NSI-189

A substance that grows brain cells in the hippocampus and effectively treats depression. It also makes you smarter. The best doses are 40mg to 80mg daily for a few weeks. Benefits last far beyond the final dose taken. It's a cognitive enhancer.

I treated my depression with NSI-189. Now I am much less depressed, and smarter.

NSI

Nsi is a pro minecraft/League of Legends/Rocket League aaaand CS:GO player.
Rumuor has that he even teached players like Faker on league but when the community needed him the most he vanished. Only if a player is at least top 5 in all the games from the above he can truly call himself as good as NSI>

1: Did you know that NSI teached faker in season 2?
2: Isn't NSI the same dude that disappeared all those years ago?
1: Yeah, such a shame
