Pigliatizone trial was stopped before it even started, because of lack of patients. You can write to the people doing the trial, and you will get an answer. They have another trial using another agent starting soon.
I have been taking it for 9 months now with mixed results. I feel my legs are little more flexible, but also a little weaker. I think it may take a while to have some real effects. So I keep taking it. Anybody in US who want to try it should talk to your doctor and they can prescribe it to you. Clinical trial is going to take a while (even if there is one going on). So we may want to try it ourselves to see if it is beneficial to us. Everybody's response to it may be different. I will keep updating my progress (if there is any). Good luck with everybody.
