About us

The Jes-Extender™ was the first ever penis enlargement device using the proven non-surgical penis traction method. Originally used by doctors and plastic surgeons during post-op treatment, it became clear that its benefits are not only restricted to patients of penis enlargement surgeries. The penis traction device enabled any man to naturally grow his penis.

Since 1995, Jes Bech Müller has been producing the Jes Extender, now with over 500,000 satisfied customers worldwide. Still manufactured in Denmark using the finest quality materials, the Jes Extender is available in 6 different packages with a range of accessories.


DanaMedic’s business philosophy is that penis enlargement should be safe, as comfortable as possible, clinically proven and deliver visible results. We think that penis enlargement is a form of self-improvement – similar to working out at the gym and using beauty products. All products in the Jes Extender product range are safe, affordable and reliable to achieve visible results.
