"Testosterone is a toxin" is something I've mused about being an aspect in a dystopia for a while. Monolithic habitation blocks where you rent a sleeping cubicle per use, everything is drab and neo-brutalist because your implanted HUD eyepiece projects augmented reality spam over everything. You wear an issued jumpsuit and respirator, but it's ok because you can make an augmented reality avatar that's projected over you for everyone else. You can even customize your sleeping cubicle with AR and apply those settings wherever you go! Another implant affects how you taste and smell things, so the homogenized slop everyone is given to eat can have a simulated taste per consumer. That slop is fortified with things to make you 'healthy', appetite suppressors, mood stabilizers, and testosterone inhibitors. All this is charged to a digital currency that is debited from another implant... access to which is determined by your social credit score. If you're a bad boy, you're cut off. Not from food and shelter of course, not for the minor infractions anyway. You just loose access to the AR and taster features. So you go through the world, seeing it as it really is. And your avatar settings are disabled, so everyone sees you as you really are, too. You're singled out as being abnormal, even though everyone looks and lives exactly like you do.
