How to start a longevity clinic online

Most advice on how to start a longevity clinic begins with the brand, the aesthetic and the membership tiers. The better starting point is a sorting exercise. A longevity clinic sells, in practice, six things: laboratory testing, hormone therapy, peptides, NAD+, coaching, and supplements. The first four are regulated medical services. Each requires a licensed prescriber to make a patient-specific decision, a licensed pharmacy or laboratory to act on it, and a legal structure that keeps that decision with the clinician. The last two are not medical services and can be run by anyone with a website. Clinics that get into trouble blur the two sets. Clinics that scale keep them apart: the regulated four on licensed clinical infrastructure that already exists, the unregulated two in-house where the brand's own voice and margin live.

What a longevity clinic actually sells

Strip away the language and the menu is consistent from one longevity telehealth business to the next. A baseline biomarker panel, usually broad, repeated quarterly or twice a year. Hormone optimization, which for men means testosterone and for women may mean estradiol, progesterone and sometimes testosterone, with thyroid treated when a lab and a symptom justify it. Peptides, prescribed and compounded. NAD+, injected or, in its precursor forms, sold as a supplement. Sometimes a repurposed prescription drug taken off-label with a longevity rationale. Coaching on sleep, training, nutrition and stress. A supplement line, often the clinic's own label. A membership that wraps some of these together and bills monthly.

The sorting question for each item is whether a clinical decision about a specific person has to be made before the item can be delivered. Labs, hormones, peptides and NAD+ injections all answer yes. Coaching and supplements answer no, provided they stay on their side of the line. That one question determines the entity that delivers the item, the license behind it, the claims that can be made about it, and the way the money for it can flow.

Which services need a prescriber

Laboratory testing needs an ordering provider in most states. A handful of states allow direct-access testing, where a consumer orders certain panels without a clinician, but the pattern across the country is that a licensed provider orders, a CLIA-certified laboratory runs the test, and a licensed provider interprets. The interpretation is the part that matters. Explaining what a testosterone level or an ApoB result means for this patient is the practice of medicine, and a clinic that sells panels with an automated "score" and no clinician review is practicing without a license, however good the dashboard looks.

Hormone therapy needs a prescriber, a pharmacy and, for testosterone, attention to federal controlled-substance rules, since testosterone and its esters are Schedule III. The DEA's temporary telemedicine flexibilities, which allow controlled substances to be prescribed by telehealth without a prior in-person visit, run through December 31, 2026 under the extension published on December 31, 2025, and the permanent special registration rule proposed in January 2025 had not been finalized at the time of writing. A hormone therapy line built today should be built by prescribers who will hold whatever registration the final rule requires.

Peptides need a prescriber and a compounding pharmacy. A peptide sold for injection is a drug. Where it can be compounded lawfully, it is compounded by a licensed pharmacy on a patient-specific prescription after a visit. Where it cannot, no amount of "research use only" labeling makes it sellable to a patient. Which peptides fall on which side of that line has moved in 2026 and is maintained on the peptide launch page rather than restated here.

NAD+ splits in two. Injectable or infused NAD+ is a compounded prescription drug, and whether a compounding pharmacy may prepare it depends on the ingredient's status on the FDA's bulk drug substances lists at the time the prescription is written, which the pharmacy should confirm in writing before the clinic builds a product around it. Oral precursors marketed as supplements sit in the supplement category and carry that category's rules on claims. A clinic that wants both should treat them as two products from two entities, not one product in two forms.

Coaching and supplements need no license, and that is exactly why they need a fence. A coach can discuss protein targets, sleep timing and training load. A coach who tells a member to hold a testosterone dose, double a peptide, or skip a lab because the numbers looked fine is practicing medicine without a license, and the clinic that employs the coach shares the exposure. The guide on whether an operator needs a medical license covers the structure question in depth. The short version is that the founder does not need a license to own the brand, and everything that requires a license has to sit with people who hold one.

Why labs are the front door

The lab panel is the intake. It is the one product a prospect will buy before trusting the clinic with a prescription, it produces the medical indication for everything that follows, and it creates the return visit that keeps a membership alive. A clinic that opens with a hormone offer has to persuade a stranger to accept a drug. A clinic that opens with a panel has to persuade a stranger to accept a needle stick at a draw site, which is a much smaller ask, and the results conversation does the rest.

The mechanics are simple and mostly outsourced. A provider orders the panel, the patient draws at a national draw-site network or through mobile phlebotomy, and results come back to the ordering provider, who reviews them and meets the patient for a results visit. That results visit is the actual service, and it should never be replaced with an automated report. It is also where the standard of care begins. A testosterone prescription, for example, rests on confirmed low morning levels, repeated, plus symptoms, under the Endocrine Society's guideline, and a clinic whose panel and visit cannot show that has no medical indication to prescribe on.

Do not let the panel become a sales funnel in which every result leads to a prescription. The credibility of a longevity clinic rests on the members who were told they did not need testosterone.

Sourcing hormones, peptides and NAD+ lawfully

Two kinds of pharmacy matter here. A 503A pharmacy is a traditional compounding pharmacy: it prepares a medication for a named patient on a prescription from a licensed prescriber. A 503B outsourcing facility makes larger batches under manufacturing standards closer to a drug maker's and sells to clinics and hospitals for office use. For a telehealth clinic shipping to patients at home, the route is 503A, patient by patient, with the pharmacy licensed or registered as a nonresident pharmacy in every state it ships into.

