X4 Labs Extender Review and Results [UPDATED]

In this article, I review the X4 Labs penis extender. Clinical studies demonstrate they permanently increase length and girth. However, misconceptions about penis enlargement are rampant on the internet.

The Truth About X4 Labs Penis Extender

As someone who isn’t well-endowed, I didn’t want to spend the rest of my life feeling embarrassed. The thought of having a big penis can excite a girl even before penetration. Perhaps I watched too much porn and envied those guys who would tear little girls up. The penis enlargement market includes bogus pills, creams, and even dangerous devices that promise a bigger dick. Why is X4 Labs any different?

Penis extenders have been clinically tested to permanently increase the size of the penis. You can confirm this with a Google search. I don’t consider myself gullible. After painstaking research, I invested in an X4 Labs Extender. It gave me an understanding of what’s possible with penis enlargement.

I’m aware that a majority of male enhancement products don’t work. However, penis extenders were something I needed to investigate. I wasn’t sure whether the science was real. In theory, it makes sense but would it work?

*Individual results will vary.

How It Works

The X4 Labs extenders work on the principle of mechanical traction which is applied to the penis. Basically, you apply a controlled amount of tension to the penis for a prolonged period of time. The force is gradually increased in duration and frequency. This isn’t some made-up concept. It’s a process that’s been documented in clinical studies.

The penis is stretched for several months until you achieve the desired result. The cells undergo a process known as mitosis that allows the penile tissue to grow. Expansion occurs in the blood vessels of the penis.

Which X4 Labs Edition is Best?

X4 Labs has a wide range of packages. This can be confusing for consumers like me. With each one averaging several hundred dollars, penis extenders are not cheap. I consider them an investment for long-term results. Anyways, which package should you get? It comes down to money and commitment Make no mistake, you’ll get the same results.

The only real difference is what you get for accessories, bonuses, and spare parts. Why does this matter? Well, at some point you’ll need to buy a spare rod as your penis grows. Or, you may need a new comfort pad as the old one has worn out. In a nutshell, the bigger packages give you more of what you’ll need.

Luxury Gold Edition

X4 Labs Gold EditionThe X4 Labs Gold Edition is a complete system packaged in a leather case. The extender is plated with 24-karat gold. There are two Velcro straps to secure your penis and extension rods to accommodate your growth. It comes with a cleaning kit for personal hygiene. If you have the money this is a great kit to own. It has everything you need.

You’ll get an instructional DVD and a manual that shows you different ways to wear the extender. There’s a $50 gift certificate for spare parts and an invite to the X4 Labs penis enlargement forum.

A second DVD called Penis Access shows you a bunch of penis exercises to accelerate your results. And let’s not forget the three packs of foam to use with the straps.

With the extender, you’ll be adding the extension rods as you make gains. I found them well-designed and easy to use. There’s plenty of spring tension to keep you comfortable. If you decide not to use the comfort straps opt for the rubber Noose. Just slide it inside the foam pads. The foam makes it comfortable to secure the penis head.

The Velcro wraps securely around the memory foam so you can quickly adjust the fit. In summary, the Gold Edition offers three different ways to wear it. There’s plenty of accessories and spare parts. You’ll be ready for your maximum results. Keep in mind is X4 Labs offers even greater tension (4200 grams vs. 2800 grams) than the extremely popular Sizegenetics system.

Premium Edition

The Premium Edition comes with all the essentials. You get three sets of the short foam pads worn with the straps. That also includes three sets of the long foam pads worn with the noose. I’d like to point out the foam pads are comfortable to wear and have surpassed my expectations. It’s gentle on the penis.

When you buy the Premium Edition you get a 5-year warranty. You’re protected from wear and tear and can use it as much as you want. If it breaks you’re covered.

As you progress, you can screw in the provided extension rod and continue to grow. I recommend using the cleaning pads to keep it clean. The instruction manual shows how to use it properly. You also get a second DVD, Penis Access, that shows you exercises to maximize gains.

The extender is light and feels smooth which is key to your comfort My favorite way to wear it is with the strap. It’s comfortable and doesn’t slip off.

Peyronie’s Edition Pro

X4 Labs Peyronies

The Peyronie’s Edition Pro corrects curvature of the penis. It works in as little as three months.

If the curvature of your penis is uncomfortable, a penis extender is an effective way to straighten it without resorting to surgery. A curved penis can make it difficult to have sex. It can lower your self-esteem.

This is one of their biggest packages. It comes with a vacuum pump which can improve girth and blood flow. You also get a vitamin E supplement, extra straps, nooses, tension springs, and a carrying case.

If you’re on a budget you won’t need all the extras. But, if you want to make a long-term commitment to penis enlargement then it’s a good investment.

