Our test person (30 years old) began with a penis length of 10 cm (3.9 inches) in the flaccid and and 13 cm (5.1 inches) in the erect state.

In addition, he suffered from a slight , which showed during an erection with a 7 degrees deviation to the left. 5 years ago, the subject underwent .

The self test is scheduled for a period of 12 months and has now been running for 3 months.

My name is Enrico G. and I have been suffering for many years from a small penis. I'm an open person and I have no difficulty to get to know women. If it gets more intimate, however, I increasingly have problems to lower my pants.

— More penis size and more confidence thanks to PeniMaster Pro

This is not a preexisting blockade, I did not use to have such problems. Not for the first time I head somebody saying behind my back that my penis size was insufficient for the ladies.

When I heard about the test study on the new PeniMaster Pro, I immediately took the chance and volunteered.

PeniMaster Pro first application experience!

It took less than 3 days and the postman handed me the neutral package containing the penis expander. With great curiosity and high expectations, I opened the box and put the into the DVD Player.

Thanks to fail safe user guide, applying of the glans chamber was no problem. One can choose between two different techniques for generating the vacuum in the chamber.

Either the or with the . I opted for the rubber ball because it caught my eye.

Despite previous concerns about the many single items, the application was amazingly easy.

The penis glans slipped without any problems into the chamber on the first attempt and was connected to it immediately without pain. As a test I pulled a few times on the but it was tied firmly to the penis.

The feeling in the penis is quite pleasant, a slight under pressure can be felt, and the membrane is fixed like a second skin around the glans. It only takes a few minutes to get used to it and you do not even notice the PeniMaster Pro anymore.

Already at this early stage I had the first impression that wearing it for several hours would not be a problem.

"It's invisible, and pain free, so I can use it under my pants — even while I'm at work."

  • Results:

    • + 1.8 inches longer penis
    • + 0.6 inches thicker penis

I took the rod expander from the case and was pleasantly surprised at how many extension rods were already included. Overall, 14x extension rods in 5 different sizes come with the set.

I adjusted the PeniMaster Pro Expander rod to my penis length and pushed the base ring on my penis up to the pubic bone. Then I put the coupling socket on the rod end and mounted the glans chamber above the penis clip device.

Now my penis was tightly fixed and connected to the PeniMaster Pro rod expander. With the screws at the bottom end, I could easily increase or decrease the amount of pulling force exacted on the penis.

HOORAY, the penis penile extender is on!

I finished my first penis expander session after 2.5 hours. Although I could have worn it even longer, I did not want to overdo it with the first application.

By opening the valve of the penis slid easily out of his chamber and I was amazed at how big and thick, my glans was. It was almost twice as large as at the beginning of the session. The penis was slightly longer than the beginning too. This effect persisted even up to about 4 hours.

Another positive effect was that the sex I had with my girlfriend that night felt much more intense than usual.

This was certainly due to the fact that the glans was sensitized and, but also the optical magnification of the penis leading to more sexual arousal both with me and my girlfriend.

I was very excited that the PeniMaster Pro Expander rod was so quick and easy to apply and demount and also that the instant-penis-enlargement-effect was maintained even after several hours.

I was looking forward now to the next few weeks of use, and was excited to see what permanent penis enlargement I would be able to achieve with it.

1.month of application | PeniMaster Pro experience report

The first month is over and I've worn the PeniMaster Pro daily for 3-4 hours in the evening. In order not to overstrain the tissue and to get used to this kind of permanent traction I use only a small traction of 460g, which is level 2 on the built-in spring scale.

— High wearing comfort and easy handling

Throughout the application period no pain, bruises or other injuries have occurred.

Within the first 30 days I've once added a small 1x extension rod (0.5 cm | 0.2 inches). I could extend my penis from an initial 10 cm (3.9 inches) to 10.5 cm (4,1 inches) in the flaccid state and from 13 cm (5.1 inches) to 13.5 cm (5.3 inches) when erect.

My diameter increased from 3.5 cm (1.3 inches) (circumference: 11 cm | 4.3 inches) to 3.6 cm (1.4 inches) (circumference: 11.3 cm | 4.5 inches). I would not have expected it to work so fast. I was looking forward to the second month and was curious what would happen once I increased the wearing time.

