I read this on an aneros progasm review on amazon from a confirmed buyer.
"It seems a few aneros users have suffered problems with over-active adrenal
glands and dopamine after having Super-o's, use with caution!! "
Questionable how massaging your prostate could stimulate your adrenal glad.
You can write your own review setting the record straight about aneros. I've noticed a lot of people respond to other people's reviews when they disagree. And Amazon doesn't fact-check.
