Add tryptophan synthenase

[CatBalls]

And what effects do you propose it to have?

I could see consuming massive amounts of certain foods leading to some side-effects, much like real life. Besides high doses, what would it do at normal concentrations? I mean, are we talking Tryptophan to 5-HTP to Serotonin?

Converts to serotonin if you are wearing the burberry hat and holding the glowstick. You rub yourself against anyone who comes within one square of you.

Scratch that, they should just make MDMA a thing.
