Is X4 Labs The Best Extender?

In this article, I review the X4 Labs penis extender and discuss why it’s the most effective penis extender on the market. You may be already familiar with this brand or just a bit curious about penis extenders in general.

The good news is that penis extenders have indeed been shown to work in clinical studies.

About X4 Labs

To begin with, it is worth noting that the X4 Labs has been in business for more than a decade and has built a positive reputation online. This is what got me interested in trying their products. I figured they must be doing something right.

How Does It Work?

Penis enlargement can be achieved through the use of tension and the so-called principle of traction. This is precisely what the X4 Labs extender manages to achieve.

You simply to attach the device to your penis and adjust the tension settings until you can feel a firm yet comfortable stretch. The device allows for full control over the tension, which makes it perfectly safe for usage.

penis tractionThe tension results in cellular division and increased blood flow, 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 may 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 increased penis size, the increased blood circulation resulting from the use of the extender may also going to improve the erection quality and 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 urologists and sexologists.

X4 labs versus 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 competition.

One of the most important differences in the availability of a comfort strap that decreases the discomfort from wearing the extender. They are vastly superior to noose-based systems.

Thus, you can wear it pain-free all day. In addition, the straps keep the device in place, disabling it from slipping and ensuring the proper circulation that is needed for growth.

There are really only two extenders on the market I would consider using; X4 Labs and SizeGenetics. Both offer extra wide comfort straps and a variety of bonuses, accessories, and spare parts.

In terms of pricing, X4 Labs is the clear winner.

  • X4 Labs starts at $99.99 versus $199.95 for SizeGenetics.

An Extender for Every Penis

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 product before, you should purchase the starter edition. Other options include a Gold Premium kit and a Mini X4 that is perfect for individuals that have a penis length of four inches or less.

X4 provides several bonuses that make the purchase worth it. For example, the Penis Exercise Membership will give you access to over 30 video routines to improve your results. Other bonuses include the Better Sex DVD Collection and Instructional CD.

The best value overall is the Ultimate Luxury Edition which comes with numerous bonuses, accessories, and spare parts to keep you going for 6 months.

X4 Labs is unique because it has received the approval and the support of those in the medical field. Furthermore, the technology is clinically tested and shown to be effective.

Enhanced Product Design

x4 comfort strapWhile most penis extenders are designed to stretch the penis over a prolonged period of time, there are nonetheless significant variations in design. For one, X4 features a unique “comfort strap” which can make a huge difference in your well-being.

Because extenders are designed to be worn for several hours a day, more comfort can make the difference between success and failure. After all, not a lot guys want to have their penises stretched all day, and particularly not if it involves high levels of discomfort.

Product Rating

Here are my thoughts on what’s good and what could be better.


  • Effective Results: According to an article that appeared in Science Daily, a controlled study found that participants experienced an increase in 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.


  • Commitment. Getting results takes time. It’s not a quick fix like surgery but it’s also a heck of a lot safer and cheaper.

Guaranteed Results?
