Anyone use "Ketone IQ" or other Ketone supplements? Or Sendure-X? What are your thoughts?

Hi all,

I have been reading about supplemental Ketones for energy and endurance performance.

Example here:   ketone.com/products/ketone

Checking to see if anyone here has used this product or similar Ketone supplements, and have any feedback on them?

Also, anyone use "Sendure-X" by PhysiVantage, and any thoughts on this product?
