Query: I can't tell if these work or not

I've used an entire bottle of the CLA and I don't know if they actually work. I definitely haven't lost weight, but haven't really gained much either. Who knows if these are keeping me from doing either. I have another bottle I am using, but I dont think I will continue after that bottle is gone because of the unknown results.I cannot say I recommend these, nor would I recommend to a friend.
