How does PeniMaster work?

penimaster extender


The working is very simple and employs the natural ability of the cell to divide and increase in mass as the key principle.

When you give exercise to a muscle, the stress created during physical exertion will result in small microtears in the tissue level.

If there is an injury, the cells would soon start the repair by a process called ‘cytokinesis’ or ‘cell division.’

Cells from the nearby vicinity will release chemical messengers to attract the immune system’s attention towards injury spot.

Soon the process of tissue repair happens, during which the cells undergo cytokinesis and fills the tears.

Since new cells are used to mend the previous space (tears), it would directly contribute to cell mass expansion.

This process, when occurring for an extended period of time would cause increase in penis size by up 3 inches in some cases.

This is called as traction-based therapy because the micro-tears in the penis are caused by intense stretching of the penile tissue using a penis extender apparatus.

The amount of force applied has to be optimized to create microtears but not the cause a significant injury to the penis, which is taken care of by the tension springs.

What results can you expect?

penimaster results

The results are depended upon various factors, and the most important of them is the amount of force applied, total wearing time and individual physiology.

While the third choice is entirely out of our scope, the first two can be manipulated by the user to score some good result.

The immediate results aren’t possible with an extender, but the user will notice an enlarged glans when used for at least 30 minutes.

If a person can use the PeniMaster extender for four weeks several hours a day (4+hrs), then penis girth is slightly increased in the flaccid state, and the user will notice temporary enlargement after an erection.

By the end of the fourth week, strong control over premature ejaculation can be achieved.

Upon using PeniMaster extender for 4+ hours a day for at least 6 months, then the user can see some of measurable results.

The thickness and elongation of the flaccid penis are significantly improved with enlarged glans.

By this stage, people suffering from Peyronie’s disease or other curvature related problems will notice their penis getting back into a straight posture while erecting.

Are these results permanent?

Penis extenders are working based on the principle of traction, and because of this reason, the result interpretation is slightly different from that of vacuum pumps3 or Viagra pills.

Technically penis extension means a change in the size of penis, i.e. the length and girth of the penis in its flaccid state.

If a penis size has increased in size while flaccid, then once it is erected, the size change would be multiplied approximately 70%.

The changes in size during the first few weeks, to be precise the 4 ~ 12 weeks’ time frame is not due to the actual cell division, instead only by tissue expansion.

Therefore the permanent result only arrives when you consistently use the PeniMaster devices for at least 12 weeks.

But once the change in length is achieved it would stay forever and increased cell mass wouldn’t go away.

Is PeniMaster safe?


PeniMaster is one of the most well-constructed penis extenders in the current market and all thanks to the precise engineering.

Each and every design aspect they have included in the package has a relevant research article which shows the technical data and clinical study results.

The higher pulling force is limited to less than 1500g in order to reduce any risks of an injury.

The body is constructed using superior medical grade plastic with fiberglass reinforcement to add durability.

The ‘Bio-functional’ design will ensure that the penis is elongated by exerting pressure in the right spots to spread the force evenly.

The glans is secured by a triple securing system which makes sure the penis head is fitted correctly to avoid slippage.

The pro-master comfort care cream would add an extra layer of comfort while fitting the glans chamber.

Penimaster is medically recommended for treating various penile curvature disorders, and the products are EN ISO 18485 certified.

Penimaster reviews

penimaster reviews

PeniMaster is very popular in Germany and some parts of Europe bagging an overall customer satisfaction index of 95% with an e-commerce rating averaging to 4.3 out of 5.

Some of the reviews scraped from the Internet will give you an idea about the post-purchasing feelings of other customers.

Dr. Rusland wrote on aiclegal as follows:

I have never been able to wear penis extenders with loop fixation for more than an hour due to the resulting pain. Extenders that come with a loop sensation have never been able to stay on, or the belts jumped out of the supports when there were higher tensions. Due to such experiences, I had concluded that there is no ideal extender for me. When someone introduced me to PenisMaster Pro extender, all these changed and I got an extremely new experience. I was able to wear this device for more than three hours during the initial encounter with it despite the strong pulling force. Also, the device stayed in position without any slippage for more than three hours despite the pulling force.

Terence wrote his experience in ahcaf as:

I bought mine in late September and received it Oct 4th. Definitely worth the price and wait. I’ve been researching on PE and was unsure of which product to pay for it. The price ranges for these products are definitely not cheap, and I somehow found out about PM Pro. I figured PM Pro must be the best one for my enlargement goals. With the PM Pro, you get the rod similar to Size Genetics which is $240 and the belt like Phallosan Forte which is $340. No brainer. Within going through the trials on having to figure it out; I was able to wear my device for 6+ hours with 15 min breaks on day one. Hope to see some gains in my future.
