What sort of poop do they prefer? I mean here the raw physical consistency, and do you prepare yourself to donate this specific kind? Or do they just take any old shit you give them? This is very interesting to me, thanks for answering questions.
I don't donate for OpenBiome so I don't know about their process, but for me they take my normal stool. I don't change my diet (you can see my other comment for that reasoning). As for preparation, there isn't much that changes from what I give them and what the patient takes (we mostly do pills). They want it as close to my flora as possible.
