What Results to Expect(Before/After)?

The principle of SizeGenetics‘ operation is based on the tension created on the penis due to the stretching of the metal rods and the operation of the springs. During the operation of the working elements of the device, the cellular tissues of the penis are stretched, which, in turn, increases the size of the penis.

SizeGenetics helps to increase blood circulation, which has the most positive effect on potency, enhances erection, and increases libido. Through these moments, a man becomes sexually strong and resilient. Many users have noted significant results: improvement in sperm quality, as well as an increase in its volume.

The next significant advantage that all SizeGenetics users experience is the permanent alignment of the curvature of the penis, which is the main symptom of Peyronie’s disease. Along with all physiological changes in the body, the psycho-emotional state of the man improves.

Another confirmation that the SizeGenetics device can solve the most common sexual problems among men is the presence of a huge number of recommendations made by leading American urologists.

SizeGenetics extender’s customer reviews with Before and After pictures is mostly positive. Clients claim that there are no side effects; they say about a high degree of effectiveness of the extender, first results become visible only a month after the start of treatment.

Did You Know?
SizeGenetics device was developed by a popular American company that has been actively promoting its products on the international market since 1995. During this time, the brand managed to gain the trust of millions of customers.

What are the results of using SizeGenetics?

First of all, the correctness of its fixing affects the efficiency of SizeGenetics extender use. Insert the penis in both fixing rings, additionally using special straps. Before you install the device on the penis surface, study the manufacturer’s recommendations in detail.

Do not forget that to obtain the desired effect, you shouldn’t stop using the device only with the first results. Even if you notice positive changes after a month, you should complete a full-fledged course using an extender, the duration of which is from 5 to 8 months. In this case, you need to wear the extender 5-10 hours a day.
 It is strictly forbidden to wear the extender at night . At this time, the pain threshold level drops to critically low levels, which can lead to mechanical damage to the penis. Also, many experts recommend taking herbal penis enlargement supplements while using SizeGenetics, which stimulates penis growth and improves the quality of sexual function.

How to Use SizeGenetics?

The SizeGenetics design is truly classic and easy to assemble. You have a base, rods, tubes for creating a loop, and a choice of silicone strap. You do not need to read the instructions to assemble the extender in a couple of minutes fully. First, you need to lubricate the head of the penis because you will fix it with a strap or silicone tubes.

When you fasten them, do not forget to wear comfort pads because, during use for several hours, you may be uncomfortable because friction is created between the tubes and your penis head. To soften the contact, comfort pads are used.

After you extend the penis into the ring of the base of the extender and fix the base of the extender on the head of the penis, you can select the rods to fix the extender and use it.

How to set up an extender?

It is very important to take the time to configure the extender for use. After all, if you configured SizeGenetics incorrectly, you:

  • May be uncomfortable
  • The extender may be ineffective
  • You may experience side effects such as redness of the penis, discoloration of the head of the penis
  • Putting the extender wrong, you can injure your dick

If you are a beginner, it is very important to initially adjust the length of the rods (for this, you have in the kit, there are rods of different lengths), as well as set the level of tension. It is not as difficult as it might seem at first glance.

I did this – at first, I tried different rods and looked at how much the length was correct by the length of my penis. Then he secured the base and set the lowest tension level by unscrewing the screws at the base of the extender. Further, he simply fixed the design and focused on his feelings.

IT WAS AN UNUSUAL FEELING since I put on the extender for the first time. Stretching the penis is something other than the jelqing and Kegels exercises I did before. Stretching is constant, and with constant force, I realized that the tension is very weak. And it will not be effective. With the length of the rods, I guessed after a couple of attempts, with a pull, I decided to be careful.

What did I do to set the correct tension level?

First of all, I unscrewed the screws evenly on both the left and the right. At first a little, I do not need to remove the extender for this. It’s important not to overdo it. You should feel traction but comfortable enough so you do not have swelling and discomfort.

After the first setup, I withstood no more than an hour. I could not think of anything except my penis, which was under tension. I hid the extender in my pants, wide enough and comfortable.

How I got used to the first week

The hardest part is the first week. Of course. I thought that the first time I’ll set everything up and I could not think about the fact that an extender is attached to my penis. But this was far from the case. It’s not enough to put on an extender once. It had to be removed every time I went to the toilet.

In principle, there are no problems with this – you break the bars, remove the base of the device and write, put it back on quickly and easily. But it bothered a little – I thought that now I’ll go to the toilet and again I will suffer to remove and put on the device.

