FOCUS YOUR PE & GAIN! TGC Theory Explained!

[remek Founder Find all posts View Profile Close remek]

You might be exercising the wrong way and that could be why your not gaining.

That's the idea behind Tissue Growth Clues Theory, a theory created by Iguana and I.

Like nearly everything else in PE, all the information in this post is no more than a theory. This theory is different than most, though, as you can apply it and test it out right away; and you can use it to help you build a more "focused" routine.


Why so long?
Indeed, this is a long thread, but it might just be one of the most important threads you ever read. A good knowledge of the penis' smooth muscle and tunica (Part 1) is important for understanding the theory. That said, if you could care less about understanding the theory and just want to apply it or test it out, skip to Parts 2 and 3. Part 4 goes over the case studies and data we have for the theory.

PART 1: The Smooth Muscle & the Tunica

PART 1: The Smooth Muscle & the Tunica

Let's start with the tunica. The tunica is a strong tendon-like tissue that surrounds all three corpus chambers—and the smooth muscle within the chambers. The tunica governs the size of the erect penis similar to how a bicycle tire limits the expansion of the inner tube inside. As with a bike tire, once the limit of the tunica is reached, further pressure results in greater stiffness rather than expansion.

Research seems to indicate that, oddly enough, not every man has the same amount of layers of tunica. Most men have two layers, but some men only have one layer in their penis. Others have as much as three layers.

The Penis Smooth Muscle
Now, it's widely believed that the penis has no muscle in it. This is wrong. Your penis isn't a muscle, but it does have muscle in it. Think of it this way. You can enlarge your arms. Are your arms muscle? No way. Do they have muscle in them? Yes way (biceps, triceps, etc.). It's the same thing for your penis, only the type of muscle is different.

A healthy penis is made of roughly 50 percent smooth muscle.

What does the smooth muscle do?
The smooth muscle helps determine the size, shape, and hardness of your penis. Just as your biceps and triceps play a critical role in the size and strength of your arms, the smooth muscle in your penis plays a critical role in the strength and size of your erections.

Your erections are largely caused by complete relaxation of the smooth muscle in your penis. Here's how.

The erection process of a healthy penis, the smooth muscle view
Pre-Erection: Your penis is flaccid. Your smooth muscle, which is largely in the corpus chambers, is contracted. See Figure 1. In the figure, you'll see a cross section of the penis. Inside the three corpus chambers of the penis, you'll see several circular sponge-like spaces known as sinusoidal spaces. Inside these spaces is where the smooth muscle is. There are also some smooth muscle cells in your veins and arteries, but they are different from the ones in the corpus chambers.

The normal erection process:

1. Something turns you on.
2. The smooth muscle relaxes and blood flows into the penis.
3. When the smooth muscle is completely relaxed, it presses against the tunica and cuts off the veins that take blood out of your penis, as in figure 2.
4. An erection occurs

So, when a penis is flaccid, the smooth muscle is contracted. When the penis is erect, the smooth muscle is completely relaxed and pushing on the tunica.

AN IMPORTANT POINT: More Smooth Muscle = Harder Erections
Not all penises have the same amount of smooth muscle. Some penises have more than 50 percent smooth muscle; others have less than 30 percent. This difference is a major reason why some men can’t get an erection and other men can have an erection for hours on end. Says urologist Dr. Eric Wespes:

The amount of smooth muscle in the penis is the essential factor that determines a man’s ability to achieve normal erections.

And another study:

Sexology 2005: "It has been shown that decreased smooth muscle content is associated with an impaired erection."

