Just fucking with you. It would be difficult to answer your question without knowing how big a batch you want and your tolerance level. I don't do edibles anymore but used to go with an eighth per stick of butter in the recipe. Got me pretty baked and some folks too baked. Good luck!
14 grams for 4 sticks should do just fine, more if you want a stronger batch, I use to get 10 retail on those squares, use cocunut oil instead of butter
