It’s a supplement you take twice a day, you can’t eat fats, oils, sugars, carbs, salts or starch. You can eat 500-1000 calories and workout only if you eat over 500 calories. The brand I use is HCG platinum X-30, at gnc for $65. I’ve lost 10 pounds in two weeks. I recommend using it in the healthy way. People will judge you for using it so be careful.
