Broke into chalk

Posted by Reviewer1745811 on May 28, 2016

I had to throw these away since impossible to use since they crumbled into a chalky dust within a couple of weeks of opening. Sad, but returning to capsules which don't disintegrate immediately.

Great product! Works as intended

Posted by 5359042171288643262 on Feb 11, 2016

When I say "works as intended", that means that this had a huge effect on my erection strength. I have no issues with bloodflow to that specific part of my body, but holy cow this was insane, it really does boost bloodflow to the little man! If I ever do end up having ED I now definitely know what to use to help with it.
