Q: Do you offer regenerative treatments for joint pain, hair loss, or sexual health?

Yes. We use PRF (platelet-rich fibrin) —a regenerative treatment that uses your body’s own healing factors—for joint pain, hair restoration, and sexual wellness. These are often combined with hormone therapy or NAD+ to enhance overall results.

Q: How did RegenCen start, and who leads your medical team?

RegenCen was co-founded by Dr. Gustav Lo , a physician with over 30 years of experience in primary care and a deep focus on preventive and regenerative medicine and Courtney Lo, PA , who has spent her career in anti-aging and aesthetics at Cosmetic Skin and Laser Center. They created the RegenCen to offer a more thoughtful, personalized approach to aging—one that treats root causes, not just symptoms. Dr. Lo and Courtney continue to lead RegenCen’s clinical direction, working closely with our experienced team of providers to deliver science-backed, individualized care across all of our locations.

Question 1

What is RegenCen and what treatments do you offer?

Accepted Answer

RegenCen is a medical clinic focused on longevity, hormone optimization, and regenerative wellness. We offer advanced, science-backed services including bioidentical hormone therapy, semaglutide and tirzepatide for medical weight loss, NAD+ therapy, sexual wellness treatments, and PRF injections for joint pain, skin, and hair restoration.

Question 2

Do you offer NAD+ IV therapy at all RegenCen locations?

Accepted Answer

Yes. NAD+ therapy is available at every RegenCen location. It helps restore energy, improve brain function, support metabolism, and slow aging by replenishing the cellular coenzyme NAD+, which declines with age.

Question 3

Can I get semaglutide or other weight loss medications through RegenCen?

Accepted Answer

Absolutely. Our weight loss program includes GLP-1 medications like semaglutide and tirzepatide, paired with lab work, hormone evaluation, and ongoing clinical support. We address root causes—like insulin resistance and hormonal shifts—so you can lose weight and keep it off.

Question 4

Do you offer hormone therapy for both men and women?

Accepted Answer

Yes. We treat men and women using bioidentical hormone therapy customized to your lab results and symptoms. Whether it’s perimenopause, menopause, or low testosterone, our providers address fatigue, weight changes, brain fog, low libido, and more—often in as little as a few weeks.

Question 5

Do you offer virtual appointments?

Accepted Answer

Yes—RegenCen offers virtual consultations (by video or phone) for patients in both Michigan and Florida. Just text or call us to schedule your telehealth visit and discuss treatment options from home.

Question 6

Do you offer regenerative treatments for joint pain, hair loss, or sexual health?

Accepted Answer

Yes. We use PRF (platelet-rich fibrin)—a regenerative treatment that uses your body’s own healing factors—for joint pain, hair restoration, and sexual wellness. These are often combined with hormone therapy or NAD+ to enhance overall results.

Question 7

What makes RegenCen different from telehealth clinics or IV bars?

Accepted Answer

RegenCen provides care in a medical setting, led by experienced providers who specialize in aging and hormone health. We don’t offer one-size-fits-all plans—we use bloodwork, hormone optimization, and advanced diagnostics to design your personalized plan. And because we’re co-located with CSLC clinics, you also get access to aesthetic and skin rejuvenation treatments under the same roof.

Question 8

How do I get started at RegenCen?

Accepted Answer

Start by booking a consult at your closest RegenCen location or via telehealth. We’ll review your symptoms, order lab work if needed, and create a treatment plan that fits your lifestyle, timeline, and goals. Most patients begin with a focus on hormones, energy, or metabolic health.

Question 9

Where are RegenCen clinics located?

Accepted Answer

You’ll find RegenCen in cities across Michigan and Florida including Petoskey, Ann Arbor, Naples, Palm Beach, Winter Park, and more. See all locations

Question 10

How did RegenCen start, and who leads your medical team?

