Peroxide rewards players who redeem codes with Product Essence, the currency used to reroll race, clan, and appearance at Kisuke Urahara’s shop. Codes occasionally add a free character slot too, which matters once you start experimenting with different builds.

How to redeem codes in Peroxide
A successful redemption shows the Product Essence total (and any slot reward) update immediately in your stats panel. Tip: Copy each code directly from the list above instead of typing it out, since a single misspelled character or extra space will cause the code to fail.
Expired Peroxide codes
These codes no longer give rewards. Keep this list handy so you don’t waste time retyping something that already stopped working.

Where to find new Peroxide codes
New codes usually go out around likes milestones, holiday events, or after maintenance windows. The Peroxide Discord server is the fastest place to catch an announcement the moment it posts, and the official Peroxide Trello board keeps a running Codes card alongside patch notes and other game details.
Product Essence from these codes is meant to smooth over the reroll grind, not replace it entirely, so treat each one as a head start rather than a full shortcut through the game’s progression.
