Gaining volume with Kyrpa

Commendable effort Kyra. Keep up the good work!

Thank you my friend and collaborator. Have you done any experimental work lately?

Or out of the box thinking as a peer to peer review of on-going processes.

I am starting my next length elongation campaign in two weeks and I am emphasizing more on the strain rate control this time.

Still based on the established protocol but ramping up slowly and in control with each loading interval.


START 18/13.15 cm Jul 24th 18 (7.09/5.18") NOW 22.5/15.2 cm Fer 12th 20 (8.86/5.98") GOAL 8.5"/ 6"

When connective tissue is stretched within therapeutic temperatures ranging 102 to 110 F (38.9- 43.3 C), the amount of structural weakening produced by a given amount of tissue elongation varies inversely with the temperature. This is apparently related to the progressive increase in the viscous flow properties of the collagenous tissue when it is heated. (Warren et al (1971,1976)

I’m excited to follow the next gaining period in real time:-)

Kyrpa, please tell us what we can do to help you.

My latest understanding was that it would help you if we collected different load strain curves.

That is why I did my personal one. I also have a log ond PEgym and got in contact with a good guy who was very interested in my log there

(because of the great techniques I used from your thread).

We are in good contact and he also did a personal load strain curve with the lg Hanger with my instructions.

I sent you the data and the link in a message with the obvious title ” another load strain curve for our dataset :-) “.

Please tell me if that is helpful for you in any way.

I say this because this is your thread and I dont want to dilute it with my posts, but if that has some value, I’d be happy.

All the best.


[before PE] Start BPFSL: 17.6cm (6.93 inches) start BPEL: 16.7cm (6.57 inches)

[currently decon until aug 2024] latest BFPSL: 21.2cm (8.35 inches) latest BPEL: 19.5cm (7,68 inches) latest NBPEL: 17cm (6.69 inches)

I think you’re very wise to focus on strain rate control. I’ve added a 1rpm motor on a foot switch to my device. This frees up my hands to control the heating without worrying about strain rate.

Right now I am battling a conflict between slow strain and excessive time under tension and heat. I do not want to exceed 60 minutes in a single protocol as we’re already confident that cell viability will suffer which theoretically hinders gain rate. However, from the viewpoint of achieving maximal strain in a single session, I would need to combine slow strain rate with a cyclical strain procedure. At least 4 or 5 strain cycles is optimal, but at the current strain rate, that would take about 2 hours. I’m open to your thoughts on variations to achieve the objective.

One part of me thinks I might be over emphasizing the downside of long sessions. We would dramatically benefit from others here taking on a portion of the experimental method. But I don’t want to be the one to encourage them to abandon your more proven protocol just to give me more data points in changing the optimal. And quantifying cell turnover and apoptosis isn’t possible with our current equipment. It is fair to suggest that more than 30-40 minutes under intense heat isn’t good. So I’ll need to limit the heat phase just to the last 5 minute portion of each strain cycle. This will undoubtedly increase tissue trauma versus the current protocol that has heat through most of a single long slow strain.

Thanks for the well wishes. I don’t really have much interest in gaining size. But I feel we’re close to cracking this thing with very slow mechanical strain under deep heat.

I’ve spent a bunch of time theorizing and performing basic test on models of the intracavernosal pillars as the limiting factor for girth expansion. I do not like the current methods of inflation (pumping and clamping)
aimed at girth gains because both are problematic for heat application, discoloration, and risk of injury. Needless to say from an engineering perspective, the pillars are VERY difficult to target with sufficient strain while heated. Fortunately an individual pillar need only achieve permanent elongation of about 2/13 of the target girth increase, which in most cases here is only about 2-4mm. But that is still a problem given the structure. Basically it is just too strong. Bundled stretches do a good job of radially straining the TA, and RF makes heat application of a bundled stretch possible, but the pillars remain relatively untouched.

Can you share a picture of how you hooked the motor up. Love the ingenuity.

In the short time which I have preformed bundle stretches while hanging in front of an IR light with very nice results, the quest for girth still continues I suppose.

If there were some sort of Fleshlight-esk device which could propagate the Ultrasound waves properly, 🧐.
An Ultrasound oven so to speak……

I understand that 2 transducers could cancel out and negate each other. However, what if they emitted pulses alternating energy in sync with each other so that they would not negate each other. If they cycled through the process very rapidly, maybe there would still be a chance for sufficient heating……

IMO, there is no need to stay married to ultrasound. It is just one of 3 technologies capable of penetrating heat. What you are describing is better accomplished with RF and can even be accomplished contactless. Unfortunately, I’m not skilled in design of RF transmitters, and the contactless ones that currently exist on the market are designed for circumferential reduction of the abdomen; therefore quite large.

The small RF home devices might be somewhat useful, but I would need others here to provide feedback. I already spent a lot of money to get a clinical RF device, so I wouldn’t have a use for a home device.

I fairly convinced that a contactless RF device is ideal for all things PE.

Tutt if you don’t mind is there a minimum spec to be looking for regarding rf machines?

You will be looking for monopolar RF because none of the bipolar or unipolar machines are gonna reach the depths you need. Something in the 1-2 Mhz range.

It is difficult to state a target wattage because mine is like 300W max. Obviously 300W is absolutely huge amounts of power compared to what we see here with US. With this kind of power you can burn yourself easily if you are not used to designing controlled experimentation in a lab setting. Let’s just say I could cook a hotdog in less than a minute.

Keep in mind that regardless of modality, power is power. Whether that power manifests in the form of heat has to do with the frequency. With EM, it seems like 2Mhz is about the right frequency for a monpolar transmitter to reach depths of about 1-2cm. In general, higher power reaches greater depth, but it is really difficult for a bipolar transmitter to exceed about 5-7mm depths because the wave tends to conduct through the epidermis.

Comparing apples to apples, at max output my machine is at about 7W/cm2. Most of the US devices around here are about 1.5W/cm2. I typically end up using mine at about 2-2.5W/cm2. Target temps are reached very quickly. A few minutes.

You want a larger radiating area if possible. This delivers the power across a broader area, but keep in mind that even if you use a larger transmitter, the power will travel through a small contact point if it has to. Be sure to make good contact.

Two stage type cylinder full of water.
Several transducers. There is your oven.

Waves will travel through the water without needing the skin to transducer contact.

Tutt, very interesting. Thanks for sharing.

Kyrpa, hope I didn’t hijack your thread.