Accepted Answer

RegenCen was co-founded by Dr. Gustav Lo, a physician with over 30 years of experience in primary care and a deep focus on preventive and regenerative medicine and Courtney Lo, PA, who has spent her career in anti-aging and aesthetics at Cosmetic Skin and Laser Center. They created the RegenCen to offer a more thoughtful, personalized approach to aging—one that treats root causes, not just symptoms.

Dr. Lo and Courtney continue to lead RegenCen’s clinical direction, working closely with our experienced team of providers to deliver science-backed, individualized care across all of our locations.

Question 11

Do you offer testosterone replacement therapy (TRT) for men?

Accepted Answer

Yes. We specialize in personalized testosterone therapy for men with symptoms of low T—like fatigue, low libido, weight gain, and brain fog. At RegenCen, TRT isn’t just about a number—we assess hormone levels, symptoms, and overall health to design a safe and effective program. Many men also combine TRT with NAD+ or semaglutide for full-body optimization.

Question 12

What are the best regenerative treatments?

Accepted Answer

1. Bioidentical hormone replacement therapy (BHRT) is the foundation of regenerative medicine. Hormone levels drop with age. By age 55, testosterone is about half what is was in men in their 20’s; it’s worse in women - 80% lower than young normal levels! These low levels have major health consequences. Over 75% the improvement listed above can be achieved just with BHRT.
2. NAD+, a crucial coenzyme for energy production in our cells, also drops by 50% in middle age. With less NAD+, there is simply less fuel available to burn, so our bodies slow down. I liken it to a car that has 8 cylinders when it’s 20 years old, but by the time it’s 50, it’s running on 4 cylinders - the engine is weak, it has a hard time going uphill, and passing is sometimes impossible. NAD+ opens up those other 4 cylinders, making more energy by burning more fuel. That V-8 is great for our bodies because we want to burn more fuel to get rid of excess calories and fat. More than that, NAD+ supplementation is proven to rev up fading function in the liver, muscle, and your brain - who going to say no to that?
3. PRF injections for joint regeneration is one of the most well-studied regenerative treatments available, with research consistently showing 75% response rate in osteoarthritis with this simple, in-office procedure. It’s called the “poor man’s stem cells” because it’s simpler and much less costly than stem cell treatment with nearly the same success rate. In my practice, it’s the most effective non-surgical treatment for arthritis I’ve ever used, and that includes steroids or cortisone shots.
4. Vaginal rejuvenation and bladder control are frustrating issues - virtually every woman can benefit from these treatments at some point, but nobody ever wants to talk about them! Well, welcome to RegenCen, where we talk about them A LOT. Vaginal and pelvic tissues have many different functions, but everything from childbirth to birth control pills to menopause gets in the way of normal function. Women put up with dryness, irritation, pain, they let their sexuality fade away, they plan their day based on the chain of restrooms they have to visit… all because they don’t know effective treatment is available for all these problems. Most of the time, their doctors don’t know either. But at RegenCen, we do know - and we actually want to talk with you about it.
5. Prescription treatments for circulatory issues - this is probably the only category that we can say helps patients liver longer. Whether non-prescription supplements or widely used prescription circulation enhancers like tadalafil (Cialis) or ARB-inhibitors (valsartan, telmisartan, or anything else ending with -sartan), any treatment that improves blood flow to our tissues also lowers blood pressure and wear and tear on our circulatory system, lowering risks of heart attack and stroke. We don’t prescribe these specifically to treat high blood pressure, but it’s a nice benefit.
6. Weight loss treatments go hand-in-hand with many regenerative therapies. Most of our bioidentical hormone replacement patients lose weight (or lose fat and gain muscle). But for patients whose main goal is weight loss, we offer a weight loss program that we can tell you about at your complimentary consultation. Our program includes multiple treatments to help you lose weight and manage your weight as time goes on.

Question 13

What is a regenerative medical practice?

