I need to lose weight

As what I've written in my other posts,I'm planning to take a diet pill.I need to lose weight.I've already searching on the net and read some product reviews.I just want to make sure I'll take the one that is effective and safe for me to use.While browsing on the net about diet pills,I came across to a site that features liporexall.My always question is,is it safe for me to use?I know I couldn't answer that even the reviews that I read is not sufficient.I better ask my doctor first before trying any product.I don't want to put my health on risk.