Clearly, smooth muscle is important for strong, firm erections. The not-so-crazy part? The amount of smooth muscle in a man’s penis appears to decrease as he ages. In one study published in the International Journal of Impotence Research, Dr. Wespes measured the percent of smooth muscle in men of different ages. In his study, the men under forty had an average of 46 percent smooth muscle in their penis; men between forty-one and sixty had 40 percent; and men older than sixty had 35 percent. (Wespes)

An erection and the role of unhealthy smooth muscle in the penis:
It appears that when you don't have enough smooth muscle, or possibly when the smooth muscle is too "fatigued" to relax all the way, you aren't going to get a hard erection. Let's go over the two main problems that can occur with the smooth muscle during the erection process.

The problematic erection process:

1. Something turns you on.
2. The smooth muscle relaxes and blood flows into the penis. Possible Problem 1: The smooth muscle can't relax all the way. This might occur from many things, such as poor health. In terms of PE, however, it probably occurs if your penis smooth muscle is too tired from overtraining.
3. When the smooth muscle is completely relaxed, it presses against the tunica and cuts off the veins that take blood out of your penis. Possible Problem 2: The smooth muscle is completely relaxed, but the tunica is stretched beyond the smooth muscles "reach." This essentially creates a "gap" between the smooth muscle and the tunica, making it hard to shut off the veins.
4. If problem 1 or 2 occurs, a rock-hard erection won't occur. Problem 1 has already been dealt with by sparkyx in his PI thread. This theory tackles the possibility of problem 2.

Problem 2, further explanation:
At first glance, problem 2 may be hard to grasp, but it's very simple once you think about it. First, let's consider the smooth muscle and the tunica as two separate things we're enlarging, with two separate size "limits." For instance, let's do an example where the tunica "limit" is larger than the smooth muscle "limit." In this instance, let's say you're a 50 year old man who has never exercised his penis before with only 40 percent amount of smooth muscle (the average in Dr. Wespes study).

Your erections aren't as hard as they once were, as the smooth muscle is having a harder time reaching the tunica - in an essence there is a "gap". This has also caused your penis size to be a little smaller than it was when you were younger.

The good news is that the limit of your tunica has most likely stayed the same over the years, so the smooth muscle is what's holding you back. How is this good news? It appears that PE exercises the smooth muscle. This could possibly play a role in why a lot of men get quick, abundant "newbie" gains along with a quick increase in hardness. There smooth muscle was the limit, and PE enlarged the smooth muscle (or created more smooth muscle). In turn, the smooth muscle volume is sufficent enough to press all the way against the tunica, and the "gap" is eliminated.

A key point here is that you don't have to be a 50 year old man to have low amount of smooth muscle. We estimate that any man, at any age can have under-developed smooth muscle. For example, a man who doesn't obtain a lot of erections via sex and masturbation probably has poorly developed smooth muscle. It just so happens that men who are 18 tend to have a lot more erections than men who are 58.

Improper Training/PE Can Cause a "Gap"
It's been reported by several PEers who aren't overtraining and are gaining, that for some reason, they can never obtain "rock hard erections." In this case, the problem is probably that they are enlarging the tunica more than the smooth muscle.

How is this possible? We believe that, for the most part, when we PE we are dealing with two major distinct tissue types, connective tissue (the tunica) and smooth muscle. Given their differing structure and composition, the growth process for each tissue type is not the same; meaning a different training strategy is needed. Smooth muscle cells, unlike any other muscle type, retain the ability to increase not only in size but in cell numbers, while connective tissue does not have this ability. (More on how to enlarge each tissue in Part 2.)

The smooth muscle being the limit
On the other end of the spectrum, you can have the smooth muscle "limit" larger than the tunica "limit." In this case:

• The smooth muscle is at or approaching the maximum the tunica can hold.
• So the smooth muscle is bulging into the tunica (think of it as pumping up a 15" inner tube inside a 14" tire).
• This in turn causes the penis to be extremely firm and hard when you have an erection, or a "rock-solid" erection.

So, in an essence, if your goal is increased hardness, you'll want your smooth muscle limit to be above your tunica limit. But if you're looking for more gains, and your smooth muscle limit is above your tunica limit, you'll need to focus your PE efforts on your tunica.

