I initially purchased a bottle of "Perfect Amino" and was pleased with the supplement. Therefore, I purchased 6 more bottles. I noticed two things, first, the company had changed the name of the product. This was not a problem. Second, I noticed a different odor coming from the product when i opened it which was not like the original. I decided it might be OK and began taking the product. The taste of the caplets was unpleasant. After a few days I noticed a change in the odor and consistency of my stools. I stopped taking the product for a few weeks, then started again. Same result. Therefore, I have ceased taking the supplement.
