Plus he has the lab. He could at least attempt to come up with a retromutagen, just so he's trying.

Because like last time, unless Baxter wants to move out of the city, Rahzar can just smell him out like last time and Tiger Claw's superior senses can also aid in this.

That, and Shredder threatened Baxter that his final time of disobeying him will lead to a dire consequence and for Stockman, it's not worth the risk if he gets found out again. He also doesn't trust anybody so even if he does create Retro-Mutagen, he still can't trust the Foot to spare their life just to cure Shredder's mutant henchman. He has to do what they say or he's going to get killed off regardless of making the Retro-Mutagen.
