The clinic, your visit, and how we work.
What to expect at a consultation, who performs the procedures, and how we decide whether biologic therapy is the right path for you.
What should I expect during my first visit? +
A 45–60 minute consultation with Dr. Glowney or Ryan Shiling, MSN, AGNP-C. We review your history and imaging, perform a focused physical exam, and walk through which therapies (if any) are appropriate for your situation. You leave with a clear plan.
Who actually performs the procedure? +
Dr. Jason Glowney performs every bone marrow aspiration, with Ryan Shiling, MSN, AGNP-C, assisting as needed, and prepares and performs PRP for his own patients in our on-site lab. Ryan provides ongoing primary care and independently manages iron infusions.
How is this different from standard orthopedic care? +
A standard orthopedic visit typically ends in one of three places: physical therapy, a cortisone injection, or a surgical referral. We add a fourth path, autologous biologic therapy, and we tell you honestly when one of the first three is the better answer for your case.
Am I a candidate for PRP or cellular therapy? +
Candidacy depends on your imaging, the stage of your condition, and your overall health, and we work it out together at your consultation. PRP tends to do best in mild to moderate joint and tendon problems. For more advanced arthritis we may talk about BMAC. When arthritis is advanced and widespread, injections are less likely to help, and we'll say so and help you find the right specialist.
How do I get started? +
- Request a consultation by phone, web form, or email: we follow up within one business day.
- Send any recent imaging (MRI, X-ray) so Dr. Glowney can review it before your visit.
- Come in for an unhurried conversation about whether biologics fit your goals.
What's the difference between PRP, BMAC, and "stem cell" therapy? +
PRP uses concentrated platelets and growth factors from your blood. BMAC uses mesenchymal stromal cell–containing material from your own bone marrow. Consistent with FDA guidance, we don't use the colloquial "stem cell therapy" framing: every therapy we offer is autologous (your own cells, minimally manipulated), not donor-derived or culture-expanded.
How long does it take to see results? +
Biological response varies by patient and condition. Many patients note progressive improvement over 4–12 weeks. We schedule functional follow-up at 6 and 12 weeks to track progress objectively, and reassess at 12–16 weeks if meaningful response hasn't emerged.
Are you part of any research studies? +
Yes. Dr. Glowney founded the Apeiron Research Center, a separate non-profit that runs IRB-approved clinical trials. Its current studies are in Parkinson's disease, and they are separate from care at the clinic. Our Clinical Trials page lists each study and its status.
02 · Cellular therapy (BMAC)
Bone marrow aspirate concentrate & MSCs.
What MSCs actually are, how they differ from what's marketed elsewhere as "stem cells," and what the procedure day looks like.
What are mesenchymal stem cells (MSCs)? +
Mesenchymal stromal cells (MSCs), often called mesenchymal stem cells, are cells found in bone marrow and other connective tissues. In the lab, scientists identify them by how they grow, the markers on their surface, and their ability to turn into bone, cartilage, or fat cells. In our clinic, MSCs are part of the bone marrow aspirate concentrate (BMAC) we inject. We use flow cytometry, a lab test that sorts cells by their surface markers, to check what our process produces.
Is this the same as a "stem cell injection" I've seen advertised? +
No. We do not perform commercially-marketed "stem cell injections" of unregulated, expanded, or donor-derived cell sources. Our cellular therapy is autologous (your own marrow), minimally manipulated, and used in a single in-clinic procedure consistent with FDA guidance.
How does this differ from PRP? +
PRP uses concentrated platelets and growth factors derived from blood. BMAC uses material from your bone marrow that also contains MSCs and other early-stage cells. We usually consider BMAC for more advanced joint disease, or when the bone under the cartilage is involved.
Is the bone marrow aspiration painful? +
Aspiration is performed in-clinic under local anesthesia, drawing from the posterior superior iliac spine (PSIS). Most patients report moderate pressure during the procedure but little sharp pain. Soreness at the harvest site for 2–5 days afterward is expected.
How long does the whole appointment take? +
Total clinic time is typically three to four hours. Most of that is biologic preparation and processing in our on-site lab, not procedure time. The aspiration itself and the image-guided delivery each take 10–30 minutes.
Why deliver to both the joint space and the subchondral bone? +
In moderate to severe joint disease, the damage often involves both the cartilage and the bone just beneath it (the subchondral bone). Many researchers now study the two as one unit. That's why, for some patients, we inject into both the joint and the bone beneath the cartilage.
What conditions do you most often consider this for? +
Most commonly evaluated:
- Moderate-to-severe knee, hip, and shoulder osteoarthritis
- Post-meniscectomy and cartilage injury
- Rotator cuff tears and labral pathology
- Avascular necrosis (early-stage)
- Recalcitrant tendinopathy where PRP has been inadequate
What can I expect after the procedure? +
Plan for 2–5 days of soreness at the harvest site and at the injection site. We provide tailored activity modification guidance and rehab milestones, with functional follow-up at 6 and 12 weeks.
