Peptides for Men Over 40

Behind every hot, successful man over 40… is a great clinical-grade peptide stack.

Kidding. Mostly.

Two things on this page: exactly what my husband Mike takes (look for the green check), and the other peptides I'd have every guy over 40 think about.

28 years together. Old football injuries. A high-stress job.

Mike's body has taken a beating, and his job doesn't give him a break. He's also not on testosterone, and doesn't want to be.

Peptides changed that for him: less inflammation, injuries that finally healed, a completely different body composition, more energy, and a calmer guy coming home at night.

Mike's results are his own. Everyone's body is different, and every prescription goes through a licensed physician first.

The peptides I'd have every man over 40 look at

Mike's stack = what Mike takes. Everything without a check is another one worth thinking about.

Body CompositionMike's stack

Tesamorelin

Body composition, belly fat, energy

I can't explain enough how much of a difference this has made in Mike's body composition. Tesamorelin signals your body to release more of its own growth hormone. It's best known for reducing belly (visceral) fat, and a lot of people notice more energy and better recovery too.

Fun fact: Mike has an upper body injury and can't lift. I still caught myself asking, "Have you been lifting again?" We also tested his testosterone before and after: up about 30%. That's his own result, not what it's prescribed for. Cycle off several times a year.

RecoveryMike's stack

Wolverine

BPC-157 + TB-500 for injuries & recovery

The staple. BPC-157 and TB-500 are two repair peptides studied for healing tendons, ligaments, muscle and gut lining, and they're often paired because they support recovery in different ways. For the guy who still plays like he's 25 and recovers like he's 45.

Mike's upgrade: GLOW, which is Wolverine plus GHK-Cu for skin, hair and collagen. When he cycles off GLOW, he takes Wolverine.

Physical EnergyMike's stack

MOTS-c

Energy, metabolism, performance

MOTS-c is a peptide your own mitochondria make, the part of every cell that turns fuel into energy. It's studied for energy, insulin sensitivity and exercise performance. I think of it as physical energy. We cycle it on and off.

One friend's labs on MOTS-c alone: inflammation down 76%, triglycerides down 38%, LDL down 31%, ApoB down 16%, testosterone up 24%. One athlete, one set of labs, but I had never seen numbers like that.

Mental EnergyMike's stack

NAD+

Focus, cognitive energy, cellular health

NAD+ is a molecule every cell needs to make energy and repair DNA, and levels drop as we age. If MOTS-c is physical energy, NAD+ is the mental side: sharper, clearer, and just good for you.

Inflammation & LongevityMike's stack

Tirzepatide (Microdose)

The one that shocks everyone

Tirzepatide is a GLP-1/GIP medication, best known for weight loss. That's not why Mike takes it. At a microdose that doesn't suppress his appetite, this is what calmed Mike's inflammation from old football injuries and took the edge off his anxiety.

His knee injury that wasn't healing with anything else? About three weeks after I started him on it, it was better.

My take: at a low dose, I see it as one of the best longevity tools out there.

Stress & Calm

Selank

Stress and calm without sedation

Selank is a peptide studied for anxiety and stress, designed to calm you down without the sedation or dependency of anti-anxiety meds. For the guy carrying everything. It comes paired with Semax, a sister peptide studied for focus.

Sexual Health

PT-141

Desire & arousal, as a nasal spray

Taken as needed, not daily. Works on desire in the brain rather than blood flow.

Nasal spray link coming soon. DM me in the meantime for details.

Testosterone Support

Enclomiphene

Not a peptide, but worth knowing

An oral prescription that signals your body to make more of its own testosterone. An option for men who aren't ready for TRT.

Growth Hormone

CJC-1295 + Ipamorelin

Popular for sleep & recovery

Like Tesamorelin, this pair signals your body to release more of its own growth hormone, in natural pulses. CJC-1295 extends the signal and Ipamorelin triggers the release. Men use it for deeper sleep, recovery and lean muscle.

A lot of men really love this one. For us personally, Tesamorelin was the better fit.

Run your labs first

You can't optimize what you haven't measured. Here's what to ask for, and what each one tells you.

Total & free testosteroneYour actual testosterone, and how much is free to use. Low free T can explain low energy, low drive and stubborn belly fat, even when total looks "normal."
Estradiol & SHBGEstradiol is estrogen, which men need in balance for mood, libido and body fat. SHBG locks testosterone up; high SHBG means less free T available.
PSAYour prostate baseline. Important to know before anything that raises testosterone.
A1c & fasting insulinA1c is your average blood sugar over about 3 months. Fasting insulin shows how hard your body works to keep it there, and often rises years before A1c does.
Lipids & ApoBApoB counts the particles that actually build plaque in arteries. A sharper read on heart risk than LDL alone.
Thyroid panelA slow thyroid can look a lot like low T: tired, cold, weight creeping up, brain fog.
CBC & CMPThe safety check: blood counts, liver and kidney function. Your baseline before starting anything new.
hs-CRPBody-wide inflammation. If it's high, something (injury, gut, blood sugar) is driving it, and that's where to start.

Your provider reads your results with you. This is what to ask about, and why it matters.

Research peptides vs. clinical grade

Every man I talk to has heard about peptides from his gym bros, usually research peptides ordered online.

I used to use research peptides. Now I use clinical grade, and the difference I've seen is night and day.

Research peptides all say "third-party tested, 99.9% pure." But who's actually checking that? They're sold "not for human use," with no prescription and no one accountable for what's in the vial. Everything on this page is prescribed by a licensed physician and made by a licensed 503A compounding pharmacy.

And no, clinical grade doesn't have to mean crazy expensive. I comparison-shopped for months, and code KATE30 takes 30% off on top.
