What Is a Longevity Clinic? How It’s Different from a Med Spa

Key takeaways

• Choose by checklist, not by label: a board certified provider, labs before hormones, tailored dosing, clear prices, and planned rechecks.
• Verify credentials yourself: board certification in a clinical field, plus training in anti-aging, functional, or regenerative medicine.
• Ask for a 50+ biomarker panel with thyroid, adrenal, metabolic and inflammation markers, plus sex hormones and SHBG.
• Walk away from any clinic that prescribes hormones without labs or pushes big packages before your first visit.
• A med spa treats how you look. A longevity clinic tests and treats why you are aging.

Search for anti-aging care in Ann Arbor and you will see three labels. Med spas focus on cosmetic treatments. Anti-aging clinics promise to turn back the clock. Longevity clinics, or longevity doctors, promise to slow aging from the inside. The labels overlap, and some clinics use them loosely. What matters more is what happens inside the door. Who designs your plan? What gets tested? How are you followed up? This guide gives you a checklist, the credentials to verify, and the red flags. Then it explains how a longevity clinic differs from a med spa.

At Arbour Longevity in Ann Arbor, we practice longevity medicine. It is a full model, backed by evidence, that treats the root causes of aging, not just the surface. Already shortlisted us?

What Should You Look For in a Longevity or Anti-Aging Clinic?

Whatever the sign on the door says, judge a clinic by these six things. Then verify the credentials and ask how labs are used, which we cover next.

1. A board certified provider with hormone and regenerative training

Who designs your plan matters most. Look for someone who is board certified, not just licensed. They should have training in hormone therapy, peptides, or regenerative medicine, and be certified in functional medicine. At Arbour, Gandhi Bhattarai, FNP-BC, PMHNP-BC, Anti-Aging/Functional Medicine BC is triple board certified. Her fields are family practice, psychiatric mental health, and anti-aging and functional medicine. She also owns the practice.

2. Full lab work, not just "hormone levels"

Hormone levels alone are not enough. Some clinics check only testosterone (the main male sex hormone; women make it too, in smaller amounts) or estrogen (the main female sex hormone). That misses the full picture. The best clinics run full panels. Look for:

• Thyroid function: TSH, free T3, free T4, and reverse T3. TSH is the brain's signal to the thyroid. Free T3 and free T4 are the active hormone in your blood.
• Adrenal markers: cortisol (the stress hormone) and DHEA-S (an adrenal hormone your body turns into sex hormones).
• Metabolic markers, which show how well your body turns food into energy. These are fasting insulin, HbA1c (your average blood sugar over three months), and a lipid panel (a cholesterol and blood-fat test).
• Inflammation markers (the body's alarm response, stuck on low): hs-CRP (a blood marker of inflammation) and homocysteine.
• Sex hormones with their binding proteins. SHBG is a protein that grabs hormones so your tissues cannot use them. Free testosterone is the share your body can use. Estradiol is the strongest form of estrogen.
• Nutrient levels: vitamin D, B12, magnesium, and zinc.
• Body composition: how much of your weight is muscle versus fat.

Arbour's initial panel includes 50+ biomarkers (measurable signs in your blood). Good decisions need data, not guesswork.

3. Tailored plans, not one-size-fits-all

Avoid any clinic that gives every patient the same hormone dose or the same peptide stack. Peptides are short chains of amino acids that act as signals telling cells what to do. Good care is tailored to your lab results, symptoms, goals, history, and lifestyle. Your plan should change over time as your body responds and your markers shift.

4. Evidence-based treatments with real outcomes

A credible clinic offers a full toolkit, not one treatment. The treatments with the strongest evidence include:

• Bioidentical hormone replacement therapy (BHRT) for men and women, including thyroid. Bioidentical means the hormone has the same structure as the one your body makes.
• Peptide therapy for recovery, body composition, and cell health.
• NAD+ IV therapy for cell energy and repair. NAD+ is a molecule each cell needs to make energy and repair DNA.
• PRP and regenerative therapy for tissue repair. PRP is platelet-rich plasma, a concentrate of your own blood platelets. Regenerative medicine helps the body repair its own tissue instead of masking symptoms.
• Body composition programs that protect lean muscle while you lose fat.
• Targeted vitamin, mineral, and supplement plans.
• Functional medicine principles that look for root causes rather than masking symptoms.

Be cautious of clinics that lean on unproven treatments. The same goes for secret blends with unlisted ingredients, or treatments that sound cutting-edge but lack published data.

5. Clear pricing and no upselling

The best clinics are upfront about what treatments cost. At Arbour, your first visit is $35, and that fee is applied toward your treatment plan. Programs are priced clearly:

• Medical weight loss from $299/month.
• Peptide therapy from $399/month.
• Memberships from $199/month.
• BHRT pricing is discussed at your first visit.

There are no surprise charges and no pressure to buy packages you don't need. HSA and FSA cards are accepted. That openness is itself a filter. Most clinics in this area do not publish prices at all.

6. Telehealth and ongoing follow-up

This kind of care is not a one-visit fix. Look for a clinic that offers telehealth follow-ups and regular lab rechecks. Expect rechecks every 6 to 12 weeks at first, then twice a year. Doses should be adjusted to how you respond, not how the average patient does.

