Girth and length simultaneously
I know there are people jumping all over the internet and shouting it should not be done but never mind.
Many have done it before and many will in the future.
I like to think my cock expanding in volume and filling up some fortunate women instead of only lengthening it to be shown in internet.

After some weeks of kegeling against external force I am seeing similar results to you in terms of EQ.

I also find that I will now only stretch when there is an IC/PC contraction to pull against. Stretching completely relaxed feels damaging while stretching while contacting feels productive. Are you still doing relaxed stretches or are all stretches for you now supported by your IC muscles?

I agree about length and girth at the same time. For me any gains I have seen tend to be both length and girth at the same time. I don’t know how to isolate one without the other and believe that the penis will tend to grow in a particular proportion whatever we try to do with it.

Wantmoregirth,

At this moment I am still recovering from blister on the glans. So the use of vacuum attachment is out of the question for a while. Now after a week of healing I am able to work with manual stretches, jelqing and exercising cavernous muscles.

But as a principle, yes I do relaxed stretches when working with TA. When training these muscles I do not allow fully relaxed state during the set. And I perform TA and muscle targeting exercises separately .

To get full potential in penis volume expansion one needs IMO:
- To expand or lengthen tunica. As a collagen structure it is best done by stretching it in a fully relaxed mode. Stress relaxation being the key.
- To perform exercises which induce growth. This is where training penile skeletal muscles and cyclic stretching of cavernous smooth-muscle comes to a picture.

And with the training by the feel you are right. Stretching the tunica effectively enough may feel damaging and it affects IC and BC muscles exhausting them and lowering EQ within. I personally go to a discomfort levels with stretching the tunica.

Training cavernous muscles and stretching penis against muscular contraction really feels productive as you described. It really feels good and results are seen very soon in a form of better functioning unit , better flaccid hung and healthier overall feel on penis. This is by the way a very straightforward analogy from fitness/ bodybuilding world.
If I were on comfort zone with my size already I surely would stick with this method only.
If chasing girth only this and carefully picked girth exercises could be all needed.

Hopefully at some point I can reach BPFSL long enough to start only filling the space so to speak.
But as I really don´t think I can grow my unit to meet my goals with a tunica this size, I should keep on molding it further.

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)

You say it is best to stretch the tunica in a fully relaxed state. Can you voluntarily relax or contract the tunica? If so, surely that has no bearing on whether you are contracting your IC to support the base?

It is obvious that no one can voluntarily contract or relax their tunica.
Indirectly so as ligamentous stress relaxation is mostly time depended phenomenon when using constant load to achieving it. To ensure this I prefer to be in relaxed mode as one need to be stretching any ligamentous part of their body.
I am not saying you are doing something wrong. I am a student of this PE thing myself and stating things I am personally running to make some progress. Actually I see a point as well on what you are saying.

What I am saying is to get the maximal elastic lengthtening I suppose it could be beneficial not resisting the process by contracting supporting skeletal muscles. The whole thing about collagen based tunica is that if only stretching at elastic level the lengthening achieved would not be permanent.
In my case having very resistant dorsal thickening even elastic lengthening without excessive amount of heat is not achieved.

Once the ligamentous stress relaxation of TA is achieved then your method could be considered as a tool to target stretching efforts to TA. Or maybe what you are doing is just the heavy duty bodybuilding exercise for cavernosum muscles using these ultra heavy loads for stressing them?

I am interested with your method as tool for targeting fulcrum stretches on different parts of the tunica. I will try it for sure. Are you making measurable results?

7th month Healthy again

Monthly update on progress, which is measurable
BPEL 19.9cm ->20.2 +0.3cm
BPSFL 21.3cm->21.4 +0.1cm
MSEG* 14.6cm->14.7 +0.1cm
*Documented mseg is average from base (15.6), midshaft (14.6) and behind the glans girth (13.9) for more accurate volume calculation.
Measurements are taken being two days off from PE activity.

