I am using this in conjunction with Lipo Hack fat burner during the day. This definitely helps you fall asleep and get that much needed rest. I have been using the combination of these fat burners for 1 week now and I am down 5 pounds.I workout 6 days a week and was at 164.8 when I started. I am now at 159.4. So the combination seems to be working since I had been holding pretty steady at 163-164 before.
