I don't understand why people keep saying this drug has no side effects. You don't know that much about it, as this drug really hasn't been tested (thus why it does not have FDA approval). Here's a news flash, pretty much every drug has side effects, which is why you don't take drugs unless you need to. The dopers try to stay ahead of the test, and the reason there are so many positives popping up, is the test is finally starting to catch up (albeit too late for some athletes, who were beaten by these cheaters). The true side effects of this drug won't be plainly visible until the athletes stop using it. I think there are going to be a lot of big names (mostly from Eastern Block countries and Ethiopia) that have a significant drop off in performance this year.