After getting injured I took a week off as my unit was too sore and tender to do anything with it.
During week two after the injury I started gently with jelqing, AM2/3 , manual cyclic fulcrum stretches and IC / BC muscle training. During the week three I was able to perform manual stretching and first experiments with vacuum stretching. While recovering some girth was lost at the most acute phase but it came back quickly when started to feel and looking healed.

Before the injury I had difficulties to make progress with BPFSL keeping same measurements day after day. Unit felt increasingly resistant to be stretched despite the heating efforts and time put on it.
I was positively surprised how easy tunica stretched after being almost three weeks off stretching, pumping and clamping. Measured post workout BPFSL 21.8cm without any heat used.
As the situation evolved in positive manner I am not going for de-conditioning break or macro P-phase with ADS yet. I am going for more BPFSL.
Now the tunica feeling mold-able again I will recycle routines which have given me best lengthening on BPFSL.
I`ll try to emulate my 4th and 5th month routines as closely I could. Great thing is I have documented it quite precisely so it would be easy follow.

Of course there will be minor tweaks here and there but the main core would not be altered.
I have been taking one week off for every four or five weeks to date. Now after experiencing this healing process after a big blister I will introduce 2 weeks off every four to five weeks now on.
I feel motivated and enthusiastic and will be posting weekly this following month or so as I am curious to see what will happen.

Week 35 update

BPFSL gains from a manual stretching. As mentioned before I felt that gains can be achieved again after a few weeks of plateauing.

BPFSL 21.4m-> 21.7 +0.3cm

2nd of march I kick started this month with a 5min AM 3 practice and 20min jelqing session in the morning followed by 2 hours vac stretching session later on the same day. Following day I had family time so no thoughts on PE at all.

First serious attempt to hit the tunica was day later as I used vac attachment with a elastic band to stretch the unit.
Using it altogether 4 hours during the day pulling downward towards the knees and upwards pointing to my hips with a ~1 kg load. Didn’t take any measurements.

Following day I performed stretching session with stress relaxation method. With same approach as earlier I gradually upped the load within an hour to reach the elastic lenghtening of the tunica and ligs.
This was followed with a manual stretching session of 20 mins pulling in every direction in 30 sec cycles.
Measured before any activity BPFSL 21.3cm. After manual stretches BPFSL 21.8cm. Strain 2.3%.

Day later was the main exercise of the routine with ultrasound heating.
After elastic limits was approached with same method as day earlier, 20 min heated stretches were pulled with ~2 kg load. 10min towards each hip. This was followed with a 20min manuals not using US anymore.
Measured before any activity BPFSL 21.4cm. After manual stretches new record BPFSL 22.0cm. Strain 2.8%.

Third continuous day was with ADS use for 4+2 hours with a homemade ADS loaded with ~0.8 - 1 kg.
Measured pre BPFSL 21.5cm and post BPFSL 21.9cm. Strain of 1.9%.

Days four and five just resting with some AM3 on day 4 and measured increased BPFSL of 21.7cm each day.

Week 36 report

8 inches BPEL

BPSFL 21.7cm-> 22.0cm +0.3cm
BPEL 20.2cm ->> 20.4cm +0.2cm

Two out of three short term goals achieved as I managed to get in to a eight inchers division.
Not that my world is any better now but it makes me happy and confirms that anything is possible when you are willing to bring the efforts needed.
I am convinced on eventually reaching my goals.

Started on Sunday with 20min jelqing and AM3 session.
On Monday 4 hours wearing ADS on three separate rounds. One of the 1 hour sessions was followed with 20min manual stretching. Later on prior to sleep 10 mins of jelqing.
Measured pre BPFSL 21.7cm and post BPFSL 22.1cm. Strain of 1.8%.

Tuesday as monday with AM3 first thing in the morning.
Measured pre BPFSL 21.7cm and post BPFSL 22.2cm. Strain of 2.3%.

Wednesday was the main day. 5 mins AM in the morning.
Due to limited time only 30min pre stretching before 20mins US heated stretch. Heated part as in previous cycle. This was followed with 20min manual stretches. 20min post stretch as a cool down. Before bed 10minutes jelqing.
Measured pre BPFSL 21.6cm and post BPFSL 22.0cm. Strain of 1.9%.

