The penis extender science behind the X4 Labs is the generally well known principle of traction. As small amounts of stress are applied to the penis body, skin cells are broken down and forced to regenerate. During this same process the internal cavities of the penis body are forced to expand, allow for more blood circulation, and subsequently increase overall penis size. By increasing blood circulation to the penis, clients can also experience improved erection strength, and overall better sexual stamina but most importantly it increases penis length and girth.

These simple principles have been used for over thirty years by medical practitioners, and since 1995 urologists have applied the principle of traction for treatment of penile curvature as well as non-surgical penis enlargement.
