I had the same experience as others, being billed $59.95 for a 10 pack that I did not order.
Complained to the VISA card company, and I don't know the details but PE labs refunded my $59.95.
I still have the 10 pack which they claim cannot be returned.
As I understand it, this medication was not meant for humans, but for farm animals. The trial sample worked really well for my ED problem, but withins 20 minutes of taking the pill my eyes became very dilated and I got a headache from what seemed like very bright lights in my house. The vision problem lasted several hours. NO MORE ZIREX FOR ME!
