I used this product too. It works much different than HCG drops. The ketone drops helped me maintain my weight after the HCG Warrior diet. I lost a bunch of weight and wanted to keep it off so I used the Raspberry Ketone Drops. I still use these drops every day and I am in the best shape of my life. My sister used Ketone Drops and lost 18 pounds over 3 months so she is a big fan. I consider myself a supplement guru considering I have been using supplements almost non stop since i was 17 Anyways, you can't go wrong with this product.. to many good ingredients in it. Enjoy!