2.month of application | PeniMaster Pro test report

I decided this month, to increase both the wearing time and the tension of the PeniMaster Pro . I wanted to see how my penis would react and if I could still improve growth.

My plan was to wear the discretely for 3 hours in mornings under my pants while I was in the office. I also wanted to wear the PeniMaster Pro rod expander for 2 hours in the evening at home. So I came up with a daily usage time of approximately 5 hours.

The first day I decided on the waist belt, as this version was the most suitable for me in my sedentary work . After I had put on the with a pleasant pull, I put on my pants.

The penis stretcher was absolutely invisible, and I had no restrictions on my freedom of movement. It did not give me any trouble while driving to the office, nor did it impair me at work while sitting or standing.

After 1.5 hours, I changed the carrying direction from left to right so that the penis was not only stretched in one direction. The wearing was so inconspicuous even to myself, that I almost forgot about it when I went to the toilet.

In the early evening, after about 7 hours of not carrying it, I put the PeniMaster rod expander on for 2 hours.

I increased the pulling force from 460 g (level 2) to 690 g (3). On the weekend I only wore the rod expander for 2 hours in the evening. Within the second month I have been able, thanks to increased wear time, to add a small extension rod (0.5 cm) 2 times.

My penis has extended in this period in the slack state from 10.5 cm (4.1 inches) to 11.2 cm (4.4 inches) and from 13.5 cm (5.3 inches) to 14.2 cm (5.6 inches) in the flaccid state. The diameter also increased slightly from 3.6 cm (1.4 inches) (circumference: 11.3 cm | 4.5 inches) to 3.7 cm (1.5 inches) (circumference: 11.6 cm | 4.6 inches).

A first small extension of the glans 2.6 cm (1 inch) to 2.7 cm (1.1 inches) was also noted. The penis curvature improved as well from 7 degrees to 6 degrees to the left.

For the third month, I further increased the wearing time and wanted to try wearing the PeniMaster Pro belt expander during the night.

3. month of application | Experience with PeniMaster Pro

My plan for this period looked like this: From Monday to Friday I only wanted to wear the belt expander for 8 hours overnight. At the weekend I wanted to wear the rod expander for 3 hours a day. In addition, I wanted again to increase the pulling force from 690 g (level 3) to 920 g (stage 4).

I opted for the carrying it with the . The advantage of this expander application technique during the night is that the penis is pulled down as opposed to the hip application.

Thus it is possible to lie not just on the back while sleeping , but also on the side. In addition, a change of direction is not required during the whole session.

After a short period wearing during the night became very comfortable and did not interfere. Even morning erections did not pose any problem for the expander.

The enlargement effect after the morning release of the PeniMaster Pro was enormous. The penis was a felt third longer and the penis glans was thick, firm and very large.

It was a real pleasure now in the morning to look in the mirror and see my penis. My girlfriend was of course also aware about what was happening. Our love life was now mainly happening in the mornings. At the weekend I put on only the rod expander for about 3 hours a day. With the increase of tension, there were no problems or pain with longer wearing times.

This month I have substituted the 2x 0.5 cm (0.2 inches) extension rods for one 2 cm (0.8 inches) rod. My penis was elongated from 11.2 cm (4.4 inches) to 12 cm (4.7 inches) in the flaccid and from 14.2 cm (5.6 inches) to 15 cm (5.9 inches) when erect. In diameter, I could also register an increase from 3.7 cm (1.5 inches) (circumference: 11.5 cm | 4.5 inches) to 3.8 cm (1.5 inches) (circumference: 11.9 cm | 4.7 inches).

With respect to the penis curvature I made a positive observation during the third month. The angle of curvature has increased further from formerly 6 degrees to presently 5 degrees to the left.

Even the glans diameter I found to be increased. From initial 3.6 cm, (1.4 inches) the diameter had increased to 3.7 cm (1.5 inches). The penis length also increased from 2.7 cm (1 inch) to 2.8 cm (1.1 inches).

I was looking already looking forward to the 4th month with the PeniMaster Pro . I decided to increase the tension of the rod expander again from level 4 to level 5.
