I know how skeptical and cynical HN can be, so I thought I should add that while I've become an evangelist, it isn't me that is claiming NSI-189 as a treatment for depression and ptsd, its the maker Neuralstem, and it's backed up by autopsied rats whose hippocampus grew 20% in size after the drug was administered.

Here is an interesting blog post from the maker about NSI-189 and NZT from the movie limitless.

I think NSI is such a cool story because besides perhaps rescuing millions of people from the despair of PTSD, it is so similar to the concept of NZT in Limitless.

And just like in Limitless, it is not easy to procure at the moment.