Tension: 3900 grams

Deluxe Edition

X4 labs Deluxe Edition

The X4 Labs Deluxe Edition comes in a discreet package like all their products. Accessories include rubber straps, extension springs, comfort straps, nooses, foam cushioning, and an instructional DVD.

With the one-inch rods attached beginners will be ready to lengthen and stretch their penis. You can wear the comfort strap or the foam-cushioned noose. The Deluxe Edition will deliver the same results as all their extenders. They are designed exactly the same. The only difference is it doesn’t include the Velcro straps and bonuses found on the bigger kits.

I’ve worn the Deluxe Edition for a while and never had a problem with it falling off. Eventually, you may end up buying more rods or cushions. If you’re on a budget and want to get started this is a good choice. It gets the job done.

InfiniteFit Quad Support System Review

Comfort is one of the main selling points and what attracted me to X4 Labs.  There was no way I could attach something to my dick for 6 hours a day unless I was comfortable. The whole “no pain, no gain” philosophy doesn’t apply. The good news is the quad support system allows you to secure your penis with maximizing comfort. You’ll wear it all day long.

Having three different support options for your penis makes it one of the most comfortable extenders I’ve used. You can upgrade the base of the extender if you have a wide cock. I think X4 Labs really hit the nail on the head with the Quad Support system. It allows guys with any size penis to use it comfortably and effectively.

InfiniteFit Quad Support

One great aspect of their products is they’re lightweight and easy to use. However, they’re tough and durable. When you want to adjust the straps there’s a little clip on the cradle that locks them into place. This prevents slippage. Some of the cheaper penis extenders don’t offer this. However, I’ve found it important for a snug fit.

Benefits and Features

Some of the key feature and benefits include that have made it popular include:

  • Effective in increasing the length and girth of the penis by several inches within a few months
  • Approved as a Type 1 medical device with clinical trials for safety and efficacy
  • Recommended by enlargement surgeons
  • Durable in design coupled with safe materials
  • Safe and easy to follow instructions
  • Package includes spare parts as well as a private storage box and instructional DVDs

In business for over 10 years, they offer a 180-day money back guarantee and 24/7 customer support. They include discreet, free shipping to the United States, Canada, and the United Kingdom. If you’re unsatisfied, you will get a full refund. X4 Labs reviews are mostly positive.

If you’re a guy who’s unhappy with his penis size there’s a solution. You won’t have to feel ashamed for the rest of their life. As a teen, I was self-conscious about the size of my penis.

It wasn’t until later in life that I decided to try natural penis enlargement. I’m so glad I did. Remember, extenders have been clinically studied and guaranteed to increase your penis size.

I was skeptical when I first heard about them. After doing research I committed myself to six months of use. I wanted to see what I could achieve.

Bragging rights aside, there is nothing more flattering to hear my girlfriend say that I have a “horse-sized cock”. I love knowing that I can fill her up and give her amazing orgasms 🙂


With an extender, it takes months to achieve good results. I know a lot of guys want a quick fix but it’s not possible. In fact, I wouldn’t buy a penis extender unless you can commit to 6 months. Your penis can only grow so fast. In reality, you need to find the time. Fortunately, this is not as hard as it seems.

The first challenge to consider is finding the time to wear it 6-8 hours per day. How do you find the time? Well, most people actually have it. Think about it. If you’re sitting on your computer right now reading this article, you could be extending your penis.

The best time to it is when you’re relaxed and watching TV. You can even split up your routine. You could wear it for a few hours in the morning and then at night. The most important thing is to consistency. This leads to results.

Split your day in half. I get up at 6 am, make a cup of coffee, and sit in front of my computer for two hours. This is when I prepare for the day while getting in a quick session. I knock off two hours of my routine in the morning before I go to work. When I come home, I have 4 hours left. I  break that up into two-hour sessions. I make sure to have a break for dinner. I’ll usually finish off the night with the last two hours.

Once you’ve used your extender for 6 months and have made some gains you can incorporate the power hour. With the power hour, you wear it for a full hour with maximum tension. You do this right before you take it off. The power hour method can make a difference.

Maximize your X4 Labs Results

Despite how eager you are to use an extender, it’s best to prepare yourself. The following are the different guidelines for a guy who wishes to start ou.

First off, find out the length you’re starting with. Otherwise, you’ll have a hard time figuring out if you actually grow. As mentioned, the percentage of length increase between a flaccid and erect penis is variable. For this reason, guys should measure themselves when flaccid and when erect. Don’t forget to measure your flaccid and erect girth as well.

A journal is best to help you keep track of week-to-week progress. You can try measuring yourself once a week or twice a month. A journal also works best for keeping track of any penis exercises you’re using in conjunction. This helps you compare the effectiveness of each workout. For example, did you gain more jelqing? Or, did you find kegel exercises to be better in the long run?

A lot of guys find it easier to secure the extender with the penis in full view. This means removing all the pubic hair along your cock, making it easier to see the progress of your workouts.

