MEDVi vs PlexusDx: GLP-1 prices and programs compared
Part of our GLP-1 provider research: See how every compounded tirzepatide provider compares →
MEDVi's ongoing rate is $299 a month for semaglutide, after a $159 promotional first month that then reverts. PlexusDx charges one flat, all-inclusive $189 every month, with no step-up. MEDVi's edges are that cheaper first month and its deepest 48-week prepaid bundle; PlexusDx's are flat pricing, commitment discounts, and a cheaper oral option.
Green marks the better result on that row, for either program.

MEDVi's ongoing rate is $299/$399 after a $159/$259 promotional first month. PlexusDx is a flat $189/$289 month-to-month, with 3- and 6-month rates down to $149/$249.
Month-to-month, PlexusDx is about $110 less on both compounds every month after the first, because MEDVi's promotional first month reverts to a $299/$399 ongoing rate. What should decide it: whether you want a flat rate that never steps up, a cheaper oral option, and pricing you can see before a questionnaire, or MEDVi's lower entry month, its generous included coaching, and a 48-week prepaid tirzepatide bundle that dips just below our six-month rate.
- The first month matters most. MEDVi's promotional first charge is $159 semaglutide or $259 tirzepatide, about $30 below our $189 and $289, before it reverts to $299/$399 ongoing.
- You'll prepay a long term for the deepest rate. MEDVi's 48-week tirzepatide bundle was $2,859 at checkout, about $238/month, below our six-month $249; its semaglutide bundle works out to about $149/month, a tie with our six-month rate.
- You value generous included support. MEDVi bundles free care coaching, a free dietitian visit, and unlimited doctor calls, plus Klarna 0% financing on multi-month plans.
- You want a rate that never steps up. $189/$289 is one flat, all-inclusive charge covering the consult, prescription, medication and shipping, with no promotional first month that later reverts to a higher rate.
- You want a lower rate for committing. $169/$269 on 3 months or $149/$249 on 6, with no 48-week prepayment required to reach our floor.
- You want a cheaper oral option, or more formats. MEDVi offers an oral tablet too, but it runs about $70 over its injection; PlexusDx's oral costs less, and we also add the GLP-Squared combination and a $129 microdose.
- You want optional genetics and pharmacist support. An optional genetics add-on ($298, or $99 for program members) and a free check-in with a Doctor of Pharmacy. The test does not select or predict a medication — your provider decides.

Our own opinion scoring by the PlexusDx editorial team against each program's July 2026 captured pricing and published offerings, not customer ratings. MEDVi scores higher on its first month and on the depth of its 48-week prepaid savings. We publish this comparison and are one of its two programs.
How much do MEDVi and PlexusDx cost per month and per year? (Verified July 2026)
MEDVi's ongoing rate is $299/month for semaglutide and $399 for tirzepatide, after a $159/$259 promotional first month. PlexusDx is a flat $189/$289 month-to-month — $169/$269 on 3 months, $149/$249 on 6.
Month-to-month, PlexusDx is about $110/month less on both compounds — and it stays that way, while MEDVi's $159/$259 is a promotional first month that reverts to $299/$399. MEDVi wins two ways worth naming: its first month is about $30 cheaper, and its deepest 48-week prepaid bundle reaches about $238/month for tirzepatide (below our 6-month $249) and about $149/month for semaglutide (a tie with our 6-month rate).
| Semaglutide — by term | PlexusDx | MEDVi | Difference |
|---|---|---|---|
| Month-to-month (ongoing) | $189/mo, one charge | $299/mo ongoing | PlexusDx −$110/mo |
| First month | $189 (same as every month) | $159 promotional, then reverts | MEDVi −$30 in month 1 |
| Deepest prepaid | $149/mo (6-month rate) | ≈$149/mo (48-week bundle ≈$1,788) | Tie ≈$149/mo — MEDVi on a 48-week term |
| Cost over 12 months | $2,268 M-t-M · $1,788 at the 6-mo rate | ≈$3,448 monthly plan · $1,788 deepest prepaid | PlexusDx −$1,180/yr on the monthly plan; a tie at the deepest prepaid |

Running totals: who's cheaper, and when
On the monthly plan, PlexusDx costs less every month after the first, because MEDVi's promotional month reverts to a higher ongoing rate. At the deepest prepaid tier, MEDVi closes the gap — a tie on semaglutide and a slight edge on tirzepatide — but only by prepaying 48 weeks.
- Monthly plan, semaglutide, year one: MEDVi ≈$3,448 ($159 first month + 11 × $299) vs PlexusDx $2,268 (12 × $189) — PlexusDx about $1,180 cheaper.
- Deepest prepaid, semaglutide, year one: MEDVi $1,788 (48-week bundle) vs PlexusDx $1,788 (6-month rate ×12) — a tie at about $149/month; MEDVi's needs one 48-week prepayment.
- Deepest prepaid, tirzepatide, year one: MEDVi $2,859 (48-week bundle) vs PlexusDx $2,988 (6-month rate ×12) — MEDVi about $129 cheaper at its deepest tier, on a 48-week commitment.
How MEDVi's billing works
- Auto-renewing subscription: the monthly plan enrolls you in an auto-renewing subscription, charged "at the specified recurring intervals until I cancel."
- Supply label, not a billing cycle: the monthly plan ships a "4 Week Supply" — how much medication arrives per shipment, not a stated billing interval; MEDVi describes the plan as monthly and auto-renewing.
- No membership fee: MEDVi charges no separate membership — parity with PlexusDx, which also has none.
- Multi-month bundles are prepaid: paid upfront or through Klarna 0% financing over 12 months; MEDVi states multi-month packages "will not be refunded for unused medication or remaining months."
- The first month is promotional: MEDVi's $159/$259 first-month price is a limited promotional discount that reverts to the $299/$399 ongoing monthly rate.
MEDVi billing language quoted verbatim from its checkout order summaries and plan-selection screens, captured July 20, 2026.
MEDVi figures recorded by completing its signup to two checkout order summaries (19 dated captures, July 20, 2026): the semaglutide 3-month bundle read $475, the tirzepatide 12-month bundle $2,859. PlexusDx figures are our published all-inclusive rates; paired figures list semaglutide first, tirzepatide second. Prices change often — check both sites.
One flat price — the same every month it renews
Semaglutide $189/mo, tirzepatide $289/mo, all-inclusive — no promotional first month that later steps up, and down to $149/$249 on a 6-month rate. A licensed provider reviews your intake before anything is prescribed.
How do PlexusDx and MEDVi compare, feature by feature?
Both are cash-pay compounded-GLP-1 programs selling semaglutide and tirzepatide, each in injection and oral forms. PlexusDx bills one flat month-to-month charge; MEDVi runs a promotional first month that reverts to a higher ongoing rate, with deeper prepaid bundles.

