Highest recorded dose of mescaline?

What's the most you guys have taken at once and what was it like? Or what is the most you've heard of someone taking? I took 400mg sulfate, and then another 400mg 8 hours later and it was a rough 2 days lol, had a couple out of body experiences and experienced what people call "the cosmic joke" wich was a little overwhelming, also felt an entity presence wich I mated with and had the best orgasmic feeling ever lol.