Then there is three days off with a two days long sex marathon. Measured 22cm BPFSL and 20.4cm BPEL both thursday and Friday.


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"

Week 37 report

Lenght gains in process

BPSFL 22.0cm-> 22.2cm +0.2cm
BPEL fluctuates between 20.3 to a whopping 20.6 cm but I won’t rush to claim anything yet.
Hopefully with a one more week and confirming measures I can claim the 20.6cm which means full 1 inch gain in BPEL.

Spend three days of from PE. First resting day my EQ was poor as my unit was not fully recovered from exercising but following days all started to be as good as it can be. I can see my IC and BC muscle training are now benefiting on sexual performance.
Great weekend with my first ever threesome with two horny girls.

Not mentioned lately in PE routines but I do additional exercises to mainly IC muscles few times a week. Due to this my erections are better than ever and my EQ level is very good in any means.
I do regular kegeling as well but honestly speaking can not say do I really need to practice it to a top of much more efficient method.

Long story short as I only state the exercise results.
Day 1
Measured pre BPFSL 21.7cm and post BPFSL 22.3cm. Strain of 2.8%.
Day 2 rest
Day 3
Measured pre BPFSL 22.0cm and post BPFSL 22.6cm. Strain of 2.7%.
Day 4
Measured pre BPFSL 22.0cm and post BPFSL 22.6cm. Strain of 2.7%.
Day 5
Measured pre BPFSL 22.0cm and post BPFSL 22.8cm. Strain of 3.6%.

Day 5 is the best strain percentage I have documented. Difference in this workout was the fulcrum stretching part in manual stretching routine.
I usually divide manual stretching to a 15mins with axial stretches in every direction and 5 mins to a manual fulcrums. This time I made it to a 10 plus 10 minutes. Have to mention that this time it felt the present strain limits were reached as stretching 30 secs at time felt very discomforting.
Manual fulcrums are performed using my free hand as a fulcrum to a almost every imaginable direction from several pivot points along the shaft.

Fantastic log and progress Kyrpa. Congratulations on both 20 cm and 8” BPEL milestones recently.

Are you still using the ultrasound during vac stretching? Could you link to the type of machine you use?

Thank you BD. Really appreciate your comments as I have been reading your posts with a lot of attention.

Yes I do use it regular basis. In fact this weeks days four and five were exercised under US heat. I am not using it in every session.
Now when I am having a good flow with the results I use it when it matters the most. I try to be progressively performing each session of every cycle.
As the gains start to slow down I use it in every stretching session.

Ultrasound which I am using is US Pro 2000 2nd Edition

I have already mentioned here in this log and elsewhere also that this unit is only just about powerful enough and I sincerely advice to get more powerful one if possible.

There have been discussions of about it for example from page 40 forwards in here:
Knowing whether you are limited by Dorsal Thickening/Septum (p. 40)

Manko007 has done a great work on documenting his US use. I recommend to look in his posts.

Thanks Kyrpa. The last two days I have read all over the forums about ultrasound’s use for heat in PE. You guys are breaking new ground here. The idea has been batted around for years but seems you two are the first to run with it, and with good initial results.

Manko’s urethral temperature testing shows that the ultrasound can reach up to 43-45 Celsius, while the IR lamp can only get 39-40 Celsius. However, this takes constant application of the ultrasound transducer, whereas the IR lamp heating is completely passive. At a suggestion from firegoat in another thread - if the same activity level were used with an IR lamp, by using the hands to apply and re-apply various microwavable heat gel packs or heated rice sock - then perhaps the “active IR” heat level could approach the same heat as ultrasound.

One also must wonder if the micro-vibrations (cavitation) from the ultrasound is assisting your quick gains. I assume this energy would also contribute to the melting of collagen bonds.

Equally important to the ultrasound is the way you both are using BPFSL pre- during- and post- workout strain metrics to monitor the effectiveness of your methods. Your gains are assured by doing this, and it has confirmed for me that targeting BPFSL is a reliable source of gains. Personally I have been stuck in PE for 2 years since switching from a length focus to a girth focus. Now I believe I must target BPFSL and length again in order to gain girth via the Poisson effect.

