So you've finally heard about the results that penis extenders can provide, huh?

Most men like to keep these secret weapons to themselves since they're not mainstream.

In this guide, I'm going to tell you everything you need to know to buy a penis extender, so that you don't get ripped off.

Or if you want to go straight into the PhalloGauge Extender, go here.

What is a Penis Extender?

Penis extenders (not to be confused with the sex toy, penis extensions, a.k.a penis extender sleeves), are also known as penile traction devices and penis stretchers.

Comparing what a penis extender looks like to a penis extension.
Here, we talk about penis extenders, medical devices used to increase length permanently, not penis extensions which are sex toys.

They are simple machines that were invented to hold the penis in the penis traction position to trigger hyperplasia and result in penis length gains.

They have existed for about 20 years now and are still used to this day because of the 100% real results that you guys gain from them.

Why are they so popular?

Well even the family-friendly WebMD acknowledges that the function of penis extenders work.

"You might have to wear a weight (or penis extender) strapped to your penis eight hours a day for six months," says O'Leary. At the end of it, you could be lucky enough to gain about half an inch." --WebMD

(Even WebMD recognizes that it's possible.)

How Do Penis Extenders Work??

Penis extenders work by utilizing the traction principle.

The traction principle invovles keeping a body part in a "stretched" position for long periods of time.

As a result, the body gets used to the stretched position and triggers "cell hyperplasia" to adapt to the environement.

Cell hyperplasia means that the cells in the body tissue (in the case the penis), split and duplicate, increasing the total amount of penis tissue cells.

The end result is indisputable, permanent size gains due to increased penis tissue mass.

The traction force causes penis cells to divide - resulting in a net increase in penis tissue mass = physical size increase.

As you can see, tissue growth through cell division is a perfectly ordinary process.

So ordinary that it happens in every human male's penis when they're developing before birth, as well as during puberty.

But what happens after puberty?

In terms of natural growth - you're out of luck.

You need a form of stimulus to trigger cell division growth.

In the case of birth and puberty, that trigger was a combination of hormones.

But for post-puberty? The necessary trigger is "traction".

And the only way to get "traction" is with a penis extender.

Penis Extender Types

Rod-based extenders

The old style of penis extender devices typically consisted of a rod, noose, and spring system.

Certain rods and springs are installed when you want to change the amount of force that you want to apply to your penis.

When you placing your penis inside of device you slip the base of your glans underneath the noose and you tighten it to clamp it down and hold it in the stretched traction position.

Pulling extenders

Pulling extenders use the instinctual nature of pulling to create the traction force.

Typically, there is a part that grips the top of the penis shaft, and a belt that comes around that anchors to the base of the penis.

A critical part in the pulling penis extender type.

The advantage of pulling penis extenders over rod-based ones is that they can be worn underneath any kind of pants without being detected.

Rod-based extenders hold the penis straight out which risk large bulges in pants.

Penis Extender Buying Guide

Here we put the prices of the extenders currently on the market.

However, because there are generally different packages that you can buy with these extenders, the price varies and might actually be a bit higher.

Brand Type Typical Price Notes
PHALLOGAUGE Pulling $95 Pulling extender with elastic belt and silicone grip.
SizeGenetics Rod & Spring $250 A standard, plain rod penis extender.
X4 Labs Rod & Spring $200 Rod-based extender with various accessories.
Phallosan Pulling $339 The most expensive penis extender on the market.
PeniMaster Pro Hybrid $325 Optional vacuum system with rod and frame.
Male Edge Rod & Spring $180 A second iteration of the Jes Extender
SizeDoctor Hybrid $350 A Korean penis extender similar to the PeniMaster
Jes Extender Rod & Spring $200 Original rod-based extender, replaced by Male Edge extender.

What is typical extender device usage like on a daily basis?

Once you get your penis strapped into the penis stretcher, there's a couple options that you can go from there.

Some penis extender devices have the option to angle your penis pointing upward or downward.

When you decide what direction you want your shaft pointed in, you can proceed to put your underwear or pants on and go about your day.

While some devices are still inhibiting in that they can't be used in public, they still allow you to have access to the use of your hands so that you can operate a computer or do cooking.

You do have some mobility in that you can walk around but you have to be careful to limit your movement so that it doesn't slip off.

Most guys that try to use the devices at work generally visit the bathroom and use the bathroom stalls to monitor and maintain the device.

