X4 Labs Penis Extender ($399)

The famous penis enlarge extender from X4 Labs has been one of the top penis extenders on the market for the last 10 years.  This is one of the few penis enlargement methods to have been clinically proven, doctor approved, and CE certified.

Whilst employing the clinically proven traction system that other penis extenders use, the X4 Labs differentiates itself from the pack by also using patented methods to reach the highest standards of effectiveness – such as the custom loop fastener.  This and other techniques unique to this product mean that the X4 Labs penis extender provides a penis enlarge success rate of 85%.
