Myostat. . . 1 year later

It has been around 1 year since Myostat has come out. I was wondering what everyone’s experience and results have been thus far. My year of training has been inconsistent at the best. But I stuck with taking Myostat, just in case consistency struck. My lean mass seems to be up around 15 lbs, when it should have dropped considerably. Im not sure what I should attribute that to. Was wondering what other people have experienced since then.
