I agree with Amateur's post #71168, except the stinking bid/buyout part.
We have wanted to hear how 2-73 works and though it alone was give to only 7 (max) active participants, we know that given a 6 month period, it begins to show its positive capabilities. Dr. Mac stated that the pianist, painter and golfer did not begin to show their skills until they had been on 2-73 for 8 months or more. Though not noted by him, the data I think indicates that they were taking only 2-73.
The small size hurts credibility (was it a anomaly?) but it still presents results that are fantastic. As I noted before, I hope that all have been switched to 2-73 only and, if such, a PR should be released ... in fact, a PR on the current dosing status is in order, because if they haven't been switched, it begs the question: "Why would all participants be interested in continuing through the two extensions?"
