    @boneGPT my system was ~$100,000 and is in my garage making it very easy to do it daily. Also, the 21% oxygen in the chamber allowed me to work during the session. I'm guessing many more health clinics will be getting systems like I have making it easier for you to do it close to home.

    @slotkinjr I'm similarly curious. Current plan is to follow up the 60 initial sessions with 20 sessions every 90 days however there is limited evidence to support this is the ideal protocol. We will continue to measure and assess.

    + 2 ATA
    + 90 minute sessions
    + 20 min breathing 100% oxygen. 5 min break. Repeat.
    + 60 sessions within 90 days.

    The protocol is consistent with the most credible clinical studies up to date.

    Dramatic improvements in my microbiome:

    + Akkermansia muciniphila increased by 1,000%.
    Pre-HBOT: Not detectable → Post-HBOT: 4.2E4 CFU/g

    Akkermansia is linked to gut barrier integrity and metabolic health.

    Note, I started Akkermansia on August 9th and two…
