My ED cause is unknown by the doctors, or if they know they won't say, other then it is service connected. I believe it is from serving in the 1 and 2 Gulf wars. I have tried pills, but they didn't work.
All I can say is thank you, and my wife thanks you. We had all but given up hope. Your product is wonderful, a little tough to get on the first couple of times, but the best money I have ever spent in my life, thank you Again.
