If you’re trying to figure out which BO7 energy or milk promotion applies to your region, the answer comes down to where the promotion was offered. Both campaigns were region-specific, and their code-registration periods have now ended.
BO7 Muller Milk vs Monster Energy Codes
Both the BO7 Muller Milk vs Monster Energy Codes promotions have stopped accepting new code registrations.
The Monster Energy campaign was limited to the US, Washington, D.C., and Puerto Rico, while the Muller Milk promotion was tied to participating retailers in Germany. However, if you already claimed Muller Milk 2WXP tokens, you can still use those tokens.
The two promotions were regionally separate, so a code from one campaign could not simply be used in the other campaign’s market.
Muller Milk was the European/German option, while Monster Energy was the North American promotion for eligible customers in the US, D.C., and Puerto Rico.
Where Each Promotion Was Actually Available
Mullermilch was available in Germany and nearby European markets, while Monster Energy was limited to the 50 US states, Washington, D.C., and Puerto Rico. Both promotions required participants to be 18+ and meet their respective residency rules.
This regional split is key: US players could not redeem Muller Milk codes, and German players could not use Monster Energy codes.
The campaigns had separate codes and redemption systems. Looking for the BO7 Muller Milk rewards? Check the available Muller Milk BO7 option to see what’s included.
Current Status: What’s Still Redeemable Right Now
Neither promotion accepts new codes anymore. All official registration windows have closed, and the ability to submit new bottle caps or tab codes for Call of Duty rewards ended earlier this year.
If you have already redeemed your codes and linked your accounts, your previously claimed cosmetic items and Double XP (2XP) tokens remain permanently attached to your Activision account.
There is, however, one critical exception for active players holding unspent Muller Milk tokens. Get BO7 Monster Energy rewards for exclusive Call of Duty cosmetics and bonuses at MitchCactus now!
Current Promotion Status Comparison
| Feature | Monster Energy | Muller Milk |
|---|---|---|
| Region | US, Washington, D.C., & Puerto Rico | Germany |
| Registration Window | Sept 1, 2025 – Mar 31, 2026 | Oct 1, 2025 – Dec 31, 2025 |
| Code Redemption Deadline | April 30, 2026 | August 31, 2026 |
| Current Status | Expired: No further action possible | Active (Token Spending Only) |
If you previously registered a Muller Milk bottle code and successfully converted it into an in-game 2WXP token, you must spend it before the final system cutoff.
You can continue to activate your accumulated 2WXP (up to a maximum of 40 hours total) until August 31, 2026. You are restricted to redeeming a maximum of 1 hour of 2WXP per day.
If you have banked more than 20 hours, ensure you log in daily between now and August 31 to exhaust your remaining balance, as any unspent tokens will expire immediately after this date.
How Redemption Worked for Each Promo
Both promotions followed the same basic two-step model: enter the retail code on the promo portal, then redeem the separate Call of Duty/Activision token. However, their portals and reward tracks were different.
- Mullermilch: Four-tier reward track featuring an Operator skin, weapon charm, calling card, emblem, plus bonus 2XP. See the full Mullermilch BO7 guide for all the details.
- Monster Energy: Five-tier reward track featuring a decal, weapon blueprint, Operator skin, second weapon blueprint, second Operator skin, plus bonus 2XP. Check out the full Monster Energy BO7 guide, so you don’t miss out on anything.
Can You Still Get These Codes From Resellers?
Yes, third-party marketplaces may still list both BO7 code sets, but a bottle purchased today cannot generate a new Muller Milk code.
Muller Milk registration is closed; only a code that was registered before the December 31, 2025 cutoff could have been converted into a usable token. Before buying a reseller code, verify:
- Verify the code stage before buying: Always confirm whether the seller is offering an unregistered retail code or an already-converted token. Unregistered bottle cap codes can no longer be redeemed on the promo portal.
- Confirm the platform: make sure the code matches your intended platform and account.
- Check the region: Muller Milk and Monster Energy codes were region-specific.
- Never share Activision login credentials: legitimate code redemption should not require your password.
For Muller Milk specifically, an old code that was already registered and converted to a token may still have value, but a fresh, unregistered bottle code cannot be registered now.
