Ever wondered if there’s a safe, non-surgical way to achieve permanent enlargement? You’re not alone. Many men explore traction devices like SizeGenetics (Official Supplier 🏆) and Phallosan Forte (Official Supplier 🏆)—but choosing the right one can feel overwhelming. Both promise results, but which one delivers?
One user spent months researching, torn between clinical endorsements and comfort claims. His journey mirrors yours: weighing durability, comfort, and proven outcomes. Whether you’re seeking length gains or curvature correction, understanding the differences between these devices is key. Let’s break down how they compare—so you can make an informed choice.
Overview of SizeGenetics and Phallosan Forte
SizeGenetics and Phallosan Forte are two leading penile traction devices designed for non-surgical male enlargement. Both use traction therapy to promote permanent gains in length and girth, but they differ in design, comfort, and clinical backing.
How They Work
- SizeGenetics relies on a rod-based extender system that applies consistent tension to stretch penile tissues. Clinical studies show an average increase of 28% in length and 19% in girth after 4–6 months of use.
- Phallosan Forte uses a belt-and-strap system with a vacuum bell for gentle stretching. It’s often praised for comfort during extended wear but lacks the same volume of clinical data as SizeGenetics.
Key Differences
- Design
- SizeGenetics has a rigid frame for controlled tension.
- Phallosan Forte offers a flexible, discreet design worn under clothing.
- Comfort
- SizeGenetics may require an adjustment period for strap comfort.
- Phallosan Forte’s vacuum seal reduces pressure points.
- Clinical Support
- SizeGenetics has published studies and medical endorsements, especially for Peyronie’s Disease.
- Phallosan Forte cites user testimonials but fewer independent clinical trials.
Wondering which suits your lifestyle? Consider whether you prioritize proven results (SizeGenetics) or all-day comfort (Phallosan Forte). Both devices require consistent use—6+ hours daily—for optimal results.
Key Features of SizeGenetics
SizeGenetics is a traction-based penis extender designed for permanent enlargement and curvature correction. Its medical-grade construction and adjustable tension make it a popular choice for men seeking non-surgical enhancement.
Design and Comfort
The device features a rigid frame with extendable rods, silicone straps, and a foam cushion for support. While it offers 58-way comfort customization, some users report initial discomfort until properly adjusted. Unlike vacuum-based alternatives, it's bulkier and less discreet, making it unsuitable for overnight wear.
Effectiveness and Results
Clinical studies show an average 28% increase in length and 19% in girth after 4–6 months of consistent use. The traction method triggers cytokinesis (cell division), leading to permanent tissue growth. For best results, wear it 6+ hours daily, whether in shorter or longer sessions—every hour contributes equally.

Key Features of Phallosan Forte
Phallosan Forte stands out for its unique vacuum-based system and comfort-focused design. Let’s break down its key features to help you understand how it compares to other devices.
Design and Comfort
Phallosan Forte uses a vacuum bell and elastic belt system, making it one of the most comfortable options for extended wear. The adjustable belt lets you customize the fit, reducing pressure points during use. Unlike rigid extenders, its flexible design allows discreet wear under clothing, so you can use it throughout the day without discomfort.
Effectiveness and Results
Clinical studies show Phallosan Forte delivers noticeable results, with users reporting an average increase of 4.9 cm in length over six months. Many also experience improved erectile function, including harder and longer-lasting erections. Over 90% of users express satisfaction with their outcomes, making it a reliable choice for gradual, consistent gains.
The vacuum system not only enhances length but also supports girth improvement, offering a well-rounded approach to enlargement. While it lacks the extensive clinical backing of some competitors, its user testimonials highlight its effectiveness for those committed to daily use.

Comparing SizeGenetics and Phallosan Forte
Choosing between SizeGenetics and Phallosan Forte depends on your priorities—whether it's price, comfort, or clinical backing. Both devices offer permanent enlargement, but their designs and user experiences differ.
Price and Value
SizeGenetics falls in the mid-to-high price range, offering a complete kit with straps and comfort accessories. It's built for durability with a rigid frame, but some users find it bulky for extended wear.
Phallosan Forte costs more upfront but includes discreet shipping and a user-friendly setup. Additional accessories like the Phallosan Plus+ add around $120 to the total price. Its vacuum system provides better comfort, making it a better value for long-term use.
Ease of Use
SizeGenetics has detailed instructions and adjustable straps, but it takes time to get used to the bulkier design. Wearing it discreetly under clothing can be challenging.
Phallosan Forte excels in comfort with its lightweight vacuum system. It fits snugly under clothes and adjusts to nighttime erections, making overnight wear possible. Most users report less discomfort compared to rod-based extenders.