PART 2: The Theory, Explained & Application

PART 2:The Theory, Explained & Application

The TGC Theory revolves around how you can exercise your "limiting factor," which is either the tunica or the smooth muscle.
The basis of the theory is that either the tunica or the smooth muscle is what's holding you back, and thus is the tissue you should focus your PE efforts on. We believe that the smooth muscle and the tunica are enlarged with very different exercises (the tunica is enlarged with mainly length-type exercises and the smooth muscle with girth-type exercises, although a few are interchangable.)

In this part, we will go over how we believe you can find out which tissue is your current limiting factor (we say current, as it can change in the future). In the next part, we'll go over how you can focus on that particular factor.

PE Isn't As Random As We Think
Any experienced PEer will tell you that you PE is variable and random - "you'll have to find what's best for you" is the common mantra.

It's true, PE can be very variable and random. However, the basis of this theory is that there are "clues" that penis gives off that aren't random - they mean something. And if they mean something, then we can interpret it's meaning to help us PE more efficiently and effectively. In a way, sparkyx already started tackling this idea with his PI theory. For this theory, you can use certain clues to find out what your limiting factor is.

Your Penis is Talking to You
Everything your penis does is a hint to how its reacting to the exercises. These "clues" offer insight on how you should PE. When we initially came up with this theory, Iguana, I and few other guys at The PE Gym talked about several different seemingly unexplained phenomenon that might not be so unexplainable, including:

• Why are some men growers and others showers?
• Why do some men get great expansion when clamping and other don't get any expansion?
• Why do most men report harder erections due to PE but some don't?
• Why is the BPFSL often so much bigger than the BPEL?
• Why do a few guys have a longer BPEL than BPFSL?
• Why do some guys get flaccid gains but not erect or the reverse?

After much debate and anecdotal research, we settled on two clues that we confidentially feel can help you know what is your limiting factor, the tunica or the smooth muscle, and thus the one you should target. These two clues are:

• Your BPFSL/BPEL ratio: That is, how much greater is your BPFSL than your BPEL?
• Your Erection Quality, or EQ: How hard are your erections on a scale of 1 to 10?

Clues the Tunica is the Limiting Factor
Main Clue 1: On a scale of 1 to 10, your erections are a 9 or a 10. Remember that the tunica surrounds the smooth muscle like a bicycle tire surrounds the inner tube inside. When you're erections are extremely hard, it essentially means that there isn't a large "gap" between the smooth muscle and the tunica. When your erections are rock-hard, as if the smooth muscle is trying to buldge out of the tunica - and as if a 15" inner tube was pumped all the way up inside a 14" tire - it means that the tunica is what's holding you back.

How is the tunica holding you back? We'll, if you enlarge the smooth muscle any more, the only thing that's going to happen is your penis is going to get harder and harder. Similar to how if you pump more air into an already-full inner tube, it's going to result in increased hardness not increased size. But if you increase the size of the outer part of the tire to 15", the tire will be ... 15".

Main Clue 2: Your BPFSL .5" or less than that of your BPEL. The tunica is most likely the part of the penis that determines how far the penis can be stretched (assuming all the tissues in your penis are relaxed enough for you to measure your maximum BPFSL). If the length of the stretched penis measures close the same as the erect penis, then that would suggest the tunica is at its limit when erect.

We picked .5" as the "magic number" because that's the number the data suggested. However, we're still in the beta stages here, so we may find that the magic number could be more along the lines of .25" or even .75". Either way, the closer your BPFSL is to your BPEL, the more likely your tunica is your limiting factor.

So, for example, if your BPFSL is 6.25 inches and your BPEL is 6 inches, then it falls within the .5" range and the tunica is your limiting factor. If your BPFSL is 6.6 inches and your BPEL is 6 inches, then it falls out of the .5" range and your smooth muscle is probably your limiting factor.

