The one side effect of testosterone therapy that Joe Rogan rarely mentions…

Let's break it down: 🧵 Image
TRT (testosterone replacement therapy) has benefits:

• Boosts energy
• Improves libido
• Builds muscle
• Elevates mood

But it comes with one serious risk... especially for younger men.
Here’s what happens when you take external testosterone:

Your brain detects high levels…

...and stops signaling your body to make more.

This causes your testicles to reduce function, shrink, and in some cases, become permanently suppressed.

This is called testicular atrophy.
TRT doesn’t just add testosterone... it suppresses your body’s natural production.

Many men become dependent.

And when you stop? Recovery isn’t guaranteed.

There are also additional risks…
Other long-term side effects of TRT:

• Mood swings
• Acne & dizziness
• Worsened sleep apnea
• Blood thickening (clot risk)
• Lower testosterone sensitivity
• Erectile dysfunction
• Possible heart complications
Why are more men seeing low testosterone before they age?

Common causes include:
• Insulin resistance
• Zinc, protein, or fat deficiency
• Statins
• Soy overconsumption
• Liver dysfunction
• Vitamin A/D deficiency
• Overtraining
• Obesity
The good news?

You can restore testosterone naturally.

Start with:

1/ Weight training
Resistance exercise triggers testosterone production better than any supplement. Image
2/ Zinc
Crucial for testosterone and sperm.
Sources: red meat, shellfish, and liver.

3/ Vitamin D
Low vitamin D = low testosterone.
Use sunlight or high-quality supplements.

4/ Healthy fats
Cholesterol → testosterone.
Eat butter, eggs, meat, and olive oil.
5/ DHEA (optional)
Supports adrenal & hormonal health.

6/ REM sleep
Sleep restores testosterone.
Prioritize deep sleep and manage stress.

7/ Lose excess fat
Fat cells convert testosterone to estrogen.
Fat loss = hormone balance.
8/ Fix insulin resistance
High insulin disrupts testosterone.

What helps:
• Ketogenic diet
• Intermittent fasting
• Cutting sugar
• Whole, nutrient-dense food

9/ Eat enough protein
Protein fuels hormone production and metabolism. Image
TRT can be useful... but it often causes shrinkage and infertility.

Low testosterone isn’t just a deficiency.

It’s a signal.

Address the root issues first:
• Nutrition
• Sleep
• Metabolism

The one mineral that over 50% of Americans are deficient in… but that they desperately need.

Here’s what it is and why it matters: 🧵 Image
Over 48% of Americans are deficient in magnesium, and most don’t know it.

NHANES data from the NIH shows nearly half of U.S. adults fall short of the recommended intake.

Standard blood tests often miss it, since over 99% of magnesium is stored inside cells, not in the blood.
Magnesium supports over 300 enzyme reactions and helps with:

• Energy production
• Muscle and nerve function
• Sleep and mood regulation
• DNA and protein synthesis
• Blood sugar and blood pressure control

Deficiency affects sleep, stress, insulin sensitivity, and more.

Why pro athletes have stopped drinking Gatorade, and why you should too.

Here’s what you need to know: 🧵 Image
Gatorade has long been marketed as the ultimate performance drink: hydration, electrolytes, energy.

For decades, athletes trusted it to fuel their workouts and speed up recovery.

But a closer look at the label reveals why more athletes are walking away from it.

Let me explain:
What’s really in a bottle of Gatorade?

• 21 grams of sugar per 12 ounce
• Synthetic dyes like yellow 6
• Almost no potassium or magnesium
• Brominated vegetable oil (a potential hormone disruptor)

In short, you’re drinking sugar water with added salt and chemicals.

Why using hand lotion actually DRIES OUT your hands…

It’s not moisturizing. It’s masking the problem.

Let me explain: 🧵 Image
You use lotion to fix dry hands.
But the more you use it, the drier they get.

That’s because most lotions contain alcohol.
It evaporates quickly, giving a light, clean feel.

But it also strips your skin’s natural oils, breaking down the barrier that holds in moisture.
Your hands feel tight, so you reach for more lotion.
Then more.

But they stay dry, cracked, and start to show signs of aging.

You’re stuck in a cycle, and the lotion is making it worse.

What your skin actually needs is something it once produced in abundance: hyaluronic acid.

Autism rates are EXPLODING!
In 1980, 1 in 10,000 kids had autism.
Today, it’s 1 in 36.

That’s a 27,000% increase!

We’re told it’s a mystery—mostly genetic, no known cause.

But is there a connection between autism & vaccines?

Let’s take a closer, evidence-based look:

THREAD🧵 Image
According to leading medical authorities, the cause of autism remains unknown.

It’s widely considered to be genetic—possibly environmental.

But one explanation is consistently dismissed: vaccines.

Meanwhile, autism rates have surged—and nobody seems to want to talk about why.
In 1980: 1 in 10,000 kids had autism.
By 2023 that number had risen to 1 in 36.

During the same period, the childhood vaccine schedule expanded dramatically:
• From 12 to 49 doses by age 6
• Aluminum: from 250 mcg to 5000 mcg

Yet any link is considered off-limits to question. Image

This is why you’re always TIRED…

Most people don’t know what’s really draining their energy.

Here are 7 causes, and how to fix them: 🧵 Image
1/ Poor sleep quality

Getting 7–8 hours doesn’t mean you’re well-rested.
What really matters is deep, restorative sleep.

What ruins it:
• Eating too late
• Alcohol
• Overtraining (raises adrenaline)
• Eating chocolate late in the day

So how do we fix it?
How to fix poor sleep quality:

• Stop eating 3+ hours before bed
• Avoid alcohol and stimulants at night
• Take magnesium glycinate to relax
• Add vitamin B1 if stressed or eating lots of carbs

Bonus:
Morning sunlight (6–8:30 a.m.) resets your body clock and improves sleep. Image

“Grass-fed” beef is a SCAM…

Don’t trust the label. There’s a massive loophole behind it.

Let’s break it down: 🧵 Image
In 2016, the USDA dropped its official definition of “grass-fed.”

Since then, companies can use the label even if the cow spent its final 3 to 6 months eating grains, GMO byproducts, and synthetic additives.

Most people have no idea.

Why does this matter?
This is important because the final stage of a cow’s life has the biggest impact on your health.

In the last 3–6 months, cows are moved to feedlots and fattened fast.

They’re fed DDGS—a cheap industrial byproduct from ethanol production.

It’s not food. It’s waste.
