I've been searching for a high quality stool donor for close to a decade. I'm the creator of https://humanmicrobiome.info and founder of humanmicrobes.org. I have done FMTs from more than a dozen donors. After screening 25,000+ applicants, this was the best donor I found.
I had IBS-C for many years, then took Rifaximin and it changed to IBS-D, along with many new problems, including intolerance to fat & protein. Out of all the donors I used, this one was the only one that enabled me to eat protein again.
Bad and frequent gas went away. Odor of gas & stools was drastically reduced and much less foul. Stool size decreased. Food tolerances increased.
I continued to see more & new benefits months after stopping the FMTs.
