"I have had over five years of experience with penis enlargement pumps, patches and even extenders. Pumps and patches didn’t work for me and my previous extender wasn’t very comfortable.

The X4 Labs penis extender was the only product that worked for me, their silicone tubing and even Comfort Straps were more comfortable than my previous extender. The best part is I never had to buy spare parts because everything I needed was included in the package."

"My husband was serving overseas and I decided to order the X4 Labs extender for him, particularly to treat his penile curvature.

When he came back from his service, I noticed drastic changes and his sexual drive was greater than before."

"I’ve had several surgeries in order to reconstruct my penis. My doctor recommended the use of the X4 Labs penis extender as a post-operative device.

I have most likely gained more in length and girth from the penis extender than from the surgery itself."

"Recently diagnosed with a mild case of Peyronie’s disease, I began to research a variety of non-surgical methods to treat penile curvature.

The X4 Labs penis extender immediately gained my attention and has corrected approximately 95% of my penile curvature. I no longer suffer from erectile dysfunction and my urologist now recommends the X4 Labs extender to many of his patients."

"Nothing comes easily, however; three months into my treatment program I noticed tremendous gains in length and girth.

I had gained two inches in three months and I was amazed by the efficiency of the penis stretcher. I used the Comfort Strap Technology but I loved knowing that the silicone-tubes were available to me."
