This seems to be good quality and they build trust with the third party testing. The bottle arrives safety sealed for assurance. The blend is good; especially with the BioPerine for easier absorption. The capsules have not taste and are easy to swallow. So far, I'm quite pleased. The quality and price seems fair compared with other offerings. I have no negatives to note.