Accepted Answer

Regenerative medicine is a medical specialty focused on healing conditions that occur mainly from aging, but there is crossover with health problems from lifestyle or injury. Regenerative medical treatments promote new tissue growth, blood flow, nerve function, and general sense of vitality and energy. Regenerative practices employ a variety of proven therapies such as platelet-rich plasma, platelet-rich fibrin, radiofrequency devices, EMS, and hormone replacement therapy to achieve these results. By stimulating your body to grow new cells or reactivate dormant ones, regenerative medicine can help you regain lost physical functions.

Question 14

How do regenerative treatments differ from regular medicine?

Accepted Answer

Medicine has always been based on treating disease or injury, which only affect some of us. Regenerative medicine treats age-related conditions that eventually affect all of us. Think of it this way: when we’re young and our bodies are functioning at their at their best, everything works like it’s supposed to. When cells are damaged (an injury, for example), the body heals orregeneratesold ordamaged tissueto return to normal. But as we age, those regenerative abilities fade; old or damaged cells aren’t replaced, so physical abilities in our muscles, joints, nerves, and other organ systems fade. Regenerative treatments weredeveloped and studied to combat the biology of aging and awaken your body’s ability to regrow cells and tissues and return to more youthful function.

One of the best comparisons between conventional and regenerative medicine is arthritis. If you have an arthritic knee and you get a "cortisone shot" or take Aleve, your pain feels better because those drugs calm down the inflammation and pain from arthritis. With a PRF injection, your body uses growth factors from your own blood to stimulate regrowth of critical parts of the joint such as cartilage, ligament, and even bone. Revitalized tissues heal the joint so it functions properly, which then gets rid of the inflammation. With that healing, results last much longer, without the risks of a cortisone shot.

Question 15

Do I still see my primary care physician or surgeon when I come to RegenCen?

Accepted Answer

Absolutely. Our treatments complement traditional medicine. Regenerative treatments can be done anytime. They work independently and they virtually never interfere with conventional drugs or treatments, and often boost the results you're getting from those other treatments.

Regenerative treatments are targeted toward specific complaints. We currently have highly effective treatments for arthritis, urinary function and control, and sexual health for both men and women in both Petoskey and Traverse City.

Examples of changes our patients experience after treatment include:

canceling or delaying joint surgery because arthritic pain is gone
no longer taking anti-inflammatory drugs for pain because the joint pain and range of motion is better
improved erections without prescription drugs like Viagra
no longer needing panty-liners or feminine pads because bladder leakage is gone
better sleep due to less nighttime urination
enjoying intercourse because of better natural vaginal lubrication

Question 16

Why is regenerative medicine so popular?

Accepted Answer

These breakthrough treatments are life-changing! There are solutions for conditions you thought you had to live with now that you’re older. These annoyances build up over time and when you take away a few of them, quality of life is so much better. Our parents' generation accepted these conditions as part of aging, but our generation has solutions and we are happy to offer these regenerative treatments in Northern Michigan. The excitement is hard to contain!

Imagine the difference if:

Your joints moved easily enough that you could walk up and down stairs, or write and text without pain.
You could be active with tennis or golf one day and have no pain the next.
Ladies – if your overactive bladder would calm down and you could sleep for more than a couple hours.
… Or you could sneeze, laugh, and exercise without leaking.
Sex just worked like it used to (yes, for both of you!).

Question 17

Will regenerative treatments replace my prescription medication?

Accepted Answer

Sometimes. Many of our patients proudly tell us they no longer have to rely on medicine for joint pain and stiffness, or are happy to be rid of side effects from bladder control drugs they no longer need. But it depends on the condition, whether it’s new or long-term, and how well your body heals itself in response to regenerative treatment.

Question 18

What are some examples of what patients say after regenerative treatment?

