While you've got to appreciate a guy suffering 10+ painful finger pokes each day, there are fundamental flaws with the design of this "experiment" which, unfortunately, render it valueless. For instance, no conclusions may be drawn for ANY medication, supplement, nutraceutical, etc while operating in an environment of heavy androgen supplementation. No mention of same is rendered in the accompanying text.
At this time I have quit recommending supplementation with ALA (racemic or otherwise) following evidence that it may actually be as oxidative as anti-oxidative (which Nandi has found, and pointed out for us).
