Review of Penimaster Pro: Safe and Effective Penis Enlargement Results?

Our in-depth exploration and analysis of the PeniMaster Pro unveiled its potential for delivering substantial, enduring gains in penis size.

Prof. Shariat has published over 1400 scientific papers in peer-reviewed journals. In 2014 he received the Matula Award from the European Society of Urology (EAU), and in 2017 the Gold Cystoscope Award from the American Society of Urology, probably the most important urologist award worldwide.

Many men grapple with shame or fear due to their penis size. Cultural and individual norms often intensify their worries about inadequacy and the ability to satisfy a significant other. These concerns persist despite reading countless studies on average penis sizes.1

Adding to the complexity are erectile issues post-prostate surgery and conditions like Peyronies disease, causing painful penis curvature. Finding a safe medical solution to enhance proportions and function becomes perplexing.2 Hence, PeniMaster products have garnered significant interest among men.

PeniMaster boasts a range of products promising increased length, girth, and correction of uncomfortable curves caused by Peyronie’s disease.3 While these claims hold some truth, it isn’t a straightforward solution. We dissect the nuances of penis elongation, presenting our research findings to help you determine if it truly addresses your concerns.

What Makes Us Trustworthy?

In the last two decades, Body Freedom Collaborative has empowered millions with informed choices for healthier living. How about tools promising increased penis size?

PeniMaster stands out, employing vacuum tension, traction, and increased weights.4 Our research team invested countless hours delving into penis extension, engaging with users, and examining market-leading devices. When new tools emerge, we scrutinize their superiority, confidentiality, and usability. While we abstain from personal long-term experiments, we stay abreast based on the newest clinical research findings on penis extension, ensuring you’re aware of performance and safety.

Just like all our health content, this review underwent rigorous scrutiny by our Medical Review Board. We vigilantly monitor PeniMaster and its competitors for the most current evaluation of their worth.

How did we evaluate PeniMaster?

We scrutinized it through the lens we employ for any penile enhancement tool. Safety and effectiveness took precedence, with cost close behind. Simplicity and confidentiality, though vital, ranked lower than the tool’s efficacy and safety.

Numerous studies demonstrate positive outcomes from diverse extension methods, including it’s use of pressure exerted by the rod, and vacuum suction force. We meticulously analyzed this information, and our team of testers assessed the company’s range of products for material quality and construction. We compared these findings with our evaluations of PeniMasters alternatives. Our team employed the devices on anatomical simulations for assessment, refraining from personal use.

Let’s delve into every parameter to gauge its performance.


Rating: 8.5 / 10

How well a penile elongation device works poses a unique challenge, given its outcomes are influenced by the individual’s initial anatomical structure. Yet, in instances of consistent and reliable gains, albeit varying from person to person, the extender’s efficacy becomes apparent.

PeniMaster products garner praise for their efficacy due to the company’s provision of two designs tailored to diverse extension and comfort requirements. Their methods, backed by positive outcomes in prominent studies, enhance their credibility substantially. Unlike the majority of alternative penis extenders which are reliant solely on using spring-loaded rods, which, though effective, carry inherent limitations, PeniMaster stands out.

Just like two individuals engaging in identical gym routines can yield contrasting results, factors beyond the extender itself come into play. Lifestyle choices and genetics, significant influencers, contribute to this divergence. Hence, for certain men, transformative outcomes might remain elusive.

Editor’s Note: The PeniMaster products have revolutionized the realm of penis extenders, offering tailored solutions and credible methods, even amid the variability of individual factors.


Rating: 8 / 10

In the realm of penis augmentation, a penis extender stands as a promising investment, especially when contemplating the considerable expenses men might bear for augmenting their girth or length. Amidst a plethora of alternatives, PeniMaster products emerge, albeit at a higher price point. Nevertheless, in comparison to counterparts like the Phallosan Forte, bearing a striking resemblance with its belt attachment and vacuum head attachment, it presents a significantly more attractive proposition.

