I have been taking glp3 for a few months and I've been losing about 38 close to 40 lb. I feel great. Lots of energy. I definitely recommend iron. It's to me the most trusted legit company customer service It's amazing. They always have discounts. They always have promotions so if you want to see results go with IRON that's for sure
