a multi million dollar pharmacy with equipment that we couldnt even obtain without a liscense. I must say there are some good UGs out there, but it just bothers me not knowing who is making it, just like the recent bust (forgot the lab name) but the dude was arrested for child molestation and they found his lab, im NOT saying that all of them are sickos I would just rather know my gear is being made by factorys and machines....Just my .02.