Crucially, American patrons must recognize that the official website exclusively lists prices in Euro, subjecting the cost to fluctuations based on the prevailing exchange rates. As of the latest update, this currency shift works to the advantage of U.S. buyers, with Euro prices remaining stable while their dollar equivalents have markedly decreased. Notably, the PeniMaster website automatically performs this conversion, sparing customers the need for manual calculations.

In the competitive realm of penile enhancement products, PeniMaster stands tall, not just in terms of stature but also in pricing and performance. Compare for yourself:

  • PeniMaster Pro Rod Set: Priced at $282, it flaunts its prowess with rods.
  • PeniMaster Pro Belt Set: For $263, it embraces the power of belts.
  • Quick Extender Pro Deluxe Standard: Valued at $179, it relies on rods for its strength.
  • Phallosan Forte: At $379, it trusts in the might of belts.
  • Male Edge: Priced at $174, it harnesses the energy of rods.
  • SizeGenetics Value Edition: Yours for $200, it thrives with rods.
  • JES Extender Platinum: A high-end option at $1,000, it too commands with rods.


Rating: 7 / 10

Delving into the realm of penis extension demands utmost caution. These incredibly sensitive organs serve fundamental human purposes, such as eliminating waste and, notably, reproduction. Yet, in the pursuit of enhancement, the margin for error is vast. PeniMaster provides comprehensive instructions, yet mastering the device proves challenging. Hours of meticulous practice are imperative to ensure safe application. This learning curve is universal among penis extenders.

Optimal tension is pivotal. Insufficient tension yields negligible results, while excessive force may result in painful bruising, lingering for days. No shortcuts exist for safe usage, and precautions to avoid improper use are sparse. Patience, along with a considerable degree of dexterity, is indispensable. Following instructions meticulously and proceeding with gradual precision is paramount. The journey to enhancement demands nothing less.


Rating: 7 / 10

Penis extenders are anything but convenient. Its usage feels awkward, its presence clunky, and could be quite uncomfortable. Beneath your clothes, it molds a peculiar silhouette, a challenge to clarify things to a vigilant TSA agent if tucked in your luggage.

PeniMaster stands out not for its convenience, but for its exceptional customer service. Their distinction begins with a 30-day money-back guarantee, a window just sufficient to perceive changes if the product is reliably and accurately utilized. However, 30 days fail to promise permanence. For enduring results, a commitment of no less than 12 weeks with the device is imperative. Unlike other companies, such as Quick Extender Pro with a 6-month guarantee, The company secures your investment with a robust five-year warranty, affirming the device’s enduring quality.


Rating: 7 / 10

In the context of sexual health, preserving absolute privacy stands as a primary concern. No one wishes for inquisitive neighbors or roommates to stumble upon hints of their intimate medical necessities, be it from an overt shipment label or a branded box. PeniMaster, aligning with industry standards, ships its products in plain, untraceable packaging that conceals any identifiable return information.

Its website utilizes cookies for tracking user activity, but it’s crucial to emphasize that this tracking and site usage data remains confined to its platform. Throughout your purchasing journey, they meticulously secure your data.

What exactly is PeniMaster Pro?

Hailing from the innovative minds at MSP Concept GmbH & Co., a renowned German company, crafts medical urological marvels that cater to both health and aesthetics.

In 2011, spurred by invaluable user input on the original PeniMaster, now dubbed PeniMaster Classic, the Pro series emerged. It offers a range of products designed for traction, sculpting, and bolstering, akin to “penis sculpting” through weights. These tools can be seamlessly integrated to create a comprehensive and dynamic regimen for enhancing penile dimensions.

Is PeniMaster Pro a credible option?

Maintaining a healthy dose of skepticism proves essential when evaluating companies promoting products for penis enlargement. The internet teems with dubious enterprises peddling extravagant assortments of placebo pills and false elixirs, all designed to create the mere facade of efficacy to drive sales. Nevertheless, PeniMaster Pro boasts a commendable track record regarding customer service.

Beyond its efficacy, any issues that may arise during the utilization of their devices find swift resolutions through the diligent support team. We encountered affable and expeditious assistance from their customer service representatives, mirroring the consistently positive reviews shared by fellow device users.

Does PeniMaster Pro work?