On the whole, I am reluctant to spend 700 USD for the 3 Mhz unit despite your good results. I watch your progress with interest.

Well what can I say, Thundersplace is full of theories and hypothesis yet to be fulfilled from some great kitchen scientists present and past. Applications been lacking.

Generally speaking a decade ago there have been some great debates over causes of PE induced growth and how the growth occurs. Guess they all eventually fade due lack of hard medical evidence from PE applications. Lot of misleading information too if one is not aware enough to filter it properly.
But there is evidence enough from studies how to stretch ligaments and tendons. Same goes for anecdotal knowledge from fellow PE enthusiasts adapting this information to PE applications.
One of the usable tools is ultrasound other being ligament stress relaxation which are both covered in this application here.

Based on my tryouts I am convinced that you need to be at minimum of 40-42 Celsius.
Unit I am using is not effective enough to maintain these temperatures without external heat pad of some form. And as you mentioned it has still to be continuously used during workouts. Clear advantage to ultrasound is that there is simply no fear of skin burns with it.

Cavitation could be a factor here but the temperatures themselves I am running are probably not high enough to melt collagen bonds. US is thou an active tool in a form of collagen orientation.
Collagen fibrils tend to align with the direction of the force when tissue being stretched.
This orientation is highly accelerated with low intensity ultrasound. I interpret this as a rapid BPFSL gains.
This is also the reason I will not introduce ultrasound to a unstretched penis.

Honestly speaking I find it difficult to accept majority of PE practitioners ignoring the value of BPFSL gains. This should be the main concern for every stretcher and hanger at least. BPFSL comes first then there is a great chance for BPEL or even girth gains to form if the practitioner is capable to produce them.

You have summed it up nicely concerning most of the main components here.
One thing I would like to additionally emphasize is the ligament stress relaxation being in important role in this approach.
Your reasoning sounds solid about the Poisson effect. This way I like to explain my simultaneous length and girth gains. In fact after fast BPFSL gains I introduce girth orientated workouts to fill the void so to speak. And so far it has worked quite well gaining rather proportionally.

PS. I am still running with a 150 USD apparatus knowing it might be easier with a better one.

Ultrasound is sounding better and better.

Years ago I attempted to build the "robocock" stress relaxation extender as marinera called it, from this thread:
My Stress Relaxation-based Traction Device in Action

However, the base was too uncomfortable and I did not pursue it much longer. I was interested in using it in a hot bathtub - now I wish I had stayed with it. Many big gainers tell of doing their routine in hot tubs, which are 40 degrees.

Anyway I am now very tempted to dust off this equipment and use the adjustable wingnut attachment, upside down U, attached to a rope or bunji as a stress relaxation hanger with ultrasound.

Would using the ultrasound next to this metal interfere at all or overheat the metal? There would be no room for the transducer on the sides, I think. Perhaps some modifications are necessary.

How do you rig the vac hanger for your stress relaxation?

That Robocock equipment would work perfectly.

I have really simple mod in my penimaster. It locks out when original adjustment bottoms out. So I put the thing on at near top range and after 5 minutes adjust it to max and lockout.
Every 5 minutes adjust more an leave it there and so on. My modified phase two springs at the top end won’t interfere as they kick in at higher compression.

When using elastic band as a stretcher I attach the band just below the knee with a load of maximum 1kg. Then lock the vacuum attacment head against my thigh with strap.
Every few minutes adjust some more pull and so on. 30 minutes is the minimum when using these fixed lenghts but I tend to stay longer.

Same results are achieved with constant load as I have find out but it takes much more time.
It would take near to two hours to get the maximum elastic lenghtening aka stress relaxation. Load should be increased in increments.
This weeks workouts for example have been done this way with a constant load for stress relaxation before heated vac stretching and manual stretches.
I´ll put some report out later on this week.
These manoeuvres are only done to prepare penis to be ready for actual workouts.

US is easily operated between metallic bars. It doesn’t matter if the transducer touches rods as no problems have occurred.
Sound waves are reflected from metals anyway so the rods will not get heated.
