Muscle Transform Simulator Codes (September 2026)

Muscle Transform Simulator has you bulking up your character through repeated training sessions, and codes give you a shortcut in the form of free spins and potions that boost your gains without extra grinding.

Working Muscle Transform Simulator Codes

Here are the codes that are redeemable right now. Type them in exactly as shown, since the code box is case-sensitive.

How to redeem codes in Muscle Transform Simulator

You don’t need to leave the game or log into any website to claim these rewards. Everything happens through the settings menu once your character has loaded in.

You’ll know a code worked because your spin or potion count updates right away in your inventory. If nothing happens after you press Enter, that code has probably already been used on your account or it’s no longer active.

How to get more Muscle Transform Simulator codes

New codes tend to show up around content updates or milestones, so keeping an eye on the game’s official channels is your best bet. The developer’s Discord server is the most reliable place to catch new drops as soon as they’re announced, and you can join it directly through this Discord invite.

You can also check the game’s page on Roblox itself, where the developer sometimes leaves update notes tied to new codes. The Muscle Transform Simulator experience page is worth bookmarking if you play regularly.

Why didn’t my code work?

If your spin or potion count doesn’t change after pressing Enter, the code has either already been redeemed on your account or it’s expired. Double-check your spelling and capitalization before trying again, since the code box won’t accept partial matches.

Redeem these codes while they’re still active, since none of them come with a listed expiration date. Grab the free spins and potions now and put them toward your next training session.
