I highly recommend these drops. Particularly because they have the b12 in it. So you don't have to take a an extra suppliment. I lost 25 pounds in 30 days, 2 yrs ago and kept it off. now just lost 14 more pounds. The draw back is there is no instructions for the product so you already have to know about HCG drops. For those who dont, you take 10 drops 3x day 15 min before a meal. Also have to take 2 magnesium potassium , and 2 multi vitamin s daily. Go online to see what to eat . its a strict diet. But it works.
