Hang in there quick4life!!
I am basically in the same boat. I have been here since 2004 and basically haven’t gained anything. However, I have had to take a few breaks for injuries and such. When I did get injured I felt like I was getting close to some real progress each time and I would be kind of bummed out about losing the time and temp gains by the time I healed up. Hopefully I will not get injured again since the last time was the worst so far and I haven’t even gotten close to going too close to the edge since the last injury. I also have not been as consistent as I have needed to be in the past.
So like you, I do believe it works, but the cards have just not fallen right for me yet.
The one area I have definitely gained in is the flaccid area. I hang 10x better than I used to. I am pretty sure that is from pumping.
