My question was more towards the product than the link. Even if the link is a scam what do you think about the product. Its available on ebay and amazon and it says it doesn't have any side effects?
Forget about it, fabolous_871. Here's a comment from WebMD
Raspberry ketone became popular for weight loss after it was mentioned on the Dr. Oz television show during the segment called “Raspberry ketone: Miracle fat-burner in a bottle” in February 2012. Even though it is touted as a “miracle” for weight loss, there is no reliable scientific evidence that it works for improving weight loss. [...] Raspberry ketone is a chemical from red raspberries that is thought to help for weight loss. Some research in animals or in test tubes shows that it might increase some measures of metabolism. It might also affect a hormone in the body called adiponectin. However, it is important to keep in mind that there is no reliable scientific evidence that it improves weight loss when taken by people.
