Andro instructions start to get very intense, to be honest I don’t see how the people in the trails were following them in the later stages.
I started getting cut once I was stretching at 9.2”, I spent ages just stopping and starting because I wanted to try my hardest to follow the instructions, I was stretching 1.6” over erect length at one stage, lol I’m surprised I didn’t rip my glans off.
Have you got a link to your modified extender?
I have my fingers crossed for you ;) .
