Does Calotren Work?

It seems like there are a lot of supplements, especially weight loss supplements, that don’t actually work. I am trying to find one that does, and that doesn’t have a lot of possible side effects. So far I am leaning toward trying Calotren. Can anyone tell me whether or not this actually works? I haven’t heard a lot about it in the past, I just came across it when I was looking for information on the various weight loss supplements on the internet. It looked like something that I wouldn’t mind taking, although I hate to pay so much for supplements.