This helps you with a more accurate measurement of the penis before and after usage. Fortunately, there are several known methods for grooming the penis. You can choose whatever strategy you feel comfortable using.

You need to warm up the penis first and get it ready for heavy use with a penis extender. I will be including further information on warming up and down in future articles.

Are The Results Permanent?

X4 Labs resultsIf used correctly, extenders can add as much as 1.3 inches to your flaccid length. Some guys have added even more through continued use. However, the additional gains tend to reach a point of diminishing returns. When I first started using the X4 labs, I had an erect length of 5.75 inches. After around 500 hours of usage, I measured 7 inches hard.

These gains are impressive for someone who’s new to penis enlargement. However, I followed the program to a tee and made it a priority. If you follow the guidelines then I don’t see how you won’t make gains. It’s certainly not rocket science. A misconception about penis extenders is that they will dramatically increase girth. This is simply not true. While you can add a solid inch in length, your girth won’t change much. A better solution would be to use water-based penis pump like the Bathmate. If you want to maximize length and girth then get both.

If you’ve never done male enhancement then you’ll probably gain one inch within 6 – 8 months.

This estimate is provided you wear it 6-8 hours a day. At the very least, wear it for six hours a day for 6 days a week. You could wear it every day but I would see how you feel. It would be a good idea to give your self a day to rest and grow. Noobies can expect to gain one inch in length if worn 6-8 hours a day for 6 days a week. 156 days worn 8 hours per day is roughly 1,330 hours.  The more you do it the easier it gets.

Is X4 Labs Safe?

Penis extenders are safe. Unfortunately, pills don’t work and surgery can be very dangerous and painful. In reality, the safety of penis extenders relies mostly on how you use it. You’re advised to read the instructions first before putting it on. It’s best to start off with light resistance during the first month. The only way I can see a penis extender being dangerous is if you apply a ridiculous amount of tension. You would be limited by the number of extension rods you used. Another risk would be if you decided to sleep with it and block circulation.

Repeat: NEVER wear the extender while sleeping. You don’t want to cut off blood flow to your penis. This can happen if you roll on your stomach.  However, you won’t have any problem wearing it during the day.  I use mine watching TV, cooking, eating, and doing other tasks. If you become uncomfortable than you’re using too much tension. It’s really that simple.

X4 Labs vs Sizegenetics

The two most popular penis extenders are remarkably similar. However, they do have some differences. Both provide excellent results and provide gains of 1-2 inches. In terms of pricing, Sizegenetics offers four different packages. They all come with the same extender. The packages are differentiated by the type of accessories, spare parts, and bonuses included.

With X4 Labs, there are 11 different packages. They are differentiated by the included accessories. Overall, the pricing and results between the two products are nearly identical.

X4 Labs is slightly more expensive but more comfortable to wear. As mentioned previously, X4 labs provide more tension with 4200 grams as opposed to 2800 grams.

My Results

My penis wasn’t horribly small as one might imagine. I measured 5.5 inches hard, which is considered average. To my eyes, it looked small. Especially to those horse-sized cocks, you see in porn movies.

I know I would never hang 10 inches. But even if I could gain an inch I would be happy. That’s a significant improvement and enough to hold my penis in two hands.

My girth was good. I was thick, to begin with so it wasn’t a priority. I just wanted to feel adequate in length. There’s no way I was spending everyday jelqing or hanging a bunch of rocks from my dick. It had to be safe and easy to use.

Most importantly it had to work. I tried a penis pump in the past when I was in high school. Unfortunately, I didn’t commit enough time to see results. From what I understand they only increase girth.

Like most guys I just want to be big enough to impress my girlfriend and have better sex. I want to be proud of my penis while being a little bit of a show-off. It’s either go big or go home for me!

Final Thoughts

Using an extender has been a rewarding experience. If I said it was easy to enlarge your penis I would be lying. X4 Labs is not a miracle. You have to use it nearly every day to get appreciable results. But it’s so worth it. Gaining an extra inch in 6 months is a big deal for most guys. That’s the difference between having an average cock and being huge. Not all women feel the same about penis size. Regardless, it’s good to know you have more than enough. If you’re dating a size queen you’ll be ready for her.

If can commit the next 6 months to penis extending than I recommend using X4 Labs. It’s reliable, easy-to-use, and comes with everything you need.  If I could only choose one, it’s the Premium package because it offers the best value. It comes with everything you need. X4 Labs offers five packages. This includes the Starter Extender, Gold Extender, Gold Premium Extender, Deluxe Extender and Peyronie’s Extender. Each one includes accessories.

Furthermore, all of the extenders include access to their penis enlargement forum. It’s a great resource where you can talk with other users and get answers to questions.  It also includes an instruction manual, quick start DVD, extra extension rods, and extra foam. You’ll grow and adjust to your size as you progress.
