Avants forum have more threads on this. I never tried it since I'm a little skeptical on how it works. One thing to keep in mind if you were to experiment - there was a study on steroids that showed disproportionate increases in the upper body particularly the arms. And guess which part of the body most people tend to slather sysenhance on??
I'd like to see a bb who is healthy, didn't lose a lot of weight recently by cutting, slap on sysenhance on just one side of the body and document the changes.
