Penimaster PRO Review [2024]- My 6-months Experience and Results

I have been using Penimaster Pro (Official website) for more than 8 months now. During this time, I analyzed both its advantages and disadvantages, and now I will share with you the results of my experience in this post. In this article, you will find my impressions, tips, and tricks for using one of the popular extenders that you can find on the market today PeniMaster PRO.

Quick Edit
Penimaster Pro is one of the best vacuum-based extenders with sophisticated safety features. If you do not like noose extenders, it is a very good choice. It has both rods and belt-based designs to choose from. I would recommend going for the complete set as you can pick and choose depending on your convenience. It took me 8 months to get a 20% gain in length (almost 1 inch) but many users report similar results within 6 months. I would recommend using it for at least 1000 hours to get a permanent gain in length.

I’m not one of those guys who complain complex a lot about their small genitals. Yes, my organ is not as large as I would want it to be, but still, it is not a micropenis. However, to be honest, if I had the opportunity to increase the length and girth of my genitals in some magical way, I would not think for too long! But until recently, I was sure that the only really working method of penis enlargement was plastic surgery, which I would never have decided to do in my whole life. Of course, I heard about dozens of dubious ways to add a couple of cherished inches to a penis with some gels, creams, and pills, but I never believed in any effect of such drugs. Here is a pro tip: they do not have any permanent effect on penis length or girth.

How did I select the best way to enlarge my penis?

I came across the existence of the penis extenders while trying to find a scientifically-backed method to increase the length of the penis. I analyzed the characteristics and read detailed descriptions of the most famous brands of extenders, watched a bunch of videos of how to use them, looked at the “before” and “after” photos, and found out if there were any clinical studies that could prove medically the effectiveness of using these devices. As you can see, I have done some decent research. Therefore, even at the stage of ordering, I was quite confident that PeniMaster PRO stands out from other similar extenders, and now I am going to tell you why.


The criteria that I relied on when choosing

For me, the following nuances were principal when picking the optimal penis extender:

  • European / American quality: I was ready to spend additional funds, but it was important to get the original, not a fake.
  • Availability of clinical studies. I was not ready to risk my intimate health, trying to lengthen my penis with the help of non-tested devices.
  • Ability to use extender while sleeping. I realized that I would hardly wear it during the day when I went to the office. Therefore, I should have been able to stretch my penis during sleep.
  • The presence of real reviews I do not believe in miraculous devices that have absolutely no flaws. Thus, I analyzed carefully all the feedback from both satisfied and dissatisfied users.

PeniMaster PRO fully met these requirements, so I opted for it.


What is PeniMaster PRO and how does it work?

To begin with, PeniMaster PRO is a European product. The device was developed by leading German experts and production is carried out by MSP Concept, in Berlin, Germany.

This extender’s working basis is based on the principle of cell division. Penis tissues undergo gradual stretching (traction) due to the pressure exerted on them. This leads to mild microtrauma to muscle cells, which begin to divide more actively. As a result, a gradual increase in organ length and girth occurs, as well as an improvement in the blood supply to the cavernous bodies. Not only the size of the penis increase but also an improvement in erection and sexual stamina takes place. Also, the action of the device is aimed at solving a penis curvature problem and Peyronie’s disease. Besides, the extender is medical equipment, so it can be used to restore the body after undergoing surgery on the genitals, including after prostate removal. I did not have any of these problems, so my only goal was to enlarge the organ.


What is unique about PeniMaster PRO?

The basic principle of this extender is similar to other extenders, but it does have a fundamental difference that makes PeniMaster PRO a unique product. It is on sale since 2011, and during this time, no comparable models appeared that would use a similar feature. I am talking about the unique way to fix the penile glans, which is based on the action of vacuum, adhesion and latex membranes. Thanks to this method, the penile head is firmly fixed, which eliminates the possibility of its slipping. At the same time, there is no direct vacuum pressure on the penis tip, and it does not come into contact with the metal parts of the extender. Due to this setting, the user does not feel any pain or discomfort even with prolonged daily use of the device.


What is an adhesive system?

The introduction of a vacuum-adhesive fastening system has helped PeniMaster PRO to find its niche in the penis enlargement medical devices market and gain the recognition of many users. The principle of operation of this device is quite simple. A special gel is applied to the penile head and the latex membrane surface, which provides tight contact between them. Then, a manual vacuum pump ball is attached to the camera valve, and the air is pumped out of it. As a result, the latex membrane fits the head of the penis tightly, matching its anatomical shape and protecting it from direct contact with the solid parts of the extender. It only takes a few seconds to put on this device. Next, the penis needs to be fixed on the extender platform similar to other devices and worn for several hours daily.


The types of  PeniMaster PRO

There are several types of PeniMaster devices on the official website:

  •   PeniMaster Pro Basic: The set contains a glans chamber, a sluice ring, a latex sluice, a latex adhesion diaphragm, 2-sized split adapter, a pump ball, a hose, and a special gel for better adhesion. An important design feature is that the glans chamber implies foreskin frenulum protection. This product is the cheapest one in the line, and it costs 199 EUR.
  •    PeniMaster Pro Belt Expander System. The main advantage of this set is the ability to use a stretcher under your clothes when you are out or while sleeping. The kit includes the standard PeniMaster Pro Basic (without the hose) and a special elastic belt. There are 3 options for the belt fixation on your body: it can be fixed on the shoulder, around the waist, and under the knee. The price of this product is 269 EUR.
  •     PeniMaster Pro Rod Expander System. The set includes the classic PeniMaster Pro Basic system (without the hose), 2 adjustable metal rods with a snap ring, and 2 split adapters. The length of the rods is 2.8-12.8 inches; therefore, the device is suitable for a penis length of 2.0-11.8 inches. However, you may buy additional rods, so the total length of the extender is not limited. The product price is 289 EUR.  
  •    PeniMaster Pro Weight Expander. This device contains PeniMaster Pro Basic plus a shoulder belt, a coupling retainer, and a set of weights. There are 5 of them in the kit with the weight 125-500 g. You may use weights one at a time or screw them into each other, depending on the desired load. The total weight of all the weights is 1250 g, but it can be applied only by experienced users. This extender option provides a constant level of traction, and it can be used only at home. The product price is 325 EUR.  


