How Each Device Works
Since the earliest days of weights and jelqing, men have searched for safe and effective ways to straighten, thicken, or lengthen their penises. The best modern penile enhancement products prioritise long-term gains and overall comfort. Rather than stressing penile tissues to the point of damage, they enhance blood flow, apply gentle pressure, and gradually reduce curvature. Learn how Phallosan Forte and PeniMaster PRO can accomplish these things and more.
How Phallosan Forte Works
Phallosan takes a multi-pronged approach to correcting penile curvature (Peyronie’s disease) and improving penis length and girth. This system has a vacuum sleeve that offers a secure attachment. Based on tissue expansion principles, its connecting belt applies gentle but continuous tension.
Designed for long-duration wear, Phallosan gradually stretches the penis without causing micro-tears, severe bruising, or other harm. Long-duration tension breaks down fibrous scar tissue (plaque) and promotes new tissue formation. Over time, progressive tissue remodelling reduces penile curvature and promotes longer-lasting, more robust erections.
Prolonged tension while in traction triggers the release of metalloproteinases. These enzymes facilitate the breakdown of scar tissue and accelerate tissue regeneration. Phallosan’s belt and vacuum cap system can be comfortably worn for hours. Men can use it to improve their penis health even while they sleep!
Built to accommodate penises of all sizes, this device wraps around the hips and cradles the penis with a wide but discreet ring. The tension gauge and suction pump fit over the penis and provide between 400g and 3000g of tension. You can adjust tension to suit your comfort level and health goals. This system also has cutting-edge indicator lights that reveal the exact amount of tension applied at all times.
How PeniMaster PRO Works
PeniMaster PRO also takes a multi-pronged approach to tension therapy, but it offers greater versatility overall. With this device, you’ll get a vacuum chamber and a modular system that incorporates a belt, rods, or weights for tension. With this flexibility, men can streamline their traction therapy to suit their comfort levels or conditions.
Designed for adjustable force application and offering three traction styles, the PeniMaster PRO comes with a base unit that’s shaped just like the penis glans. It offers snug adhesion even when users sweat. This anatomically self-adapting unit is positive-locking and works seamlessly with the brand’s comfort care oil to prevent chaffing, numbness, and bruising. Combined with vacuum adhesion, it provides a firm, locking fit.
You can connect this system’s glans cap to the traction belt to create tension between the leg and the penis or the shoulder and the penis that increases or decreases with movement. You also have the option of performing “bodybuilding” for the penis with a weight-pulling force generator. Starting with just 250 grams of weight, this exerts force on the penis that breaks down scar tissue and increases length. As you’re able, you can increase this force by adding weight in increments of 125 grams.

Clinical Evidence Explained
Clinical studies on penile tension devices (PTDs) prove their safety and efficacy. They also highlight the best use cases so that men can easily find the options suited to their needs and goals.
PeniMaster PRO Clinical Study
A controlled clinical study in the British Journal of Urology International (BJUI) showed PeniMaster PRO as both safe and effective for treating abnormal curvature of the penis (Peyronie’s disease). Researchers found that it’s a safe alternative to invasive surgeries for Peyronie’s disease. They also found that with certain application intensities, this traction therapy system can produce monthly gains in penile length of up to 1 cm as well as noticeable increases in penile girth.
Phallosan Forte Clinical Support
Clinical research performed by a German urological healthcare facility revealed Phallosan Forte’s ability to produce marked increases in penile length and girth. Of the study’s 26 participants, one showed significant penile curvature at the study’s start and noticeable straightening by the study’s end. Thus, this system may also be a suitable option in tension therapy for men with penis curvature. Researchers also found the device to be a safe and effective option for post-surgery rehabilitation.
Traction Methods Compared
Phallosan Forte offers dynamic belt-based traction. Phallosan Plus uses a threaded system, whereas PeniMaster PRO uses rods. It also offers movement-based tension with a dedicated vertical knee attachment.
PeniMaster PRO’s adaptable design includes rod-based, weight-based, and shoulder- and knee-based traction. Different traction styles may suit different user preferences or needs.

Which Device Is Better for You?
Phallosan Forte may be the better choice for you if you:
- Want higher traction force
- Prefer a dedicated vertical system
- Plan to wear your device for extended periods
Phallosan is so discreet that men can wear it even at work (provided they have light physical duties). This makes it easy to engage in the recommended daily tension therapy for optimal results. Given the system’s impressive maximum traction force, it’s a safe and effective option for men who’ve tried lower-tension options in penile therapies with less-than-stellar results.
Choose PeniMaster PRO if you:
- Want a lower starting price
- Prefer a longer warranty
- Want multiple options in traction (including weight)
PeniMaster PRO’s small, simple, and glans-shaped cup eliminates the need to shave the pubic hair for comfortable wear. With multiple tension options, this system also allows users to toggle between therapies as their goals and comfort levels change. It’s backed by clinical research supporting its use to correct curvature caused by Peyronie’s disease.

FAQs
Choosing the right medical-grade penile traction device isn’t always easy. High-grade and high-performing products often represent significant investments. In addition to spending, men are often concerned with factors such as safety, comfort, and ease of use. Check out these answers to frequently asked questions to make an informed selection.
Which is more effective for penis enlargement?
Both systems increase blood flow to the penis and trigger the release of enzymes that support new tissue formation. These activities can lead to up to 1-inch increases in girth and up to 2-inch increases in length, reduced scar tissue, and straighter, more functional shafts. Phallosan offers more tension for a more aggressive approach, while PeniMaster PRO offers greater versatility in tension therapy.
Which is better for Peyronie’s disease?
PeniMaster PRO has a published clinical study specifically focused on Peyronie’s disease, making it a strong option for men primarily seeking curvature correction. Phallosan Forte’s ability to correct penile curvature is backed by a controlled clinical study. It has a demonstrated ability to promote curvature improvement.
Can both be worn daily?
Both devices are safe for daily wear. In fact, for the best results, users should wear their traction therapy devices several hours a day, every day, for at least three to six months. Ideally, you should wear the PeniMaster PRO three to four hours each day, or the Phallosan for six to eight hours.
Is traction therapy safe?
When done correctly, traction therapy is very safe. Taking a gentle, gradual approach to breaking down scar tissue or enhancing penile length poses little risk of bruising, pain, numbness, or nerve damage. In fact, many urologists recommend traction devices following injury and surgery or to correct the progressive effects of Peyronie’s disease.
To ensure the safety of your traction therapy, it’s important to choose a device or system that’s backed by clinical research. The risks of traction therapy greatly increase when men use homemade devices, aggressive weight or jelqing techniques, or other extreme, self-directed treatments.
How long do results take?
One large part of ensuring the safety of traction therapy and other penile enhancement treatments is taking a slow, gradual approach. With Peyronie’s disease, it isn’t possible to break down plaque (scar tissue) overnight. Medical-grade traction devices create conditions that optimise penile health. They stimulate better blood flow, trigger the release of metalloproteinases, and support tissue remodelling.
With regular and consistent use, both devices can take up to two months to produce noticeable results. It often takes up to six months to fully remodel tissues, stabilise tissues, and ensure permanent outcomes.
