Manko007's road to big dick land

So am I getting this right? Going through cycles of stress on your penis will eventually cause the resisting fibres to fail, leaving you with breakage and resulting in length gain?

When it says cycle, does it mean how many rounds or times you pull and hold in a particular direction?

With the stress load, I am trying to figure out which is better, high stress or low stress load, or sequent starting at low then high the more cycles you go?

Essentially yes.

And yes that is what cycle means. 1 repetition essentially. Like at the gym, one rep. One stretch of 30seconds. Then release and rest for half the time. Repeat. 30 cycles would be 30 reps etc.

To determine your optimal stress load you want to start a log and record your BPFSL numbers. You need 3-4 BPFSL numbers depending how many sets you do. Some just take 2 BPFSL measurements, beginning and ending.

I use 4 because I do 1 precondition set. So before anything I take BPFSL 0. This is before starting. Say it is 21cm. Then I do preconditioning 30min at 3kg. I take BPFSL1. Let’s say it’s 21.3cm. This BPFSL 1 will be your elastic limit. Essentially this means you have taken the elasticity out. This can also be called the “toe region” part of the stress strain curve.

Then you do your 1st set. For me I do 20min hang. I used to do “static” hang for my macro cycles 1-3, which means continuous weight. I increased the weight as you can see in my spreasheet. However, now I will incorporate the cyclic stretching/hanging because of theory 2. So I do US and IR for 10min. Then I cyclic hang with weight up to 8kg so far this cycle 4 for 10min. After this set is done I take another BPFSL 2 measurement. Let’s say it is 21.5cm. This is already in the transition region of the stress strain curve. AKA the “elastic region” maybe even in “plastic region” a little. Who knows.

Then I do one last set I heat for 10min IR and US and then manual stretches 30 secs on 15 seconds off, which is about 12-13 “cycles” at max grip power. I use my other arms wrist to fulcrum the shaft as well. Then I take the last BPFSL 3 (or T3, t is for time) and lets say it is 21.8cm. This I believe is in the “plastic region”.

You can see the attached graph for reference.

The point between the toe region and the elastic region I believe is called the “knee”. So you can find out what your Knee point stress is, what your yield point stress is (point between elastic and plastic region) and use those stresses accordingly.

But you need to log your numbers so you know where you are operating in the curve. Otherwise you can’t find out your ideal stress.

To answer your last question, use both. Low stress to precondition, which means attain the elastic limit or knee point. Then up the stress to attain yield point. Then you can increase further to obtain the plastic deformation. I do 3kg, then 6kg, then manual stretch or 8kg.

Increasing the weight over the cycle based on studies of hysteresis has shown to move the curve to the right each cycle as well. But so has using the same stress. So I would just use the same stress because you can record it easily.

When you load up to your stress do so at a slow rate of 1% to 5%/s of max load to minimize stiffness when loading. This means if your max load is 10kg, do so in 1-5% increments. Let’s choose 5% because it is more practical. You would increase 0.5kg/s until you reach 10kg. This means it will take you 20 seconds to load to 10kg to minimize stiffness. I respect this principle particularly during my precondition and 1st set. Then I feel the stiffness is not important and for cyclic stretching the loading rate is quick, or as comfortable as I want.

Attached you can also see a graph of hysteresis, which is the effect that happens when you cycle load something.

That’s pretty detailed. Thanks for explaining that for me. So am I wanting these ligaments to break/fail?

Can I potentially break my penis from over stressing/straining it?

Well no one is really sure what happens at the micro level but there is speculation that yes you do want the collagen links to rupture, slip, or elongate.

Whatever the mechanism is the evidence points to permanent elongation if you follow a routine focused on maximizing your BPFSL.

I would not think you would be able to break it, perhaps if one were to attach a ton as a stress load. But the max I’ve heard was 100lbs.

Of course exercise caution and don’t be too wreckless. These studies are done on dead tissue. We are working with live tissue here. So we must be more mindful of the stresses we use and the periods always ensuring good blood flow and care is taken to not wreck your unit.

I would say if you are begining this may not be a good place for you to start but definitely keep in mind for when you are more comfortable in the workings of PE.

