Has anyone tried Endothil-CR? It's a sublingual supplement. I bought the 60 day supply, and I'm not sure if it's working as placebo or for realz. I feel an increase in stamina at least, which allows me to tear up my muscles a bit longer in the gym. If it's not placebo, I wonder if the Quercetin is doing more than the green tomato SE, as Quercetin is a vasolidator.
