Vacuum Pumping 101

Have you every done ULIs or (manual) clamps and measured at the same time? Others apparently get an instant expansion in girth. I do not — only under pressure in the tube. (Can you tell that I’m looking for more similarities between us so that I can get even more inspired by your progress :-?)

No, I take time and heat. Sounds like you and I have a similar tissue response.

I think the heat will do good for you.

Also I find if I use the thera-p all day, my girth is under slight expansion all day…so when I pump that nite, I get bigger faster.

Otherwise, its like starting from scratch each nite.

The biggest factor for me though is heat and mild to moderate vacuum, done very conservatively.

I’m telling you, my biggest enemy to growth has been enthusiasm! I see growth and I start to double my time and forces….and it immediately stops!

I think this is common to PE’ers. We see gains and then start to really go for it.

How many times do you hear that “I made great gains at first, then I added this and that and soon gains stopped.”

Thats why I and lots of vets say” if it ain’t broke, don’t fix it.”

Even Avocets beginner recommendation…very conservative…right?

Too much for me! It’s taken over a year for me to get this though my thick head.

If you learn to measure daily, accurately, you can get the feedback needed to begin to taylor your routine to your ability to recover and grow.

I would recommend beginners to avoid the real intense stuff, like clamping and ulis. Not just to avoid injury, but those exercises generate such forces that I think that most guys will slide immediately into overtraining.

I think I had a thread on when I pumped while clamped. Awsome expansion!!!

Followed by a half inch loss in length (and who knows on girth!) that took about 3 weeks to recover from!

Imagine if you aren’t paying attention and do a routine like that for weeks…months…and in your frustration of shrinking…you crank up the PE even more!

I think we read this all the time with guys that say they started (fill in the blank) and soon were up to ( fill in the blank) and made great gains at first, but now have hit a brick wall.

Vacuums of 10 in hg, wts of 20-30 lbs…insanity for most of us! I guess some can gain from that, but I’d say damn few.

Pe routines taking up 4-6 hrs a day…I can’t even imagine. My dick would fall off!

Got my new Kaplan tube yesterday…naturally I had to take it for a test run.

And also naturally, I overdid it. Today measured 1/16” shorter today, so I took the day of ( just one ADS of Montys pe wts).

I will probably take tomorrow off also, but I will measure to back up that decision.

I was waiting for the tube decal that was coming with the tube, a ruler marked on a clear decal, to apply to the outside of the tube.

I thought it would be great, so I could be accurate to the 1/16”. Well, when it came, it was cheesy. The markings rub off with finger pressure.

So, I went to the hobby store, got a fine paint brush and some black model paint (Testors).

I put the cheesy decal on and used it as a guide to apply the paint to try and reproduce the markings…it came out fair (not great).

After I was done, I peeled off the decal. It will be a great addition in my quest to do daily accurate measurements.

Kaplan recommends the penis tube mon-wed-fri and the larger tube for tues-thur.

He feels that the larger tube stretches the suspensory lig.

If that is the case, hanging would probably do it better.

That actually might be a good routine, pump m-w-fri and hang tue-thur…with the weekend off.

That’s why I like the daily accurate measuring, I can try any approach and get fast feedback as to whether I am on track or note.

Because the large tube includes the testicles, I wonder if it increases blood flow to them also…and if that has any effect on testosterone levels?

For those of you who have used the large tube…did you notice any effect on the testicles and/or sex drive?

Low-pressure pumping like clamping?

Inspired by sparkyx, I’ve been experimenting with low-pressure pumping. Every few days, I do 2-3 sets (5 min with heat), followed by 5min cool-down.

Then for the first time, I tried clamping. I’m using the 1/2” leather strap that came with the Kaplan pump. For the first time, I measured more than 5.4” out of the pump, namely 5.5”. I know, not too impressive to most people, but with my hard tunica, it’s damn good.

So, the last two times, I’ve mixed pumping and clamping:

* Warmup (dunk in warm water)
* 5 min pump with heat lamp, 2 min jelq
* 8 min clamp with heat lamp, 2 min jelq
* 5 min pump with heat lamp
* 5 min pump without heat lamp (cool-down).

Then a thought struck: isn’t clamping very similar to pumping at low pressure after all? Clamping does provide a low pressure. Pumping seems a little nicer: no pinching skin, even pressure from head to toe^H^H^Hbase, easier to maintain full size.

So depending on your privacy, you could do either. At work, you can sometimes clamp, like Big Girtha suggests. The pump is bulky and requires more time to hide if a visitor shows up.

ll (AFK for the next couple of days)

By the way, I’ve started wearing my leather strap as an ADC - all-day clamp. Well almost. I tighten it just a little, so circulation remain good, but it keeps my FG at the high end of my normal range. Nice.

Start: 6.3 x 5.2 (Feb '05)

Now: 7.9 x 5.65 (gain 1.6 x 0.45) - SFL 8.6"

Goal: 8.5 x 6.0 - Currently trying: handclamp squeeze, O-bends. My data - Progress log

I find that some type of moderate all day constriction makes a big difference in my girth gains.

