I know people who spend $30,000 on stem cell therapy. 

Did you know your body can do this for free? I'm doing it right now!

You're looking at an ice bath photo.

But I'm not talking about cold exposure today.

I'm talking about something FAR more powerful for regeneration.

Something that costs $0.

Let me explain.

I know people that pay $30,000 for stem cell injections. 

It's even available in Europe.

But in 2014, Dr. Valter Longo at USC discovered something remarkable:

Your body already knows how to regenerate stem cells.

You just have to give it the right signal.

𝗧𝗵𝗮𝘁 𝘀𝗶𝗴𝗻𝗮𝗹? 

Prolonged fasting.

Here's the science:

- When you fast for 3-5 days, your IGF-1 plummets. 
- This inhibits PKA, an enzyme that normally keeps stem cells dormant.
- With PKA suppressed, your stem cells wake up.
- They start regenerating.
- Old, damaged immune cells get cleared out.
- New ones take their place.

The data is compelling:
→ Stem cells increase approximately 6-fold 
→ Biological age reduced by 2.5 years (after 3 cycles) 
→ Immune system literally rebuilds itself

The magic happens AFTER the 72-hour mark. 

That's when your body completes the metabolic switch.

And when you start eating again? 

That's when stem cells EXPLODE with proliferation.

Fasting might be the most underrated regeneration tool you have.

And it's completely free.

I'm on day 3 right now and will be finished by Saturday :)

Do you want to try this instead of spending $30,000 on stem cell therapy?

I have created a 5-day fasting guide with special electrolytes, pre- and refeeding cycles, etc.

This is also the guide I use for my clients.

Write a comment and I'll send you the guide via DM.

Longevity for Elite CEOs | Perform, Feel & Look 15 years younger | Ex-Tech Executive | Angel Investor

You are tired. You know that you need to improve your sleep.

But most sleep advice is garbage. Here's what works.

The problem isn't that you don't value sleep.

It's that you haven't made it your identity.

Here's my mindset shift that changed everything:

I stopped being "someone who sleeps when possible."

I became a professional sleeper!

And my performance exploded.

The Protocol:

→ Schedule sleep like your most critical meeting
No "just this once." 
It's a sacred time.

→ Set TWO alarms (not for waking up)
9 PM: Wind-down begins 
10 PM: Lights out
That hour is non-negotiable transition time.

→ Replace scrolling with reading 30 minutes before bed. 
Your mind needs decompression, not dopamine hits.

→ Create a sleep sanctuary 
Blackout curtains Cool temp (65-68°F / 18-21 Celsius) 
Complete darkness 
White noise if needed

→ Cut caffeine at noon 
Not because you can't fall asleep. 
Because your DEEP sleep gets destroyed.

My results after 90 days:
- Sharper decision-making in high-pressure moments 
- Better emotional regulation with my team 
- Consistent energy from 6 AM to 6 PM 
- HRV improved by 23 points

Sleep isn't recovery.

It's your performance and longevity enhancer.

The best CEOs and executives I know treat it that way.

What's stopping you from becoming a professional sleeper?

Hey friends 👋 I spent the past few weeks soaking up some sun.
