Did I understand how thin-blood alchemy distilation methods work right?

Long ago, I prepared a Vampire the Masquerade 5e and ask a lot of questions about thin-blood. After a short time, my players decide to play non thin-blood characters. Now, I want to play a campaign with only thin-blood characters.

Thin-blood alchemy have three distilation methods. Athanor corporis, Calcinatio and Fixatio. I understand them in a way that look strange for me (mostly Athanor corporis and Calcinatio):

  • Athanor corporis: You make your formulas with your own body, and you can keep them indefinitely. But you can use only one at a time, and you have to concentrate for 3 turn to switch formulas. But something that I don’t understand is "does you keep the previous formula in your body, and just have to switch to have it again, or did you need to re-distill it later to have it again?"
  • Calcinatio: You make your formulas with kine. They have the formula in them until they have an emotional shift. If you drink there blood, you have the power. But what I don’t understand is "Is the formula is still in the human after drinking?" and "What happend if someone else drink the formula?"
  • Fixatio: Classic rpg alchemy. You make a potion, it give you powers for a short time if you drink it. The only question that I have is "can you share your formula with another thin-blood, so they can use the power too?"
