Most secret chems shouldn't be secret.

I don't know chemistry well, and probably never will. I don't think there's anything wrong with mechanics that requires multiple rounds to figure out either.

The only thing I don't like about the secrecy is it requires players to self govern, and can easily be broken by someone sharing the secrets, like when the code was stolen

I think a system that was semi random and required a bit of testing each round would be better, but I don't feel particularly strong about it
