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.

NSISH

NSISH, which stands for Nutty Scholarly Intellectual Study Hall, is a collection of highly intelligent EPIC GAMERS who wish to have a place to cultivate their knowledge. Often paired with "uwu®", it is an extremely selective institution which takes a holistic approach to its admissions. However, it currently faces controversy over the necessary qualifications, some of which involve race.

All the kids from NSISH got 50s on the Bio test. What GODS.
