Max length time frame from cycling

Postby Valdekio » Mon Dec 08, 2025 10:21 pm

I just have a quick question for the board or at least those who have been cycling or are done cycling. How long after starting cycling was the maximum length achieved. My urologist said to cycle everyday (1 hour) to max for a year but certainly max length results are achieved before then. Appreciate feedback as I am at 11 weeks post surgery and cycling everyday since six weeks. I did a couple of cycles on my own prior to the six week appt. but nothing regular.

Has your length maxed out or are you still seeing gains?

I felt “ stretched “ for the first couple years at max pumping. Now at almost 5 years I no longer feel the stretch at fully pumped, my pump goes flat, I believe our penis will grow in minute ways for many years. Even now im an nearly an inch from my youthful- pre Ed size of 7.25” but our bodies try to correct over time.

I am also an inch shorter right now from my youthful size of 6". I am hopeful to gain a little more of that back though as I continue to cycle.

Tracking size gains is very slow. Like some people say watching grass grow or paint dry. Gains kind of quickly slow down to a crawl. As a group, us men aren't very well known for our patience.

I wouldn't post my size here until the 6 month mark. But in all honesty I could tell before then that I would get to 6" girth. It was very close to 6" at 6 weeks. I wasn't surprised because my historical girth was around 6".

Have patience, cycle as much as you can. Gains sometimes take a year or more to be all done.

It seems many people have a different experience on this topic.

I've spoken to one guy that was implanted by the highest volume surgeon in the UK and he got no gains from cycling.

I spoke to one guy that was implanted by the highest volume surgeon in Germany and he got no gains from cycling, but he believes his early cycling from day 3 onwards prevented further size loss. He said he lost a total of 1cm length and 1cm girth from the implant.

I've also spoken to someone that says he gained about an inch over a 6 - 12 month period. This took him back to his natural length. He was implanted by the highest volume surgeon in the UK.

I spoke to one guy that says he gained 2.5cm from cycling in the space of about 2 months, but he was undersized and lost a total of 4cm from the surgery. So he's still shorter than his pre-op length. He was implanted by a low volume surgeon in Ireland.

I personally am 4 weeks post-op. I started cycling last week. I was implanted by a high volume surgeon in the UK. I was left mostly deflated for the first 3 weeks. I was bone pressed 5.5 inches immediately after surgery. This went down to just under 5 inches after I was fully deflated on day 22. Since I started inflating last week I'm now stretched out to a bone pressed 5.75 inches without glans engorgement. I'd be surprised if I get much more than this to be honest. My penis narrows at the top. It incurred a bit of fibrosis during the implant surgery. It's not getting thicker at the top, and as for length the cylinders seem to be rather comfortably pulled to the right length at this point. When the penis was below 5 inches it looked and felt bizarre, like everything was compressed and folded up inside it. Almost immediately after inflating on day 1 or day 2 of cycling it stretched out to what it is now and has not good longer since.

However I have seen guys claiming whopping gains from cycling. I can't really get my head around how that can happen though. I'd say if you're going to gain anything you'll see most gains in the first few weeks. Also according to literature the surgical capsule is finished forming around the implant at about 12 weeks.

The “gains from cycling” you are going to get are different for length and girth. There are no scientific studies on how “cycling” affects how much length you get back, though there is at least one study that notes almost all guys eventually get back to or exceed their pre-implant length (but without studying whether “cycling” had anything to do with that). Other than that, there is only anecdotal evidence and some theory. Docs get a lot of anecdotal evidence, and we get a lot here. I am not a doctor, but here is my read for reading a zillion threads on this, and inherited wisdom from brothers that came before.

For length, the relevant inputs are 1) math, and 2) how atrophied your tunica is from ED.

The length math is pretty simple. From what I understand, most guys are going to max out at about 2/3 to 3/4 of the size of their implant plus RTEs.

So, Valdekio… if you have an 18 + 1.5 you stand a very good chance of winding up with a 5 1/8th to 5 3/4 length, depending on how deep your crus is.

If you manage to get over that higher number, it probably has nothing to do with cycling, it’s that you have an extremely shallow crus. Possible, but unlikely.

Why? Because implanted penises simply don’t get longer than the length of the implant. No amount of cycling will make the implant bigger, all the cycling is it is doing is getting the tunica to allow room for it to stretch out to its full size.

BUT, they can be a lot shorter than that, because the cylinder is compressed inside the tunica. The tunica shrinks and compresses from lack of use. If that has happened due to ED, it may be reversed somewhat with VED use prior to implantation, and cycling post implantation.

Here’s the bottom line on length: you can’t grow past the size of your implant (there are claims the LGX can, but that is somewhat minimal/doubtful). So if you are already near the max length of your implant, your gains will be minimal. But if you are way shorter than the max length of your implant, you will likely gain a lot over the NEXT YEAR. Be patient.

One brother put it like this: if your immediately pre-implant size was an amount that fit into that 2/3 to 3/4 of your implant range, you will likely wind up with about your pre-implant size, give or take a little bit. If it does not, you were either undersized (and your implant doesn’t extend into your glans), or your assessment of what your pre-implant size was is off.

As for girth, that is a much different story, because the implants are designed to expand in girth as much as the tunica allows (though there is a limit there, too). There the relevant question is simply the elasticity of your tunica. You are likely to gain back whatever girth you had pre-implantation, and possibly a bit more if you can stretch your tunica somewhat through cycling.

As a result of all this, it is very difficult to determine a “one size fits all” gains from cycling. Some guys come off implantation with relatively healthy túnicas, and as a result have very little length gains from cycling, because they are already close to their potential. Other guys like me gained 1.25 inches over the course of a year until our penis was capable of expanding to the full size of the implant that was put in us.

You can’t really know how deep your crus is, so it makes sense to simply cycle for a year and see where you wind up. Studies have shown almost all guys eventually wind up at their PRE IMPLANT SIZE (but note, that size is not the same as the size you were when young or pre-ED, as your tunica may have atrophied).

There isn’t some magic to cycling. It’s just completely inflating (to the point you feel full and the pump stops compressing, don’t over do it) and completely deflating on most days. Many guys do that for masturbation/sex. Early on you may need to be a bit more dedicated, but it is not some crazy dedicated activity. Just do it, and be patient. Perito exercises can’t hurt, either, but again, there is no evidence - or theoretical path - to that expanding your implant length beyond its limit. I think Perito is mostly for girth, and may not actually do anything or at most accelerate it a bit. But it certainly can’t hurt (unless you do it til it hurts).

You can say that, but you’d be wrong, lol. It’s mindboggling how many guys have told you most gains aren’t seen until six months to a year later, or have tried to explain how gains happen, yet you don’t seem to bother to read it.

I am starting to theorize that it takes 6 months for the implant material itself to relax and these later gains are really just because the implant is able to continue the slow march towards bursting (provided your surgeon gave you enough extra fluid).

I was insane about my pre-op pumping (reaching +1” in the VED the night prior) and was at my full natural length right after surgery. I hope this means I stand to gain but even if not, it is clear that good vacuum training and a good surgeon can keep you from taking a loss.
