Also, he could be trying to create his own version that doesn't require April's DNA!

Plus, if he did try to replicate Donnie's version, it would need April's DNA, and that would mean that the only human DNA retromutagen needs is April's, and he doesn't even know that Donnie's version requires that. Therefore the substance isn't human DNA, it's his own prototype version of retromutagen!

BTW, Karai is not half-human, she is a mutant serpent!
