A single checkout does not necessarily mean a single organization provides your care. Third Avenue advertises consultation, prescribing and medication fulfillment in one place, but its terms assign those jobs to different parties. Third Ave LLC operates the administrative and technology platform; MDI Medical Group PC and applicable affiliates provide healthcare; independent pharmacies dispense prescriptions. For someone considering this service, understanding those handoffs matters as much as understanding the advertised medication price.
This review follows that pathway using public documentation consulted October 19, 2026: payment and intake, clinical review, pharmacy selection, delivery and continuing support. Third Avenue documents access to compounded injectable semaglutide and tirzepatide, with medication charged separately from an annual membership. It also publishes conflicting descriptions of billing intervals, shipping and delivery-problem deadlines. Those differences do not establish that care will fail, but they do identify questions worth resolving before money changes hands or a prescription becomes nonrefundable.

Start with who is responsible for each handoff
Third Avenue’s homepage calls the business a telehealth and pharmacy platform connecting patients with licensed providers and delivering prescribed medication. Its contractual description is narrower: Third Ave LLC, a Delaware limited liability company doing business as Third Avenue, supplies administrative and technology services rather than practicing medicine. The terms explicitly say it does not make diagnosis, treatment, prescribing, medical-necessity or dispensing decisions. The convenient storefront should therefore not be mistaken for the clinical entity.
The terms assign healthcare services to MDI Medical Group PC and, where applicable, affiliated professional entities. Prescription fulfillment belongs to independent licensed dispensing pharmacies. This division provides a useful framework for questions: an account or charge problem may involve the platform, a treatment question belongs with the treating clinician, and a product-specific dispensing question may require the pharmacy. Our guide to the difference between a clinician and a platform explains why identifying these roles early is useful.
The privacy documentation draws a related boundary. Clinical intake, medical history, diagnoses, treatment decisions and medical records are collected and maintained by the independent medical group and licensed providers, distinct from Third Avenue’s business and administrative information. Prospective patients should establish how to reach the medical group and request records, rather than assuming the general support inbox is the only route. The consulted documentation did not allow independent verification of individual clinician credentials or the advertised certifications.
Checkout starts the financial clock before clinical approval
Third Avenue advertises a free, fully online assessment asking about health history, lifestyle and goals. However, its homepage says payment is collected when the order is placed, before clinical review. The seven-day membership trial also starts at checkout, not at prescription approval or medication arrival. Medication is charged during that trial. These are separate events: a free assessment and a free membership trial do not mean the initial medication order is free.
The provider promises a full refund if a clinician does not approve treatment and no prescription is issued. An unfinished intake is treated differently. Under the refund policy, the request remains pending and the money already collected stays applied to it; failing to complete the questions does not itself cancel the order or create an automatic refund entitlement. Someone who decides not to proceed should communicate that decision rather than simply leaving the intake unfinished.
The terms require users to be at least 18, or their jurisdiction’s age of majority if higher. Third Avenue advertises telehealth for eligible patients physically located in all 50 states, but specifically says not every medication or treatment is available everywhere. Location, provider licensure, pharmacy coverage, law, product availability and individual eligibility can affect access. Before checkout, it is useful to confirm availability for the actual product and location, not just rely on the nationwide headline.
Clinical review may require more than an online questionnaire
The program says a licensed clinician reviews medical history and goals and does not determine eligibility from BMI alone. That is a description of its review process, not a promise of a prescription or a substitute for product-specific assessment. The semaglutide page also says treatment is not recommended for people with a personal or family history of medullary thyroid cancer or MEN2 and directs appropriateness questions to the doctor. These statements should be discussed with the treating professional, not used as a self-screening checklist.
Although the assessment is advertised as fully online, the terms allow a provider to require synchronous audio-video communication, diagnostic testing, an in-person examination, follow-up care or additional information before prescribing or continuing treatment. The consulted documentation does not establish a mandatory laboratory panel, testing frequency, whether all testing costs are included, or a guaranteed clinical-review deadline. Preparing for a first GLP-1 consultation therefore includes asking what additional steps could be required and who arranges them.
Third Avenue also says its care team can review symptoms and response for people already prescribed a GLP-1 elsewhere, provide coaching and guide ongoing treatment strategy. That describes a possible continuity service, not an automatic prescription transfer or assurance that an existing formulation will continue unchanged. A prospective transfer patient should ask which clinician assumes responsibility, what records are needed, and whether the pharmacy, formulation or follow-up requirements would change. The public pages do not settle those details for every patient.
Separate the medication charge from access and renewal charges
The product pages identify compounded semaglutide and compounded tirzepatide, and the program lists both as prescription injections. The detailed prices are $49/month for semaglutide medication and $68/month for tirzepatide medication, each described as the same price at any dose. Both add Third Avenue Membership at $199/year after a seven-day trial. The pages also display $98/month and $135/month, respectively, without documenting clear eligibility or duration conditions for those alternative amounts; tirzepatide’s page also repeats $135/month elsewhere.
