Periodic high vacuum pressure pulses during a low pressure session

I experimented with a low vacuum pressure (5 inHg) routine with two 2 minute pulses at 20 inHg.

The hypothesis of this test was that perhaps a small amount of time at a high pressure wouldn’t trigger the contraction response and would add to the cumulative expansion of a 20 minute pump session.

The result was that it did trigger a contraction response. While it did produce an increase in post pump size, it caused a small reduction in the erect length the next 2 days, so far. I’ve been stable at 9” and over erect length for a while, but it is now measuring about half way between 8.75” and 9” when erect. I expect this prolonged contraction response is similar to the response I get from high force extending and hanging and will not persist for over a week, which is why I’m not changing my signature just yet.

A setback is something I’d like to avoid, but I think this will be useful in clarifying my ideas about what triggers the contraction response. There is a gap in fully testing out the main hypothesis I’ve been running with to decide what to test, which is that chronically triggering a contraction response is what causes a plateau, but that’s something I’d rather not test out myself.

I think after such a long period of experimenting with so many different routines it might be time to go back to what has worked best in the past. I’m still not confident I’ve reached my girth goal for beginning the girth to length conversion experiment, it could be another week or two until my girth measurements are consistently at or above 6.25” and I’m playing with the idea of going to 6.5” mseg since, if the hypothesis is correct, it would give a more pronounced increase to the length gain rate and leave less room for me second guess whether the results supported or disproved the hypothesis. If the girth to length conversion test goes well, I’ll probably buy a smaller diameter tube to speed up the process of reaching my length goal.

Did experiment in a same manner (18 inHg pressure spikes), but didn’t follow the routine.
For me it was a curiosity or ego thing to pump up to extreme pressure spikes.
Fortunately I found better suited routines for my goals with much better expansion rates and less risk.

I shifted focus and only concentrate on volume now.
My experience with this approach is that both and length gains are possible in the long run.

Atm I am working on a new style that is working very good so far ( US hardcore warm up, pria pumping and pulse pumping with very fast pulses as main exercises).
I am gaining and thinking of using it for a new IPR cycle in the future.
This would be my master piece in efficiency ;)

I thought a lot about posting the routine since it is much better than any other routine I tried before.
Unfortunately I don’t want to share this style because I know a lot of people would injure themselves when trying it. I used to be a “trust person” in a german pe forum and helped a lot of guys.
Therefore I know a lot of guys would do it in a wrong way or be going overboard.
Compared to normal routines the consequences would be severe.
Moreover nobody knows about the long term effects of US use (that is why I stopped posting in Kyrpa’s US thread).

You are are smart dude and could create a similar routine on your own without me going into detail ;)
It is worth looking into constricted exercises and combining it with US as warm up before pumping.
The expansion is so much better with US heat that I don’t use steady vacuum at all atm.
The pulse pump style helps me to reduce potential trauma in my sessions.
In the long run I will combine steady vacuum (7-8 min) and pulse pumping (2-3 min) in a set.

Combined with pria pumping I get:

-no fluid build up at all
- insane expansion
-long lasting temp gains (days !!! )
- no EQ variance
- fast gains
- I can get away with very low pressure in the pria pump and still get a similar expansion to clamping imo with less risk if done right

Maybe this could be of interest for you as I experimented a lot and you seem always curious about new approaches.

Interesting. Are you going to “wait and see” as to the high pressure pumping or do you believe it not beneficial?

You referenced your signature in this post so I reviewed it and noticed you mentioned you lost size from disuse. I’m aware of the concept of “use it or lose it” but curious if your disuse refers to no PE or to no or less sex?

I have also been experimenting with a more narrow pump diameter to focus on length. Still to be determined.

Knowing what to tell people is sometimes hard, part of me is happy I haven’t found anything that increases the gain rate while investigating chem PE since I don’t have to have that internal debate.

Focusing on volume rather than length or girth measurements is smart I think.

I’m phobic of higher exposures to ultrasound. I’ve just seen too many things liquefied in ultrasonic vats I guess.

Kyrpa’s methods worry me some, but he seems honest and far more diligent than me in evaluating PE techniques. Since periodic ultrasound became a modality of treating erectile dysfunction, and from what I can tell it works and is safe, people will be using it, the PE world is lucky Kyrpa is investigating regular exposure on PE gains for everyone.

I do have a few transducers around here somewhere, though I don’t know if they have the right specs for this purpose. Knowing my personality, I will end up trying this technique eventually. It’s almost a certainty given enough time.

I’m sort of expecting a time will come that someone suggests microwaves for heating the penis, because theoretically it will work. Which is not a good idea at all since heating with microwaves has been tried in the past in animal models and it’s totally lethal. That’s mostly why we don’t have microwave space heaters or use microwaves to treat hypothermia.

Priapism pumping does look interesting, it sounds sort of like the effect I get from tube packing with a tube that is too small where it seems like the pressure inside the tube itself blocks out-flowing blood through the dorsal veins. I have some silicon sleeves and cock rings, I may have to give this a try.

I will be observing if the reduced erect length persists, but I don’t think I will be trying it again. In the past I’ve tried things which produced a similar prolonged contraction effect and it seemed to prevent gains.

Disuse there refers to both. There was a period of time, about half a year, where I did not have sex or masturbate, and I also stopped doing PE for about a decade since I wasn’t making progress with it. I think not having sex or masturbating started the shrinkage, but I’m not totally sure since memory isn’t a perfect thing and it’s possible there was something else I was unaware of causing the shrinkage.

So you use the US heat only before the workout and it still works during the session?
While doing constricted pumping you basically quickly alternate between very low hg (2-3hg) and 0 for a few to 10mn and repeat sets, is that right?

Now that I have been kind of drawn in to this , I would like suggest some aspects.

In the US warm-up based pumping there is lot of emphasis needed for the first crucial minutes after the initial vacuum has been exposed. The maximal expansion should be achieved at the beginning and the rest of the set should be more of a cooling phase in this initially achieved expansion. The set or sets duration Pe_pe is using sounds to be correct.

Because the focus should be in the start of the set, therefor conditioning set or sets are needed before the US heated sets.
There is a analogy to my experiences with stretching with the US.

And going with the high forces via vacuum more than 10 inHG, there is lot to gain not using sudden peaks when introducing the negative pressure. Visco-elastic nature of the tissues will object the the expansion less when the vacuum is increased in slower fashion. High pressure pumping as it is introduced in this forum by some of the key figures is really not the optimal way.

What comes in to concerns you have been addressing in my work, I hope all could recognize and value the emphasis taken on safety of the protocols. I have been doing and continue to express these aspects a lot.
US can be used in safe way or in hazardous way, and it is up to user to concern the risks involved.

There is lots of hazardous stupidity seen in PE long before the US had ever arrived in the scene, and some of the known “artists” will continue to promote it.

My length is back in the range it was before now. It does seem like there’s a tiny bit more toughness in the penis now, but that might just be my imagination.
