GNC told me that using it by itself is kind of useless. there's other things you're supposed to take with it (rasberry ketone, green leaf tea, etc) and you have to follow exactly what it says or it won't work.

I've heard that it really works but like @abtayy said you have to take some sort of body cleanser for it to get the full effect. Read online about the cleansers people take with the pills

I haven't but I'm pretty sure you're supposed to take them with some sort of whole body cleanser as well for it to work. Sort of like a colon cleanser