After all, this is the only practical source of privacy unless you have your own private office.

You pretty much have to think about your personal situation and where you can put it on and take it off privately.

We mentioned the public bathroom at the office but other places that come to mind could be inside your car or in a closet some sort.

How to Use a Penis Extender

How to put on a pulling stretching system

  1. Make sure your penis is flaccid (ideally under 20% hardness)

  2. Fit the soft foam loop base against your pelvis, around the base of your penis.

  3. Secure the top of your shaft in the gripping mechanism.

  4. Hook the gripping mechanism to the pulling belt.

How to put on a rod based extender system

  1. Make sure your penis is flaccid (ideally under 20% hardness)

  2. Fit the hard base against your pelvis, at the base of your penis.

  3. Gripping your glans, fit it into the opposite end.

  4. While holding your glans there, tighten the noose so that it clamps onto the upper shaft.

Penis Extender Results

The generally accepted results for stretching systems are as follows:

.7 inch length gain in 16 weeks.

That's quite a remarkable result given that even the thought of trying to increase your penis size was thought to be a waste of time.

I don't know about you, but if I found out that I could permanently increase my penis size by nearly an inch with practically no safety risk, I would go for it 100%.

But don't take our word for it.

Here are the the clinical studies done that contain all the data that back up these results.

The original sources to each of these article summaries on the studies are linked to in the article.

Penis Extender Routine

How long should I use the penis extender each day?

That's a great and important question.

The typical recommended usage for each day is about 3 to 6 hours, with 4 hours as a more specific recommendation.

Ane example of an all-day stretching routine: Start at 9am, Stop at 3pm.
A solid routine is from 9am to 3pm with a 20 minute break at lunch (12pm).

If you're a complete beginner you definitely don't want to train yourself too hard and risk stunting your growth from overstretching.

Thus, we would highly recommend that beginners just get used to the device for the first couple weeks and only stretch maybe two to three hours a day.

Because of the high hour requirement that is required by wearing enlargement devices, you have to plan your day around its usage.

See, the reason why you have to stretch for so many hours a day as compared to a 20 minute manual stretching exercise session is because when you use the penis extender device, you want to keep the average force lower compared to the force applied during manuual stretching.

In order to compensate for this lower applied force, you make up for it by simply stretching for a longer amount of time during the day.

This formula has been proven and there are clinical results backing it up.

Penis extenders also need to be cleaned periodically and can be done by using water and hand soap.

Running water and soap over a penis extender to clean it.
You should clean your penis extender at least once every two weeks.

You really need to do this in order to remove body oils and dead skin cells off the device.

Cleaning them in this manner is really straightforward and is not difficult at all.

A Step-by-Step Daily Extender Routine

This is the most reliable, and easiest routine that you can follow, based on personal experimentation by our whole team here at PhalloGauge.

It guarantees you get the necessary hours of stretching in during day and minimizes the device maintainence overhead.

  1. Put on the extender as part of your morning routine (like after brushing your teeth). Make sure to use the bathroom before putting the device on.

  2. Commute to work or your daily tasks. Wear the device until lunch.

  3. Lunch break. Go to the bathroom and take off the device before you eat and keep it off while you eat. Feel free to relieve yourself at this point as well.

  4. Lunch break over. Go to the bathroom and put the device back on.

  5. Commute home. (The device is on until you finish work!)

  6. At home. Take off the device and relax! You're done with the routine. You don't have to worry about it for the rest of the day!

  7. Bonus step: Clean the device. Doesn't have to be done everyday just once every two weeks or so.

For more details on the routine above. See this.

The good thing about this routine is that you don't have to worry and count the hours stretched.

That's because it was designed to revolve around your schedule.

This routine is typically for a regular weekday workday, but can be followed for weekends as well.

In fact, it's even easier to do on weekends!

How much do penis extenders cost?

Unfortunately, penis stretchers are pretty expensive.

They typically cost you more than $150.

Some even go as high as $339!

Showing the price tag of the PhalloSan penis extender.
At $339 (not including shipping) the PhalloSan is one of the most expensive penis extenders are the market.

Unfortunately, there are essentially the same device with no significant innovation or improvement over the past 20 years.

That is, they all consist of the same rod, noose and spring system.

While there are some slight differences from extender device to extender device, they are few and far in between.

So ultimately, it doesn't matter which penis extender device you use, because all that matters is it's ability to hold your penis in a light, stretched position for long periods of time.

