From roughly 9 inches to almost 10 and a half inches!!
I was pleased to see that they had released the Hydromax X50 as the X40 was too small for me. This pump is just incredible. I combined it with jelqing like most guys are doing and in the 24 weeks I’ve been using it I’ve gone from roughly 9 inches to almost 10 and a half inches. I was skeptical that a pump like this could actually add any real size long term but I’m a believer now.