Does insurance cover autologous cellular therapy? +
Most insurance plans don't cover autologous cellular therapy, and coverage varies by insurer. Boulder Biologics is a patient-pay practice. We go over the cost with you when you book, and we provide documents for HSA or FSA reimbursement.
03 · Platelet-rich plasma
PRP: preparation, procedure, and recovery.
What's actually in the syringe, how the protocol differs from kit-based PRP, and what the response curve looks like week-by-week.
How is PRP prepared in your lab? +
PRP is prepared from your own blood using a controlled, multi-step laboratory process: venous draw into anticoagulated tubes, a low-force "soft spin" to separate plasma from red cells, a higher-force "hard spin" to concentrate platelets into a pellet, and resuspension to an indication-specific platelet concentration. Baseline CBC and post-processing analysis are documented for every preparation. Our protocols follow published reporting frameworks (PAW, DEPA).
Is the PRP procedure painful? +
Most patients experience mild-to-moderate discomfort during the injection itself. Anatomic location and underlying condition affect this. Non-acidic, non-platelet-toxic local anesthetics are used for comfort, and ultrasound or fluoroscopic guidance reduces unnecessary needle passes.
How effective is PRP? +
PRP can be clinically helpful for selected musculoskeletal conditions, but effectiveness is variable. PRP is not a single standardized product, and outcomes are influenced by diagnosis, disease severity, formulation, delivery technique, rehabilitation, and individual patient biology.
Evidence is strongest for knee osteoarthritis, lateral epicondylitis (tennis elbow), and rotator cuff tendinopathy. Improvement is usually gradual, often emerging over 4–12 weeks.
How much blood is drawn? +
The amount varies by patient and indication, number of sites, severity, baseline platelet count, target concentration. Volumes are generally comparable to, and often less than, those drawn for routine laboratory testing. Collection uses sterile technique and you're monitored throughout.
Can multiple injury sites be treated during a single PRP visit? +
In selected cases, yes, but this is an individualized decision. Considerations include total PRP volume, recovery profile across sites, and whether the indications share a similar formulation. Dr. Glowney makes the call during your evaluation.
Can I drive myself home after PRP? +
Yes. PRP uses only local anesthesia, so you can drive yourself to and from the appointment. If the treated site is in a lower limb where soreness might affect pedal control, let us know in advance and we'll plan accordingly.
Should I take NSAIDs after PRP? +
We recommend avoiding NSAIDs in the early window after PRP. Inhibiting the inflammatory cascade right after the injection may blunt the very biologic response we're trying to support. Acetaminophen, ice, and elevation are acceptable for discomfort within the first few days.
When can I return to activity? +
Avoid strenuous activity for the first 24–48 hours. After that, return gradually to your rehabilitation program as outlined in your post-procedure plan. Progressive, condition-specific loading is part of how PRP outcomes are optimized, especially for tendinopathy.
What's different about Boulder Biologics PRP? +
- Protocol-driven, not kit-based: platelet concentration is adjusted to indication and your individual baseline.
- On-site, same-day processing: no shipping, no storage delays.
- Two-spin density-gradient preparation with controlled centrifugation forces.
- Leukocyte and RBC content tailored to indication rather than a one-size-fits-all formulation.
- Image-guided delivery on every procedure.
- Documentation of every preparation: baseline CBC and post-processing analysis.
04 · PRP variants
PRP+HA, PRP+protein-rich plasma, LD-PRP & hydrodissection.
Where each variant fits, why we'd reach for one over the others, and the safety considerations behind them.
Why might I be offered PRP + Hyaluronic Acid instead of PRP or HA alone? +
Because they target different drivers of OA symptoms. HA addresses the joint's mechanics (lubrication, viscoelasticity). PRP modulates the biologic environment (inflammation, signaling). Combined delivery may produce more durable improvement than either alone in knee OA, though responses vary and end-stage disease may not respond robustly to any injection.
How is the hyaluronic acid product chosen? +
HA products vary by molecular weight, crosslinking, and whether they are single- or multi-injection protocols. We choose the HA product to fit your situation. For long-standing knee arthritis we usually prefer a thicker, cross-linked product. A thinner product may suit cases where we want it to spread through the joint lining (synovium) faster.
What is PRP + Protein-Rich Plasma and how does it differ from standard PRP? +
Standard PRP focuses on platelet concentration. This protocol focuses on soluble plasma proteins, particularly alpha-2-macroglobulin (A2M) and fibrinogen, concentrated from platelet-poor plasma while retaining a controlled platelet dose. The idea is that A2M blocks a broad range of enzymes, including some that break down cartilage in osteoarthritis. It may slow that breakdown.
Why is fibrinogen sometimes useful and sometimes harmful? +
Fibrinogen can form a provisional matrix that binds and localizes growth factors, useful in controlled OA contexts. But in inflammatory joint disease, fibrinogen and fibrin degradation products may amplify inflammation. This is why we select patients carefully and avoid protein-rich preparations in inflammatory arthropathies.
