I have tried these drops. They taste like rubbing alcohol. Most importantly, taking drops of any kind will not magically make you lose weight unless they are drops of cocaine or meth. This isn't that. So big secret to losing weight? Good diet (vegetables and lean meats), and do low impact exercise. Walking, or try P90, you will lose a ton of weight, but these drops are as effective as drops of salad dressing. Seriously, start small and get big. Also, nothing in life worth having is easy! Research low carb diets, that is what's making you fat! Sugar and simple carbs. Get rid of them and your body will burn your reserves.
Bottom Line: No, I would not recommend this to a friend
