Game changer study may 2022

Nice gomi !

Which to believe was pondered.

As far it goes for this study the finite tensile strength of tunica seems to be very low
The elasticity and the tensile strenght of tunica.pdf

With a seemingly similar setup for testing, they end up in the 600 - 750 mmHG bracket which equals 0.08 to 0.1 MPa for finite tensile strength.

The new study comes closer to reality I believe, probably still indicating significantly lower than real-life values.

It is very much up to the preparation of the samples, attachment to test equipment, and most importantly the strain rate used in testing.
It makes a difference if the tissue sample is pulled at high speed or with a very low strain rate.
The tissue is not fully elastic and should be treated considering this.

So if you ask me none of these studies can´t be taken without a grain of salt regarding the finite tensile strength.

For the elastic modulus, this thesis produced numbers between 20 to 40 Mpa with significant variation between samples.

As the previously mentioned study above, a whopping 100 MPa. The method used to determine the modulus in this one can be questioned though. Not sure if it is the proper way for this kind of biological material.

As the numbers are all over the place, I wouldn´t believe any of them are confirmed.

One thing I will take from this study is the inflection point is confirmed to be at the level already seen in the thesis above.
The start of the elastic range. Which by the way have been able to replicate with penises at this forum already.
I firmly believe the finite tensile stress is irrelevant for penis developers as there is simply no need for reaching such stress levels.
If the growth happens at the start of the elastic range, who the hell needs to reach the other end?

Kyrpa,

Given that this is the only information available I would agree that one must take it with a grain of salt. Let me expand a little on this and that way we can find some common ground.

The fact we don´t have a definite study opens the door to empirical evidence. If one digs into this and any other PE forum we start to see some pockets of knowledge that repeat over and over. For example, we have seen all kinds of methods get results so we can assume that most men that attempt some type of PE will get what we all have come to call “newbie gains” that for most might be from half to two inches. That alone s great news for the majority of the PE practitioners. Obviously we have the outliers on both ends of the bell curve with either no gains at all as well as incredible gains. I only mention this because there have been many methods posted on these forums over the years the promised to be the next great advancement in PE ridding on the coat tails of those “newbie gains”. Just think about it, just about anything will work for these initial gains so I am sure more than a few marketers out there found a great way to make some $$ by selling hope to some guys knowing full well that was almost guaranteed to get some gains. I know I might have gone off on a tangent here but I want to give you an idea of why I say certain things.

So here is what do know.

The elastic range: The range of stress values at which a material’s deformation is temporary, and it returns to its original form when a force is no longer applied.

The plastic range: The range of stress values at which a material’s deformation is permanent, and it no longer returns to its original form when the applied force is removed.

The use of the word “grow” is misleading. You can deform but you can´t grow your penis. Sure it is longer but it was deformed.

So that brings me back to just needing to enter the plastic region to get the permanent deformation. You don´t need to go all in to get the benefits of the plastic range. Yo just have to enter the initial part. Think about it as entering a house while it is raining outside but you don´t go beyond the foyer. You enter the home but you didn’t go all the way to the point that you know all of the rooms within the house. If all you wanted to do is not get wet you accomplished it without having to go much beyond that entry door.

And this brings me to the empirical evidence of the last 20 years. When you look at most of the big gainers be it jelqing of hanging you notice that the amount of tension or weight was, in most cases, substantial.

Mind you that you can gain in the elastic range but these gains will eventually stop and most likely are within the newbie gains I mentioned above.

Take a look into newest information of tissue expansion. Any tissue. It is indeed growth they can found when the ECM is stretched.

You can’t deform the collagenous tissue into permanent elongation with the low force applications like extenders.

The load is simply too low. Yet there are gainers with permanent elongation. It is not a direct result of collagenous material deformation. The structure has grown.

What is tunica hanging? Do you mean across the shoulder or upwards?