However, if you're looking for the cheapest extender, you may want to read up on the different consequences of doing so.

What is the Best Penis Extender?

Answer: The PhalloGauge Model S penis extender.

However, the Model S Extender Traction system that we sell here at is one that has addressed users' issues with all the rod-based systems.

While the rod-based systems are a pretty good first attempt, and while they do have some non-zero value, there were definitely improvements that we made to it to guarantee that you can achieve success.

Some of these points are as follows:

The extender device needs to be completely invisible so that it can be used in public.

This is absolutely necessary because given the requirement that the product needs to be worn for long periods of time (ideally 6 hours a day), the usage of the penis extender should revolve around your life not the other way around.

Another issue is the fact that so many parts are used and the rod-based system is really complicated.

This is because the Model S consists of only two main parts of that take less than 30 seconds to put on and take off combined.

Another problem with extenders is that they are notorious for slipping off, especially at the worst times.

The Model S address this issue by using a flexible, stretchy silicone polymer wrap that completely melds and grips the base of your penis glans for a fantastic grip without squeezing the hell out of your penis.

What to Expect From Wearing Penis Extenders

Now that you know how to put on the penis traction device, what can you expect when wearing it?

After all, you're going to have to wear these things for hours each day.

How does the base part feel against your pelvis?

For all extenders, they have a base part that goes against your penis.

base part of extender
Typical example of foam loops for penis extenders.

This part can be a foam loop (as shown above) or a rigid frame.

Because it is one of the parts that is making contact with your body, you can expect that there will be some force applied to your skin at that point of contact (Newton's Third Law).

Newtons third law as it applies to penis extenders.
How force is generated by penis extenders.

Because the penis extender is applying a stretching force, it needs to stabilize itself at this base part.

For some guys, this will be slightly annoying or irritating.

Some guys will be more sensitive to the force applied to the base of the penis shaft, compared to others. However what we find with most guys is that as they use the extender device more often, they will adjust and eventually won't be affected by the force applied to the base part.

Generally, when you apply a higher force, the force applied to the base of your penis will also be higher.

So here's what we recommend: If you're a penis enlargement newbie, you should probably not even focus on stretching for the first two days.

Take these two days to get used to wearing the device. You can do this by simply applying a very low force that gives a very light stretch.

Next, slowly try to increase the tension in the device to the point where you can wear it for the recommended four hours a day.

The actual stretching sensation that is felt in your penis shaft

Imagine doing a light leg stretch with your leg.

Now try to translate that sensation in your tendon, but 100 times less in intensity to your penis shaft - that's what it feels like.

It's not painful, in fact, some have even reported that it feels good.

The warm-up mentality also applies to penis enlargement!

Generally, you won't experience any problems with the actual stretching of your penis.

This is pretty ironic because you would think any pain experience would be on the part of the penis that is experiencing the majority of the force applied.

However, this isn't the case and it just goes to show you how flexible and adaptive the penis shaft ligaments are.

If you haven't bought a penis extender device, we recommend trying out the manual stretching penis exercises because this will give you a good idea of how the stretch will feel when it is applied to your penis with the penis extender.

Any pain and problems stretching are due to the common mistakes that guys will make when doing penis enlargement, especially beginners.

The specific common mistake here is overstretching from applying too much force. Guys will think that they have to configure their extender to pull really hard on their penis to get results.

This couldn't be further from the truth.

The fact is, all you need is a light force applied for long periods of time.

Stretching harder will not do much for you, and in fact may stunt your growth by toughening up your septum ligament too much - if that happens it won't respond to stretching desirably.

One way to tell if you're overstretching from too much force is if you feel a sharp pain anywhere in your penis area. This goes for both penis extender devices and manual penis stretching.

For a single stretching session, discomfort will increase the more hours you wear it

This is true for all penile traction systems.

What's happening is that your penis - your skin, tissues, and ligaments - are all getting naturally fatigued from the workout you've been applying.

Every guy will experience this: When you first put the device on for their daily stretching session, you will feel fine.

Then after about 2-3 hours fatigue will start to settle in and you will start to feel some discomfort. If your a beginner this discomfort may settle in quicker because you're not conditioned to penis training yet.

This discomfort may be one of the expectations that we discussed just above.

Again, penis enlargement training is all about pushing yourself with care to avoid overtraining.