Which Credentials Should You Verify?

The field has grown fast. Not everyone has the training to back up the label. Check for:

• Board certification in a relevant clinical field: family medicine, internal medicine, or as a nurse practitioner.
• Extra training or board certification in anti-aging, functional, or regenerative medicine.
• Active membership in groups such as the American Academy of Anti-Aging Medicine (A4M) or the American Association of Nurse Practitioners (AANP).

Your provider's training shapes the quality and safety of your care. At Arbour, Gandhi Bhattarai holds three board certifications. They are Family Nurse Practitioner (FNP-BC), Psychiatric-Mental Health Nurse Practitioner (PMHNP-BC), and Anti-Aging/Functional Medicine. This mix is uncommon. It means she looks at the physical, mental and functional sides of aging in the same visit. That runs from hormone and metabolic health to the mental health effects of aging, stress, and body image. It helps when your symptoms cross specialty lines. She also owns the practice, so the clinician who reads your labs is the one who writes your plan.

Clinicians in this field also need to know the science of cell aging. Zheng et al. (2024) published a full review in Aging and Disease on targeting cellular senescence. Senescent cells are aged cells that stop dividing but do not clear away. The authors note that the growing challenge of aging demands clinicians who understand both senolytics and senomorphics. These are compounds that remove or modify senescent cells, and they are becoming central to anti-aging therapy (DOI: 10.14336/AD.2024.0206).

That depth of science is what sets a longevity practice apart from a purely cosmetic one.

Why Does a Lab-First Approach Matter?

In quality longevity care, data drives treatment choices, not symptoms alone. Your plan should begin with numbers, not a menu of services. At Arbour, labs are ordered at the first $35 visit and reviewed in detail at a follow-up. Each marker is checked against optimal ranges. Broad "normal" ranges can miss early problems. Follow-up labs then track progress, guide dose changes, and confirm the plan is working. This feedback loop is the hallmark of good care. It is rare in cosmetic-only practices.

What Are the Red Flags?

Not every clinic that offers these services can deliver safe, effective results. Be cautious if a clinic:

• Has no board certified provider on staff, or lacks the right training.
• Relies mainly on aesthetics (Botox, fillers) and calls it "anti-aging."
• Prescribes hormones without full lab work first.
• Uses cookie-cutter dosing with no tailoring.
• Does not recheck labs regularly (every 6 to 12 weeks at first, then twice a year).
• Cannot explain how its treatments work.
• Pushes long-term contracts or large upfront packages before your first visit.

Real longevity care is backed by evidence, tailored to you, and open about costs and expected outcomes. Planning an aesthetic treatment? See our guide to the 5 questions to ask before an aesthetic treatment.

Who Benefits Most from a Longevity Clinic?

This care is not only for older adults. Patients in their 30s, 40s, 50s, and beyond come to Arbour for care before problems start. You may benefit if you:

• Feel that your energy, focus, or drive have declined despite a healthy lifestyle.
• Want to understand and address the biology behind your aging.
• Are interested in hormone therapy, peptides, or regenerative medicine.
• Have tried cosmetic treatments but want a fuller approach.
• Value care backed by evidence, with ongoing follow-up.
• Want a provider who treats the whole person, not just single symptoms.

Why Ann Arbor, and Why Arbour Longevity?

Ann Arbor sits next to the University of Michigan Medical Center. That creates an unusual setting for advanced clinical care. Providers here tend to be better informed, better trained, and held to higher standards than the typical med spa. You benefit from that. You still need to know what sets a results-driven practice apart from a cosmetics-first business.

Arbour Longevity was built for people who want more than surface-level wellness. What sets it apart is that everything sits under one roof. That includes hormone therapy, peptides, NAD+ IV, PRP and other in-office protocols, metabolic health, and health coaching. One clinician runs all of it. Your hormone plan is informed by your metabolic data. Your peptide plan fits your IV and nutrition plan. There is no bouncing between specialists who do not talk to each other. Each patient starts with a 50+ biomarker panel. Plans are adjusted over time with lab reviews and telehealth check-ins. There is no upselling, no proprietary blends, and no pressure.

Arbour Longevity is at 2217 Packard St #15 in Ann Arbor. We serve Ypsilanti, Saline, Dexter, Chelsea, and Milan for hormone therapy. We also see peptide therapy patients from Ypsilanti, Dexter, Saline, Chelsea, and Milan. Patients come from the wider Washtenaw County area and across Southeast Michigan. Telehealth follow-ups are available for Michigan residents statewide.

How Is a Longevity Clinic Different from a Med Spa?

What a med spa does well, and where it stops

Med spas have grown fast over the past decade. Many provide excellent cosmetic care. A typical med spa offers neuromodulators like Botox (shots that relax the small muscles behind expression lines), fillers, facials, and skin tightening. The focus is on looking better, often with quick, visible results.

Most med spas work within a narrow scope. Treatments tend to be one-off. You come in for one procedure, get the service, and leave. There is usually little attention to the biology behind what you see in the mirror. Your skin may be aging fast because of chronic inflammation, a hormone imbalance, or a metabolic problem. A med spa may treat the symptom. It rarely looks for the underlying cause.

