Beginner ?

I want to get into psychedelics im going to take either lsd or shrooms with my brother since we both have experience being super high on edibles im thinking that we would be okay with 3.5 grams of mushrooms for the first time , the worst that can happen is a bad trip anyway (not underestimating the bad trip , but it won’t kill us either ) , what would be a good lsd dosage for starting , don’t want to trip balls but still want to have an interesting experience .
