"What if the “new” wellness trend everyone is suddenly talking about is actually built on some of the oldest, most well-established biology in modern medicine?”
In this episode of The Ageless Woman Podcast, Dr. Cindy Grow, APRN takes a closer look at peptides—what they actually are, how they work in the body, and why interest in peptide therapy has exploded across women’s health, longevity medicine, and mainstream wellness culture.
This conversation is not about hype, and it is not about fear either.
It is about understanding the real biology behind peptides—so you can tell the difference between genuine science and social media noise before you ever consider trying one.
Together, we explore what peptides are and why they matter, including:
• What a peptide actually is—and how it differs from a full protein
• How peptides act as signaling molecules, binding to receptors like a key fits a lock
• Why so many peptides are given by injection rather than by mouth
• Why peptides are not a brand-new area of medicine—and how insulin, oxytocin, and other familiar hormones are peptides too
• Why interest in peptide therapy has grown so quickly across women’s health, longevity medicine, and mainstream wellness
• The role GLP-1 medications like semaglutide and tirzepatide have played in bringing “peptides” into everyday conversation
• How the longevity movement and social media have accelerated interest—for better and for worse
• Why women in midlife are increasingly seeking root-cause answers instead of being told their symptoms are “just aging”
• What the current research does—and does not yet—support
• Why some peptides carry FDA approval and large clinical trials, while others are still earlier in the research and regulatory process
• Why “are peptides safe” is too broad a question—and why the specific compound, the goal, and the evidence behind it are what actually matter
• Three common peptide myths, and why believing them can put your safety at risk
One of the biggest messages from this episode is that peptides are not one single thing.
They are a category—one that already includes hormones your body has been making your entire life, alongside a newer generation of compounds still being studied.
Insulin is a peptide.
Oxytocin is a peptide.
Glucagon is a peptide.
Your body is not encountering something foreign when it responds to a peptide signal—it is responding to a language it already speaks.
And that is why conversations about peptide therapy need to begin with real biology, not headlines.
At My Venus Club, our philosophy is centered on precision—looking at your specific signaling, your specific labs, and your specific biology, instead of a population-wide average. Peptide science fits into that larger philosophy, but it is one tool among many, not a shortcut around understanding your own body.
The excitement around peptides is real.
But excitement is not the same thing as evidence.
The goal of this episode is not to tell you that every peptide is proven, safe, or right for you. It isn’t that simple.
The goal is to understand what peptides actually are...
recognize which claims are backed by real research...
separate mechanism from proof...
and give you the foundation to ask better questions before you ever consider trying one.
Because understanding your health is not simply about keeping up with the latest trend.
It is about knowing enough to tell the difference between real science and social media noise—and choosing care that is built on both expertise and evidence.
And as Dr. Grow always says:
“You can’t optimize what you don’t understand.”
This is Part 1 of a 3-part series on peptides. In Part 2, we explore why not all peptides are created equal—and why sourcing, sterile compounding, and LegitScript certification matter so much. In Part 3, we cover stacking, dosing, and why cycling off peptides is critical.

EPISODE 1 — "Peptides 101" — What Peptides Actually Are
FAQ: Quick Answers
Q: What are peptides?
A: Peptides are short chains of amino acids — generally 2 to 50 of them — that act as signaling molecules in the body. The body naturally produces peptides like insulin, oxytocin, and glucagon.
Q: How do peptides work in the body?
A: Peptides bind to specific receptors on the surface of cells, much like a key fitting a lock, which triggers a response inside that cell. Most peptides work through what are called G protein-coupled receptors.
Q: Why are peptides usually injected instead of taken as a pill?
A: Because stomach acid and digestive enzymes are designed to break down peptide bonds during digestion. Injecting bypasses digestion so the peptide reaches the bloodstream intact.
Q: Are peptides FDA-approved?
A: Some are. Semaglutide, tirzepatide, and teriparatide are FDA-approved and backed by large clinical trials. Many other widely-discussed peptides have promising early research but not yet that same scale of evidence, and the regulatory landscape is still evolving.
