How to start Acid Lab in GTA

To start the Acid Lab in GTA Online, you need to finish the six First Dose missions, then complete the setup mission to steal the equipment and install the lab in the Brickade 6x6 at The Freakshop. After that, speak to Mutt to pay the setup fee and begin running the business.

After setup

Once it is installed, you can run the business by requesting or stealing supplies and selling product later. The Equipment Upgrade is unlocked after completing 10 Fooligan Jobs, which you start by calling Dax.

Useful note

You do not need the Last Dose missions to unlock the Acid Lab itself, according to the sources above. The Last Dose missions are separate story content and are not required for the basic unlock path.
