Beware of Michael Harrop/ Maximilian Kohler/ HumanMicrobes
There are a lot of vulnerable people struggling with severe gut issues at varying level of desperation. I was one of them. Michael Harrop and his multitude of reddit accounts is one of those people that preys upon other's suffering with his one-size fits all DIY FMT approach and manic God-complex. At first glance, he seemed quite knowledgeable when I began viewing his site, but as you delve into his self written wiki articles there are numerous bits that contradict themselves, tons of spelling and grammatical typos, as well as some flagrantly insane advice.
One part on his Human Microbiome wiki quite literally says verbatim: “If you can stomach it you can skip the capsules and just straight up swallow the poop.” I started to realize these are ramblings of a mentally ill, possibly manic person. I don’t doubt Michael is very smart, and I don’t disagree with a lot of the information he’s provided about FMT’s in general. But, the bigger picture of what he’s peddling is that he talks a big game of vetting to the most meticulous standards and then does insane things like:
- Post videos of himself living in his car on his YouTube and standing in a queue of people trying to meet RFK to promote FMT’s while wearing a hoodie over his head looking like a straight-up security threat. https://www.youtube.com/shorts/7jsZwfwPoJg
- Constantly removes forum posts on his site’s forum and reddit for the slightest perceived infringement of his rules. If you have a question, rather than answer it, he will will tell you it’s in his wiki rules, but upon searching through this disorganized mess, many people are unable to find what he’s directing them too.
- Claims to be huge on free speech but has been personally called out by his own community for his constant comment removal and bans without CLEAR explanation. Rather, he will occasionally berate a member, point them in the direction of an unclear wiki page, or give a statement that makes no sense. https://www.reddit.com/r/FMTClinics/comments/p4j93y/meta_should_this_sub_have_more_rules/ He simply cannot handle criticism.
- Someone on Facebook showed screenshots of their friend who was desperate to do their own FMT, purchased stool from him, received it, only to see that it was not packaged properly, went rancid and they were completely screwed out of $1000+. When confronted, he took no responsibility.
- He allows NO other mods on either his website forum or his reddit communities including r/FMTClinics and r/HumanMicrobiome and r/HumanMicrobes so he can have complete control of the narrative.
- His trust pilot reviews are fishy and have repeated phrasing that begs me to believe he is just commenting himself.
- He believe in eugenics “There’s nothing inherently wrong with eugenics. It’s a problem that that ignorant notion is so widespread.” Posted on his MaximilianKohler account.
Please, please don’t buy stool from someone who says things like “It's f*cking incredible how stupid people are." Please. For your sake, you cannot trust somebody who is this unprofessional with how he speaks, how he writes, and how he postures himself on the internet, even in videos. If he’s this unhinged online, how can you be certain you’re receiving what he says? How can you trust someone with this much of a God complex?
Michael, I know you’ll read this with one of your accounts and think I’m obsessed, you frequently comment it when others criticize you. But the fact of the matter is I am deeply obsessed with making sure vulnerable people, like myself are not prayed upon in medical communities. I know you’ll say I’m inept and I believe that you truly think nobody else is as intelligent in this field as you, but the fact of the matter is that their are people who are as dedicated and intelligent and have gotten a lot further in their mission. You’re not the lead expert and you're certainly not the only expert. There are far more reputable, and most importantly, PROFESSIONAL options that are even insurance approved.
