Dr. Ameyda, an orthodontist with over two decades of experience, and Dr. Cenilo, an urologist with over fifteen years of experience applied their experience and knowledge to create the dsyon 4000™. Only one year after it's commercial introduction the dsyon 4000™ has become by far the most successful penile elongation therapy device.

Since the 17th century orthodontic dental braces have been used to correct alignment of teeth. Teeth positions are adjusted through the use of force, the force applied by the arch wire pushes the tooth in a particular direction and a stress is created within the periodontal ligament. The modification of the periodontal blood supply determines a biological response which leads to bone remodeling, where bone is created on one side by osteoblast cells and resorbed on the other side by osteoclasts cells.

The novel idea behind the dsyon 4000™ was to approach penis enlargement by using a similar device to gradually and permanently grow the corpora cavernous as well as the corpus spongiosum.

This technique allows for the growth to remain, incorporated into the corpora cavernous without any of the scarring side effects that plague other elongation methods.

Based on the latest orthodontal technology the dsyon 4000™ achieves incredible results, obtaining elongation of at least 1 centimeter over a four month period of daily night usage. As time passes elongation becomes faster with patients reporting up to 2 inches in one year.
The dsyon 4000™ is built with surgical stainless steel body (chromium 20%, molybdenum 0.2%, and nickel 9%) with silicone rubber comfort contact zones.

100% Stainless steel body

Most methods for elongations last only for a few hours and could be potentially dangerous.

There is no magic pill to enlarge the penis, as our grandparents used to say “good things come to those who wait”.

With the dsyon 4000™ elongation is permanent.. period.

Dr. Ameyda and Dr. Cenilo assembled a team of experts to fabricate the dsyon 4000™.
They personally oversee their fabrication as to guaranty the perfect and safe functioning of each dsyon 4000™
Each one is hand assembled and tested in our facilities in central Texas.

The device is 100% safe, with two independent security mechanisms.

No other method is safer an offers permanent results:

Penis Enlargement Facts


+ Excessive pressure causes vascular damage rather than a harder penis.
+ Pumping must be done very carefully to avoid injury: In some cases the testicles can be unexpectedly pulled into the cylinder causing severe pain and injury.
+ The rim of the cylinder can cut into the skin and over time cause damage to the ligaments surrounding the penis as well as deep skin lesions.


+ Analyses performed by Flora Research of California and by the University of Maryland have uncovered harmful contaminants in a number of "penis enlargement" pills
+ While "penis enlargement" pills may produce a placebo effect (i.e. a psychological effect of making the user think he has a larger penis, in turn increasing his confidence) there is no actual change to users penis size.
+ Some pills contain steroids that inflate muscle tissue in the penis with water, giving it a temporary appearance of increased size but can potentially produce deterimental long term side effects if used for long periods of time.
+ Injection of silicone into the penis and scrotum
+ Side effects including loss of sensation, inability to perform penetrative intercourse, scarring and deformation.
+ Injections of other substances, including collagen, mineral oil, and even KY Jelly may have similar effects, but also may cause extreme scarring and permanent disfigurement