The billing interval is another unresolved issue. Monthly language appears throughout the pages, while enrollment language describes charges every 25 days. The exact quoted enrollment language explicitly states $68 every 25 days for tirzepatide; the documentation also presents monthly semaglutide pricing alongside a reported 25-day billing schedule. A 25-day renewal is not a calendar-month renewal. Neither interval establishes the exact quantity or duration of medication supplied in each order, which should be confirmed separately.
The service is cash-pay: Third Avenue says it does not submit claims to commercial insurers, Medicare, Medicaid or TRICARE. It also does not guarantee reimbursement through insurance, HSA, FSA or other benefits. Product pages say required supplies, delivery and continuing clinical oversight are covered, while enrollment says licensed-clinician review is included. These inclusions are useful, but they do not resolve unclear laboratory costs or the competing prices and intervals. Obtain the actual checkout terms in writing before authorizing recurring charges.
| Checkpoint | Documented term | What to clarify |
|---|---|---|
| Medication | Compounded injectable semaglutide: $49/month; tirzepatide: $68/month | Which displayed price applies, given alternative $98 and $135 amounts? |
| Membership | Seven-day trial from checkout, then $199/year | When will the annual charge occur relative to clinical review? |
| Renewal interval | Monthly descriptions coexist with 25-day billing language | Exact charge dates and medication supplied per order |
| Included services | Supplies, delivery and clinical oversight described as covered | Whether any required testing adds a separate charge |
| Payment channel | Cash-pay; no insurer claims submitted by Third Avenue | Any reimbursement arrangements, confirmed independently |
The pharmacy handoff determines the product you receive
Third Avenue says the exact formulation and dispensing pharmacy depend on clinical review, the patient’s state and fulfillment availability. Its terms do not guarantee a particular pharmacy and allow the dispensing pharmacy to change between orders. The consulted documentation did not name the pharmacies or establish complete compositions, concentrations, ingredient sources or documented batch testing. That leaves meaningful product questions to resolve after clinical review and before dispensing, rather than assuming the ingredient name completely identifies the preparation.
The terms allow a request to send or transfer a prescription to another pharmacy where available and legally permitted. They caution that price, availability, formulation, shipping and program services may differ, and some products may not be available elsewhere. This is a conditional option, not a promise that any pharmacy can fill the same preparation at the advertised member price. Our pharmacy-handoff questions can help organize requests for the dispensing pharmacy’s identity, contact details and product instructions.
Third Avenue discloses that compounded medicines are not FDA approved. FDA explains that these preparations do not undergo its premarket review for safety, effectiveness and quality, and recommends them when an individual’s medical needs cannot be met by an FDA-approved drug, with a prescription and state-licensed pharmacy. Nonapproval alone does not prove clinical inequivalence. It also does not establish that Third Avenue’s preparations produce results demonstrated with specific approved products. FDA approval belongs to a particular product, not this platform.
Shipping promises describe several different clocks
The homepage says orders are typically processed within 24–48 hours after prescription approval and that most arrive within three to five business days, depending on location. Tracking is emailed when the package is on its way. Processing, dispatch and arrival are different milestones; the processing estimate is not a promise that medication reaches the patient within 48 hours. The pages do not establish a guaranteed time from checkout through clinical review to arrival.
Shipping descriptions also differ. Membership advertising promises free overnight shipping on every refill, with cold shipping and plain packaging. Enrollment instead describes free discreet standard shipping. These statements may concern different circumstances, but the consulted pages do not explain a uniform rule. Ask which service applies to the initial order and subsequent refills, whether refrigeration is required for the actual preparation, and whom to contact if tracking stalls. Included shipping does not make the medication or membership free.
For delivery problems, the homepage allows seven days to report damaged, defective or incorrect products. The refund policy ordinarily requires immediate reporting, no later than 48 hours after confirmed delivery absent extraordinary circumstances, and also covers missing or potentially compromised products. Prompt contact with support avoids relying on the longer statement. Separately, FDA explicitly advises not using injectable GLP-1 medication that arrives warm or insufficiently refrigerated and contacting the provider or dispensing pharmacy. Our cold-delivery guide explains that advice.
Ongoing care is advertised, but response times are not defined
The product pages offer secure messages to the care team at any time and physician meetings during scheduled follow-ups. Membership advertising adds ongoing check-ins, treatment adjustments and care from clinicians the company describes as U.S. board-certified. These are provider claims, not independently verified credentials or a documented visit schedule. The public pages do not specify a fixed frequency of appointments, guaranteed message turnaround or guaranteed time to obtain a treatment decision.