It's just like working out - there's just so many similarities.

You may feel the urge to stretch for more than 6 hours a day, but you have to have control over yourself to not do that.

You have to have the discipline to start off easy and then slowly increase the intensity and force setting on the device.

Don't jump into the deep end. Listen to your body, it will alert you if something is drastically wrong through pain. If you experience sharp pain, simply stop and call it quits for the day.

Wear it for too long and your crotch may be slightly irritated.

By combining the fact that you know discomfort will settle in the longer you wear it during the day with the amount of discomfort and pain that you're feeling, you can easily figure out when to stop stretching for the day.

It just so happens that this time happens to occur after 3-4 hours of stretching for most guys.

It's not surprising that discomfort settles in. After all, you're applying force to your penis, just like you're applying force to your muscles at the gym.

When you workout at the gym, it's not super comfortable, you're actively pushing yourself (causing yourself pain) to train yourself to become stronger.

Same deal with penis enlargement training.

Penis Extender Safety

Here is the only rule you need to understand when it comes to penis traction safety.

As long as you use extenders no more than 8 hours a day and do not stretch too hard, you will be perfectly fine.

That then raises the following question:

How hard is too hard?

At first this seems confusing and ambiguous because there isn't a force meter that tells you what the correct stretching force should be applied to your penis is.

However, there's a simple rule you can follow that will guarantee that you are applying the force that optimizes both safety and results.

The Optimal Force is the force that keeps your flaccid penis fully lengthened + a little extra.

A diagram showing how hard to pull your penis using a penis extender.
To apply the correct stretching force, apply just enough force to keep your flaccid penis fully elongated + half an inch more.

You can practice getting an idea for what this force is like for yourself, even without an extender.

Simply take your flaccid penis' glans (mushroom tip) in your hand and pull it out from your body, just enough so you're maximizing your flaccid length.

You do this by gripping your tip and slowly move your hand away from your body.

Once you reach the point where your penis starts resist that motion and pulls back against your hand, you've reached point where your penis is now fully elongated.

At that point, pull just a little harder by moving your hand out a little past it's current position to lightly stretch your penis and that will be the absolute correct force required for your penis extender.

This pulling force should not be painful.

This is another rule to follow.

If you feel pain, STOP what you're doing and reassess because you're doing something wrong and you need to fix it.

Using a Penis Extender to Treat Peyronie's Disease

Peyronie's disease is when your penis curves when erect and is not straight.

While the disease is not life-threatening, it is the source of self-esteem issues as well as possibly increasing sexual intercourse difficulty.

It hss been clinically proven that penis extenders are effective treatments to treat the curvature due to Peyronie's Disease.

Generally, the time frame to see a reduction in curvature is on the order of 6 months to a year.

Peyronie's Disease is very difficult to deal with. Fortunately, penis extenders are effective treatments to straighten the curvature.

Penis Extender Safety

How long do I have to wear the penis extender for, each day?

One of our most common questions, if not the most common.

The short answer:

4 hours daily, no more than 8 hours a day.

But why?

Given the scientific reasons for growth, you need to actually give your penis time to actually grow.

See, the penis can't grow during the time it's being stretched by the penis extender.

The penis extender is simply the tool that is used to stimulate the penile tissues, but the it's the human body that actually grows more tissue.

Think about what happens when you lift weights.

The exercises you do with weights stimulates the muscle tissue, signaling the body to adapt to increased workloads.

But it's the nutrition, sleep, and time not spent training that actually grows your bulging biceps and huge chest.

It's the same principle here.

How many days off can I take?

There may be emergencies or rest days that you need to take.

Or the logisitcs are simply not in your favor to wear a penis extender for a given day (meetings, intense travel, etc.).

But what's the general rule to follow when it comes to how many days a week you should wear the extender?

Aim for 6 days a week or more (At most take only 1 day off per week).


The power of averages.

Remember, you need to stick with the penis extender for 4 months or more.

Take too much time off in a given week and your weekly average for results and time spent goes down.

This average accumulates and affects your overall monthly results.

This means don't stretch 7 days a week, but then take one whole week off (Advanced users can actually modify their schedule to mix it up, but this highly discouraged for beginners).

You want to keep your rolling average on schedule.

You also don't want to give your body an excuse to not adapt and respond to the treatment training.

Taking a whole week off, then resming normally will interrupt your training and momentum and actually make results appear behind schedule.

