Peroxide rewards players with Product Essence, Premium Dye, and extra character slots whenever the developer drops a new code. These freebies matter most early on, when resources for rerolling clan traits and abilities are scarce and the fights get tough fast.
Working Peroxide codes
Copy any of the codes below exactly as written, since Peroxide’s redemption box is case-sensitive and won’t accept typos.

How to redeem codes in Peroxide
Code redemption unlocks once you finish the opening tutorial, which walks you through the game’s core combat before dropping you into the main city.
A successful redemption immediately adds the listed Product Essence, Premium Dye, or slot to your account, visible in your inventory or character menu. If nothing changes after hitting Enter, the code has likely expired or was entered incorrectly.

Where new Peroxide codes get announced
New codes typically go live around like-count milestones, holidays, and content updates. The official Peroxide Discord server posts them first, usually in an announcements channel, so joining it is the fastest way to catch one before it expires.
Note: codes are case-sensitive and single-use per account, so copy them directly rather than retyping to avoid a wasted redemption attempt.
Product Essence earned from codes goes straight toward rerolling clan traits, Shikai and Res abilities, and other build choices, which otherwise take considerable grinding to accumulate naturally.
