UK's first comfortable penis extenders - increase width and girth quickly safely!

The engineers at X4 Labs have perfected a penis stretcher method unlike any other.

Using the simple laws of physics, a strong tractive force is applied.

In order to maximize comfort, we have designed wide silicone straps (our exclusive ‘Super Comfort Strap’) to gently and firmly hold the penis in place while applying up to 1800g (3.9lbs) of tractive force.

This coupled with easy to follow instructions is guaranteed, to bring you permanent results while providing you with peace of mind.

Starting with the X4 Starter we sell a range through to the X4 Gold premium.
