Patients ask me about peptides every week. BPC-157. TB-500. Ipamorelin. The list keeps growing.
Before I’d ever recommend one or take it myself it has to pass 4 questions:

Do we know how it actually works in the human body?
Has it been proven in real humans, not rats or cells?
Do we know the right dose from actual studies?
Do we know it’s safe long-term?

Semaglutide (Ozempic, Wegovy) passes. Most of what’s being marketed online doesn’t come close.
If you can’t answer all 4 you’re not on a treatment.
You’re running an experiment on yourself.

Save this. Send it to the friend who’s about to start.

Peptides aren’t the problem.

👉 Bad evidence is.

There are peptide-based drugs that are well-studied and widely used—like
Semaglutide—with strong human data and known safety.

Then there are the peptides most people are talking about online.

And those typically have:
• no high-quality human trials
• no long-term safety data
• no validated dosing

A common argument is:
👉 “They aren’t being studied because they can’t be patented.”

That’s simply not true.

Most peptides—whether approved or experimental—are not in their natural form.

👉 They are analogs.

They’ve been:
• modified
• stabilized
• engineered

And that makes them:
👉 patentable
👉 scalable
👉 profitable

So if one of these peptides truly delivered consistent, meaningful results…

👉 pharma would be all over it

That’s not speculation—that’s how the system works.

So when something remains in the gray zone for years…

👉 the more likely explanation is that it hasn’t held up when tested

Not that it’s being ignored.

Hormone optimization isn’t about guessing. It’s about precision.

Estradiol, progesterone, metabolic markers… they all matter.
And they all need to be interpreted in context.

No generic protocols. No one-size-fits-all plans.

A zero coronary artery calcium (CAC) score does NOT mean zero risk.

CAC detects calcified (stable) plaque—often a later-stage finding. The plaques that rupture and cause heart attacks are typically non-calcified (soft plaque), which CAC does not detect.

LDL = cholesterol content
ApoB = number of atherogenic particles (better predictor of risk)

Think: ApoB = number of particles driving plaque formation over time.

Even with CAC = 0, long-term exposure to elevated ApoB can still lead to plaque buildup and future events.

The new Dietary Guidelines push more animal foods and higher protein intake.
Some of that makes sense.

But the same guidelines still recommend keeping saturated fat under 10% of total calories, which is very hard to do on a diet built around steak, eggs, whole milk, butter, and full-fat dairy.

Saturated fat adds up quickly.
Excess intake raises LDL and ApoB, and elevated ApoB is causal for cardiovascular disease.

Eating more quality protein is a good idea.
But what you choose matters if you want to reduce long-term risk.

When nutrition advice sends mixed signals, the math needs to be explained clearly, not brushed off as “old dogma.”

Watching Peter Attia give rapid-fire longevity takes and pausing where context matters.

• Rapamycin shows its strongest human signal in older adults, mainly immune function. Not proven for younger, healthy people.
• Microplastics matter, but hot exposure is the bigger issue.
• Hormone therapy is still widely misunderstood.
• Testosterone, when used correctly, can be transformative. For women, it is often the most effective treatment for low libido, even when labs look “normal.”

Big levers. Real data. Context over hype.

Educational only. Not medical advice.

Peptides are here to stay.

Patients are going to explore whether doctors approve or not. Dismissing it doesn’t help anyone.

This space is still new. Limited regulation. Limited trial data. Variable purity and dosing.

That’s exactly why physicians need to get educated, monitor labs, and act as a safety net when complications arise.

Not anti peptide.
Pro guidance.

Why cholesterol often rises during menopause 👇

Cholesterol is the starting material for estrogen, progesterone, and testosterone.
When estrogen drops, the brain and liver try to compensate.

• Higher FSH signals the ovaries
• The liver increases cholesterol supply
• The ovaries are less responsive

The result is higher cholesterol from a hormone bottleneck, not diet alone.

Save this and share it with someone confused about their labs.