Accepted Answer

“My prescription medication and cortisone shots help but I still couldn’t stand for a long time or give a good handshake without pain. And my doctor said I shouldn’t do anymore cortisone. After three PRF shots at RegenCen, I can move around like I’m 10 years younger and they last way longer than 2 months.”
“I tried medication for my bladder but it didn’t do anything. I did this MorpheusV thinking what do I have to lose and it worked! I really can’t believe it.”
“I was making the sex work because I love my husband but now I’m actually enjoying it again. FormaV made my vaginal dryness so much better. It’s more comfortable to start and I have good orgasms again.”
“The blue pill helps my erections but the PRF erection shot (the advanced P-shot or Priapus shot) made my erections more frequent, harder and longer lasting. It’s such a relief. I even get a morning woody.”
“I had breast cancer and went through immediate menopause. After I knew I was going to live, I wanted to feel better and hormones weren’t an option for me. RegenCen in Petoskey got everything working and feeling good down there -so grateful for modern medicine.”
“I’m 75 and I’m ok with some wrinkles and as a woman, I’m just not ok with all of this hair thinning. Thanks to RegenCen in Traverse City, I have better hair and more confidence.”

Question 19

Is regenerative medicine new?

Accepted Answer

No. regenerative medicine has been around for decades, but isolated in different fields. Orthopedists have used PRF injections to heal joints and tendons since the 1990s; dentists started even earlier.

We’ve practiced regenerative medicine for years in a limited way. However, technology and medical advancements have expanded the conditions we treat and the results we achieve dramatically. So we opened a new division within Cosmetic Skin & Laser Center called RegenCen throughout Michigan and Florida. And it will continue to advance and we will continue to offer more treatments.

Question 20

Is regenerative medicine safe?

Accepted Answer

Regenerative treatments have a nearly perfect safety record, with very few side effects. This is one of its greatest advantages compared to conventional medical treatment.

Dr. Gustav Lo, MD, is a family physician who practiced primary and urgent care for 30 years, operating a group of clinics with over 40,000 patient visits a year. He’s a natural skeptic, an avid reader of medical research, and a believer in the advancement of medicine. We guarantee that all of our treatments are backed by solid medical research. If we don’t do a treatment you’ve heard about and it’s in our realm, it could be “the research just isn’t there yet.” We won’t risk your safety, money or time.

Question 21

Are treatments covered by insurance?

Accepted Answer

No. Surprised? And we will spare you all the reasons.

Question 22

What conditions do you treat?

Accepted Answer

Erectile dysfunction
Osteoarthritis
Tendinitis, tennis elbow, plantar fasciitis
Urge incontinence
Stress incontinence
Overactive bladder
Vaginal atrophy
Menopausal dryness
Sexual dysfunction
Thinning hair
Dry eye

Regenerative treatments are broad. Specialists use PRF in dental work, diabetic ulcers, and wound care. Our treatments are focused on problems everyone must face: primary care regenerative conditions.

Question 23

How long do regenerative treatments last?

Accepted Answer

Most treatments last for about a year and then maintenance treatments for osteoarthritis, sexual function, bladder control, vaginal atrophy, and hair loss are scheduled in one of our MIchigan or Florida offices annually.

Question 24

Why did you open RegenCen?

Accepted Answer

Easy question. Dr. Gustav Lo is passionate about being ahead of the curve but most importantly helping people feel better. This was a natural progression. We’ve been offering feminine rejuvenation and PRF in Petoskey and Traverse City at Cosmetic Skin & Laser Center since 2017 and opened our Naples office in 2022. As regenerative treatments have evolved so has our practice. It made sense to create a separate division. Today we have 15+ locations across Michigan and Florida.

Question 25

Are you a concierge physician?

Accepted Answer

Concierge physicians are primary care physicians. Dr. Lo has 30 years of experience in primary care but now his practice is exclusively regenerative. We offer similar conveniences as a concierge physician but we recommend our patients continue with their concierge physician as primary care provider. Many concierge physicians refer to us since concierge patients tend to be focused on optimal health.