It works by subtly enhancing the penis, primarily in length rather than girth. While a leap from five inches to ten is unrealistic, an additional inch might be attainable, contingent on your usage and individual physiology.

It harnesses traction, a method substantiated by numerous studies affirming its effectiveness.5 This innovative approach focuses on elongating the penis, predominantly utilizing a belted tension device with rods, with the potential for marginal girth augmentation through consistent application.

The methodology behind extenders revolves around three key elements: traction, weights, and fixation.


PeniMaster Pro’s Belt and Rod Expander systems delicately stretch the penile tissue, inducing microtears that lead to substantial growth after healing takes place.


Utilizing gravity and various weights, this method vertically stretches the penis, generating microtears that prompt the growth of new tissue during the healing process.


Incorporating vacuum suction, adhesion, and latex, fixation techniques secures the glans firmly, eliminating pain. This suction pressure enhances blood circulation, induces microtears, and ensures uniform tension distribution throughout the penis.

While it is not a miracle solution, the company refrains from making grandiose promises, a reassuring sign for discerning customers. Their devices are designed for gradual, consistent use spanning several months. Multiple users report nearly an inch of growth within six months, with results appearing to be enduring.

How does PeniMaster Pro work?

In a groundbreaking approach, this program transforms penile augmentation by fixing the glans and then applying tension along the length of the shaft. This induces tiny microtears within the penile tissue, triggering natural cell creation. Over time, the body adds tissue during the recovery phase, resulting in significant enlargement and strengthening, as proven by a Mayo Clinic-sponsored 2020 study. After just six months of consistent, moderate usage (30 minutes, two times a day), participants experienced a remarkable 2cm increase in length.6 The PeniMaster Pros innovative systems ensure safe and effective enlargement through a combination of extension techniques.

Central to the PeniMaster’s success is its rod-based stretching method, which achieves symmetry along an axis in the applied force. This balanced tension, exerted equally from both sides, enhances comfort and relief during treatment. Moreover, this symmetry plays a pivotal role in achieving desired cosmetic outcomes, particularly for individuals with smaller than average size penis or Peyronies Disease.7

Intriguing Insights into PeniMasters Mechanics

The PeniMaster Pro Basic, dynamically links the glans and penis, catering to most adults based on their glans size. But, clarity is key: it (with its bulb attachment) isn’t the sole catalyst for penis growth, a common misconception among our clientele. Our testers observed a communication gap on the website, where the constraints of using just the PeniMaster Pro Basic were not adequately emphasized. To truly unlock enlargement potential, the rod or belt expander system becomes indispensable alongside the device.

Applying the PeniMaster Pro device

Our staff discovered the instructional DVD’s profound utility when dealing with the PeniMaster Pro, a device that can pose a steep learning curve for first-time users.

Usage Guidelines:

  1.    Apply lubricant sparingly to the penis head and inside the enclosed latex chamber.
  2.    Firmly compress the spherical pumping device and secure it to the sealed rotary valve.
  3.    Rotate the glans enclosure and pressure pump together; compress the ball pump to its maximum.
  4.    Release the pressure gradually, creating a subtle vacuum that securely secures your glans within the enclosure.
  5.    Detach the ball pump; ensure the valve stays closed.
  6.    Configure the rod extension system; enter your penis, starting with a length equal to your stretched non-erect penis size and an additional 1.5 centimeters.
  7.    Insert the extension rods, and attach them to the slim portion of the coupling socket. Adjust traction using the spring balance shorter rods for lighter traction, and longer rods for stronger traction.

How soon will results become visible?

Discovering the timeframe for visible progress varies. Most users witness gains after consistent daily usage for a few hours over a few months. For optimal results, we advocate employing the extender for a minimum of six months, aligning with other products in the same category.

Reports from numerous users highlight visible changes within mere weeks of adopting the PeniMaster Pro. However, it’s vital to note that these early gains are temporary. Your body adapts initially, but substantial, enduring enhancements require patience. Genuine progress becomes evident after a minimum of 12 weeks, peaking near six months of unwavering commitment. Both length and girth show remarkable, lasting improvements.