What about clinical research?

As I said earlier, it was one of the fundamental factors for me at the extender selection stage. Medical testing was carried out by Dr. Ignacio Moncada (Madrid, Spain), as well as with Prof. Hartmut Porst (Germany) and American Specialists – Dr. Laurence Levine and Prof. Arthur Burnett. During the research, the main focus was on solving the problem of the penis curvature. The clinical study involved 93 men suffering from Peyronie’s disease. Participants used the device for 3 months. As a result, there was a decrease in the angle of the penis curvature to 50 degrees. Based on the data obtained, it was found that the use of PeniMaster PRO can act as an alternative to the operation to straighten the penis. The results of the study were published in the famous medical magazine “British Journal of Urology”.


Which PeniMaster PRO did I buy?

There are several types of this extender on the official website which differ one from another with the kit constituents. I decided to choose the Complete Package with rods and the belt because the basic one looked too simple to me. So, when my parcel arrived, I found there were all the details, the adhesion gel, the belt, the manual and the DVD with the instruction stored in a case. To be honest, I did not meet any problems when putting all the constituents together even without the manual because it is intuitively understood how to connect the rods to the platform.


How did I use PeniMaster PRO?

When I was at home and was not going to do any activities, I applied the extender with rods. The device is easy to put on: first, you need to place the adhesive tip on the head of the penis, then place the penis between the rods and firmly press the platform to the pubic area. In the end, you need to thread the tip into the groove at the end of the extender and tighten the rods to set the desired level of traction. Since I live alone, I did not see the point of masking the worn extender, so I didn’t particularly bother about the fact that its outlines can be visible under my home sweatpants.

If I had to wear the extender outside the apartment (for example, several times I had to come to the office just during the set), I used it with a belt. After fixing the adhesive camera on the penile head, I connected it to the belt, which can be wrapped around the waist or over the shoulder. I used to wear it around my waist. By the way, I used the same belt during sleep. It was quite convenient; I did not notice any slipping my penis out of the extender at night.  


Extra pluses

It is cool that in the kit there are membranes of 3 different sizes, so you may pick the one that matches your penile glans the best way. I used a suitable membrane for a month and a half until the moment when it ceased to provide a perfect fit for the penis. I was ready for such a scenario because I knew in advance that the service life of these parts of the extender is about 1-2 months. During this time, the user must determine the appropriate size to order the next membranes. For the 6 months that I used the extender, I needed 5 membranes. I suppose these extra costs for ordering membranes are fully justified. Any extender implies the presence of parts that require gradual replacement, and this is quite normal. After all, you get your comfort while using the device exactly thanks to these membranes.


Some pitfalls to avoid

What can I say about the applying process? It is quite easy to put your penis inside the device and rather comfortable to wear it, but you need some time to get used to the process. For instance, now I understand that the first couple of times I applied the gel incorrectly. I lubricated the head all right, but a few drops of gel usually fell on the foreskin. As a result, the skin of the prepuce was also pulled into the glans chamber, as well as the glans tissue. This caused a slight discomfort, which I mistook for the adaptation process issues and hoped that this problem and swelling would pass soon. Only after 2-3 times of such use, I realized what was the matter and began to avoid getting the gel on the foreskin. After this, discomfort and swelling no longer appeared.

Also for the first time, I didn’t immediately succeed in putting on the device correctly. I pumped out the air, but the head was not fully sucked inside. I could not understand what was the problem, so I had to fiddle with it a bit. But then I got used to doing it properly, pumping out the air with just one squeeze of my hand. It is important to ensure that there are no air pockets between the glans and the membrane because they can cause discomfort and swelling.



  •         The device was developed by German experts and passed clinical tests.
  •         Using the kit helps not only to enlarge the penis but also to straighten it and to improve erection.
  •         You can choose a kit depending on your needs – from the basic one to the more advanced.
  •       You will not find the unique vacuum-adhesive system in other brands’ extenders.
  •         The adhesion system helps you to fix the penile glans the most comfortable way and to avoid its slipping.
  •         PeniMaster PRO can be used for a long time daily without discomfort.
  •         It can be applied while sleeping.
  •         The kit with a belt can be worn under loose clothes.
  •         It is made from skin-friendly and non-allergic materials.



  •         This product is rather expensive.
  •         It is necessary to buy additional parts (for example, sluices).
  •         If the glans chamber is used incorrectly, discomfort and foreskin swelling are possible.


My results 

Before starting the using of PeniMaster PRO, my penis length was 4.9 inches and its girth was 4.3 inches. Now, after 6 months of wearing the tool for 6 hours daily, it became 5.5 inches and 4.75 inches resp. I guess, this is a fine result, and I am planning to apply the extender further for a year or so. 


My Final Verdict

For six months of use, I have never regretted that I decided to enlarge my penis with the help of an extender and that I chose PeniMaster PRO for this purpose. I believe that the device is fully coping with its task and I highly recommend it. You can buy it from their official website here.
