Seven back surgeries. A near-traumatic amputation. And he’s still trying to compete at the Masters.
I don’t think Tiger Woods is taking these medications to get high. I think he’s taking them because he is in an excruciating amount of pain — and nobody in his circle is having the hard conversation with him.
Here’s what I see as a pain specialist:
He’s clearly tolerant and dependent on these medications. That’s not a character flaw — that’s what chronic pain does to a person over time. But tolerance and dependence mean the medications are no longer doing what they’re supposed to. They’re just keeping him functional enough to keep destroying his body.
And the dangerous part? Mixing benzodiazepines — Xanax, Klonopin, Va**um — with long-acting narcotics. That combination is how people end up in serious trouble. Fast.
Someone needs to be the adult in the room.
Not to shame him. Not to lecture him. But to look him in the eye and say: the body you had at 25 is gone. Swinging a club at 120 mph and walking 5 miles on a golf course — that chapter is closed. And the sooner he accepts that, the sooner the next chapter can begin.
His short game alone could define an entire second career. Coaching. Broadcasting. Teaching the next generation. There’s a very bright horizon ahead — but only if he stops running his body into the ground chasing a version of himself that no longer exists.
He deserves real help. I hope he finds it.

Tiger Woods is one of the greatest athletes who has ever lived — and watching him fight through this is both inspiring and heartbreaking.
But as a pain specialist, I can tell you: there’s a right way and a wrong way to manage what he’s dealing with.
If Tiger were my patient, here’s exactly how I’d approach it:
✅ Short-acting medications only — no long-acting narcotics
✅ Zero benzodiazepines, zero alcohol, zero Soma (it breaks down into a barbiturate most people don’t even know about)
✅ Interventional options: spinal cord stimulator, radiofrequency ablation, sympathetic blocks, epidural steroid injections
✅ And the hardest one — activity modification
That last one is where most elite athletes struggle. Because when you’ve spent your entire life being defined by what your body can do, being told to stop feels like losing your identity.
But here’s what I tell every long-term athlete I’ve worked with: nobody writes a book with one chapter. Tiger’s competitive golf chapter may need to close — but coaching, broadcasting, mentorship, legacy-building? Those chapters can be extraordinary.
The more you force damaged nerves to absorb punishment, the more sensitized they become. There is a ceiling to what medicine can do. Activity modification isn’t giving up — it’s protecting everything you have left.
I hope he finds the right team. He deserves it.

Growth hormone peptides are not all the same.

And understanding the difference matters.

Here’s a simplified breakdown:

• Short-acting peptides
Mimic your body’s natural pulsatile release of growth hormone

• CJC-1295 (DAC)
Binds to albumin → longer duration of action
Creates a more sustained release

• Sermorelin
One of the most studied
Mimics your natural nighttime growth hormone pulse
Supports fat loss, recovery, and sleep

• Tesamorelin
More targeted toward visceral fat reduction
But higher doses → higher cost

Each one serves a different purpose.

So the real question is:

What outcome are you trying to achieve?

What actually causes aging?

There are many theories.

But one of the most accepted is the free radical theory of aging.

Here’s the simple version:

Free radicals are unstable molecules created by:

• Normal metabolism
• Pollution
• Radiation
• Smoking

They damage your cells by stealing electrons from other molecules.

When you’re younger, your body has a strong antioxidant system that neutralizes this damage.

But as you age…

That system weakens.

And damage begins to accumulate inside your cells — especially your DNA.

That’s when aging accelerates.

And it’s also why cellular damage is linked to diseases like cancer.

The key concept:

Aging happens when damage outpaces your body’s ability to repair itself.

Most people fail at intermittent fasting for one simple reason:

They try to go from eating all day…
to not eating at all.

Your body isn’t used to switching between insulin and fat-burning.

So when you skip meals, you feel:

Lightheaded
Hungry
Uncomfortable

And you quit.

The solution is progression.

Here’s how to start:

Day 1 → first meal at 9am
Then push to 10am
Then 11am
Then noon

Eventually, you’re eating in a 12–6 window.

What happens next:

Your body burns stored glycogen
Then begins mobilizing fat for energy

And because you built it gradually:

Hunger decreases
Energy stabilizes
Fat loss accelerates

This is the most consistent pattern I’ve seen in patients who lose significant weight.

Save this.

Peptides are one of the most misunderstood areas in health right now.

At their core, they’re just signaling molecules.

Different peptides signal different things:

• Growth hormone release
• Appetite control (GLP-1)
• Fat loss pathways
• Tissue repair and regeneration (BPC-157, TB-500)
• Immune function and cognition

Each class has a different purpose.

So the real question isn’t:

“Should I take peptides?”

It’s:

“What outcome am I trying to achieve?”

One important consideration:

Many peptides require injections — often daily.

So consistency and comfort with that process matters.

Your central nervous system is designed to learn.

But it’s also designed to forget.

Every time you repeat a movement or skill, your brain strengthens that pathway.

Over time, three things happen:

• It fires at a lower threshold (it becomes easier)
• It fires more intensely
• It lasts longer

That’s how you improve.

From coordination…
To strength…
To skill…

But the opposite is also true.

If you stop using something, your brain stops prioritizing it.

As you age, this becomes critical.

The body and brain adapt to what you do consistently.

Use it… or lose it.

Save this.

Most people know we lose flexibility as we age.

But very few understand why.

At a cellular level, three key things are happening:
1. Extracellular matrix changes
Hydration decreases → tissues become stiffer
2. Collagen changes
Less turnover + more cross-linking → reduced mobility
3. Elastin decreases
Less ability for tissue to rebound after movement

The result?

Your body becomes progressively more rigid over time.

But here’s the important part:

These changes can be slowed — and in some cases improved — with the right inputs.

I’ll cover exactly how to combat this in the next video.

When Jamie Foxx spoke at a recent awards ceremony, he said something powerful:

Six months ago he couldn’t even walk across the stage.

Now he can.

We don’t know the exact medical event he experienced.

But what we do know is that he was very physically fit before it happened.

That matters more than people realize.

After the age of 40, health isn’t just about looking good.

It’s about preparing for the hits in life that eventually come for all of us:

• Illness
• Surgery
• Injury
• Major stress

Your baseline fitness often determines how well you recover.

The stronger and healthier you are going into a crisis, the better your body can respond and rehabilitate.

Don’t wait for a health scare to start taking your physical health seriously.

Start now.

Osteoarthritis affects millions of people worldwide.

And paradoxically, one of the best treatments is something many people avoid…

Exercise.

Movement improves joint health in several ways:

• Strengthens the muscles that support the joint
• Increases synovial fluid flow (the joint’s nutrient source)
• Improves bone density
• Keeps the joint capsule flexible and mobile

In other words, movement nourishes the joint.

A simple guideline that helps many people:

20–30 minutes of low-impact exercise, 4–5 days per week.

Walking, cycling, swimming, or incline treadmill work are all great options.
