As a pain-free and convenient method of insulin delivery, Generex Oral-lyn™ will allow individual patients to "fine tune" and then maintain their metabolism resulting in an improved quality of life. Accordingly, Generex Oral-lyn™ provides the opportunity for the establishment of a new and more efective diabetes treatment paradigm.
