Reading the site, it's interesting, but there are too many unknowns for me to get excited. Dosing, storage, pricing, delivery, effects, side effects all still seem unknown or not well understood.
Getting directly mailed a bag a poop after paying someone through zelle is a pretty wild thought.
Maybe FMT is a good idea, but it's still too unknown for me to accept it.
Regarding regulation, potentially it could follow the path of supplements which seems to be immune from the FDA, FDA doesn't regulate multivitamins nor yogurt.
Also explaining eating ass to the FDA in a formal letter is hilarious