Clues the Smooth Muscle is the Limiting Factor
Main Clue 1: On a scale of 1 to 10, your erections are a 8 or less. Let's do a bicycle tire example again. But this time instead of having a 15" inner tube inside a 14" tire, you have a 13" inner tube inside a 14" tire. As a result, the tire isn't as big nor as hard as it can be.

This is essentially what happens if your smooth muscle is much less than what your tunica can hold. Your smooth muscle can't reach the tunica, and as a result there is a "gap." The gap essentially means your smooth muscle is holding you back and results in weaker erections. If you enlarge your smooth muscle, your erections should improve and your penis size should increase.

However, this clue alone isn't enough to show if the smooth muscle is the limiting factor. The reason being: Weak erections can be caused by numerous variables, such as an unhealthy lifestyle, a testosterone deficiency, and overtraining. You'll want to make sure that these other variables aren't the cause before deciding the smooth muscle is your limiting factor. Or, at the least, you'll want to check Main Clue # 2.

Main Clue 2: Your BPFSL is more than .5" greater than your BPEL. Remember that tunica is most likely the part of the penis that determines how far the penis can be stretched. So when the BPFSL is much greater than the BPEL, it means that the length of the penis can actually extend further than its length when erect. So your tunica length is already ahead of your erect length -- and thus not the limiting factor, making the smooth muscle the limit here.

So, in this case, when you get an erection, there isn't enough smooth muscle to completely fill the the gap between the tunica and the smooth muscle. But if you PE and enlarge the smooth muscle (or create more smooth muscle cells), then:

1. The gap will be filled
2. Your smooth muscle size will catch up the tunica
3. Your penis will get bigger and harder

WHAT TO DO RIGHT NOW: Find Your Limit!

1) Measure your BPFSL and your BPEL. Find out how much greater your BPFSL is than your BPEL. If it's around .5" or more, it indicates that the smooth muscle is your limit. If it's around .25" or less, it indicates that your tunica is probably your limit.

2) Rate your Erection Quality 1 to 10 using this scale.

10 - Raging rock-hard
09 - Very hard
08 - Hard
07 - Mostly Hard
06 - Somewhat Hard
05 - Semi Hard/ Semi Soft
04 - Somewhat Impotent
03 - Mostly Impotent
02 - Impotent
01 - Completely Impotent

Be very honest with yourself here. We've talked to guys who said their EQ was 8.5. Then we asked them to describe their erections to us and they were a clear 6.5 at best!

An erection quality of 10 is like that of a teenager: Rock-hard erections come consistently and easily (your entire penis fills up with blood and akin to being "made of steel"). Erections with the quality of a 9 also come easily, consistently, and are very hard - just not maximum hardness. If your erections fall in this range, it indicates that the tunica is probably your limit. If your erection quality is around an 7 or maybe an 8 or less, it indicates that the smooth muscle is probably your limit.

PART 3: How to Use the Clues Effectively

PART 3: How to Use the Clues Effectively

Once you know what your limit is, the fun part begins: Using your the clues to help you develop a more effective routine.

Using Your TGCs to Design Your Workout
In short, you can focus on exercising your smooth muscle by doing Ulis, squeezes, clamping, and other girth-type exercises where the pressure forms on the inside; and you can focus on your tunica with stretches, hanging, and other length-type exercises.

Now, you may ask: Why should I focus on just one tissue, why can't I do both length and girth exercises? The answer is that you can, if your TGCs don't clearly show that either is your limit. If, however, your TGCs show that either the smooth muscle or the tunica is the limit, you'll want to exercise the limit. If you don't, gains will probably be hard to make and possibly won't happen at all.

Exercising your smooth muscle when your tunica is the limit doesn't work because it results in hardness instead of size! It's like putting more air into a tire that has already reached its maximum capacity. This is great from a penis health perspective, bad from a penis enlargement perspective.

Exercising your tunica when your smooth muscle is the limit doesn't work because the more the tunica enlarges without the smooth muscle enlarging, the more your erection quality will suffer!

