You have just thrown back good advice from two of the most knowledgeable people on this forum, one of those people being a professional in this field.

You obviously are going to buy these pills regardless of what anyone says. Even when, someone who tried them (Alta818) said they don't work, and had negative side effects (speeding up your heart rate with drugs is so dangerous) you then move onto ask which ones should you buy? Common. I find it interesting that you say you would take speed to lose weight.

Even if these pills do work for you, what do you think will happen when you stop taking them? Yup you will gain the weight back.

I don't think you actually want advice, you just want someone to justify this pill for you. If you wanted advice you would have listened to the advice given, not attacked every effort to help you that is not inline with what you intend to do.
