Optimal Pumping Profile for Length

Optimal Pumping Profile for Length

Hi,

I own a CTC Digipump and a Velseal cylinder that I nearly pack girth wise before pumping and I was wondering what type of profile would be better for length gains, one that alternates pressures quickly (say every ten to twenty seconds) or, one that alternates pressures relatively slowly (say once every couple of minutes)? Any response would be appreciated. Additionally, could a mod please re-post this in the Pumper’s Forum the website wouldn’t let me post it there myself.

Probably the best thing to do is try both ways. You can do one week with short cycles and one week with longer cycles and evaluate the result. In the long run, it is probably a good idea to keep mixing the routine up anyway as growth often occurs when different stimuli are presented. So don’t get struck in a rut just doing the same thing over and over.

Someone finally popped their posting cherry- congratulations!

Not many guys that I know of here have the top shelf CTC pump- so you will likely get answers like mine that are inconclusive.

Having used both a handpump and a kaplan electric pump [adjustable for pressure only, not cyclic rate] I get a sense that once the tube is packed the cyclic pumping may have more impact for growth.

I still disconnect the pump for static pressure, but only because I got shit to do and need to move around a bit.

Not directly responsive, but I hope helpful.

My Plan

Thank you for your quick replies gprent and androNYC. I plan on “warming up” by pumping up manually between 2” and 5” pressure for about 5 minutes and then I plan on switching to the Digipump and doing 20 second cycles in 1” increments up to 10” of pressure with a 30 second break at 0” pressure every couple of minutes. I’ll keep you updated on my progress.

Think about this way.

Any portion of the cock that is “packed” against the cyllinder - is getting no work or any growth.

I personally think, and many experienced will disagree - that pumping will work best if no portions of the
unit are “packed”.

Ben123, your strategy sounds good. Work it in with heat as well, so that the chambers can stretch more than normal.

Thats what this is all about.

10 inches of vacuum is a lot. Please be careful, and watch your PIs.

I disagree- packing only means that the girth is maxxed out- which would lead me to conclude that the stress is now being directed to length only

No doubt.

Depends on your goals.

What we really need is someone who is satisfied with his girth and who is packing the tube at his current girth to see if length growth results from additional pumping in that cylinder at that point. The warning, of course, is that the conventional wisdom is that too much force at that point will result in water blisters on the glans; not a desirable outcome. The question is, short of that damaging force level, are length gains to be had? My guess is yes, but very good lubrication would be necessary to allow the shaft to slide within the tube accommodate longitudinal expansion.

Lampwick, I’m in that situation now. I have 6” girth which I am very happy with, and I am using a 2” cylinder in an attempt to gain some length. Because of the tight packing involved, I need a full erection and lots of lube in order to get fully inserted at the start of a session. I pump according to ‘feel’ and not to set HG levels, so when using a 2.25” cylinder, typically I was comfortable at 2 - 4 HG. Now when I’m packed into the 2” cylinder I find that 7 HG is required to give similar expansion. It still feels pretty comfortable, and I suffer no blisters or red spots. And the good news is that I have achieved a length increase of 1/8” in two months.

Perfect! Do keep us updated on your progress. 1/8” length gain in two months is terrific.

Have you ever tried going into the cylinder well lubed but less than 100% erect, and increasing the vacuum level gradually in the course of the session? I’m wondering if you would get expansion further down the tube to help your length gains before you’re fully expanded in the tube for girth?

To save everybody else the math, remember that circumference equals pi times the diameter. IrishJim is right there in terms of ‘packing the tube’ with his six inch girth and a two inch diameter tube, which has a circumference of 6.26 inches and a cross section (pi times the radius, squared) of 3.14 inches. Not much room for girth expansion there.

IrishJim’s 2.25 inch diameter tube, by contrast, has a circumference of 7.07 inches and a cross section of 3.98 inches. That quarter inch in girth makes a considerable difference in diameter and cross section.

If your unit is packed against the wall, and friction against the wall prevents longitudinal stretch - and any further expansion of the cyllinder to this point, I do not see how the packed portions recieve any work…

Lampwick; I haven’t deliberately tried entering the tube less than 100% erect, but on occasion it has happened that way due to me struggling to get get quality wood (such as now when I’m recovering from flu). I’m so pleased to be gaining at the moment that I have no plans to change anything. If I fail to get any further gains over the next few months I will definitely try a planned program of entering low and pumping up. The biggest problem I have is a lack of time, as I would love to be able to work to a definite schedule in order to truly max out any benefits from a single routine. As it is, while I’m delighted with the gains, I can’t say for sure what is the best mix of workout days versus rest days for me as it is just so random at the moment.