It was possible not to remove the base, but to hold it with your hand – but it was inconvenient for me.

The second uncomfortable moment – I often thought that my device on the penis would bulge out of my pants. I specially put on wide slacks, which completely hid the presence of a device in my pants. It is convenient to put it on underpants, but I would not recommend wearing tight pants. It is both inconvenient and not aesthetically pleasing with the extender.

The next challenge is addiction. Rod extenders are inferior in comfort to vacuum devices such as the Penimaster PRO or Phallosan Forte. Due to the vacuum, they hold the head and there is no friction between the rigid parts of the extender and the head of the penis.

On the other hand, vacuum devices give a less tangible result and they need to be used much longer. What is the reason? Vacuum devices are very gentle and create very soft tension since they do not have a rigid structure. This allows you to wear the extender even more than 4 hours a day and you can sleep with it.

I tried using Penimaster PRO and Phallosan Forte, but the results were unimpressive. I used each of them for a month and this had a positive effect on my potency, my desire intensified, I began to have sex longer. But the length of the penis did not change.

Only after half a year did I return to the idea of ​​penis enlargement, but with a more effective SizeGenetics device. The rod extender’s rigid design helps stretch the penis not so carefully, but efficiently. Check out my Before and After results.

An operation to lengthen a penis or an injection is for the deceased

Judge for yourself, well, who can go for surgery, risk his health today, experience side effects for the rest of his life, and even risk it to make the penis longer? Clinics scream at the new technology – injection into a member. It’s about like Botox for girls, they inject it everywhere.

Or implantation, even the most sparing. I don’t even want to talk about it! Why is all this necessary if an extender such as SizeGenetics helped me increase my penis by 3 inches long and almost 1 inch wide?

How did I achieve these results with SizeGenetics?

It has been a long 6 months of work. I wore the device daily for 2-3 hours, while I also used the Bathmate HydroXtreme pump for about 15 minutes in the shower, and when I had time I did exercises Jelqing and Kegels. To achieve the maximum effect – I took VigRx Plus tablets, 1 pc every day. What for?

You must know that for the growth of the penis and the normalization of male sexual functions, you must work both externally and internally. This is the same as going to the gym. You exercise on simulators and drink dietary supplements to enhance the effect.

Call penis stretching – fitness for him. Indeed it is! Constant traction is a simulator, and SizeGenetics was produced by the same company DanaMedic, which came up with the first JES Extender. And SizeGenetics is its exact copy, only the packages are different. For example, SizeGenetics also has silicone tape that I wrap around a member to reduce friction while wearing the extender.

When you move, friction is always between the strap or silicone loops. Anatomically, an extender such as SizeGenetics is not ideal for removing friction. The penis is the delicate part of our body, and the head of the penis is the most sensitive. That is why it took me 2-3 weeks to fully get used to the feeling that the device is installed on your penis.

How did I use it everywhere and always?

I put it on trips when I sat in the car for 4-6 hours, I often put it on work – I was not distracted. I have sedentary work in the office, and none of my colleagues could suspect anything. I wore it most often at home; it did not bother me to relax. As a results, I have a bigger penis and a stronger erection.

The result is hard work

Natural enlargement of the penis is a job, no matter what. And I coped with it perfectly. I already wrote that the penis grew by 3 inches and this length does not go away, although I have not used an extender for half a year. Moreover, the erogenous member has become much larger than before and I can have sex 2-3 times longer than usual.

Psychologically, I began to feel much better thanks to SizeGenetics. You do not think the new sexual partner does not like your dick. Why? He is now long, fat, and even. You begin to relax and can hold ejaculation longer.

Another bonus is the ability to experience orgasms repeatedly. I did not possess this ability before, but it has become my norm today. I have an orgasm one by one and at the same time, I can restrain ejaculation. All this is the result of training my penis. Today I am doing reviews of many extenders since I consider myself not an expert, but an experienced user. If you have questions – write in the comments, I will definitely try to help.

  1. I have been wearing Sizegenetics extender for 4 months now and I have gained 0.8 inches in length. I’m happy with these gains. I was wearing the extender for 8 hours per day.

  2. Sizegenetics really works, believe me, but it takes time. After 300 hours of wearing I have gained about 0.3 inches in erected state.

  3. I wear it two times a day – 4 hours in the morning and 3 hours in the evening. I use 1200 tension mainly with a comfort pad because I found out that the silicone noose is bad for circulation.