When will I notice my first significant results?

In actuality, you're growing all the time, little by little.

However any growth from one day of training is so small that you cannot see it with the naked eye.

Therefore, the big prize (no pun intended), is more than 4 months.

However! You will start to notice size gains coming in as early as two weeks after using a penis extender.

We define this event as, when you say to yourself while looking in the mirror: "Hey, now that you mention it, I'm looking kind of bigger...!"

Will I get a "pencil penis" after using an extender?

The short answer?

Yes if you overdo the usage of the extender, no if you use it correctly.

So what does it mean to "overdo" using a penis extender?

It means you're doing one of two (or both) of these things:

  1. You're stretching too hard.

  2. You're stretching for too long each day.

How hard is too hard?

First of all, why shouldn't you stretch too hard?

Because it starts to toughen up a ligament in the penis called the "tunica ligament".

This ligament is basically a thin-but-durable, film-like material that wraps around the corpus cavernosum.

It is located inside your penis shaft and runs along it.

By physically stretching too hard - with lots of force - you're actually "toughening" it up.

Remember how we said that the body naturally adapts to external enivronmental changes?

Well, this is one way that it does so - the tunica actually hardens.

You do not want this to happen.

Why? Because you want your penis to grow longer, not stiffen up and have it's growth stunted.

Imagine that this part of your penis is now hard, it is effectively preventing the rest of your penile tissue from growing.

Sort of like a shackle or brace that is holding your penis bondage.

While tunica hardening is a good thing because it makes your penis more durable and stronger, it is not the best thing for actually increasing penis length.

Don't worry, there is one simple rule to follow to prevent tunica hardening:

Only stretch as hard as it takes to keep your flaccid penis fully lengthened + a very small amount more.

We've come up with this rule so that there's absolutely no confusion for you going forward.

This ensures that you're supplying enough force to actually do useful stretching work (keeping the penis fully lengthened, as that's when stretching actually starts happening).

And it also ensures that you don't overstretch by obscene amounts (by limiting the maximum stretch to a small margin above the threshold that penis stretching starts to occur).

How long is too long?

The general rule in the penis enlargement community is that you should not use a penis extender for more than 8 hours a day.

We here at PhalloGauge recommend you aim for 4 hours a day (a very practical and easy goal to strive for).

Why is this?

You have to remember, penis growth through hyperplasia does not directly happen from penis stetching.

Penis stretching is the method that allows hyperplasia to happen.

In other words, penis growth happens due to hyperplasia.

This means that more stretching does not equate to more gains.

In fact, you cannot let your penis tissues engage in cell hyperplasia while you're stretching, i.e. wearing a penis extender.

So you need to give your body a sufficent amount of hours in the day to switch over to hyperplasia events.

By not stretching for more than 8 hours a day, you meet this requirement.

Does it matter which extender I use?

Yes and no.

The answer is "no" if we make the following assumption:

You use the penis extender religiously and never miss a day.

If you satisfy that requirement, it really doesn't matter which brand extender by whatever company you use.

But that's a big assumption to make.

Because in reality, not all penis extenders are that easy to wear.

The following factors may affect your ability to wear the penis extender consistently everyday:

  • Comfort. Does it pinch, cut or scratch you?

  • Stealth. Can it be worn 100% hidden with people around you?

  • Ease of use. Is it a hassle to put on and take off? Does it take minutes or seconds to put on?

If these factors above are negative, they will effectively prevent you from wearing the penis extender every day.

So it's practically a requirement that the penis extender satisfies these factors above.

Therefore, we can modify the answer to the question, "Does it matter which extender I use?" to:

Yes, it matters - it must be comfortable, stealthy, and easy to use.

If you're looking to add a reasonable .7 inches to your penis through natural stretching, hyperplasia, and traction principles already used in plastic surgery methods - you may be interested in our extender that thousands of men already use.

In Conclusion

Penis extenders are the perfect tools that will guarantee your penis lengthening success.

They aid you in your penis training by allowing you to stretch for longer without affecting your day-to-day lifestyle.

They have been clinically proven to work and because all men are the same, there's no reason why it shouldn't work for you as well.

We covered the different types of extender systems (pulling and rod-based) how to use them.

We also covered the common things to expect when wearing it.

By applying these points covered in this guide, you'll practically be on your way to getting a larger penis in no time, just as tens of thousands of guys have done before you.
