The characteristics of the tunica albuginea revisited

Yesterday I build a cheap pump to see if clamped compressed pumping could work.
The idea was to emulate a squeeze session with this construction.
My goal was to manipulate the tunica in a efficient way and taking the guesswork out of the exercise so it is easier to replicate than a manual exercise.

I measured a 3 mm gain after the session and a 1 to 2 mm gain after 24 hours at different points on the shaft.

A squeeze session done 2 days beforehand to create a base line produced a 1-2 mm gain after the session that was lost after 24 hours.

In comparison the compressed clamped pumping was less harsh to the tissues and my penis did not feel worked out in a negative way compared to the squeeze session.
My erection quality wasn’t compromised at all using the new approach so I will continue as it seems promising at first glance.

My setup was pretty easy to build and will be improved if I should follow this approach.
But it should be sufficient as a first prototype and be enough to rate the efficiency.

The construction simulates a squeeze that produced girth gains for me in the past.
So I took a BPEL measurement in my squeeze session from the base to the coronal ridge.
The measurement was done just a tad before length elongation kicks in and at the point when my girth expanded the most without resistance of my tunica walls.
This happened at about 50% erection level.
In general I do my squeezes at 70%.

The measurement was 12.5 cm. My BPEL is 18.7 cm at the moment.

Then I used a very narrow pump sleeve that is very tight and rigid at the base of a 2.5 inch pump cylinder.
The rigid sleeve starts to clamp at low erection levels.
Some cheap 4 cm pipe insulation was used as a compressor.
It was cut to a length that my shaft couldn’t grow more than 12.5 cm in the pump.
I wrapped a self adhesive tape tightly around the glans to squeeze all the blood out of it until it is really small.
The pipe insulation was sliced for a couple cm so it is easy to put the wrapped glans into it.
When the glans is inside I used some tape around the insulation to close the gap of the slice.
The glans sits very tightly in the insulation and can’t expand at all.
Then I started to pump and kept the pressure at 80-100 mmhg for 15 min with a short break in between.

It took some minutes to get some expansion in the shaft because of the clamped base, but after some time the shaft compressed nicely against the insulation without any discomfort.
Because there is no discomfort I think longer sessions could be done or shorter sessions with higher vacuum levels as well.

I will continue to experiment as my first session seems very promising.
Lets see what is achievable long term with this construction.
In the future I would like to install a FIR foil inside the cylinder and prolong the sessions to 40 min.

It would be interesting if there is some science to back up the idea or to improve the sessions (I.e. Time, pressure levels or construction).

Hey Kyrpa, Tutt, or others,

Would you have any thoughts on my current girth routine? As Kyrpa recommended I am doing a 2 months length, 1 month girth, 2 months off schedule and I meant to come back to get more details figured out about the Girth portion of that mesocycle but just ran out of time and before I knew it, it was upon me!!

As I read the thread and try to figure out how to take action on the information, I am doing 2 days on, 3 days same as with length of the following:

2-3 sets of penile bodybuilding
Then 3-5 supersets of:
A. 5-8 minutes Heated Pumping.. starting low pressure, building up to only moderate pressure (especially earlier sets) heated w/ heatwrap all around tube (gets very warm)
B. 5 minutes Manual Clamping as my unit cools, with some natural squeezes involved. I maintain enough constriction to assure that the skin is taught at the head at all times. I’m sure you know the look.

My basic reasoning at this point is trying to apply a very crude approach to girth that we applied to length: the gradual increase of tension/pressure with the assistance of heat, and once a certain point is reached, to allow the unit to cool in the new state. Please forgive the crudeness of it, I would love to sophisticate this but haven’t had time to learn as much as I wanted to the last 2 months, so I have just been trying to do something. For me, keeping moving and at least trying something is better than doing nothing at all. Objects in motion tend to stay in motion :)

Side question, I do not believe I am capable of testing my BPFSL without overdoing it so I have just given up trying. Does anyone have advice for people like me who just repeatedly slip into the same overuse habits of trying to force things to work?

Hey Kyrpa,

I’ve been mainly following and reading 5.5’s thread and progress and of course he posted links to your thread here and I’ve been reading it too.

This is also really incredible stuff and I hope it works for myself and others.

I’ve been doing PE for some time now and I don’t think I ever made gains.

I stopped vacuum hanging in early December and had just gotten up to about 10 lbs which I am really hoping did not strengthen my unit to the point where the methods you, 5.5 and the others have laid out will not work. I don’t plan to try the method until February so I’m hoping those 7-8 weeks of Decon will make it possible. So this brings me to my first question..

Do you think I should wait longer than 8 weeks?

I know 5.5 for a while did 90 minute sessions but then I believe he went back to doing 60 minute sessions. But they looked something like this..

