Or some call it inverted Ugrip, I used it in 8 weeks and didn’t get any results on girth (I did increase on length but it’s more due to manual stretching), so I started from January 2008 to jelq with a tight ok-grip, and it gave me results before, and will do again.
PS: on the contrary of ok-grip inverted Ugrip gave me immediate visual results but it didn’t last so basically it’s not effected, at least for me.
