Interesting question. If you use a stretching device for 5 hours a day, 5 days a week, IMO, your penis needs to rest &
Repair itself & grow when not stretching on days off.
I think if your starting number is 5 inches, you can reach 7 inches but it may take 5 years or more, & possibly 10 years.
I don\'t think the ligament cut overall helps much. Some guys it does, but IMO, its minimal.
Yeah the pumping also had my gaining an easy 2 inches in
Erect state, but that the blood being gorged into your penis.
I personally never liked using a pump, because it really doesn\'t help much like a stretcher will.