This is not a criticism of cosmetic care. Aesthetic treatments have real value for confidence and well-being. But they are one piece of a much larger puzzle.

What a longevity clinic does differently

A longevity clinic starts from a different question. It does not ask how to make you look younger. It asks why you are aging this way, and what can be done at the cell level.

Standard medicine is built to treat disease after it shows up. You get symptoms, see a doctor, get a diagnosis, and get treatment. That reactive model works well for acute illness and emergencies. It is not built to prevent the slow decline that begins decades before a diagnosis.

This model works the other way round. The goal is to find and fix the drivers of aging before they cause symptoms or disease. That means working on hormone levels, metabolic health, body composition, cell energy, inflammation, and nutrient status. It relies on lab data, not guesswork. Think of the check engine light. One model waits for it. The other runs regular checks to catch problems early.

This model now has an expert framework behind it. A 2026 Delphi-derived expert consensus in Aging and Disease set out clinical guidelines for healthspan-focused care. Healthspan is the number of years you live in good health. The framework combines existing cardiometabolic guidelines (heart, blood vessel and metabolic care) with the fast-growing field of healthspan medicine. Its target is intrinsic capacity and biological aging, not just disease treatment (DOI: 10.14336/AD.2026.0279).

Longevity medicine is not a fringe idea. Major medical centers, including those linked to Harvard, Stanford, and the National Institutes of Health, now run their own aging research programs. The field draws on geroscience, the study of the biology of aging. Its goal is to target the root causes of age-related decline rather than manage each disease after it develops.

The Four Pillars of Longevity Medicine at Arbour Longevity

Pillar 1: Hormone Optimization

Hormone decline is one of the biggest drivers of aging. Five hormones matter most:

• Testosterone: drives sex drive, muscle, energy, and mood.
• Estrogen: men need a small amount too, for bone and brain.
• Progesterone: the hormone that balances estrogen and supports sleep.
• Thyroid hormones: they set your metabolic speed.
• DHEA: a marker of adrenal reserve.

Together they shape energy, body composition, thinking and memory, mood, and skin quality. At Arbour, we use full lab panels and BHRT to bring hormones to optimal levels, not just "normal" ranges.

Pillar 2: Metabolic Health

Metabolic problems speed up aging across the board. Three matter most:

• Insulin resistance: cells stop responding to insulin, so blood sugar and belly fat rise.
• Chronic inflammation.
• Mitochondrial decline: the tiny power plants in your cells make less energy.

Excess adiposity (body fat) may speed up biological aging in a clinically relevant way. A 2026 review proposed that it switches on core aging hallmarks too early. Those include cellular senescence and epigenetic drift (Correa-Burrows et al., Metabolism, 2026, DOI: 10.1016/j.metabol.2026.156634). We address metabolic health through:

• Medical weight loss programs.
• Advanced lab testing.
• Peptide therapy.
• Lifestyle changes.

Pillar 3: Cellular Repair and Regeneration

At the cell level, aging is driven by a build-up of senescent cells, mitochondrial problems, DNA damage, and used-up stem cell reserves. This care targets these directly. The tools include peptides, regenerative treatments, and support for your body's own repair.

Pillar 4: Regenerative Aesthetics

This is where the two models overlap, with one key difference. At Arbour, Botox, fillers, and plasma soft surgery are part of a wider health plan. When your hormones are balanced, your metabolism is working, and your cells are healthy, aesthetic treatments work better and last longer.

Longevity Clinic vs. Med Spa: Side-by-Side Comparison

Frequently Asked Questions

Is a longevity clinic more expensive than a med spa?

Up-front testing and a full treatment plan may cost more at first. Many patients find it gives better long-term value, because it treats root causes rather than repeating symptom fixes. When your core health improves, you often need fewer cosmetic touch-ups over time. Our program pricing is published, which most clinics in this area do not do.

Can I still get Botox and fillers at a longevity clinic?

Yes. At Arbour Longevity, we offer a full range of aesthetic treatments, including Botox, fillers, and advanced skin renewal. The difference is that these treatments are part of a wider health plan rather than offered on their own.

Do I need to stop seeing my dermatologist or primary care provider?

No. This care works alongside your current medical care. We work with your other providers so your care stays joined up.

What kind of lab work is involved?

Typical panels include a full metabolic profile, complete hormone panels, inflammation markers, thyroid function, and lipid panels. Insulin and glucose markers are included too, plus other biomarkers tailored to your concerns and goals. Details are on our advanced lab testing page.

How do I know if longevity medicine is right for me?

If you want a science-based approach to aging that goes beyond cosmetics, this care may be a good fit. Schedule a visit at Arbour Longevity to talk through your goals. We see patients from across Washtenaw County.

If you want a clinic that puts depth ahead of cosmetic flash, book your $35 first visit or call (734) 436-3357. The $35 is applied toward your treatment plan. The visit is 30 to 45 minutes with Gandhi Bhattarai. It includes a review of your history, lab orders, a first roadmap, and clear next steps. No referral is needed.
