Comment from a previous thread: Another user mentioned that this should be common sense, which I agree with, and have been surprised at the amount of people arguing against it. Personally I would think it would also be common sense for the universities doing FMT studies and other microbiome...

https://www.frontiersin.org/articles/10.3389/fcimb.2019.00002/full An important paper to have submitted here. Unfortunately, the authors of this review didn't bother to attempt to find a super-donor for their FMT trial...

https://the-peel.com/article/1723/ This doesn't seem to be a real story. See their "about" page: https://the-peel.com/about/ Their bluesky says "on the mission to deliver news before it happens".

The wiki has a section on them: https://humanmicrobiome.info/where-to-get-fmt/#ippm-clinic No, I would not use them.

Extremely unlikely. This is why I've spent the past 10 years warning people about using low-quality donors, and the poor donor screening & selection at hospitals, clinical trials, and stool banks.

In general, it seems like the only way to recover from a bad FMT is to do FMT from a better donor. Where did you get the FMT? From a hospital, using their donor? They did it for IBS? Was it part of a clinical trial?

Yes, I think Fedex is the easiest option.

https://onlinelibrary.wiley.com/doi/10.1002/imt2.70083 This is incredibly depressing. Not a single mention of donor quality, and they're promoting the failed & inadequate stool bank model.

https://www.thelancet.com/journals/langas/article/PIIS2468-1253%2825%2900190-6/abstract A previous study indicated that a sterile fecal filtrate was effective for C. diff. https://humanmicrobiome.info/fmt/#sterile-fecal-filtrate This study says otherwise.

If you mean studies supporting your claim, you need to cite them. As you note, I already commented on that anecdote and debunked the claim.

Is there? I only know of one rat study that showed problems. There's a huge body of human data saying otherwise.

What criteria? https://humanmicrobiome.info/cancer/ You can see there is plenty of basis for concern that you may "transplant a biome that supports the development of cancer". It's largely unknown. FMT is all about risk vs reward, and family history is an added risk.

Did you review the probiotic guide? https://humanmicrobiome.info/probiotic-guide/ FMT would be the most effective option, but it's not going to be widely available from safe & effective donors unless people start taking action...
