Peroxide Codes (October 2026): New Halloween Code Adds Product Essence and Yen
Peroxide codes just got a seasonal addition. A new Halloween-themed code was added October 29, 2026, joining two codes that remain confirmed active across multiple trackers. The Bleach-inspired Roblox action RPG hands out Product Essence, the premium currency used to reroll your race, clan, and appearance at Kisuke Urahara’s shop, and occasionally bonus character slots.
Here’s everything active as of October 29, 2026.
Active Peroxide Codes
| Code | Reward |
|---|---|
| PeroxideHalloween2026 | 40 Product Essence, 2,000 Yen |
| 445kLikesDupersGoAway | 15 Product Essence, 1 Slot |
| StayHydrated | 15 Product Essence |
PeroxideHalloween2026 is the best pick right now, since it pairs the largest Product Essence payout of the three with some bonus Yen on top.
One more code, JesterMiniUpdate, which gives 40 Product Essence and 1 new slot, still shows up as active on some trackers, but others have marked it as expired, with one reporting an October 6 end date. It only takes a few seconds to test, so try it, but don’t be surprised by an invalid code message.
How to Redeem Peroxide Codes
- Launch Peroxide in the Roblox app and complete the opening tutorial if you haven’t already.
- Open the Settings menu.
- Find the code entry field.
- Paste your code exactly as written.
- Confirm to claim your reward.
Peroxide codes are case-sensitive and some are quite long, mixing capital and lowercase letters, so copying and pasting is far safer than typing them by hand. If a code gets rejected and you’ve double-checked the spelling, it has likely expired, since the developers can disable codes at any time without warning.
Recently Expired Peroxide Codes
Several codes from earlier in the year no longer work, including DelayedMaintenanceEvilTesters, 450KLikesWithUpdateSoon, 445kLikesYipee, 4thJuly2026, Midnyte100kChuds, TheEvilHalloweenDuper, YayAHalloweenUpdate, and PeroxideHolloween2025. Peroxide has retired more than 270 codes since launching in 2022, so older lists you might find elsewhere are almost certainly outdated.
How to Get More Peroxide Codes
The game’s official Roblox page doesn’t list codes directly, and the in-game code box itself points players to the Peroxide Discord server instead. New codes tend to arrive around likes milestones, maintenance apologies, and holidays, then get quietly retired without announcement. Checking the Discord regularly is the most reliable way to catch a new code early, and bookmarking this page works as a solid backup.
