Peptides, Menopause Brain Fog, and the Wild West of Aging Well

This month, I started something new in my own aging-well experiment.

Peptides.

Not the GLP-1 weight loss peptides everyone is talking about, these are different. I’m taking one called Glow, which is an injectable peptide blend, and another to called Semax/Selank, which is a nasal spray often used for focus, brain fog, mood, and mental clarity.

I'll admit, it feels a little weird to even write that.

Peptides feel like one of those topics that is suddenly everywhere, but still somehow underground. The early adopters are talking about them. The longevity people are talking about them. Biohackers are definitely talking about them. And now, in the last week alone, a close friend and a few family members have told me they are taking peptides too. One is taking them for muscle growth, one for sleep. I’m taking mine for recovery, skin, aging well, and brain fog. It's starting to feel a little like, wait, are these miracle drugs? Is this too good to be true?

For me, this started with menopause brain fog. I’ve been taking testosterone, and while I do think it has helped in some ways, I still don’t feel like my brain is where I want it to be. I want more clarity, and better focus. Less of that walking-into-a-room-and-forgetting-why feeling. Less searching for words or that cloudy feeling that so many women describe in midlife. That’s where Semax/Selank came in.

Then there’s Glow. From what I understand, Glow is commonly a blend of peptides like GHK-Cu, BPC-157, and TB-500, though compounded formulas can vary. These peptides are often talked about in wellness and longevity spaces for things like skin health, collagen, tissue repair, inflammation, and recovery, but I’m still learning what is actually proven, what is promising, and what is more hype than science.

Glow is injectable, which means this was the first time I have ever used a needle to put something into my body. and I had it for a couple of days before I actually used it. I kept looking at it and thinking, am I really doing this? I finally did, but I will be honest, it was a little scary. Not painful, just mentally strange. I’m not someone who casually injects things. This felt like a line I had never crossed before. That said, I’m not buying mystery powder from the internet. This is being prescribed through an MD. She researched the pharmacies I’m using, and these are coming from reputable compounding pharmacies, which matters to me a lot.

Here’s where I think it gets confusing.

Peptides are showing up in a lot of powders right now too, which are more like supplements, like collagen peptides or protein powders. They go through your digestive system and your body uses them more like building blocks.

Glow is an injectable. Semax/Selank is a nasal spray. Those are being used more like targeted compounds, not just something you stir into coffee or a smoothie. So when people say “peptides,” we really need to ask, what kind? What form? What dose? Where is it coming from? Is it prescribed? Is it tested? Is it actually getting into the body in the way people think it is? I’m not saying powders are bad. I’m saying they are not all the same thing.

And this is where I think the conversation gets important.

There are FDA-approved peptide medications. Insulin is a peptide. GLP-1 medications are peptides. But many of the peptides being talked about in the wellness and longevity world are not FDA-approved drugs for these uses.

Some are being reviewed. Some are in a gray area. Some have been sold online as “research only,” which is exactly the kind of thing that makes me nervous.

The FDA is actually looking at this space right now. There is a Pharmacy Compounding Advisory Committee meeting scheduled for July 23–24, 2026 to discuss whether certain peptides, including BPC-157, TB-500, Semax, DSIP, and others, should be considered for the 503A bulk drug substances list. That does not mean they are FDA-approved miracle treatments. It means the regulatory conversation is changing.

This is why I think peptides are such an interesting I Am Aging Well topic. They sit right at the intersection of possibility and caution. There is the exciting side; the idea that we may be able to support healing, recovery, brain function, sleep, skin, muscle, and inflammation in new ways is exciting. I am 54. I care about my energy. I care about my skin, about keeping muscle, about my brain. I care about not just living longer, but living better.

But there is also the cautious side. A lot of these peptides do not have the same level of large, long-term human research that we would want if we were calling them proven treatments. There are real concerns about quality, purity, dosing, and people getting them from unsafe places.

So where do I land right now? Curious. Hopeful. Careful. I’m not ready to tell everyone to run out and take peptides. I’m also not willing to dismiss something just because it is new, unfamiliar, or not fully mainstream yet.

That’s really what aging well has become for me. It’s not about chasing every trend, or pretending we can stop time. It’s not about being reckless with our bodies. It’s about staying open, asking better questions, working with qualified providers, and being willing to learn.

I’ll keep you posted on what I notice. I don’t expect overnight miracles, and I’m not looking for a magic fix. But I am paying attention.

To my brain.

To my skin.

To my sleep.

To my recovery.

To my energy.

To how I feel in my body.

Because aging well is not passive. It’s active. It’s curious. It’s personal. And sometimes, it means being brave enough to try something new, while still being smart enough to do it carefully.

Important note: I’m sharing my personal experience, not medical advice. Peptides should only be used under the guidance of a qualified medical provider and sourced through reputable pharmacies.