Dedication is key. Make using it a daily ritual, investing a few hours per day. This consistency is your pathway to enduring transformation. Embrace your journey; unlock the potential for lasting change.

Is it safe to use PeniMaster Pro?

Adhere meticulously to the guidelines and heed your body’s signals. Proper use should yield no discomfort; each product includes a comprehensive guide for safe, effective application.8 If discomfort persists, common errors in the learning curve might be at play.

Establish a meticulous routine for donning and doffing the device before extended use. This method, in tandem with an accurate application, guards against entrapment or undue force during post-stretching removal.

Missteps, like excessive pulling forces before readiness, can result in a bluish-glans discoloration. Temporarily refrain from using it until symptoms fade before making adjustments.

PeniMaster Alternatives

Penis extenders have evolved, with the PeniMaster Pro emerging as the safest and most effective choice. While several other devices, methods, and approaches allege to enlarge the penis, some prove effective but pose significant risks. Others lack sufficient research for a verdict, and some just simply fall short.

Let’s explore the wider scope of devices initially, and then we’ll examine alternative options for you.

Penis extenders

Penis extenders flood the market, with options ranging from rod to belt systems. Few brands, however, combine both approaches, a unique trait exemplified by PeniMaster. While some competitors offer lower prices and comparable effectiveness, they often lack the force potential and extensive warranty synonymous with PeniMaster.

Before delving into the top contenders, explore this informative chart detailing the landscape of these products.

Phallosan Forte Most Similar
This device closely resembles the PeniMaster system in functionality and design. It utilizes vacuum suction along with a belt mechanism to administer traction therapy. While it may be a bit pricier than the PeniMaster, its setup process is somewhat complex, and not everyone will make full use of the included accessories.

It comes with a 2-year warranty but when compared to Quick Extender Pro’s lifetime coverage, and PeniMaster’s 5-year warranty they both surpass it by a considerable margin. Moreover, a mere fourteen-day guarantee isn’t a reasonable evaluation period.
Quick Extender Pro Best Values
Your go-to choice for a cost-friendly, no-nonsense rod system, impresses with a lifetime warranty covering product defects. However, it lacks the option to incorporate additional weight or vacuum pressure and may not offer the utmost comfort. Nevertheless, it delivers effectiveness at a reasonable price.

In the dynamic realm of male enhancement devices, Danalife, a prominent Danish company, proudly introduces its innovations: SizeGenetics, JES Extender, and Male Edge. Each bears the distinct Danalife signature – a robust two-year warranty and an unyielding six-month guarantee, uniting them in a commitment to excellence.

sizegenetics offer
SizeGenetics Popular Choice
SizeGenetics, reminiscent of Quick Extender Pro in structure and material, falls short due to its lackluster comfort accessories. While the promise lingers, the delivery falters.
MaleEdge Budget Option
Male Edge, the most economical choice among the trio, belies its affordability with compromises in quality. Our testers handled components that felt fragile, a stark departure from durability.
Jes Extender Premium
JES Extender mirrors SizeGenetics in its foundational form, yet ventures into opulence with extravagant versions boasting titanium rods or lavish gold and platinum plating.

Exploring Methods to Enhance Penile Size: Debunking Myths

Penis pumps, often touted as tools for enlargement, prove to be myths. Their purpose lies in treating erectile dysfunction, enhancing blood flow for temporary, albeit illusory, size gains.

Extension surgery offers potential size increases, but the perilous use of artificial fillers and cadaveric tissue carries immense risks. Refusal and tissue death loom large, exacerbated by non-standardized procedures. 9

Jelqing, a set of stretching exercises, claims to lengthen the penis. Despite lacking scientific backing, enthusiasts persist, despite gains appearing ephemeral. The method demands precision and patience, yet its efficacy remains dubious.

Male enhancement pills, akin to PDE5 inhibitors, promise size augmentation. However, their impact pales compared to Cialis or Viagra. Any perceived size increase results from heightened blood flow, not actual growth.

In scrutinizing these methods, the truth emerges: quick fixes evade reality. Science and patience outweigh risky endeavors, offering a perspective grounded in truth rather than false hope.