When do we usually avoid the protein-rich protocol? +
Generally avoided in:
- Active inflammatory or autoimmune arthropathies (RA, psoriatic, gouty flares)
- Active infection at or near the planned injection site
- Coagulopathies or anticoagulant regimens that can't be safely managed
- Pregnancy (procedural and biologic safety not established)
How is LD-PRP (low-density PRP) different from standard PRP? +
Standard PRP is processed to a higher platelet concentration than baseline, driving a more pronounced inflammatory and proliferative response. LD-PRP is processed to a lower concentration: better suited to peri-neural and soft-tissue applications where you want some biologic signaling without the inflammatory burden.
What conditions do you use LD-PRP and hydrodissection for? +
Common contexts include:
- Peripheral nerve entrapment (carpal tunnel, ulnar at elbow, peroneal at fibular head)
- Post-surgical neuralgia and adhesion-related nerve irritation
- Sensitive soft-tissue regions where standard PRP would be too inflammatory
How long does the LD-PRP / hydrodissection procedure take? +
Plan on about two hours in the clinic. Preparing the PRP in our on-site lab takes about an hour, and the injections take 10 to 30 minutes, depending on how many areas we treat.
05 · Prolotherapy
Hypertonic-dextrose injection for ligament and tendon support.
A non-biologic injection thought to set off a local repair response. It works differently from PRP and has its own uses and schedule.
What is in a prolotherapy injection? +
A solution of hypertonic dextrose (a medical-grade sugar solution at concentrations above physiologic levels) mixed with saline. A local anesthetic may be added for comfort. It is not a biologic: there are no cells or growth factors in the syringe.
How is prolotherapy different from PRP? +
PRP is a biologic made from your own blood: concentrated platelets and growth factors. Prolotherapy is not a biologic. The dextrose irritates the tissue on purpose, which sets off an inflammatory response that is thought to promote collagen growth. The two work differently and are often used for different problems.
How many injections will I need? +
Improvement, when it occurs, is typically gradual and often requires a series of injections spaced over weeks to months. The exact cadence depends on the structure being treated and your response. Most protocols involve 3–6 sessions, with reassessment between.
Is prolotherapy painful? +
Most patients tolerate prolotherapy well, especially with local anesthesia. Mild-to-moderate soreness for several days after the injection is common, and is part of the intended inflammatory response.
When can I return to activity? +
Most patients can resume light activity the same day. We recommend avoiding strenuous activity for 24–72 hours, then a gradual return as guided by your post-procedure plan and any concurrent rehabilitation.
Does insurance cover prolotherapy? +
Prolotherapy is generally not covered by commercial insurance plans or Medicare for musculoskeletal indications. We discuss the cost with you when you book your service and supply HSA/FSA reimbursement documentation where applicable.
06 · Longevity medicine
Healthspan, biological aging, and HRT.
How longevity care differs from an annual physical, what hormone replacement decisions look like, and how long a program runs.
How is this different from a regular annual physical? +
An annual physical screens for disease you may already have. A longevity assessment looks further ahead. It estimates your biological age, tracks markers across several body systems (epigenetic, heart and metabolic, brain, and mitochondrial), and looks for the factors you can change. We then build a plan aimed at those factors.
Do you prescribe hormone replacement therapy (HRT)? +
Yes, when it's right for you. We start with a full workup, including your hormone levels and metabolism, heart risk, family history, and goals, and decide together. If you start HRT, we see you for regular follow-up.
Do you offer peptide therapy? +
We discuss peptide options where the evidence base and regulatory status support their use. We do not promote unregulated or research-only compounds for general "optimization."
How long is a longevity program? +
Most clients begin with a comprehensive assessment, followed by 3–6 months of active optimization with quarterly follow-up. Long-term care is structured around an annual cadence with interval testing.
Is longevity care covered by insurance? +
No. Longevity consultations and testing are not covered by insurance; Boulder Biologics is a patient-pay practice. We discuss the cost with you when you book your service and supply HSA/FSA documentation where applicable.
Can I do both orthopedic and longevity care here? +
Yes, and many of our patients do. Staying strong and mobile is part of aging well, so the two often overlap.
07 · Insurance & billing
Pricing, payment, and reimbursement.
The honest summary: most biologic and longevity services are self-pay, and we provide documentation for HSA/FSA reimbursement.
Does insurance cover orthobiologic therapy? +
Most plans (commercial and Medicare) currently do not cover autologous biologic procedures. Boulder Biologics is a patient-pay practice, and we go over the cost with you when you book.
Can I use HSA or FSA funds? +
In most cases, yes. We provide itemized documents for HSA or FSA claims. Your plan administrator decides what your account will cover.
What does a PRP or BMAC procedure cost? +
Pricing depends on the joint, the number of sites, and the specific formulation (e.g., standard PRP, PRP + HA, BMAC). We discuss the cost with you when you book your service, so there are no surprises at the time of the procedure.
Still wondering
If your question isn't here, ask Dr. Glowney.
A 45–60 minute consultation is the surest way to find out whether biologic or longevity care fits your situation. We answer honestly, including when the answer is "not right now."
