oh yeah! I did about 30 years ago when it was "different". I lost 28 pounds in a month and loved it. Then the Food and Drug Admin stepped in and had to change the chemistry and I tried it again several months later and gained 5 pounds. Like I said, it was 30 years ago, so I'm sure the makeup has changed again. It was nice - I had to go in and get weighed a few times a week and got injections of the hormone. Would I do it again? Yep! In fact, it would be interesting finding out who offers it here and how it has changed. Good Luck!
