Great on the delivery, product labeling might be a little inconsistent
I ordered two salvia extracts, one labelled as x10 potency and another as x40.
I felt the x40 was about the same potency or even weaker than the x10. I'm not sure if that an error on my part while using it, but according to other reviews of several online salvia sellers, the salvia extracts that are labelled as x10 and x20 are usually the most reliable and consistent with their labels so I was prepared for that, but still I felt a little bit disappointed with having spent more money on it and getting a weaker effect.
Other than I had no problems with the delivery and the x10 worked wonderfully. I might order a x20 extract in the future to compare it to the x10, but I am reluctant to order an x40 or higher again.