The contact page lists support@thirdavenue.com, telephone 302-428-9872 and care-team hours Monday through Friday, 8 a.m.–8 p.m. Eastern. Being able to submit a message at any time is not the same as receiving an immediate clinical response around the clock. The terms also say communications are not monitored for emergencies. Before enrollment, ask which channel reaches the treating team, what happens outside published hours, and how administrative questions are separated from questions needing a clinician or pharmacist.
Third Avenue also advertises nutrition support, strength-training guidance, progress tracking and help managing nausea, constipation and other gastrointestinal symptoms. These offerings broaden its stated service beyond prescription fulfillment, but the pages do not establish the frequency, format or professional staffing of every component. NIDDK describes medication care as involving response, side effects, health conditions, other medicines and costs, alongside healthy eating and activity. A useful follow-up conversation should therefore involve more than confirming that the next payment processed.
Leaving the service has different boundaries at different stages
Enrollment describes medication subscriptions that renew automatically and says either the medication or membership charge can be canceled by emailing support@thirdavenue.com. The membership page says canceling before the seven-day trial ends avoids the annual membership charge. Cancellation of future charges is not the same as reversing an existing medication order, however. The documentation also does not settle whether an already charged annual membership receives a proportional refund or establish a universal minimum commitment across plans.
For an initial order or one requiring a new prescription, the refund policy generally makes the order final and nonrefundable once a licensed provider approves treatment and issues the prescription, subject to policy exceptions. That boundary can occur before pharmacy transmission, acceptance, dispensing or shipment. Refills under an existing prescription follow a different rule: they become final when submitted to or accepted for pharmacy processing. If a renewal is canceled after charging but before that processing submission, the policy says the renewal charge will be refunded.
Ordinary returns of prescription products are not accepted once they leave the dispensing pharmacy; the policy says they cannot be returned for resale, reuse, exchange or credit. Qualifying refunds are generally initiated within five to ten business days after the refund determination, with additional bank or card-issuer posting time possible. Anyone stopping service should request confirmation of both future-charge cancellation and the status of the current order. A cancellation email alone does not establish that an already-final order qualifies for reimbursement.
Questions & answers
Is Third Avenue itself my medical provider?
Not according to its terms. Third Avenue is the administrative and technology business. MDI Medical Group PC and applicable affiliated professional entities provide healthcare, while independent pharmacies dispense prescriptions. Ask for the treating clinician’s identity and the medical group’s contact and records procedures so you know where to direct clinical questions.
Does the seven-day trial include free medication?
No. Third Avenue says the trial applies only to membership and begins at checkout. Medication is charged during it. Membership then continues at $199/year unless canceled before the trial ends. The advertised $49 semaglutide and $68 tirzepatide medication prices therefore should not be read as all-inclusive prices for the entire service.
Can I choose or keep the same dispensing pharmacy?
The terms do not guarantee a particular pharmacy, and it may change. You may request a prescription be sent or transferred elsewhere where available and legally permitted, but formulation, price, shipping and program services may differ. Confirm the pharmacy for the specific order rather than assuming every refill follows the same route.
How quickly can I expect a clinical reply?
The consulted pages do not promise a response deadline. They advertise secure messaging at any time, but the contact page lists care-team hours of Monday–Friday, 8 a.m.–8 p.m. Eastern. Scheduled follow-ups are described without a fixed frequency. Ask how messages are triaged and how to reach the treating clinician, rather than interpreting message availability as continuous clinical coverage.
What if my injectable medication arrives warm or damaged?
FDA advises not using an injectable GLP-1 product that arrives warm or insufficiently refrigerated and contacting the provider or dispensing pharmacy. Third Avenue’s reporting deadlines conflict: seven days on the homepage versus ordinarily no more than 48 hours after confirmed delivery in the refund policy. Contact support immediately and ask what documentation is needed.
Will canceling before shipment guarantee a medication refund?
No. For a new prescription, the policy generally makes the order final when treatment is approved and the prescription is issued, potentially before shipment or pharmacy receipt. Refills under an existing prescription generally become final at pharmacy-processing submission or acceptance. The policy provides a refund for a charged renewal canceled before submission for processing, so the order’s precise stage matters.
Our assessment
Third Avenue documents a coordinated pathway with online intake, independent clinical review, pharmacy fulfillment, supplies, delivery and continuing support. It also identifies the separate organizations responsible for medicine and dispensing, which helps patients understand whom to contact. The principal weakness is not a complete absence of information but inconsistency at important handoffs: monthly versus 25-day billing, competing medication prices, standard versus overnight shipping, and seven-day versus 48-hour delivery-problem reporting. Before enrolling, obtain the exact recurring charges, supply quantity, dispensing pharmacy, product details and support arrangements in writing. Its nonrefundable-order boundary can arrive before shipment, making pre-purchase clarification especially valuable. The documentation supports describing Third Avenue as a platform offering access to GLP-1 care, not as evidence of verified outcomes or uniformly defined service timing.
