It depends on the tension of the band. If you are using a tight Osbon tension band, the 20 minute rule should apply. However, if you are using a “stretchy” type band, the time under tension can be increased significantly.

After four years of a family aggressive pumping regimen, I gained about 1” in permanent girth. Five years later, with occasional maintenance pumping, I have still not lost any of my gains. Last March, I took a three month break from pumping without loosing any of my gains.

510 is well within the normal range for 62. When I was in my early 70s my T level was 290 - 319 and my endo said it was normal low for my age.

You don’t need a vacuum gauge with a medical grade VED. You should get optimal expansion within five minutes which shouldn’t cause any issues. I have had great success with Osbon tension bands.

I saw it and my impression was he had a single episode of psychological ED and it was over played and not properly explained.

Before my ED became severe, I found that tongkat ali and l-arginine taken several hours in advance of intercourse helped, but I still needed PDE5.

I also think the same.

A normal erection is one that is rigid enough to achieve penetration. Scientists have a more precise answer: in most men, the pressure in the penis during an erection reaches 100 mmHg, a measurement of pressure.

What type of pump/constriction bands were you using?
Once PDE5s and injections stopped working for me, a medical grade VED and Osbon tension bands became the only way for me to generate and maintain an erection.
