5f adb c liquid

How much 5f adb should i put in a 5ml bottle of vg to make c liquif

First off use only pg, then add a few drops of that to a tank w reg juice, will not dissolve in chi, and I’m sorry I can’t help w dose, I’d say make a test batch maybe 1mg per ml or 2mg per ml but I have no clue about this chem so take my dosage suggestion with a grain of salt start low if your too eager to wait for a response