The thera-p band or something similar that increases venous back pressure without decreasing circulation to the point of discoloration.

I find 1-2 pe wts plus the constriction is a neat trick for length and girth!

Lars, keep up the good work and keep reporting back!

I really find the heat during expansion, and cool DURING expansion is one of the keys for me.

I’ve been pupmiping all of 3 days now and everything seems to be going ok except i’ve noticed my flacid hang isn’t as good as it was before starting. While i wasn’t expecting it to hang any longer after such a short period, at the same time i wasn’t expecting it to hang smaller. I’m going to follow pumping 101 religiously so my 3 sessions sofar have been 10 mins at around 4 hg. Has anyone else experienced the same thing? If so how long will it stay like this?

I haven’t seen real gains yet, but in the morning, before reapplying the ADC, I hang a little longer FL. I think this is because I put the strap around my base AND my balls, it tends to push it all out, anti-turtle.

Sparkyx, I know you carefully measure EL. What about EG? Do you have hard data on gains in the last month, after you started low-pressure pumping? I think you said it seems fatter, but I’m unclear on what you have actually measured so far. For me, I only see that extra 0.1” when clamping right after your low-pressure pumping routine.

No, I don’t keep accurate girth measurements because I don’t know how to do it easily.

I keep apx track with my fingers. I make an OK sign with my index and thumb and go by that…hardly precise!

I have been slowly creeping up in length, I’m now at 7 15/16ths at 3 in hg measured cold, and within about 2 minutes.

Girth has been fluctuating…I’ve been studying it and have some theories floating around in my head.

I wrote a thread on PI’s and gains and one of the things that became apparent as I read and questioned others, as well as my own experience…as you gain girth, you have a thicker flaccid during that period.

Duhh you say? Well, it may not be so simple as that if you are in the growth zone (for girth) you have a thicker flaccid….it may be that a thicker flaccid helps PRODUCE the girth gains!

As I think about it, I think we can basically divide the penis into two types of structures in terms of gains ( this is simplistic,so don’t break my balls over it).

One is the tissues that are inflated by blood and the second is the ligaments that limit length and give structural support.

For girth gains, we need to increase the size of the tissues that are inflated and or increase their number.

I am starting to think that keeping them partially inflated for long periods of time AFTER stretching them is critical.

Many, many of the guys that get improved girth either notice a heavy flaccid all day…or CREATE a thick flaccid with something like thera-p wrap.

I think it is good to think in terms of hanging, that many times after heavy hanging…many find if they do light ADS…it accelerates progress for what ever reason.

I think for girth it is vital to keep a heavy (thick) flaccid for long periods after the expansion session (pumping, clamping, etc.).

Further,it is CRUCIAL that you aren’t using so much force that you are getting a contraction reaction…this would obviously have the opposite effect of prolonged partial expansion.

I find if I can keep my flaccid thick most of the day…without significant stress to my unit…that’s when I am seeing real girth progress.

If I find I am contracted (thin) during most of the day…girth will start to decrease.

Big Girtha has done some interesting research (on himself) in this area. He finds that if he takes 30 mg of Cialis once a week, then does girth work for those first 3 days…he makes his best progress.

What does the Cialis do? It allows him to maintain a heavy flaccid during abusive girth work that would normally cause contraction.

Now I know it is possible to do the same thing without Cialis, you just have to find the right amount of girth work that expands you during it, but doesn’t result it contraction afterward.

So heavy expansion followed by rest in a partially expanded state….are you seeing it?

Anyway, that’s what I am experimenting with.

I am trying to find the optimum way to alternate or add moderate hanging with pumping for the major expansive exercises…and follow with PE wts and Thera-p to do ADS and ADE (all day expansion) for the supportive PE exercises.

One last note, if I use too many PE wts, it will stretch my unit out and it will be thin. Which is fine for length gains primarily, but I want girth also.

The trick is to use as much wt as I can while still maintaining a expanded flaccid (thick) from the Thera-p wrap.

So maybe keep it in the pump at 1”Hg for an hour, then two hours…?

Let’s hope a slightly increased FG helps growth. I’m wearing my ADC all day and, so far only once, all night. (Disclaimer: Sleeping with too much constriction can kill your unit. I built it up very slowly, first 10 min, then 30, then 60… and the strap at this button hole barely constricts; still I’m taking a risk.)

Start: 6.3 x 5.2 (Feb '05)

Now: 7.9 x 5.65 (gain 1.6 x 0.45) - SFL 8.6"

Goal: 8.5 x 6.0 - Currently trying: handclamp squeeze, O-bends. My data - Progress log

Ok, here we go…update time.

I was making good progress on length, but noticed my girth was sliding back to where it was…why?

I was no longer coming out of the tube heavy and thick. I increased my time to 4 sets of 10 minutes…still with heat, and really not expanding much…WTF?

I even went to 4 in hg, with brief periods (30 secs) up to 5 in hg. I have tended to avoid 5 in hg or more, because I start to get blood spots in the skin.

