Additionally struggling with chronic mild irritation, elevated anxiety manifested in hair-twisting habits, and persistent mild neutropenia alongside recurring skin rashes, he has already stopped past heavy partying and alcohol use and is actively managing his health through an extensive supplement regimen, 40 Hz light/sound therapy, and vagus nerve stimulation.

Q

Responding to Defying dire destiny: born dead, breaking world records & thriving despite cerebral palsy 🎙️ with Mikael Avatar

I was initially going to skip this podcast because I didn’t think it had anything to do with biohacking, but this truly fits the definition. The intro is excellent and I literally had to pull over from driving and delve into this. I haven’t looked to see if there’s a transcript but if not, I’ll generate one and it will be something that I reflect back on and share often. Very meaningful and life-changing which is the essence of biohacking. Thank you.

A

Not sure if I’m going to start adding transcripts -- is that something that more of my audience would like?

Q

Jonathan, random question: I see you swaying side to side in your videos: do you have restless leg syndrome by chance? Or perhaps just have excessive energy during peak energy parts of the day?I sometimes do the bobbing knee when sitting, and sometimes when having insomnia, I find that if I shake my legs it helps my muscles to relax, so perhaps I have it somewhat myself.

A

Recommndations

Sitting is the new smoking, so I have long used an adjustable laptop stand - the poor man’s standing desk.

Do Soleus Push-Ups

Q

I vaguely recall from the years when i was more nootropics obsessed that some biohackers had started to consider racetam nootropics as having some higher risks/more moderate side effects, and thought folks were more moving away from them? Am I mistaken in this?

A

Racetams are one of the safest classes of Nootropics. Consider the safety evidence for the Racetam-rich stack I created, Caballo.

Q

Picture two identical twins over the next decade: twin A takes the absolute gold-standard nootropic stack every morning but lives in total behavioral chaos, while twin B takes sugar placebo pills but maintains absolute stoic discipline and laser focus. Who wins in the long term ??????

A

The one taking the placebo, of course! Might this hypothetical question be referring to the fictional Biohacker twins in my novel series Hourglass?

Q

A subscriber forwarded an email from David Tomen (Nootropics Expert) warning about a 2021 Seoul National University Hospital study where +100,000 Alpha-GPC users aged 50+ showed a 46% higher relative stroke risk compared to over 11 million non-users—with the risk increasing in a dose-dependent manner among those taking it daily for up to 10 years—leading Tomen to label it one of the “most dangerous supplements.” Will Alpha GPC KILL biohackers?

A

Association of L-α Glycerylphosphorylcholine With Subsequent Stroke Risk After 10 Years - The study highlights that long-term, high-dose Alpha-GPC use in elderly populations with existing vascular vulnerabilities carries potential cardiovascular trade-offs. However, claiming it is “one of the most dangerous supplements on the market” for a healthy adult using moderate doses is classic headline alarmism.

Recommndations

CDP Choline (Citicoline) - Alpha GPC alternatives like Citicoline follow a different metabolic pathway and generally do not raise TMAO levels to the same degree.

Q

What manner of bodily rite or daily custom, seeming on the scroll as dry and unlovely as a plunge into icy