The study you referred is read freely in here https://onlinel ibrary.wiley.co … %2802%2900028-1

I posted a comment on original context in my log.

There are interesting simiilarities with the data I have gathered and the study concerning low stress cases and the non-linear behaviour of the viscoleastic tissues.

I’ve ordered a IR heat lamp on eBay, I should get it in a month. I’ve just been manual stretching in the shower and doing cycles as a way of hearing my unit. I can feel the strain when I’m pulling as if it was becoming fatigued. I am practicing this stress relaxation and holding it for a few seconds. So I pull for about 20 seconds and then hold it a little longer to stress it at its max and then switch. I do this a for about 4 cycles and then do some jelqing. I find that once I do this type of program my unit becomes very long and relaxed, unlike at first where it seems to be engorged a little and plump. After I stretch it out I see it hangs low and thin sort of due to being stretched and strained. Once I reach this point I pull and hold a while, keeping in mind to get all angles in order to stretch the ligs too. I’ve pulled one leg up and rested it on something in order to accommodate a good lig stretch while getting a good angle and stretch. I find that after a session, my unit cannot get hard even when I Due to the stress and strain I’ve put on it. By the end of the day it’s back to normal

Does this mean I’ve done it right?

Nice lol I was going hard way around

Sounds like you are mostly manual stretching which = cyclic stretching in context. So I’d say you need to work on “preconditioning” or “stress relaxation” or “delastifying” which means for 20-30min at constant load of 2-3kg or less for you maybe 1kg, extend with an ADS (all day system) like a vac hanger, or a bib hanger, etc. So you can take out the elasticity out of your dick. Then you can do your manual stretches and then you will be entering the more plastic territory that will create permanent length gains. Log your data! Be careful after ADS as your dick won’t have the elasticity so any load that is beared by your dick will not have any elasticity as much, so it will be more sensitive to load.

Today had a good sesh. The main improvements were actually in basic things:

Improving hanger attachment. Revisiting BIB’s (Bigger) guide and also searching forums for improvement.

Here are my guide points which drastically improved grasping of internal cords and comfortable, and caused significant more strain:

“improved hanging technique. Wrap 1 inch behind coronal ridge. Hanger 0.5inch behind wrap edge. 1 thumb between hanger and coronal ridge when tightening. Place shaft all the way tro bottom of canyon. Push pull while tightening. Wait 5min to condition to hanger and create shoulders. just use therawrap and pain killers
wd40 on wingnut. squeze blood out of head.”

Basically what I wrote down on my spreadsheet under 21.8 BPFSL 2 as a comment to remember always to do this.

After this I managed to surpass BPFSL 3 from 21.8 to 22.2cm. Coming back baby

Now the main takeaways from this sesh were that:
-cycle hang first then static stretch (this is for steps after precondi) 10min non heated
-reasoning is that fatigue shorter fibrils first to then statically load the hell out of them 10min and heated with US 1mhz

Loads were 4kg for precond. Also used some heat here because I was going to start with cyclic hanging later, so I wanted to reduce even more elasticity in tunica.

Another thing about cyclic hanging first I read cyclic stretching helps to dissipate or eliminate the viscoelastic properties. And then it is much easier to stretch thereafter. Think about a party balloon, when you simply go to inflate it the viscoelastic property is strong. However, if you stretch it a few times back and forth ala cyclic stretching, then the viscoelastic properties are eliminated, then when you go to inflate it it is alot easier.

Same principle applied and seemed to work nicely, but more data points need to accumulate to prove it.

6kg was used for first hanging set cyclic set. Then 6.5 and up to 7.5kg for remainder. It was all mixed up in the end between static and cyclic, but it was cyclic without heat, then static with heat and variably increase weight based on comfort up to 7.5kg recorded.

The elastic bands are wonderful. I can increase the weight simply by moving forward or backward.

Another mention, today it was upside angle, and this is the best it seems as my penis is downward curving, naturally the fibers are shorter in the ventral region, so these have to be extended, and the best way is to use an upward angle so the load is focused on these.

