I wanna know if you can GTB with Tylenol if that could work? Or if there's better methods
A quick search told me it causes serious liver damage.
I don't think this is a reliable method. If you attempt and fail, you'll probably be much worse off than you started out with.
You could maybe end up in a state where you can't even attempt to CTB anymore.
I recommend against this method.
EDIT: If you get access to the forum's search function later, you can search for "tylenol" and you'll find other similar threads here.
The opinion on it seems to be mostly negative.
