I'm 49 with 10-15 pound of tummy-fat I want to loose - I tried OTC hCG (2 btls) but it did not work - how do I get a stronger doctor prescription?

Nothing available. There is no prescription medication proven to remove tummy-fat. As always one should try weight loss through appropriate diet and exercise.
FDA no OTC HCG. The fda has made otc HCG illegal because it is unregulated. If you want to lose weight you should see a bariatrician for a medically diirected program.
