What are penis extenders and who is ‘X4 Labs’?

A penis extender3 is nothing but a simple device with a penis support base, trusses, and springs.

They support the penis and stretches it within a safe limit to help the penis increase in size and also to fix curvature issues.

Penis extenders come in different specifications, of which the most important one is the spring tension, which determines the effectiveness of penis size increment.

How does X4 Labs work?

Penis extenders work using one of the well-known physiological phenomenon, which has been classically used for decades in bodybuilding.

Let’s take the most straightforward example and understand the working of a penis pump.

When you lift heavyweights in the gym, your muscles are exposed to stress which is slightly above the maxima it can handle.

This stress will create ‘micro-tears’ in the muscle tissue, which are invisible and painless.

The body’s natural repair system will kick-in and repair these micro-tears by a process called ‘cytokinesis’ or cell division which results in an increased cell mass.

So each time, when the tears get repaired, there will a slight increase in the size and which is why you look buffed up after several months.

Similarly, the penis is put to constant stress by the tension created in the penis extender, which over time would reflect as a 1~3 inches change in penis length.

The constant traction provided is the key for penis extension and for this purpose, the extender has to induce a strong stretching which is taken care of by the tension springs.

What results can you expect?

x4 labs results

Since this is a traction device, immediate results like that of a penis pump may not be available.

But the good news is that the achieved results would stay forever and doesn’t go away once you discontinue the penis extender.

It might take 2 ~ 4 weeks for the initial set of results to arrive, and in the very first week, a slight change in length (probably not measurable) would happen to the penis.

However, when a month and a half is over, you could see the visible change in penis length and could grow as long as 3 inches in some cases.

Slight pain might be confronted during initial usage, but depending on the comfort pads and tension spring, it will soon disappear once you start to get used to with it.

In some people, a slight change in girth is also observed while not comparable as that of the length since the tension is directly acting lengthwise while using a penis extender.

Are these results permanent?

Yes, penis extenders work by inducing a permanent anatomical change in the penis to cause a size change.

The process of cytokinesis imparts a permanent change in the penile tissue to increase the cell mass and thereby the penis size.

The size increment once achieved will stay, but if the penile tissue doesn’t get any exercise for a long time, then they might shrink.

But the user can safely discontinue the extender once the desired length is achieved and move to more natural methods to keep the penile tissues stimulated.

The traction therapy used in X4 Labs products is a proven theory and adopted by many other manufacturers to create similar products.

Those using X4 Labs extenders for treating Peyronie’s disease will get a permanent straight posture which would stay as such even when the traction therapy is discontinued.

Is X4 Labs safe?

Safety is the top feature that everyone would look for, especially when purchasing a penis extender.

If used as recommended by the manufacturer, penis extenders are very safe and don’t hold any chances of an injury.

It’s all up to the user handling that would determine how safe this device can be.

By design aspects, X4 Labs penis extenders hold ultimate comfort and safety standards to eliminate any risks involved while using it.

For those people with penis curvature due to Peyronie’s disease, they have to take special precaution to proceed at snails’ pace in order to prevent any damage to the penile tissue.

Small pain might occur, which is common while correcting the penis bend, but if intolerable pain persists, one must discontinue the device and consult a doctor.

X4 Labs is one of the most reputed penis extender manufactures in the western countryside, and all the trade is regulated under international standards.

According to user testimonials and reviews, all of their product line-ups are equally good at fulfilling the customer requirements.

Mike wrote his experience with X4 Labs penis extender in AICLEGAL as:

I have used the X4 Labs extender for quite some time now. It can be very uncomfortable if you don’t wear it in the right way. I make sure that I have strapped the device correctly to ensure my comfort. The strap shouldn’t be too tight to prevent instances of the head swell. I wear the device for a couple of hours and take breaks in between. So far, I love the results, and I can recommend it to anyone looking to increase the size that’s the length and girth of their manhood as well as solve other erectile dysfunctions.

Samsi4life wrote on a men’s healthcare forum as follows:

I have an X4 extender, and you can get a decent stretch for longer periods and a stronger stretch for short periods. You can gain from the tension over time, and I have been using this device for over 3 months now. I put some serious time into it and use it for at least 8 ~ 12 hours a day with 2 days off consecutively.
