I was doing great the first month and shed a few pounds. However, after starting the second vial (the second month), I developed a swollen, red, and itchy rash at the injection site. I consulted with my doctor, who just told me to use an over-the-counter cream. It happens every single time I use this second vial. Not to mention, the package arrived warm with a melted ice pack, though I was told it was still safe to use. I'm thinking about giving up and switching to another company.