Still no real expansion…now I’m confused.

After examining my notes (recently started to write down EVERYTHING) several things stood out that I stopped doing.

I had been taking 7 mg of liquid cialis about every 3 days, and I had stopped to get a true read on my progress.

The other thing was I had been doing occasional water pumping.

I had also been doing the thera-p and ADS and occasional hanging.

Ok, lots of variables here, but I have been sorting through them and thinking… A LOT!

This is what I’m thinking now.

The cialis for me acts as a steroid for my dick, not that it accerates healing, like anabolics, but it keeps my unit partially inflated ALL DAY!

I am really starting to think that that partial inflation is really the ADS of girth!

It keeps the erectile cells partially expanded long enough for them to heal in the expanded state and grow.

Just like a small wt used( for long periods of time) after a heavy wt has stretched the ligaments.

When I add the thera-p to that it really supercharges the effect.

It seems that during a few good sessions, I had expanded the girth, and didn’t do enough to continue the expansion, or even MAINTAIN it…so I was slowly returning to the baseline.

The other factor was I revisited water pumping with my new tube (2.25 in) and holy crap, even with low vacuum of 3-4 in hg, it expands me almost to the sides (even accounting for optical distortion).

So what I have done is gone back to 7 mg cialis every 3 days, and now have switched over to water pumping.

I have now almost gotten all my girth back.

The great thing about water pumping is that it exerts more force in girth than air pumping, therefore you can get greater girth expansion with less vacuum.

It has to do with the non compressablity of water.

Anyway, I’m gonna try going back to 3 sets of 5 minutes at about 3 in hg with the water pumping, add back the cialis and I will get back to you.

I am firmly of the belief that progress should be seen on almost a day to day basis if you are “dialed in”.

If you are not getting progress at least by the end of the week…change your parameters intelligently.

The definition of crazy is to keep doing the same thing and expect different results.

Its bad enough we are all a bunch of obsessed dick pullers…lets not be CRAZY obsessed dick pullers! :)

sparkyx, Sorry to hear the gains were temporary. Same here: only my initial 0.2” EG are solid. I myself keep jumping from one idea to the next. Right now, I’m thinking long-term, slow conditioning to pumping, so perhaps eventually it will result in permanent gains.

Start: 6.3 x 5.2 (Feb '05)

Now: 7.9 x 5.65 (gain 1.6 x 0.45) - SFL 8.6"

Goal: 8.5 x 6.0 - Currently trying: handclamp squeeze, O-bends. My data - Progress log

This is how I see it.

Our efforts must fall between these two parameters…

one, they must be enough force to see at least some expansion when we are done with pe(right away)…

two, it must not be so much that you cannot recover enough for the next productive session.

This means ( in my mind) that if you are not getting decent expansion during your pe session…its not enough!

If you get decent expansion during your pe, but you end up losing size…it may be too much force or not enough recovery time.

So the first step is adequate expansion…if you don’t use enough force/time to get expansion…WHEN will you get bigger?


It doesn’t make any sense if addition forces more than a normal erection isn’t expanding the tissue, do you think a normal erection will?


So within that requirement, you have to see what gets expansion for you.

What I can say is overall, heat makes the tissue more responsive to expansion for most people.

Next is forces and time.

The limitation of pumping is lymph migration and tissue damage (blood vessels etc).

We know long periods at high vacuums will get expansion, but many times lots of lymph and blood vessel damage can occur.

So what you have to do is experiment.

Find the levels that damage starts at…for me its 5 in hg….I get red spotting starting at that level.

Now there are factors that alter that. Condom pumping and water pumping allow me to use 5 in hg fairly safely.

Next is the time factor, it must be enough to get expansion while limiting damage and lymph migration.

All these factors should be guiding us toward some sort of reasonable starting point.

So lets say, 3 sets of 10 minutes at 4 in hg are well tolerated, and you get fair expansion.

The next thing is…do you get contraction reaction…and how long does it last?

Maybe the 3 sets of 10 minutes at 4 in hg gives you good expansion, but the next day you are smaller…but 2 days afterward you get a good fat flaccid hang and your erections are good.

This would be a good starting point…to stay with until one or more of those parameters no longer work.

I changed because I found I stopped gettting good expansion during my pumping.

I am now altering my pe in order to get that expansion again, then I will observe the after effects to determine if I should do less or more, or more often.

My gut instinct is that a routine that can be done frequently will be more productive than one that can only be done once every few days.

All I can say for now is that I am approaching it scientifically and hope one day to be able to give a systematic way for anyone to determine their own best parameters to get optimum growth.

I just hope I live long enough to find it! :)


from a physics standpoint, your explanation of why water pumping is better than air pumping just doesn’t hold water. So long as you are in some kind of fluid medium (either a liquid like water or a gas like air), the force exerted at a given pressure (or in this case vacuum) is the same for either. This means that 1” Hg in water exerts the same forces on your penis that 1” vacuum in air does. The compressibility difference means that it will take less pumping to create the vacuum in water than in air, but the forces on your penis are the same.
