Taking both Incarnate (Palo Alto) and a sample of SuperCissus RX (USP Labs) right now. I really like the Supercissus, but I'm not noticing much (at least Cissus wise) from the Incarnate. My endurance has gotten slightly better, but I think that's more to the Beta-Alanine than anything. But, like I said, I really like the USP Labs Supercissus.
