Peroxide Codes (September 2026)

Peroxide is a Roblox anime fighting game where codes hand you free Product Essence, the currency you’d otherwise grind for, plus the occasional character slot. Punching in a working code takes seconds and saves you real playtime, so it’s worth checking your list before you jump into a fight.

How to redeem codes in Peroxide

You won’t find a redemption page on any website for this one. Peroxide keeps its code box tucked inside the in-game settings menu, and it only shows up once you’ve made it past the tutorial and reached the main city.

Launch Peroxide on Roblox and finish the tutorial if you’re a new player, since the settings menu stays locked until you’re standing in the main city.

Click the bar graph icon sitting in the top-left corner of your screen.

Select the Settings tab from the menu that pops up.

Paste or type the code into the text box exactly as it’s written, then hit Enter. If it worked, you’ll see your Product Essence total jump right away, and any bonus character slot will show up on your character selection screen. Nothing happening after you press Enter means the code is expired or mistyped.

Expired Peroxide codes

These no longer add anything to your account, so don’t waste time typing them in.

How to get more Peroxide codes

New codes tend to land around update announcements and community like-count milestones, so keeping an eye on the developer’s own channels is your best bet. Join the official Peroxide Discord for the fastest word on fresh drops, and check the Peroxide Roblox page for announcements tied to the experience itself. We check back regularly and update this list as soon as new codes go live and old ones stop working.

Why didn’t my code work?

Peroxide codes are typed exactly as published, capital letters and all, so a single misplaced character stops the redemption cold. If the code has already expired, the game simply won’t register any change to your Product Essence total no matter how carefully you type it.

Codes like these don’t stick around forever, and Peroxide’s developer tends to retire them once a milestone or event passes. Grab what’s active now, and check back for the next batch tied to the game’s next update or like-count goal.