8 mins @ 24oz cold
8 mins @ 36oz cold
15 mins @ 36oz heat
15 mins @ 54oz heat
30 mins @ 84oz heat
15 mins @ 96oz cool down (pad removed)

And then later

10 min @ 24oz stretch
15 min @ 36oz w/ heat
15 min @ 54oz w/ heat
15 min @ 84oz w/ heat
10 min @ 102oz cool down

When I measured for the load calculator I believe I could 100mm girth right behind my glans so I believe I can use a pretty similar weight range as 5.5 (who I believe had 97mm)

Would my revised session look something like..

10 mins @ 1.5 lbs
15 mins @ 2.5 lbs and begin applying heat
15 mins @ 3.5 lbs with heat (should be reaching ideal temperature? Based on what I’ve read in 5.5’s threads)
20 mins @ 5.5 lbs with heat (should now be the ideal temperature for the whole 30 minutes)
10 mins @ 6.0 lbs (or maybe 6.5 lbs?) with the heat now removed and the unit having 10 minutes to cool down in the slightly more stretched weight?

(The weights I have may be 0.5 lbs each. I tried weighing one and it said 7 oz which is like 0.4375 lbs so I will need to find a better way to confirm the weights. But it may actually be better if they are 7 oz and not 8 oz/0.5 lbs.)

I like to have a larger heat pad, its almost like a heated blanket, over my waist sometimes when I’m sitting down at my desk. I’ll be clothed so its not directly contacting my unit. I should be safe right?

I think your plan is spot on and I plan to do a similar routine starting in February when my heating pad arrive.
You might start a little lower in weight for the first sessions to see witch strain % you reach.

Please advise on the measurement for the calculator. Is it necessary to move the foreskin? It makes it thicker. What are the N and Lbs parameters for?

When I measured, I wrapped the tailor’s tape around enough to make it taut, just enough to compress the skin a little. I’m not sure how others are doing it, but I figure that is good enough.

N is newtons, a measurement of force. It is mass times acceleration. In this case, the acceleration is gravity, so 9.8m/s^2. Divide newtons by gravity, and you get the kilograms required to exert that amount of force. Lbs is the weight in pounds.

Do I understand correctly that the suggested weight in the table is the maximum weight per workout? That is, with a thickness of 10 cm my weight should not exceed 2.38 kg?

Is this the maximum weight when using ultrasound? Or already when stretching manually?

Thank you.

Check out 5.5Squared’s post. He does a real good job describing how to apply this approach, when to add weight and heat. The high level summary is this, as far as I understand it.

1. Use calculator to find necessary weights at .1MPa (non heated max) and .17MPa (heated max).
2. Incrementally load weight to your .1MPa max over period of time.
3. Add heat and begin incrementally loading of weight to reach your .17MPa max over a period of time.
4. Begin cooldown portion of the session by removing heat, and adding 20%-25% more weight NOT incrementally. Hang at this weight a period of time.

Hanging with FIRe

Outstanding work Kyrpa!!! I can’t wait for time to read the newer study. You’ve been an invaluable member here, if others can’t see that or are afraid of new ways of understanding that is their problem. It’s time we get more quantitative and learn to use our time and resources efficiently.

Yes, this is it! Good explanation. I want to add that the load calculator is like a guideline and is based on your flaccid girt. Small girt means you will need lower weight to reach .1MPa and .17MPa and big girt mean more weight. It can be wise to start at lower weights than the calculator says. The main thing here is to reach 2-3% of BPFSL strain per session with as low weight as possible.

Thanks for responding.

I really want to make sure I do this right so I may even wait till Mid February before I start. Which would be 9-10 weeks I believe of Decon.

I have my TherMedic heat pad and my weight situation worked out. Need to get some supplies to make a pulley though under my desk.

I haven’t tested the TherMedic heat pad but I trust that it works and in case it doesn’t I’ll have the TotalMan one as a back up to use if I have to.

Hey Kyrpa,

How do I know how much force I exert on my dick while jelqing. Is there a way to determine I will stay under 0.17 MPa.

I only do supplemental jelqing 3x per week at 12 minutes. 100 jelqs, 1 jelq takes 5 seconds to do.

Besides this I am in the process of lengthening my TA with the Ultrasound therapy hanging sessions.

Check this out.

What it comes down to in the end is that the physics of bundled stretches maximally stress the longitudinal tunica, modestly stress the transverse layers, and cannot stress the pillars at all. The latter IMO being the biggest limiting factor to girth gains in the end.

That’s a good setup if vacuum was optimal, but unfortunately vacuum simply isn’t great. It does create some TA strain but simultaneously creates fluid buildup in the dermal layers. Much of the girth increase reported here is actually just temporary swelling of the dermal layers. Under higher pressures it can be so excessive that the dermis detaches from the supporting structure with massive fluid build-up. Also staining is a common problem. I’ve heard women mention about a guy I know that they knew he was a "pumper who tortures his dick" because he had so much permanent staining. Not really the look we should be targeting here.
