I am totally upset with Hyperzosin. They advertized an amazing breakthru in high blood pressure. I sent the postage for the sample bottle, went into the hospital and a pkg. of three bottles were delivered to my house that I did not order. They were sent back the day they were received as I was in the hospital and could not use them. Now they deny receiving them back and won't refund the $200 they charged my credit card without permission. This is not what was advertized on TV networks or Oprah as claimed. Everyone with high bp beware.
