I know “Prime” itself won’t go away, as that is the threshold mutation. I’m hoping the post threshold ones won’t, and I can then just purify away everything else.
My ideal plan would be to play mad geneticist until I’m left with Homo Superior. Get rid of weakening and rapid metabolism using purifier serum, leaving behind Prime Str, Dex, Int, Per. Then use medical serum and purifier serum until I have only the positive pre-threshold traits from that mutation path that I want as well.
If I can get enough ingredients and once I have some NPC’s who trust me, I’ll try it on them as well. Make some superhuman minions.