The control of peritendinous adhesions using topical β-aminopropionitrile base
https://www.sci encedirect.com/ … 022480485900344

β-aminopropionitrile free base topically applied reduces collagen crosslinking in healing wound, therefore flexor tendon requiring 50% less stress to flex.

Collagen inhibitor reduces the amount of stiffness, collagen strength, and thus required stress to obtain a certain strain.

Topical Beta-Aminopropionitrile in the Treatment of Peyronie’s Disease

Although no conclusive evidence was found to improve their condition, one patient saw improvements and less pain. Study was only 9 patients, but the safety of the compound is aparently safe topically applied.

Topical application of B-aminopropionitrile
https://www.sci encedirect.com/ … 024320581907116

The topical application of the free base version, aka ( I am not sure) non ionic aminopropionitrile, or 14C-BAPN free base (F.B.), all the same thing, is absorbed better through skin and into collagenous tissue. Less residue in urine than the fumerate counterpart.

All this leads me to one conclusion, although the second study mentions it may not have a significant effect on collagen already layed down, it does on collagen to be layed down. And it might have an effect on existing collagen if the dose is high enough.

Which means, that if we topically apply this we can weaken the collagen over time leading to longer strains, lower stiffness, and less strong collagen repair, allowing us to longterm attain longer elongation.

IIRC 30-50% improvement in the following areas: strain, stiffness, and required stress. Which would mean probably ~30% more gains if it works.

Now where can we get some? And it needs to be the free base version as it is less toxic apparently and more effective topically.

Also, I’ve been thinking about thermal cycling while cycle stretching.

“Thermal fatigue is a fatigue failure with macroscopic cracks resulting from cyclic thermal stresses and strains due to temperature changes, spatial temperature gradients, and high temperatures under constrained thermal deformation. Thermal fatigue may occur without mechanical loads. The constraints include external ones (e.g., bolting load) and internal ones (e.g., temperature gradient, different thermal expansion due to different materials connected). Compressive stresses are produced by the bolting load at high temperatures, or generated in the material having high coefficient of thermal expansion. Tensile stresses are produced when the component cools, or generated in the material having low coefficient of thermal expansion. Thermal stresses are produced by cyclic material expansion and contraction when temperature changes under geometric constraints. A crack may develop after many cycles of heating and cooling. The failure indicator or criterion of thermal fatigue is usually strain rather than stress. Thermal fatigue life is determined mainly by material ductility rather than material strength.”

“Anisothermal fatigue can sometimes be more damaging than isothermal fatigue. Isothermal fatigue occurs when tension or compression cycles are imposed at a constant temperature. Anisothermal fatigue occurs when the component temperature and strain vary simultaneously.”

How about cyclic stretching and heating/cooling at the same time to create anisothermal fatigue? Would have to cool instanly via an icebag of some sort. It could be worth a try….

No studies that I could find where they vary the rate of temperature change from high to low on tendon/collagen/ligament. But collagen is more ductile than it is brittle or strong.

I did the ice cool down before in the past but don’t remember getting any gains from it. I wasn’t heating as effectively as I do now though. I have been doing heating cycles with my last routine and got really good results. I did a routine like a my own hybrid of yours and kyrpa. I guess we’ve been reading the same threads. Coming back from almost a 2 year break probably had a lot to do with it.

The medication sounds interesting but I’d want more research before using it personally.

How are you doing these heating cycles?

I think for thermal fatigue to work the temperature changes and rate of change need to be quite drastic. Perhaps going from 40+ to less than 30. But it may not be easy so… at the end of the day it needs to be practical.

The medical compound has potential. I’m not sure how safe it is but it seems not harmful enough topically applied. I asked in the chemical PE thread if they know where to find it. As far as I know chemical PE guys ingest things that carry more risks and side effects.

Well maybe not heat cycles as you are interpreting it but the end of my last campaign I was doing 3 separate stretch sessions, all with heat the first 5 to 10 min then letting cool down last 10. This was 3 different sessions throughout day, started with one session and worked my way up. Also tried to do ADS before each stretch session with similar heat cycle; like 10 min in, for 10 min and 10 min cooldown. I didn’t measure pre BPEL like an idiot but was at least 1/4 inch gain and probably closer to 1/2 in a month’s time.
