Episode overview

Ben Greenfield: What Biohackers Get Wrong & What ACTUALLY Works!

The Bossticks · 21 September 2026 · 1h 21m · 2 Egleze moments

What happened in this episode?

Ben Greenfield tells The Bossticks he has become less convinced that ever-more elaborate biohacking delivers fulfilment, arguing his priorities shifted after nearly losing his marriage and family around 11 years ago. He describes building daily routines around family connection—morning ‘huddles’ and nightly dinners—while still experimenting with health interventions as what he calls an ‘immersive journalist’.

On the more extreme end of biohacking, Greenfield says he has tried blood filtration procedures, including travelling to Mexico for catheter-based ‘full body blood filtration’, and portrays plasmapheresis-style ‘oil change’ treatments as an expanding trend. He also gives a detailed account of using the GLP-1–class drug candidate retatrutide, saying he microdoses it when travelling and has stocked up from ‘grey market’ suppliers he expects to face legal pressure.

Greenfield revisits diet advice he previously championed, saying he has moved away from strict ketogenic eating for active people and now prefers a cyclic low-carb approach with a large carbohydrate meal at dinner. Elsewhere he discusses peptides, microneedling and exosome-based skincare and hair-loss interventions, and makes contentious claims about Wi‑Fi/EMF effects on the body while promoting measures such as disabling wireless devices overnight.

He also promotes a new documentary, “Boundless: The Man Who Became Human”, confirming filmmaker Caleb Applegate and executive producer Zach Efron, and saying it will stream on Amazon and Apple from 22 September.

What are the key points?

Greenfield says he underwent blood filtration procedures and claims some versions require travel to Mexico because they are not available in the US.
He says he uses retatrutide in ‘micro doses’ for travel and claims legal action will make grey-market supply harder to access.
Greenfield says he has shifted from strict keto to cyclic low carb, including 200–300 grams of carbohydrates at dinner.
He argues high GLP-1 dosing can make strength training and adequate protein intake difficult, and disputes some muscle-loss headlines.
He claims Wi‑Fi/EMF exposure increases calcium influx into cells and recommends switching devices to aeroplane mode and using Wi‑Fi timers.
He confirms a documentary about his biohacking career and values shift, naming Caleb Applegate and Zach Efron, with streaming planned from 22 September.

Health, Longevity & Biohacking

Ben Greenfield says he has tried blood-filtration ‘biohacking’ procedures, including in Mexico

Ben Greenfield · at 1:34 · Attributed speaker claim

And this whole field of like um plasma feresis, right? Pulling blood out, filtering it, putting typically something like elbumin back in, and then an IV or like full body blood filtration, which is super gnarly. Uh you can act, you can't do this in the US, but like you go to Mexico and get all the blood sucked out of your body typically via a catheter in your jugular. >> Have you done it? Uh yeah.

Ben Greenfield says he has experimented with plasmapheresis-style blood filtration, including travelling to Mexico for a version he claims is not available in the US. He describes the practice as an emerging biohacking “oil change for the body”, and says clinics in Austin now offer related catheter-based blood-filtration treatments.

Controversial

Ben Greenfield claims Wi‑Fi and other EMF exposure increases calcium influx in cells

Ben Greenfield · at 1:05:23 · Attributed speaker claim

Wi-Fi, EMF, EMF and radio frequencies >> increase calcium influx into the cell. So now you take somebody and they're in chronic stress, they have cortisol release and then they're around and you know this is like all of a sudden the tinfoil hat discussion because it's an inconvenient truth.

In a discussion about stress, “electrical” health and PEMF products, Ben Greenfield claims that Wi‑Fi, EMF and radio-frequency exposure “increase calcium influx into the cell”, and suggests this may compound the effects of chronic stress. He also argues there is “not necessarily a biological free cost” to having phones and routers on all day.
