Gyms, fitness studios, and recovery lounges are adding medical weight-loss programs — GLP-1 injections, B12, peptide protocols, IV hydration. The demand is real and the margin is better than membership revenue. The question owners ask is simple: can we actually do this?
The short answer is yes, but not directly. The gym cannot prescribe. A separate clinical entity does, and the gym contracts with it. Getting that separation right is the entire compliance question.
Why the gym itself cannot own the medical side
Most states apply a doctrine called the corporate practice of medicine. In broad terms it says that a business owned by non-licensed people cannot employ providers to practice medicine, cannot own a medical practice, and cannot control clinical decisions. The purpose is to keep treatment decisions with the clinician rather than with whoever owns the company.
A prescription for semaglutide is the practice of medicine. So is ordering labs, and so is an IV infusion. If your LLC owns the gym and you are not a licensed provider, that LLC generally cannot be the entity delivering those services.
This catches operators off guard because the fitness side has almost no licensing friction. Personal training, nutrition coaching, recovery services, and supplements sit outside medical regulation in most states. The moment a prescription or an infusion enters the offering, an entirely different rulebook applies.
The structure that makes it work
The standard arrangement has three parts:
- A professional corporation (PC) owned by a licensed physician. The PC is the entity that delivers clinical care. It employs or contracts the providers, holds the patient records, and owns the clinical decisions.
- A management services organization (MSO) — which can be owned by non-licensed operators. The MSO provides everything non-clinical: space, equipment, scheduling, marketing, billing support, staffing for non-clinical roles, technology.
- A management services agreement (MSA) between them, setting out what the MSO provides and what it is paid.
Your gym, or an affiliate of it, is on the MSO side. Patients are patients of the PC. Members are members of the gym. The same person may be both, and that is fine — but the records, the consents, and the clinical authority sit with the PC.
Who evaluates and who prescribes
Before any patient receives a prescription weight-loss medication, a licensed provider — a physician, nurse practitioner, or physician assistant — has to evaluate them. That evaluation is commonly called a good faith exam, and it has to be performed by someone licensed in the state where the patient is physically located.
Your trainers cannot do this. Your front desk cannot do this. A form the member fills out on an iPad is intake, not an exam.
What the provider is assessing is whether the treatment is appropriate for this person: BMI and weight-related conditions, thyroid and pancreatic history, family history of medullary thyroid carcinoma, current medications, pregnancy status, prior bariatric surgery, and so on. Some members will not be candidates. A structure that never produces a “no” is not performing real evaluations.
Where the line between fitness and medicine sits
| Offering | Typically fitness | Requires clinical entity |
|---|---|---|
| Personal training, programming | Yes | No |
| General nutrition coaching | Yes | No |
| Retail supplements | Yes | No |
| Body composition scanning | Usually | Depends on claims made |
| Blood draws and lab panels | No | Yes — requires an order |
| IV hydration and vitamin infusions | No | Yes |
| B12 and lipotropic injections | No | Yes |
| GLP-1 weight-loss prescriptions | No | Yes |
| Hormone therapy | No | Yes |
The distinction is not how invasive something feels. It is whether a licensed provider has to order it. A vitamin infusion feels wellness-adjacent; it still requires an order and a provider willing to stand behind it.
Labs, and why in-house draws change the model
Weight-management and hormone programs run better with baseline and follow-up labs. Sending members to an outside draw site introduces a drop-off point — a meaningful share never go.
Drawing on site removes that friction, but it adds requirements: someone qualified to draw, an ordering provider, a reference lab relationship, specimen handling and courier logistics, and results routed back into the clinical record where the provider can act on them. That is an operational build, not a vendor signup.
What operators get wrong
- Running it through the gym LLC. The most common error, and the hardest to unwind later.
- Paying the physician a share of program revenue. Depending on the state and the arrangement, revenue-share and fee-splitting arrangements with clinicians create real exposure. Management fees are normally structured as fair market value for services actually provided.
- A medical director in name only. A physician who signs an agreement, never reviews a protocol, and never sees a chart is not oversight. It is a signature.
- Marketing that promises outcomes. “Lose 20 pounds guaranteed” is an advertising problem and a clinical one.
- Treating every state the same. Supervision rules, NP authority, and telehealth standards differ. A structure that works in one state may not transfer.
What this looks like when it is built properly
MDside builds and operates the clinical side so the fitness business can stay a fitness business. We form the professional corporation in each state you operate in, place the licensed providers, write and maintain the clinical protocols, run the evaluation and prescribing workflow on software we own, and integrate lab draws at your location.
You keep your brand, your members, and your operations. The clinical entity carries the clinical responsibility. See what is included, or read about the operators we work with.
Frequently asked questions
Can my gym prescribe semaglutide?
The gym entity itself generally cannot. A physician-owned professional corporation, with providers licensed in the patient’s state, prescribes; the gym contracts with that entity for space and administrative services.
Do I need to be a physician to open a medical weight-loss program?
No. That is the point of the PC-MSO structure — it lets a non-licensed operator run the business while a licensed entity delivers the care.
Can a personal trainer administer an injection?
No. Administration is a clinical act performed by appropriately licensed staff under an order and a written protocol. Scope varies by state, but personal training certification does not confer it.
How long does it take to set up?
It depends primarily on the states involved and how quickly entity formation and licensing move in each. Multi-state footprints take longer than a single location. Anyone quoting a fixed timeline without asking which states you are in is guessing.
Can I use one structure across several locations in different states?
Usually you maintain one MSO and a separate professional corporation per state, all operating under the same management agreements. That is how multi-state operators expand without rebuilding from scratch each time.
