Codes checked: 2 October 2026 · Game last updated by the developer: 2 October 2026
Looking for peroxide codes? Every code that still works in Peroxide, the Bleach-inspired fighting RPG, is listed below, followed by the long list of codes that have already expired.
Almost every code pays out in Product Essence, the currency behind rerolls, and the best ones add a character slot so you can keep a second build without deleting the first. Codes here carry real expiry dates rather than quietly dying, so claim them while they are up.
All Working Peroxide Codes
- 445kLikesDupersGoAway: 15 Product Essence and 1 character slot
- StayHydrated: 15 Product Essence
- JesterMiniUpdate: 40 Product Essence and 1 character slot
Capital letters matter here more than in most Roblox games, because the codes are written as sentences rather than shouted. Copy them rather than typing them out.

How to Redeem Peroxide Codes
- Launch Peroxide on Roblox and finish the tutorial, which is what unlocks the settings menu.
- Click the Settings icon in the top-left corner of the screen.
- Open the Settings tab and find the Code Here text box.
- Paste a code into the box and press Enter to claim it.
If the settings icon is missing, you have not finished the tutorial yet. There is no way to redeem a code before that point.
What Product Essence and Extra Slots Are For
Product Essence is the reroll currency. You spend it on the abilities and modes that decide what your character can actually do, so a code worth 15 or 40 of it saves a long stretch of passive farming.
Character slots are the rarer reward and the reason the like-milestone codes are worth watching for. An extra slot means a second build, usually one Soul Reaper and one Hollow, without wiping the character you already levelled.
Premium players earn double passive essence in the AFK world, so a slot code is worth more to someone already farming there than the raw essence codes are.
What Is Peroxide?
Peroxide is a Roblox fighting RPG styled after the Shonen series Bleach. You fight monsters to get stronger and run hard trials to unlock new abilities, with dashes, modes, weapon draws and a spirit realm for rebinding skills.
It was built by the Peroxide team and first opened on 14 March 2022, which makes it one of the older games still getting updates. As of 2 October 2026 it had 419.2 million visits and 864.6 thousand favorites, with around 1.6 thousand players in game at once and an update shipped the same week.
Where to Find New Peroxide Codes
The developers post codes in the official Peroxide Discord, usually attached to a like milestone or a patch, and they rarely announce them anywhere else first.
The naming pattern is the giveaway. Most codes are either a like count, such as the 445,000 one on the working list, or the name of the update they shipped with. Expect the next one at the next round-numbered like total.

Frequently Asked Questions
How many Peroxide codes are working right now?
Two, as checked on 2 October 2026. Peroxide runs a short working list on purpose, because its codes carry fixed expiry dates rather than sitting live indefinitely.
When do the current Peroxide codes expire?
The current codes are dated to run out on 18 and 26 October 2026. Claim them well before then, because the game gives no warning when one lapses.
What is Product Essence used for in Peroxide?
Rerolling abilities and modes. It is the currency that decides how quickly you can shape a build, which is why nearly every code pays out in it.
Why is my Peroxide code not working?
Check the capital letters first, since these codes mix cases in the middle of words. If the spelling is right, the code has passed its expiry date, and expired codes in Peroxide stay dead.
