MEDVi, Ro and PlexusDx are three different ways to access GLP-1 medication, not three prices for the same thing. MEDVi bundles compounded semaglutide injection into one program charge: $179 for a new patient's first month, then $299 per billing cycle at refill as displayed September 22, 2026. Ro sells branded Wegovy® and Zepbound® only, with a $149/mo membership billed separately from dose-tiered medication that starts at $149/mo for the Wegovy® pill. PlexusDx sells compounded medication at one flat price with no membership: Semaglutide Injection $189/mo and Tirzepatide Injection $289/mo month-to-month. Which is right depends on whether you want branded or compounded medication and how you prefer to be billed.

Three-provider access pathways

MEDVi is a telehealth platform; prescriptions are issued by licensed providers in its network and filled by compounding pharmacies it names on its page (Triad Rx, RedRock Pharmacy, Beaker Pharmacy & Compounding). Ro is a telehealth membership whose current weight-loss page routes to branded pharmacy products. PlexusDx connects you to an independent network of U.S.-licensed clinicians through a state-licensed telehealth platform, with medication prepared by state-licensed 503A compounding pharmacies. PlexusDx serves eligible adults in all 50 states; five states require a scheduled video consultation. Neither MEDVi nor Ro publishes a state list on the pages we checked; MEDVi's terms direct state questions to help@medvi.org.

Medication identity and route

This is the first filter. MEDVi's compounded menu is semaglutide injection, tirzepatide injection and a daily compounded semaglutide tablet, plus a branded Wegovy® and Zepbound® pathway. Ro's page lists branded Wegovy® pill, Wegovy® pen and Zepbound® KwikPen, with no compounded option shown. PlexusDx offers compounded semaglutide and tirzepatide as weekly injections or daily tablets, plus a Microdose GLP-1 Protocol. Compounded semaglutide and tirzepatide are not FDA-approved drug products and are not the same as Wegovy®, Ozempic®, Zepbound® or Mounjaro®; a compounded tablet is not the FDA-approved oral product. Brand-drug trial results do not establish identical outcomes for a compounded formulation. See the FDA's statement on unapproved GLP-1 drugs.

Membership, medication, and total cost

Rows below are grouped by medication and route so compounded and branded products are never on one line. Ro's figures are two separate charges; MEDVi's and PlexusDx's compounded figures include medication.

PlexusDx publishes this comparison and offers one of the programs discussed. Information is based on the sources and dates shown.

Checked September 22, 2026 from each provider's official pages and PlexusDx product pages. MEDVi's ongoing month-to-month rates ($299 semaglutide, $399 tirzepatide) were verified September 22, 2026; confirm current pricing in its offer. Ro also lists the Wegovy® pen at $349/mo plus membership. PlexusDx 3- and 6-month commitment tiers are shown separately below.

Worked totals, same product only. A new MEDVi semaglutide patient pays intro plus (n − 1) refills: $777 for three cycles, $1,674 for six and $3,468 for twelve, assuming the $299 refill holds and each cycle bills once. PlexusDx Semaglutide Injection month-to-month is $567 for three cycles, $1,134 for six and $2,268 for twelve. For Ro there is no like-for-like row, because Ro sells branded medication with a separate membership; add the $149/mo membership to the dose-tier medication price for each month you stay enrolled. For compounded tirzepatide injection, MEDVi's ongoing rate of $399 per cycle (verified September 22, 2026) gives refill-only totals of $1,197 for three cycles, $2,394 for six and $4,788 for twelve; MEDVi's tirzepatide first-month offer is not published, so no new-patient total is computed. PlexusDx Tirzepatide Injection month-to-month is $289/mo versus MEDVi's ongoing $399/mo, $110 a month less at PlexusDx, or $3,468 versus $4,788 over twelve billing cycles at the ongoing rates. MEDVi offers 3-, 6- and 12-month bundles; their rates appear in its signup flow and are not published here.

PlexusDx commitment tiers, labeled as such: Semaglutide Injection is an advertised $169/mo on a 3-month commitment (commitment total $507) and $149/mo on a 6-month commitment (commitment total $894). Tirzepatide Injection is $269/mo on a 3-month commitment ($807) and $249/mo on a 6-month commitment ($1,494). The payment schedule and any refund terms for a multi-month plan are shown at checkout. The full MEDVi breakdown is in MEDVi Cost: Semaglutide, Tirzepatide, Membership, and Plan Prices.

