#9 Rated Penis Extender: X4 Labs Extender

For years, X4 Labs Extender was considered a staple in the penile enhancement industry—a flagship model for traction-based lengthening that earned attention for its durability, adjustability, and high-tension capacity. Once marketed as a premium U.S.-based solution for men seeking non-surgical enhancement, it even came with a medical certificate and a reputation for quality. But fast-forward to today: X4 Labs is no longer in production. The website is defunct, the products are increasingly hard to find, and customer support has gone silent. This review provides an honest postmortem on what the product did well—and where it ultimately lost ground.

What is the X4 Labs Extender?

The X4 Labs Extender was a rod-based penis traction device designed to increase penile length and help correct curvature (such as Peyronie’s disease). It used an adjustable base ring, tension rods, and a noose-style or comfort strap system to secure the glans. Users were expected to wear the device for several hours per day over the course of multiple months. It was marketed as both a cosmetic enhancer and a therapeutic device, with models like X4 Labs Standard Edition, Gold Deluxe Edition, Peyronie’s Treatment Edition, and Extreme Edition (high-tension model).

Our Ratings for X4 Labs Extender

What Made the X4 Labs Extender Notable?

Historically, X4 Labs was known for delivering results—if you were committed. With its double strap system and sturdy aluminum alloy rods, the device could generate a high degree of traction (up to 4,000g on some models), which placed it ahead of much of the market at the time. Its double strap system was considered an innovation during an era dominated by crude noose systems, helping to raise standards in the industry.

The device was also medically endorsed and carried CE marking, giving it credibility in a market often plagued by questionable products. For many years, it was considered a reliable option for men seeking non-surgical enhancement or treatment for Peyronie’s disease.

Performance and Results

With its sturdy aluminum alloy rods and double strap system, the X4 Labs Extender could generate a high degree of traction (up to 4,000g on some models), which placed it ahead of much of the market during its peak years. Users who followed the standard protocols of 4-6 hours daily wear reported moderate gains of 1 to 2 inches in length over the course of 6–12 months.

The device was especially popular in communities like ThundersPlace and PEGym between 2010–2018. However, performance came with caveats: slippage was common, learning curves were steep, and long-term consistency was difficult without discomfort or wrap customization. For committed users who mastered the device’s quirks, results were achievable, but the journey wasn’t always smooth.

Comfort and Wearability

Comfort was always a weak spot for X4 Labs. While the double strap system was marketed as a major innovation, users frequently complained that the silicone noose caused pinching or numbness, the comfort strap wore out quickly, and the base ring lacked ergonomic shaping. Without third-party wraps or gauze, extended wear was rarely tolerable.

The device could produce glans pressure, bruising, or fluid buildup if not adjusted precisely. Many users resorted to DIY modifications to get the device wearable for more than 1–2 hours at a time. In today’s comfort-optimized landscape, X4 Labs now feels clunky and outdated, reflecting how significantly the industry has evolved in prioritizing user comfort.

Value and Cost Considerations

Pricing at the time of its availability ranged from $119 for the Starter Kit to $299+ for the Deluxe or Peyronie’s Editions. In its heyday, this was seen as fair given the build quality and clinical backing. However, considering it now lacks support, warranty activation, or available parts, any current listing should be treated as final-sale collector’s items.

The once-competitive pricing now feels high for a product with no institutional backing. Potential buyers should be aware that they’re purchasing a discontinued product with no guarantee of support or replacement parts, significantly reducing its value proposition compared to active competitors.

Customer Service and Privacy

X4 Labs was discreet in its packaging and customer privacy. It shipped under neutral billing names and arrived in plain boxes—something it did well, even in earlier years when other brands hadn’t caught up. In the early 2010s, X4 Labs had a decent reputation for service, but the situation declined sharply. Numerous Reddit and PEGym posts from 2021 onward mention unresolved cases, ghosted refund requests, and unshipped orders.

Today, there is no official customer service. Any attempt to engage with the company leads to dead pages or bounce-back emails. Due to its now defunct status, resellers’ privacy practices may vary, creating inconsistency in what was once a strength of the company.

Final Thoughts

The X4 Labs Extender once stood as a pioneer in the penis traction space. It offered above-average performance for its time, and its double strap design helped raise the standard in an era dominated by crude noose systems. But times have changed. The extender market now emphasizes comfort, guided support, and real-time digital integration—features X4 Labs never evolved to include.

With no customer service, no production, and no warranty support, what’s left is a once-great product that’s now obsolete. X4 Labs Extender earns a 59/100 in 2025. It’s a piece of enhancement history—not a viable choice for men serious about modern, supported, long-term penile growth.
