Is X4 Labs The Best Extender? [Full-Review]

The fact that you are reading this tells me that you are either just a bit curious about penis extenders or else you’ve reached a point in your life where you are seriously looking for an effective way to increase the size of your penis. Now, I would almost be willing to bet my life on the fact that your penis is already big enough, but yes, I know, men are men, and many wouldn’t say No to a bit of extra length and/or girth.

The good news is that penis extenders have indeed been proven to work, despite all the reports claiming otherwise. However, I am not here to mislead you, I’ll tell you right now that they cannot and will not add inches to the size of your penis. If the thought of a modest increase in length appeals to you, then you might want to consider using one of these devices. I should also add that the studies I have looked at only recorded an increase in flaccid penis length, while none of the participants experienced any gains in terms of girth.


To begin with, it is worth noting that the x4Labs penis extender is manufactured by a company that has been making penis extenders for more than a decade. They have invested a considerable amount of money into research and have built a strong reputation online. This is what got me interested in trying their products.

X4 Labs must be doing something right because more than 1 million men from all around the world are currently using, or they have already finished using the X4 Extender. Astonishingly enough, X4 Labs are currently even offering men the opportunity to double their money: if you purchase one of their penis extenders and after using it as per their instructions you don’t notice a notable increase in length and girth, the company will refund you double the amount you paid.

Different Kinds of X4 Labs Extenders

There are 5 different kinds of X4 Labs packages. The one that you choose will depend on your personal needs. X4 Labs has been in business for 11 years, and a majority of their products are discounted. So, take a look at the following list of X4 Labs penis extenders.

How does the X4 Labs Penis Extender Work?

Penis enlargement can be achieved through the usage of tension and the so-called principle of traction. This is precisely what the X4 Labs extender manages to achieve. In order to start getting results, you will simply have to attach the device to your penis and to adjust the tension settings. The device allows for full control over the tension, which makes it perfectly safe for usage.

The tension results in blood flow stimulation, which leads to the growth of new tissue. The stretching breaks down tissue cells, which are forced to regenerate. As a result, penis length and width can be extended permanently by as much as several inches. The system has received the approval of medical experts and it has been clinically tested.

Apart from resulting in penis enlargement, the increased blood circulation resulting from the use of the extender is also going to improve the quality of the erection and the sexual performance. The principle of traction has been studied for many years and it is seen as the best alternative to surgical penis enhancement by many urologists and sexologists.

Benefits of X4 Labs Extender

As already mentioned, the results that can be achieved through the usage of the X4 Labs penis extension device are clinically proven. Following instructions carefully and using the extender on a regular basis can permanently increase penis length by as much as three inches.

X4 Labs has been in the device development business for over 10 years. The company has a proven track of successful product development. The purchase of its extender comes with a 180-day money back guarantee. In case you fail seeing the expected results, you can simply return the device.

The design of the device is exceptionally durable and it can be used for a long period of time. You will also receive the spare parts needed to prolong its life even further.

You can expect to see results four to six weeks after you begin using the extender. Some users have reported positive results after solely two weeks. Permanent increase will be noticed after the first month of usage and the most significant results will become apparent after three months.

How is the Product Better than Other Extenders?

Penis extension devices have been around for some time and you are probably wondering whether the X4 Labs extender is a better option than the extenders developed by other companies.

One of the most important differences is the availability of a comfort strap that decreases the discomfort connected to wearing the penis extender. Thus, you will be getting results without feeling any soreness. In addition, the straps will keep the device in place, disabling it from slipping and ensuring the proper stimulation of circulation that is needed for penis growth.

The X4 device kits are available in several versions and you can choose the one that is best for your needs. If you have never tried this type of penis extension before, you should purchase the starter edition. Other options on the market include a Gold Premium kit and a Mini X4 penis extender that is perfect for individuals that are having penis length of four inches or less.

X4 Labs provides several additional bonuses that make the purchase worth it. The Penis Exercise Membership will give you access to over 30 video routines that will improve the results produced by the traction device. Two other important bonuses are the Better Sex DVD Collection and the X4 Labs Instructional CD.

The penis extender developed by X4 Labs is unique because it has received the approval and the support of medics. The technology is clinically tested and you can expect permanent results without the discomfort connected to the usage of other extension devices. X4 Labs extender is 100 percent safe for usage and the money back guarantee means that you have nothing to lose.

Enhanced Product Design

While most modern penis extenders all work on the same principal, in that they are all designed to gradually stretch the penis over a prolonged period of time, there are nonetheless significant variations in design. For example, the X4 Extender features a unique “comfort strap” which you generally won’t find with other brands.

Because penis extenders are designed to be worn for several hours per day, this added focus on comfort can make a huge difference, and to a large extent, it can spell the difference between success and failure. After all, not many men want to have their penises in traction all day, and particularly not if it involves high levels of discomfort as well.

Participate In a Study for a Free Extender

Currently, X4 Labs is looking for willing participants to take part in a private study in exchange for a free X4 Labs extender. In order to claim your free device, you simply order the product; you use it for a period of 6 months as per the included instructions, and while doing to, you record your progress or lack of progress. At the end of the six months you submit the data to the company, and in turn, they issue you a full refund and you get to keep the extender free of charge.


Proven Results – According to an article that appeared in Science Daily, a controlled study found that all participants experienced a permanent increase in penis length after a period of 3 months.
One Size Fits All – The X4 Labs extender is designed to accommodate all penis sizes.
Enhanced Comfort – A unique comfort strap guarantees maximum comfort.

Price – Unfortunately, many men may find the price of these extenders a bit prohibitive with the cheapest version retailing for just below $90, while the Gold Edition is a whopping $249.00.

Guaranteed Results?

The X4 Labs penis extender delivers great results. Many credit their longer and thicker penises to this brand. As a matter of fact, X4 Labs is just as good as the competition, and it is head to toe with SizeGenetics.

In terms of performance, L4 Labs is just as good as SizeGenetics, which is considered the number one brand of penis extenders. A lot of men actually say that L4 Labs provides a higher level of comfort.

X4 Labs conducted a clinical study and asked men with penile erectile and size problems to participate. The study showed that the men in the study experienced a 10 percent growth increase after using X4 Labs for just 30 days. More than 99 percent of these same men experienced a 30 percent growth increase after using the product for more than 6 months.

For example, two men experienced an increase of 1.1 inches, and another experienced growth of 1.5 inches. These men used L4 Labs for a total of six months. This proves that men can expect differences in growth.


X4 Labs penis extenders are very flexible, and they work. The company sells many different customizable packages that pack a punch. If you want to increase your penis size and girth, it is strongly suggested that you purchase an X4 Labs extender. If you need a solution, but are on a budget, purchase a Deluxe Edition package. All in all, consider buying an X4 Labs penis extender.
