Bests & Worsts Reviews from Amazon

I am confused. I bought this product before and and took 2 capsules a day for 30 days. Amazingly, my blood sugar dropped into the normal range. My doctor can reacted, "what on earth did you do?" On Amazon be I hit the, "Buy this again" button. The bottle that arrived was larger than the first but the labeling was identicle. The capsules were also larger and a different color. These were dark brown and the first capsules were a couple light tan.. The new tablets do nothing for my blood sugar or anything else. I tried a different brand and those pills were identicle to the last pills. They didn't do anything either.
