Ceretropic only just announced its availability: https://www.reddit.com/r/Nootropics/comments/5h1mge/its_here... I assume this is why the sudden renewal of interest and a January article on it showing up on HN...

You've linked to the wrong reddit. That one is about a substance called P21.

Orexin is also discussed in that thread. Ceretropic announced the release of P21 and Orexin at the same time.
