The package arrived the very next day. The enema was well-packaged and came with plenty of dry ice. The instructions were easy to follow. I can’t say yet whether it was effective enough. I don’t have an appointment with a doctor who can have a stool sample tested until in two weeks. Before the transplant, I had to take magnesium every day, but that’s no longer the case. If I ever need another implant, I’d be happy to contact you again.
