I actually have an empty bottle in front of me now, I save all of my old bottles, it's a good way to keep an eye for the fakes. Anyway, it does have rounded out sides white rubber stopper and an exp date stamped on the bottom it says 015AG005. Hope that helps. Alot of people have negative things to say about this, I used 500mg a week on my first cycle along with ttokyo eq and gained over 30pounds. The sides are like the other bros said they suck I got mad back zits too. Good luck
