[W2🌍] +1 Muscle Evolution Codes

The current public source set supports two live codes and two expired starter codes. This page keeps each reward tied to a checked date and avoids inventing codes that only appear in low-trust reposts.

Live status

Publicly verified code list

A code stays listed only when a public source still exposes it. The current pass used Roblox Den as the direct tracker and a same-day Sportskeeda rebirth guide as a cross-check for the two live rewards.

Redeem flow

How to redeem codes safely

Use the live Roblox game, clear any menu tutorial, then look for a Codes, Rewards, Shop, or Settings panel before assuming a code is broken.

  1. 1. Open the official Roblox experience for +1 Muscle Evolution.
  2. 2. Finish any first-load tutorial gate that hides the interface.
  3. 3. Open the menu that labels Codes, Rewards, Shop, or Settings.
  4. 4. Paste the code exactly as listed and claim the reward.
Why status changes

Why a code can stop working

The official Roblox metadata now shows the game title as [6H] +1 Muscle Evolution and an update timestamp on 2026-08-07, so older milestone codes can expire after fresh patches or visibility spikes.

Try the live codes first: 3KLIKES for 350 Wins and FREEPET for one pet.

If an older starter code fails, treat the expired status as more trustworthy than copied social reposts.

Check the updates page after each patch because new worlds, rebirth changes, and pet drops often arrive alongside code changes.
