RoM Potions for humans?

Thanks guys for your responses. I was hoping it would work as intended as at some point I’ll be boosting it with Zero’s mod for true immortality - I had hoped the immortal potion would freeze ageing entirely. As it is I’ve established a workaround using MCC to flag the individuals as immortal. The reason I haven’t just gone for the simple ‘turn off ageing’ setting is because I’m playing an RP style save with multiple supernaturals and immortals (designed as non game supernaturals like demons) so I want the adults and elders to remain frozen in age but the teens and children to gradually age to YA then freeze into immortality, while other mortal sims age and die naturally. Which could theoretically be plausible using the setting, which I’m a bit rusty on, but I’m not entirely sure. But since I think my MCC plan is working at the moment, problem kind of solved!
