It's been a long long time since I posted on this thread. So I'll report my own experience with the JP90 since 17 years later it still gets attention from newcomers. I hope this will be helpful to those who need it. "Take what you need and leave the rest." I think that was a slogan in some human potential movement. It seems like good advice.
Not to rain on anybody's parade, but the JP90 didn't work for me. I'm by far "not alone" which is kind of an understatement in my humble opinion. I was one of the first to try it way back in 2008 and even got some personal advice from JonPop. I've watched most guys who try it report zero gains after 90 days, and then defenders of the plan switch it up with the sudden pronouncement that it's only a "conditioning program"!
Ah, but the JP90 is basically how JonPop himself says he gained up to 2 inches within just about 7 months back in 2003! You can find his old posts on the Betterman Forums on the WayBackMachine (Internet Archive) to confirm what I'm saying. He also started on testosterone replacement therapy (TRT) for a serious deficiency which he had lived with for years, maybe decades. He was 60 years old when he started all of this. The TRT significantly improved his erectile health and was surely a major factor in his reported gains. He talked about this in private messages with me too. Somewhere in these forums you will probably find him talking on this subject too, but I find his 2003 posts on Betterman illuminating.
So keep these things in mind as you evaluate information here. There are many variables in play, including placebo effect. We are all susceptible to it.
If the JP90 or any other routine doesn't work, there are other things that might. Maybe. I found my own way with focused traction and there are several ways to do that. Jelqing/milking techniques and the like produced nothing and I now understand why.
All PE is experimental. Nothing is guaranteed. I admit that I take a much more conservative and cautious view of the PE scene than members of these communities typically do, but that's for good reason. I've learned from hard life experience that if it's bandwagon, it's probably not nearly everything it's cracked up to be.
My personal "broken record" advice (which nobody ever follows) is always to focus on ONE TECHNIQUE ONLY. Master it as a skill. Eliminate variables so if you gain, or DON'T gain, you know what produced the result. Avoid routines that shotgun a variety of techniques and devices hoping to hit it from all angles. Gains are typically going to come from one applied force and you'll never know what the winning technique is if you're doing 2 or 4 or 6 different things at the same time and mixing all those variables.
I understand that guys want the magic. They want to go through the motions and get what they want. PE just isn't so simple. I learned that the hard way. I mostly failed. Until I succeeded. And you'll be surprised by how big a small success in PE can be! Go for any gain at all and learn from the real gains. Trust in your results only. It's the only empirical data you will ever have to work from, so make sure you can trust it by being methodical and thinking critically about your own subjectivity.
I succeeded when I took a more minimal and focused experimental approach which demanded strict empirical observation of results and unforgiving measurement protocols. I didn't know if it would work. I tested it for its merits. I studied what I was doing very closely and tried to find ways to focus the forces into the deeper target tissues. It required careful thought and development of technique. It required problem solving, and yes there were superficial skin injuries which healed with short periods of rest.
There was no "going through the motions" about it. It was work. Usually tedious, but always an education.
I also wasn't pursuing a fantasy or an improvement in my self-image. All I really wanted to gain was knowledge one way or the other. I wanted to know if this stuff was actually working or if it was all just some sort of collective delusion. I committed myself to an empirical trial using my own body as a test subject. I did this fully aware that it might not be a good idea. I took 100% responsibility for the risk. I can't in good conscience recommend that anyone else do the same. It's totally up to you if you come down this path. If you do, you do so without my encouragement. We all have higher and better things to do.
My results were mixed, but I did gain. There is no delusion about that much. I can't speak for everybody else, but I can confirm that my results mean that at least some other guys are gaining too. I can't be the first.
Whatever you do: Respect yourself first and foremost. Do not compromise your self-image or self-esteem over of any mean spirited slights or cultural tropes. Stay safer, have fun, and good luck.
