Ah my peanut butter, yeah I do it with TFA in 24 mg 50/50 PG/VG (don't go below 40 VG, it need the viscosity to get the right mouth feel and not let the bitter notes in that flavoring linger too long on the tongue.) then add 2% Sweet Cream or Vanilla Cream, Madagascar vanilla, or Vanilla Bean if that's all you have and, 0.5% Sucralose for a not very sweet, 1.5 to 2% for a peanut butter cookie sweetness. Let it breathe 3 hours, cap and steep in a warm, dark place for 72 hours.
It is good, too good - just put the PV down before you get nic dizzy.
