I've been reading lleywellyn's book on anabolics and he did various tests on products from major underground labs. many compounds failed on things like cheap oil, severe over/underdose, heavy metals, even wrong compounds. this book was written in 2007 so things may have changed, but what are you guy's experience on quality of ugl products? what are the chances you get screwed? iirc there was one sample that was dosed at over %1000...
