Yes I have. It works, kind of - depending upon the batch you get. "Herbal" alternatives to licensed E.D. drugs are redundant now. Since Sildenafil Citrate (generic Viagra) is licensed to be sold in this country and can be found for less than the price of Golden Root or similar pills, then why risk your health with an unlicensed product?!?
Go to the pharmacy of your local supermarket or Boots / Lloyds pharmacy. Don't mess with something that contains who knows what!
