While appearing on ThisIs50, Mr. Porter talked about Eminem’s new REVIVAL track and confirmed that there was another version of “Cloraseptic” that featured 2 Chainz and Phresher.
According to Porter, they brought in 2 Chainz to do the track but also ended up recording a verse as well. However, Eminem only wanted 2 Chainz for the hook but the hook didn’t sound that good when they recorded it, so they replaced him with Phresher instead.
The reason 2 Chainz verse never made it to the album was because Eminem was already set on his ways with how he wanted the track to sound and didn’t want to change his vision.