How to Exercise the Tunica
We believe that length-type exercises, where the pressure generally forms on the outside, focuses on the tunica more. This doesn't mean stretching and length exercises doesn't exercise the smooth muscle. In fact, the opposite is probably true: When we are stretching, hanging, or using an ADS, we are stretching both the smooth muscle and the tunica. However, it would appear that the tunica is probably taking the blunt of the stress, as it is the tissues closest to the point of origin. In other words, the tunica is on the outer layers of the penis, the smooth muscle is on the inner layers, and stretching is generated closer towards the outer layers. Meaning, if you are hanging, the hanger is on the outside of the penis, pulling the tunica.

If your main focus is to get more girth, yet your tunica is your limit, it's probably possible you can focus on the tunica with certain exercises like the Flaccid Bend and HammerHeads (compression squeezes.)

How to Exercise the Smooth Muscle
Girth-type exercises like squeezing, clamping, and Ulis also workout both the smooth muscle and the tunica However, it would appear that when we do girth exercises, the main pressure comes on the inside (from a rapid influx of blood flow). This directly causes your smooth muscle to expand, which indirectly causes the tunica to expand (when the smooth muscle presses against the tunica). Thus, the smooth muscle is probably taking the blunt of the stress as it is the tissue closest to the point of origin.

WHAT TO DO RIGHT NOW: Focus Your Routine
A key point here: You don't have to completely change up the days you do your routine, how often you do it, etc. - just make sure the exercises you're doing focus on the tissue that is the limit.

If your smooth muscle is your limit: Adjust your routine so it is mostly girth-based. That said, you don't want to focus completely on girth. You should do at least 10% to 20% of length exercises as well, and possibly more, as length exercises do most likely stretch the smooth muscle to some degree and help it to expand. If your goal is length and girth, you'll probably want to make your routine roughly 30% length-based and 70% girth-based. If your goal is only length, you'll still want to do at least 60% of girth exercises and possibly more. Also focus your jelqs with a high erection level, around 70% to 90%.

If your tunica is your limit: Adjust your routine so it is mostly length-based. Again, you should still do at least 10% to 20% of girth exercises as well, and possibly more. If your goal is length and girth, you'll probably want to make your routine roughly 30% girth-based and 70% length-based. If your goal is only girth, you'll still want to do at least 60% of length exercises and possibly more. Also focus your jelqs with a low erection level, around 40% to 60%.

Part 4: Case Studies

PART 4: Case Studies

No doubt this is not the first PE theory you have encountered in your career and it probably won't be the last. The problem with PE theories is they most often just remain that - theories. Most are debated endlessly only to die a slow death and very few ever enter any kind of application phase. This is where we hope this one will be different.

We reason that if this theory is correct, real world application will bear that out. If not, then it's sure to earn a spot in the the acclaimed PE theory graveyard. Even if the theory turns out to be incorrect, we hope that it persuades people to start thinking about the clues the penis might give off, and possibly this thinking will lead to future discoveries.

So to test a portion of the theory, we conducted a survey on this site as well as several others. We asked guys to contribute their BPFSL & BPEL measurements, as well as EQ (erection quality) on a scale of 1 to 10. The assumption was, if the BPFSL measurement (a good indicator of tunica length)was significantly greater (over 1/2") than the BPEL measurement, erection quality would suffer.

We currently only have around 80 participants. Given the memberships of all the sites surveyed is well over 100,000 we were hoping for a better response. At this time we still have results trickling in and have decided to keep the poll up for a little longer to see if the posting of the theory generates more support. As of this writing, 60 to 90 percent of the results you guys posted support this theory (depending on the which way you look at it). We thank all the guys who took part in the survey. After more data is posted in this thread, we'll post a detail explanation of the results.

