Peroxide codes give you free Product Essence, and some add a free slot, in the Bleach-inspired Roblox fighting game from the [Peroxide] group. Product Essence is the currency you spend on cosmetics and on Kisuke's rerolls, so codes are the cheapest way to test different clans early. The catch is that Peroxide drops codes for likes milestones, maintenance apologies and holidays, then quietly kills them, which is why tracker lists online disagree. This page only calls a code active when the trackers that actually prune their lists agree.
Quick answer (checked October 28, 2026): there are 2 Peroxide codes that every tracker we checked lists as working: 445kLikesDupersGoAway (15 Product Essence + 1 slot) and StayHydrated (15 Product Essence). 2 more are disputed: Midnyte100kChuds and JesterMiniUpdate. Some trackers list them as working and others have already expired them, so try them after the first two. You must finish the tutorial first. Then click the bar-graph icon at the top left, open the Settings tab, type the code into the Code Here box and press Enter. Codes are case-sensitive.

What are the active Peroxide codes?
| Code | Reward | Status (Oct 28, 2026) |
|---|---|---|
| 445kLikesDupersGoAway | 15 Product Essence + 1 Slot | ✅ Active (all 6 trackers) |
| StayHydrated | 15 Product Essence | ✅ Active (all 6 trackers) |
| Midnyte100kChuds | 25 Product Essence (Pocket Tactics: 15) | ⚠️ Disputed, try it |
| JesterMiniUpdate | 40 Product Essence (+1 Slot on some lists) | ⚠️ Disputed, try it |
How we verified them: the official Roblox page doesn't list codes, and the in-game code box itself says "(You can find codes in our Discord)". So we cross-checked six trackers on October 28, 2026:
- 445kLikesDupersGoAway and StayHydrated are listed as working on Roblox Den, Bloxodes (checked October 28), Pocket Tactics (October 27), Destructoid (October 26), Pocket Gamer (October 24) and Beebom (October 1). None of them has expired either code.
- Midnyte100kChuds isn't brand new: Bloxodes first recorded it on September 11, 2026, before StayHydrated (September 21) and 445kLikesDupersGoAway (September 29). Roblox Den and Bloxodes list it as active for 25 Product Essence, and Pocket Tactics added it to its working list as "new" on October 27 for 15. But Pocket Gamer already lists it as expired, and Pocket Tactics also has it in its own expired list. That's a real conflict, so it's worth one try.
- JesterMiniUpdate is listed as working on Destructoid, Pocket Gamer and Bloxodes (40 Product Essence, plus 1 slot on Bloxodes and Roblox Den). Pocket Tactics and Beebom have expired it, and Roblox Den marks it as unconfirmed.
- DelayedMaintenanceEvilTesters is still shown as active on Bloxodes only. Pocket Tactics, Destructoid and Beebom have expired it, so we've moved it to the expired list.
This is source verification. We haven't redeemed these codes on our own account. If a disputed code does nothing after you've pasted it exactly and you haven't used it before, it has most likely expired.
How do you redeem Peroxide codes?
Older in-game screenshot (2023 build): Peroxide, captured by Destructoid. The menu path is the same one current trackers describe.
- Launch Peroxide and finish the tutorial. The Settings tab stays locked until you do.
- Click the bar-graph (stats) icon in the row of buttons at the top left of the screen.
- Open the Settings tab. It's the last of the four tabs: Stats, Party, Reputations, Settings.
- Click the Code Here box on the right side of the panel and paste a code.
- Press Enter on your keyboard. There's no submit button, and the Product Essence is added straight away.
Bloxodes sums up the only requirement: "There are no level or progress restrictions to redeem codes, but you must finish the tutorial to access the settings menu." Don't use the Roblox website's promo-code page. It only takes Roblox promo codes, not in-game ones.
Why is my Peroxide code not working?
- It has expired. This is the usual reason. Peroxide retires codes without warning, and some sites keep dead codes "working" for months.
- Wrong capitals. Codes are case-sensitive. 445kLikesDupersGoAway needs the lowercase "k" and the capital "L", so paste it rather than typing it.
- You haven't finished the tutorial. You can't reach the Settings tab before that.
- You already used it. Each code works once per account.
- You typed it in the wrong place. Use the Code Here box in Settings, not the Roblox website.
What are the expired Peroxide codes?
Peroxide has retired over 270 codes since it launched in 2022, according to Bloxodes' count. These are the recent ones, all listed as expired by at least two of Pocket Tactics, Pocket Gamer, Destructoid, Beebom and Roblox Den:
| Code type | Expired codes |

Don't mix up 445kLikesDupersGoAway (active) with 445kLikesYipee (expired). They're for the same milestone, and only the first one still works.

Is Peroxide still popular in October 2026?
Yes. Our Roblox Games API pull at 16:07 UTC on October 28, 2026 showed 1,671 players online, 423.2 million visits and 871,062 favourites. The like ratio is 90.9% (458,195 up, 46,069 down). Roblox lists the experience as created on March 14, 2022 and last updated on October 28, 2026, and it's currently titled "Peroxide [Update!]".
Destructoid warns that Peroxide doesn't have "a nice, friendly learning curve". The official description calls it "an anime stylized fighting game in which players fight monsters to get stronger, as well as partake in hard trials to gain new abilities". That's why Product Essence matters: Pocket Gamer notes you can spend it on cosmetics "or give them to Kisuke and gain rerolls, which are much more valuable". If you're new, save your codes' Essence for rerolls rather than dyes.
How do you get more Peroxide codes?
Peroxide codes follow clear patterns. Most are likes milestones, and the name tracks the count: 440kLikes, 445kLikesYipee and now 445kLikesDupersGoAway. The others are holidays (4thJuly2026, ValentinesDay), maintenance or outage apologies (DelayedMaintenanceEvilTesters, Serveroutage925) and update codes (JesterMiniUpdate). Nobody knows a new code until the developer posts it, so ignore any "leaked" or "secret" lists. These are the official channels to watch:
- The official Peroxide Discord (discord.com/invite/Peroxide): the in-game code box points here, and codes go out in the announcements channel.
- The Peroxide Trello board: not a code feed, but the best reference for clans, moves and items.
- The Peroxide Roblox group: 297,431 members on October 28, 2026.
Peroxide had Halloween codes in 2024 and 2025 (HappyHalloween24, PeroxideHolloween2025), so a 2026 Halloween code is possible. We re-check this page regularly.
