Sorry to hear this batch didn't meet expectations. Looking at your order history, you've purchased from before without issue, so we take it seriously when a repeat customer has a bad experience and we're glad to hear the MOTs-C from the same shipment is performing well for you. Every lot we ship is third-party tested, and we're happy to post or send the COA for the specific lot you received. Reach out with your order number and we'll make it right. Being a small business reviews impact us in a large way being a 1 star or a 5 star but the biggest is making the experience better for you.