There are several studies on mitosis, which is induced with particularly long periods of stretching (ads comes to mind, extenders, or other long exposure methods). Combining tensions (high-mid-low) in order to achieve the most hours per day, including alternative ways to keep it stretched during sleep (sleeves comes to mind, for as long as they are not constricting the blood flow or complicating sleep-time erections). A week on the 24/7 program and you will notice a difference in growth rate. then you can go back to a lesser routine and the chemical reaction will linger two to three weeks in my experience so there will be a growth spurt. Actual cell replication growth, as opposed to plastic deformed. Of course there will always be a little plastic deformation when stretching the dick. But mass WILL augment too.
Why combining tensions? because higher tensions will create more inflammation on the tissues while mid tension will make body release anti-inflammatory biochemicals, so the sweet spot is 15 to 20 minutes on my case of high tension then the rest of the hour at mid. However these numbers might change from person to person, particularly with the load applied. I am somwhere between 2,5 and 3,5kg tension on my extender at max tension. But you might be hanging 10 kilos with no sweating at all. So there’s that.
I’d be using a hanging device if I could only get my hands on to one, but my country is so third world, I just gotta thank to be able to use internet. haha

Kyrpa, when I think “growth” I think replication of tissue. To me expantion or stretching is just another way to say deformation. The penis stops growing up to two years after we reach adulthood. Only place I have ever seen tissue growth is in lab experiments.

What you see in the PE community is just the stretching or deforming of the penis and surrounding structures to achieve a desired length or girth.

Just to add to this,

A surgeon can perform one of two approaches to limb-lengthening surgery: by applying pins and a frame outside the leg — called an external fixator — or by inserting a nail, called an intramedullary nail, into the bone. The nail can be lengthened over time to support bone growth and elongation.
Yet this type of procedure cannot be done after the growth plates close. That is around 18-25 years of age. Even with this you are not going to get muscle growth around the lengthening of the bone. You will have it stretch.

I would like to read any study you have on hand that explains the opposite of what I just explained. It would be fascinating to read.

In all cases of hanging the tunica is getting stretched. I still believe that you can put some emphasis on the tunica but then other factors come into play.

Let me try to make this simple.

The bro science in the PE community is that BTC or SD will target your ligaments the best. This is kind of common sense given you are stretching opposite the origin point of the ligament. Simple biomechanics. You are still stretching your tunica but according to bro science not as efficiently as other angles.

Straight out or incline is what PE Bro science says is the most effective angles for the shaft/tunica. You would say that it is logical but lets take into account that at that angle you have all the penis structure working together. Tunica, ligaments and skin will all take on the load. Logic says you would require more weight to counter the extra involvement of the skin and ligaments.

Finally, inner shaft is straight up or OTS (over the shoulder) as the more effective angles. I tend to believe the same logic is applied as the SO/ incline.

So what do you believe??

My take is that BTC/SD will have an increase in tunica stretching effectiveness as the ligaments and skin eventually find their max stretch point. So in a way BTC or SD would be the ultimate tunica stretcher given you deplete the ligament and skin.

Primero, excelente post. Me gustaría ver los estudios de mitosis si es posible.

The tunica has the most potential for length gains. Lig stretch seems too have some.

Attachment matters a lot. If a guy attaches hanger 3/8 toward the base , that’s not halfway. If one attaches 5/8 , that’s more than half toward the head. Closer to the head targets more tunica, however it’s more dangerous, if technique is off. Too close, no less than 1/4 of an inch from coronal ridge.

I think straight out puts more tunica stress than BTC and SD. I think straight up targets tunica the most.

So how many times should we practise in PE?1hour?2hours?And so on?

Seems that 10-14 hours a week was the old school PE rule.

Thanks for sharing this study, limited it may be, but helps explain a lot of the physiology of what’s going on. Also, the comments about angle and attachment location are enlightening.

Lastly, I would love to try to find a way to wear my ADS for a week straight! I don’t know how you would do that, but would love the challenge. I’d have to convince Mrs W10 to take 3 little kids for a week, and be mysterious about what I’m doing! 🤣 I don’t like being that selfish with time.

Gomero, I believe once permanent elongation has been achieved, there is along process of ECM reorganization which includes recruiting of satellite stem cells for growth of new tissue. Also in your example of muscle, there is plenty of science on the effects of IGF-1 and muscle hyperplasia, ligament and connective tissue growth. For years I have been reading about these topics looking for the ultimate protocol. There are some novel protein and enzymes that we could greatly benefit from such as BMP proteins, SHH and others but we need the knowledge and infrastructure in order to properly prepare them for us.

Use of an ADS beyond 4 hours is counter productive. For what I have read over the forums is that it might be 50/50 on the use of ADS to supplement the hanging routine. 50% is better than nothing so might as well go for it since you might be one of the lucky 50% that it benefits. Another point to add to this is that there seems to be a point of diminishing returns on how long you use the ADS. Seems like 4 hours gets you the same result as 8 hours so hopefully just saved you some time.
