Question 1

Is this the same as concierge medicine?

Accepted Answer

No, but we do offer the same high-touch, personalized care—without the monthly fees. Our care is proactive and tailored, with more time and attention than typical primary care.

Question 2

Do you prescribe semaglutide or GLP-1s for weight loss?

Accepted Answer

Yes, when appropriate. Semaglutide is one of our most requested and effective tools for sustainable weight loss in men and women over 40.

Question 3

Do you offer hormone therapy near me?

Accepted Answer

Yes! Looking for hormone testing near me? RegenCen provides hormone testing and bioidentical hormone therapy at our locations across Michigan and Florida. Book at the clinic closest to you.

Question 4

How do I know which treatments are right for me?

Accepted Answer

You don’t have to! That’s what your consultation is for. Your provider will guide you based on symptoms, lab results, and your long-term health goals.

Question 5

Can I see you if I’m already on hormone treatment elsewhere?

Accepted Answer

Absolutely. We frequently help patients fine-tune or transition their current treatment to achieve better outcomes and symptom relief.

Question 6

What’s the difference between RegenCen and my primary care doctor?

Accepted Answer

We focus on root causes, proactive care, and hormone optimization—something most traditional practices aren’t equipped to manage. Expect deeper testing and more personalized plans.

Question 7

Is RegenCen covered by insurance?

Accepted Answer

RegenCen is a cash-pay clinic, allowing us to spend more time with you and offer innovative care without insurance limitations. HSA/FSA accounts are often applicable.

Question 8

What’s the difference between PRF and PRP for joint pain or hair loss?

Accepted Answer

PRF (platelet-rich fibrin) is an advanced form of PRP. It slowly releases growth factors over time for better tissue healing, improved outcomes, and longer-lasting results.

Question 9

What if I feel "off" but don’t know what to ask for?

Accepted Answer

That’s exactly why we’re here. Our complimentary mini consultation is designed to listen, assess symptoms, and guide you toward what’s most helpful—whether it’s hormone therapy, weight loss support, or longevity-focused care.

Question 10

Is RegenCen affiliated with CSLC?

Accepted Answer

Yes, RegenCen is the regenerative medicine division of Cosmetic Skin & Laser Center (CSLC), which has been a trusted name in aesthetic and wellness care for nearly 25 years.

Question 11

Who founded RegenCen?

Accepted Answer

RegenCen was co-founded by Dr. Gustav Lo and Courtney Lo—bringing together decades of medical experience and patient-centered innovation. Under their leadership, a certified team of hormone and regenerative medicine specialists delivers personalized care to help patients feel better, age stronger, and thrive through midlife and beyond.

Question 12

Do you treat both men and women?

Accepted Answer

Yes, our clinic is designed to help women navigate hormone changes during perimenopause and menopause, and men over 40 who are experiencing low testosterone, fatigue, or performance concerns.

Question 13

What treatments do you offer for anti-aging?

Accepted Answer

From hormone optimization and NAD+ therapy to medical weight loss and joint rejuvenation, our approach targets root causes of aging so you can stay strong, sharp, and energetic.

Question 14

Is this a long-term program or one-time treatment?

Accepted Answer

It’s up to you. Most patients benefit from long-term optimization, but you can begin with one goal or treatment and expand based on your needs.

Question 15

How do I know if I have low testosterone?

Accepted Answer

Common signs of low testosterone include fatigue, decreased muscle mass, reduced libido, difficulty concentrating, weight gain, and mood changes. If you’re a man over 40 and experiencing these symptoms, it’s worth testing your hormone levels. We offer comprehensive lab work and hormone testing to assess your testosterone and related hormone levels.

Question 16

What does testosterone therapy involve?

Accepted Answer

Testosterone therapy at RegenCen is customized to your body and goals. Treatment options include topical gels or creams and testosterone pellets. We base your care on detailed labs, your symptoms, and lifestyle preferences, with regular follow-ups to ensure optimal results and safety.

Question 17

Is testosterone therapy safe?

Accepted Answer

When supervised by a certified medical provider, testosterone therapy is safe and effective. At RegenCen, your treatment is overseen by experienced providers who monitor your labs and response to ensure your hormone levels stay within a healthy, therapeutic range.

Question 18

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 19

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 20

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 21

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 22

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 23

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 24

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 25

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 26

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 27

Are treatments covered by insurance?

Accepted Answer

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

Question 28

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 29

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 30

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 31

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.
