Dear Sirs: It is my absolute pleasure to endorse demal200. All my life I've suffered with severe allergic reactions to medications and was distraught with having to take a prescribed medication with so many side-effects in order to travel to Africa. I searched the internet until I found your product. While abroad my husband took the traditional medicine and complained of headaches everyday, while I used the demal200 with great success. My husband had to return to Africa and this time he used the remainder of my demal200, and was very pleased. You have customers for life.
