RegenHRT is RegenCen's personalized approach to hormone therapy, created around a simple idea: addressing hormonal changes requires more than treating symptoms. It requires understanding your individual physiology, establishing where your hormone levels are today, and continuing to evaluate how your body responds over time.
Offered by RegenCen through BOYD in Ann Arbor, Birmingham, and Detroit, RegenHRT combines comprehensive evaluation, individualized hormone dosing, bioidentical hormones, and ongoing medical monitoring to create a treatment plan specific to you.
Rather than following the same protocol for every patient, RegenHRT considers your lab results, symptoms, medical history, body composition, life stage, and individual goals to determine the right approach.
What is RegenHRT?
RegenHRT is RegenCen's comprehensive approach to hormone replacement therapy.
Developed under the medical leadership of Gustav Lo, MD, RegenHRT is designed to look at hormonal health as a connected system rather than treating one symptom or hormone in isolation.
Together, these principles allow your RegenCen provider to understand your starting point, develop an individualized plan, and continue refining treatment based on how your body responds.
The methodology is built around three principles:
1. Comprehensive evaluation
2. Individualized hormone dosing
3. Continued testing and optimization
Your hormone levels tell only part of the story
Hormonal health is personal.
Two people of the same age can have similar symptoms and very different hormonal profiles. Metabolism, body composition, medical history, lifestyle, baseline hormone levels, and life stage can all influence how hormones affect the body and how you respond to treatment.
That is why RegenHRT does not rely on symptoms alone.
Your provider looks at how you feel alongside objective clinical information to develop a more complete understanding of your hormonal health.
For some patients, that means recognizing hormonal changes earlier. For others, it means taking another look at hormone therapy they are already receiving and determining whether the current treatment is achieving your goals.
The RegenHRT methodology
1. Start with a comprehensive evaluation
Before deciding whether hormone therapy is appropriate, RegenHRT begins by establishing a detailed baseline.
Your evaluation may consider:
- Current symptoms and changes you have noticed
- Estrogen, progesterone, testosterone, and other relevant lab values
- Medical history and individual risk factors
- Body composition and lifestyle
- Preferred method of hormone delivery
The purpose is not simply to identify whether a hormone level falls inside or outside a reference range. It is to understand what those results mean for you.
2. Individualize hormone dosing
There is no universal hormone dose that is appropriate for every patient.
Your body's response to treatment can be influenced by your metabolism, body composition, baseline hormone levels, age, life stage, and other individual factors.
RegenHRT accounts for these differences when determining your plan.
Instead of choosing a standard protocol based primarily on age or symptoms, dosing is individualized according to you. Your provider can then evaluate your response through follow-up testing and make adjustments when appropriate.
The goal is precision rather than a one-size-fits-all approach.
3. Continue testing and optimizing
Beginning treatment is not the end of the RegenHRT process.
Your hormone needs can change, and your response provides valuable information about what your body needs.
RegenHRT uses continued lab testing and follow-up appointments to evaluate hormone levels, review how you are feeling, and determine whether your plan should be adjusted.
This creates an ongoing process:
Evaluate. Treat. Measure. Adjust.
Rather than leaving the same prescription in place indefinitely, your treatment can evolve as your physiology, health, and needs change.
Why RegenHRT focuses on physiologic hormone levels
One of the defining principles of RegenHRT is its focus on physiologic hormone levels.
A laboratory reference range can be broad, and being within that range does not tell the entire story of your hormonal health.
RegenHRT evaluates lab results in combination with symptoms, medical history, life stage, and other clinical factors. The goal is to restore hormones toward optimal physiologic levels while carefully monitoring your response.
This is also why follow-up testing is an essential part of the process. Your provider is not simply asking whether you feel different. Lab testing helps show what is actually happening in your body.
Why RegenHRT uses bioidentical hormones
RegenHRT uses bioidentical hormones, which are structurally identical to hormones naturally produced by the human body.
Depending on your individual needs, treatment may include bioidentical:
- Estradiol
- Progesterone
- Testosterone
The hormones included in your plan, their dosage, and how they are delivered are determined according to your individual clinical profile.

Hormones work as a system
Estrogen. Progesterone. Testosterone.
These hormones are often discussed separately, but they do not function separately in the body.
Changes in one hormone can affect how you feel and function alongside changes in others. Looking at only one number can sometimes miss important information.
RegenHRT evaluates the broader hormonal picture.
For women, this may mean looking beyond estrogen to understand changes in progesterone and testosterone during perimenopause, menopause, and beyond.
For men, testosterone is evaluated within the context of overall hormonal health, symptoms, body composition, medical history, and additional clinical markers.
The objective is not to treat a lab number. It is to understand how your hormonal system is functioning as a whole.

The RegenHRT approach for women
A woman's hormonal transition does not happen overnight.
Estrogen, progesterone, and testosterone can begin changing years before menopause. Because those changes may happen at different rates, symptoms and needs can vary significantly from one woman to another.
RegenHRT provides an individualized framework for evaluating hormonal health throughout:
- Perimenopause
- Menopause
- Post-menopause
Instead of waiting for a particular age or treating every woman according to the same protocol, your provider considers your current hormone levels, symptoms, medical history, risk factors, body composition, and life stage together.
Your plan can then be personalized and monitored as your hormonal needs continue to change.
The RegenHRT approach for men
Hormonal changes in men are often more gradual.
Testosterone levels can decline over time, and the effects may initially be attributed to stress, work, poor sleep, or simply getting older.
RegenHRT takes a comprehensive approach to evaluating testosterone and hormonal health in men.
Rather than making a treatment decision based on a single testosterone result, your provider considers laboratory testing alongside symptoms, medical history, body composition, lifestyle, and individual risk factors.
When testosterone therapy is appropriate, your plan is individualized and monitored over time to evaluate your response and determine whether adjustments are needed.
Your delivery method should be individualized, too
Personalization does not stop with dosage.
Different hormones and different patients may benefit from different methods of delivery. RegenHRT considers both clinical factors and patient preferences when determining how treatment should be administered.
Depending on your treatment plan, options may include:
Hormone pellet therapy
Topical creams or gels
Oral bioidentical progesterone
Vaginal hormone preparations
Other medically appropriate hormone therapies
Your provider will explain the available options and recommend an approach based on your individual needs.

Already receiving hormone therapy?
RegenHRT is not only for those beginning hormone therapy for the first time.
You may already be taking hormones but still have questions.
Are your current hormone levels where they should be?
Is your dosage right for you?
Are all relevant hormones being considered?
Is your treatment being monitored frequently enough?
Could a different delivery method be a better fit?
A RegenHRT evaluation provides an opportunity to take a fresh look at your current treatment.
Your provider can review your existing regimen, symptoms, lab results, current hormone levels, and overall clinical picture to determine whether your treatment plan should remain the same or whether another approach may be appropriate.