For hormones, the sourcing choice is between FDA-approved products dispensed through a licensed pharmacy and compounded products, such as testosterone cream or injection, from a 503A pharmacy. Both require a prescription; the compounded route also requires a reason the approved product does not suit the patient. Testosterone's Schedule III status means the pharmacy must be DEA-registered and the prescription travels through electronic prescribing of controlled substances, EPCS, in the states that require it.

For peptides, the only lawful source is a licensed compounding pharmacy filling a prescription. Suppliers that sell peptides labeled for research use are not pharmacies, their products are not drugs a clinic may give to a patient, and in spring 2026, according to law-firm reports of the FDA's actions, the agency sent warning letters to online peptide sellers over exactly that practice. A clinic that has ever bought from such a supplier should not expect the invoice to be a defense.

For NAD+, confirm the ingredient's current status with the pharmacy before launch, get the pharmacy's stability and beyond-use data for the preparation, and settle how it ships. Injectable products need a cold chain. Tessic Health's pharmacy network dispenses at 0 percent medication markup with cold-chain home delivery on every plan, which is the arrangement a clinic should demand from any pharmacy partner: the patient pays the pharmacy's price, the clinic charges for the medicine it practices, and nobody's margin depends on the vial.

Pricing and membership

Three pricing shapes cover nearly every longevity clinic business model. Pay-as-you-go, where the patient pays for each visit, each panel and each medication separately. A monthly membership that covers visits, coaching and scheduled labs, with medication billed at cost on top. All-inclusive tiers that bundle medication into a flat fee. The first is simple and hard to grow. The third is attractive to market and dangerous to run, because bundling a drug into a fee ties the clinic's income to how much drug the member takes, and that is the pattern that state anti-kickback and fee-splitting rules and the corporate practice of medicine doctrine were written to stop.

The middle shape is the one most operators settle on. The professional corporation charges for clinical services. The management company charges for the membership experience. The pharmacy charges for the medication, at its price, with no markup passed through the clinic. Members can see what they are paying for, and the clinician's decision to prescribe or not to prescribe has no effect on anyone's revenue except the pharmacy's.

Membership brings its own law. Automatic renewal is regulated by the FTC and by state auto-renewal statutes. The FTC's 2024 click-to-cancel amendments to its Negative Option Rule were vacated by the Eighth Circuit, and on March 11, 2026 the FTC issued an advance notice of proposed rulemaking to start again, so the federal picture is unsettled; the state statutes, which generally require clear disclosure of the renewal terms, affirmative consent, and a cancellation path as easy as sign-up, are not. Build the membership to the strictest state on the map and the FTC question takes care of itself.

On the operating side, the numbers to model are the consult fee, the lab cost, the medication cost at pharmacy price, the membership price, and the share of members who renew each month. Tessic Health publishes its own terms as a reference point: $25 flat per completed consult, 0 percent medication markup, no revenue share on any plan, plans from $1,000 a month, month to month after a one-time setup fee. The entrepreneur page walks through the rest of the launch sequence.

What you can say in longevity marketing

Longevity is a claim. Under the FTC's Health Products Compliance Guidance, any claim that a product or service affects health has to be backed by competent and reliable scientific evidence before it is made, and the level of evidence rises with the strength of the claim. "Adds years to your life" has no such evidence behind it for any clinic service. "Reverses aging" is worse, because it is both unsubstantiated and, for a supplement, a claim that turns the supplement into an unapproved drug. "Optimizes your hormones" implies a result the clinic cannot promise to any individual.

Supplements can carry structure and function claims, such as "supports cellular energy metabolism", with the standard disclaimer, and cannot carry disease claims. Prescription drugs cannot be advertised for uses outside their approved labeling; a clinic can describe what its prescribers do and cannot run ads promoting an off-label longevity use of a drug as if it were established. Compounded drugs cannot be described as FDA-approved, and a compounded peptide cannot borrow the evidence of a branded product it is not. In 2026 the FDA's advertising office sent letters to telehealth and compounding operators about their promotion, as reported in the press, and those letters were about claims, not about clinical practice.

Testimonials need to reflect what a typical member experiences, or say clearly that they do not. A "biological age" or a proprietary score is a marketing device unless there is evidence behind it, and should be presented as what it is. The practical rule that keeps a longevity clinic out of trouble is to write claims about what the clinic does, which is test, review, prescribe when indicated and monitor, and not about what will happen to the member. The first kind of claim can be substantiated by the clinic's own records. The second kind almost never can.

The regulated four decide whether the clinic is legal. The unregulated two decide whether it is a business.

Questions operators ask

Does the founder need to be a physician? No. The founder owns the management company and the brand. The clinical practice sits in a physician-owned professional corporation, which is the structure the corporate practice of medicine doctrine requires in most large states, and the two are joined by a management agreement. Tessic Health drafts that structure, the MSO and the friendly PC, for the client's ownership as part of setup, so the founder owns the brand, the entity, the patients and the records from the first day.

Can a clinic sell peptides without a prescriber? No. A peptide given to a patient is a drug, and a drug reaches a patient through a prescription and a pharmacy. A clinic that sells peptides without either is a drug seller, and the FDA's 2026 warning letters were addressed to exactly those.

Can the coach adjust a hormone dose? No. Dose changes are prescribing decisions and belong to the prescriber. The coach can flag a symptom and book a visit, and the clinic's workflow should make that the easiest thing for the coach to do.

Which service should launch first? Labs, then the results visit, then whichever prescription line the results and the patient's goals justify. A clinic that launches hormones first is asking strangers to accept a drug from a brand they met last week.
