The most I've ever done was 14 grams and that was insane. Complete out of body experience for a couple hours and an almost DMT like experience overall.

Also did 8 grams once and met a mushroom entity although it is lost to memory for the most part.

Higher dose mushroom trips are definitely a lot to handle and take a lot of preparation beforehand, going beyond the 10 gram threshold you're definitely in for a ride.

Personally though if I do mushrooms I like to stick in the 5 gram range, that's plenty for me, any lower than that and it feels completely underwhelming even with lemon tek. Any more than 7 grams it feels kinda overboard imo. You can go to some amazing places doing 5 grams in total darkness like McKenna says.