Case Studies
In addition to the data collection, we looked at a few cases, in addition to our own, for real world application. Would this theory work when put to the test? Better yet, were others unknowingly applying this strategy and getting good result? In other words, how many vets had gained from training this way and were totally unaware of the significance?

Timesbechangin - Tunica Case
Times had very hard, consistent erections (an EQ of 9.5 on a scale of 1 to 10). His BPFSL was roughly .15" longer than his BPEL at it's absolute maximum point. He had been at a plateau for several months. His routines we're mostly girth-focused, which using TGC theory suggested to that the reason he wasn't gaining was that he was focusing on the wrong tissue. He was advised to switch it up and focus on his tunica with length exercises. After roughly two months of focusing on the tunica, he's gained nearly .5" in length and .15" in girth. His EQ has decreased to roughly 8.5 and his BPFSL is now over .25" greater than his BPEL.

Iguana - SM Case
Iguana was suffering from poor EQ (around 7) for several months and gains had slowed to almost nothing. He elected to take a 3 month decon break thinking his EQ would improve. After 3 months he lost 1/4" EL and his EQ had not improved. He had a BPFSL/BPEL difference of 1/2". After realizing his routine was very tunica oriented (lots of stretching/extender use) he switched his routine. The results? After two and a half months of a smooth muscle based routine his BPFSL/BPEL difference had dropped to 1/4", he regained the 1/4" loss and added another 1/8" El and his EQ was at 10.

remek - Tunica Case
Prior to TGC theory, remek's erections were a solid 10. He would consistently maintain an erection after he came. His BPFSL was exactly the same as his BPEL (and in some cases shorter if he didn't warm up prior to measuring his BPFSL). His latest routine was girth-focused, which improved his EQ even more but not his gains. When he realized that his tunica was his limit, he switched to length-focused exercises and gained .2" in length and a little bit of girth in roughly two weeks. His BPFSL increased slightly further than his BPEL and his EQ dropped to a 9/9.5.


Hope this theory helps!

Great read and very informative. Thanks a lot. I believe my smooth muscle is the limiting factor as my bpsfl is 1.0'' more than my bpel, so I will focus more on those exercises over the course of the next few months and I will let you know how it goes. Props.

Interesting theory guys.

I'll add my stats into the pot as well.

BPFSL: 7.625"
BPEL: 7.00"
EQ: 7

I regards to erection quality there are many variable which can affect hardness, frequency and duration. I can have nocturnal erections of a 10 rating. The kind that will wake me from sleep but I do not get these every night nor do I wake with "morning wood" every day.

I am just recently (within the last 5 days) getting back into PE after a break of about one year.

[phallic1 Senior Member Find all posts View Profile Close phallic1]

Pondering penis's while reading over the TGC theory and Shane Diesel, John Holmes and Shorty Mac came to mind. These guy's all have huge penis's in length and girth but none seem to be able to achieve an erection much over 75%. Although we do not no their BPFSL or BPEL measurments could we assume based on TGC theory that smooth muscle could be the limiting factor in erection level? Yet, Diesel, Holmes and Shorty Mac's penis's appear not to be lacking in internal corpus cavernosa or spongiosum development. By that I mean their penis's look engorged and very full, appearance of "ribs" and well developed vascularity.

Are appearance decieving??

Hey igauna are you any relation to Godzilla?

im implementing the theory in my own progress thread over at Thunders "Discipline pays off." I started Saturday.

[wohoo19m Junior Member Find all posts View Profile Close wohoo19m]

Wow, that was a VERY interesting read. I've lacked gains for a while now, and I have pretty much a 9.5 - 10 on the scale. I'd been considering if adding length exercises was the missing factor to my routine. But I'm definitely doing to be a guinea pig for your theory. I've been doing girth work mostly for the past year and not seeing much results. Only results I had was when I was doing piss sessions where I gained 1/8" in a month. But I stopped afterwards because the skin under the glands was getting too irritated...Time to focus my efforts somewhere else.

Well done guys
