I posted about progesterone last December. There is a problem with it as a therapy. The doctor who did the research is trying to patent it. The name you mentioned is the name of the study. This is the third study. The first to be using double blind clinical study methods. The open study has shown very good results.
There is a generic version known as bio-identical progesterone. Hopefully, the FDA will not prevent it from being used as a brain injury therapy.

There needs to be action to get the FDA to prevent the over-charging for this therapy. The FDA and Big Pharma have already tried to get bio-identical hormones outlawed. With the incidence of brain injury in this country, any attempt to over-profitize this therapy should be fought.
