I took one dose and it made me so sick I thought I was going to die. But had no idea that they would send a second months supply. I would not have cared much had they not sent the second month, and then refuse the unopened shipment was returned back to me. They also haded no paper work at all with eighter shipment, no nothing, they not want to have any conections after the first shipment. I had to Google to find them and then all they tryed to do is sell more.