Cash-pay versus insurance process

All three publish self-pay prices. MEDVi states "no insurance required" and accepts HSA/FSA. Ro's branded prices are self-pay medication charges alongside its membership; whether your plan would cover a branded product is between you and your insurer, and the Ro page we checked does not describe an insurance-assistance service. PlexusDx is self-pay, charges $0 until your provider approves a prescription, and does not bill insurance. If insurance coverage of a branded drug is your goal, confirm with the provider and your plan before paying any membership.

Commitment and support

MEDVi is cancel-anytime with a request at least 72 hours before the next billing date; no refund for the month in which you cancel; full refund only within the first 72 hours without services or on medical disqualification. Its included services are notable: free dietitian visits and care coaching, unlimited 24/7 support, a metabolic report and free shipping. Ro requires cancellation 48 hours before renewal and its membership fee is non-refundable once paid. PlexusDx month-to-month plans cancel anytime with no long-term contract, and the monthly price covers the provider visit, prescription, medication and shipping. Third-party MEDVi customer reviews describe mixed billing and support experiences; those are self-reported.

Decision matrix

In every case, a licensed clinician decides whether a medication is appropriate; no platform guarantees a prescription. For the two-way PlexusDx comparison, see MEDVi vs PlexusDx: Compare GLP-1 Prices, Plans, and Support, or compare current plans on the Weight Management Protocols collection.

A note on genetics (optional)

PlexusDx offers compounded semaglutide and tirzepatide through its Weight Management Protocols. Separately, and only if it interests you, the GLP-1 & Peptide Pathways Genetic Test ($298) analyzes 14 pathways, 49 peptides, 150+ genetic insights, including variants in FTO, MC4R and TCF7L2 that relate to appetite and glucose-handling pathways. It does not predict how you will respond to any medication and does not tell you which drug, dose or provider is right for you; it is context for a conversation with your clinician. Test before you invest, and treat genetics as a guide, not a guarantee.

This article is educational. PlexusDx is not affiliated with MEDVi and has no commercial relationship with the companies discussed. PlexusDx offers compounded semaglutide and tirzepatide through its own Weight Management Protocols; this article compares approaches in the GLP-1 telehealth space. The GLP-1 & Peptide Pathways Genetic Test analyzes how your genes influence peptide-related biological pathways. It does not predict response to any specific medication and does not recommend, prescribe, or determine which peptides you should use. Consult a qualified healthcare provider before beginning any peptide protocol. Compounded semaglutide and tirzepatide are not FDA-approved drug products; they are prepared by state-licensed compounding pharmacies under federal compounding rules and are not the same as Wegovy®, Ozempic®, Zepbound® or Mounjaro®. Zepbound® and Mounjaro® are registered trademarks of Eli Lilly and Company; Wegovy® and Ozempic® are registered trademarks of Novo Nordisk A/S.

Frequently Asked Questions

Which is cheapest: MEDVi, Ro or PlexusDx?

There is no single answer because the products differ. For compounded semaglutide injection, MEDVi is $179 the first month then $299 per cycle as displayed September 22, 2026, and PlexusDx is $189 per month flat. Ro sells branded Wegovy and Zepbound only, with a $149 monthly membership plus dose-tiered medication. Compare within the same medication and route.

Does Ro offer compounded semaglutide or tirzepatide?

Not on the weight-loss page checked September 22, 2026. Ro's lineup is branded Wegovy pill, Wegovy pen and Zepbound KwikPen, priced by dose and billed in addition to its membership. MEDVi and PlexusDx both offer compounded semaglutide and tirzepatide: PlexusDx Tirzepatide Injection is $289 per month month-to-month versus MEDVi's ongoing month-to-month $399, verified September 22, 2026, and MEDVi shows its tirzepatide first-month offer after the questionnaire.

What does the Ro membership fee cover?

Ro's Body membership is $149 per month recurring, with a $39 first month, and it is billed separately from medication. It covers the clinical relationship, not the drug. The published branded medication prices, such as the Zepbound KwikPen at $299 to $449 per month by dose, are added on top. Ro's membership fee is non-refundable once paid.

Does MEDVi charge a membership fee?

For its compounded programs MEDVi states that medication is included in the program cost and that there is no membership or hidden fees, as of September 22, 2026. Its branded Wegovy and Zepbound pathway is priced differently, as a monthly membership plus a separately billed medication cost. Confirm the branded medication amount in MEDVi's offer before enrolling.

How do commitment terms differ across the three?

MEDVi requires a cancellation request at least 72 hours before the next billing date and does not refund the month you cancel. Ro requires cancellation 48 hours before renewal. PlexusDx month-to-month plans cancel anytime with no long-term contract, and PlexusDx charges nothing until a provider approves a prescription. Multi-month plans at each provider carry their own terms shown at checkout.
