big pharmaceutical companies can have bad batches of product too...two years before i was born my brother got a measles's vaccination that caused his brain to swell and it killed him. Yes we would think there's better quality and sterility with pharm gear they can fuck up too though and some ug's are very good but you need to do your homework... I've seen a lab test on some UG enanthate labeled at 250mg/ml come back from the lab at 289mg/ml! and then again some guy's get some bad UG gear and really pay the price for it. so it just depends on your own preference's and what kind of UG gear we're talking about because some are top notch and at the price are a no brainer. my two cents.
