Out of that last all I've heard of is Schering, and that's top of the line stuff.. But being top of the line, it's also more prone to counterfeiting.. It's also 1 of the most expensive forms of Test E you'll find, cuz it's human grade and sold by 1cc amps.. I hear it's also more painful than other Test E's.. So if it's the real stuff, you definitely kno exactly what you're getting and exactly how much - but that's not to say you'd get better results than any other brand of Test E that was also legit and accurately dosed.
