Genesis do not exist. They shut down after the big bust in 2009. They relaunched as Unigen in late 2010. If your manufacturer date is post 2010, it's likely fake. Still a great deal of fakes out there. My experience was extremely underdosed gear in 2010, even with a pre-2010 date...
FYI - this is not pharmaceutical gear. Even though it's often touted as such.