When is MEDVi the better choice?
MEDVi is the better pick if the first month's cost matters most, if you'll prepay a full 48 weeks for its deepest rate, or if you want its included dietitian and coaching.
- Its first month is cheaper than ours. MEDVi's promotional first month is $159 for semaglutide and $259 for tirzepatide, versus PlexusDx's $189 and $289 — about $30 less in month one, before it reverts to $299/$399.
- Its deepest prepaid tier can beat ours. MEDVi's 48-week bundles work out to about $149/month semaglutide and $238/month tirzepatide (its 12-month tirzepatide total was $2,859 at checkout) — at or below our 6-month rate, on a full prepaid commitment.
- Generous inclusions. A free dietitian visit, free care coaching, and "UNLIMITED doctor calls 7 days a week" are bundled into every plan.
- It offers Klarna 0% financing to spread multi-month plans over 12 months.
When is PlexusDx the better choice?
PlexusDx is the better pick if you want a flat rate with no promo cliff, a lower ongoing price, more ways to take the medication, or the genetics and pharmacist layer.
- Flat month-to-month, no promo cliff. $189 semaglutide and $289 tirzepatide is the same every month — no discounted first month that steps up to $299/$399 afterward.
- A lower ongoing rate. On the sustained month-to-month rate PlexusDx is $110/month below MEDVi's $299/$399 — every month after the first.
- More ways to take it — and a cheaper oral. The GLP-Squared combination and a $129 microdose are formats MEDVi doesn't offer; MEDVi has an oral tablet too, but it runs about $70 over its injection, and PlexusDx's oral costs less.
- Published pricing, plus genetics and a pharmacist. Every tier is shown before intake, alongside the optional Precision Peptide Genetic Test ($298, or $99 for program members) and a free check-in with Dr. Jayden Lee, PharmD. It does not select or predict a medication; your provider decides.
What does PlexusDx offer that MEDVi doesn't?
Both programs offer an oral option alongside injections, so oral isn't the dividing line — but PlexusDx's oral costs less than MEDVi's, and PlexusDx adds two formats MEDVi doesn't: the GLP-Squared combination protocol and a $129 microdose.
- Injection is where PlexusDx undercuts MEDVi. Semaglutide injection is $189/month month-to-month — $110 under MEDVi's $299 ongoing rate.
- Both offer an oral tablet — ours costs less. MEDVi's tablet runs about $70 over its own injection; PlexusDx's oral runs below MEDVi's on the ongoing rate.
- Within PlexusDx, oral is a premium over injection — oral semaglutide is $289/month month-to-month, a no-injection format priced above our own injection, offered alongside it rather than instead of it.
PlexusDx GLP-1 formats — published pricing, month-to-month first
- Semaglutide injection — $189/mo month-to-month · $169 (3-mo) · $149 (6-mo)
- Tirzepatide injection — $289/mo month-to-month · $269 (3-mo) · $249 (6-mo)
- Oral semaglutide — $289/mo month-to-month · $269 (3-mo) · $249 (6-mo) — no-injection format, a premium not a saving
- Oral tirzepatide — $349/mo month-to-month · $299 (3-mo) · $279 (6-mo)
- GLP-Squared combination protocol — $289/mo month-to-month · $249 (3-mo)
- Microdose GLP-1 — $129/mo flat, a lower-cost entry point
How does MEDVi pricing work?
MEDVi shows a promotional first month — $159 semaglutide / $259 tirzepatide — that reverts to an ongoing $299 / $399 month-to-month. Its deepest 12-month prepaid bundles run lower, with no membership fee.
MEDVi describes its billing in its own checkout terms. In its own words, enrolling authorizes:
- an "auto-renewing subscription," charged "at the specified recurring intervals until I cancel";
- a "binding, final transaction," with refunds "governed solely by the MEDVi Refund Policy";
- "cancellation only stops future charges"; and
- "multi-month packages will not be refunded for unused medication or remaining months."
How does PlexusDx pricing work?
PlexusDx charges one flat, all-inclusive price per medication, the same at every dose — semaglutide $189/mo and tirzepatide $289/mo month-to-month, dropping to $149/$249 on a 6-month plan.
Where PlexusDx holds its rate is over time — one flat charge that never steps up. Over a full year the flat rate outruns MEDVi's promo-then-ongoing structure; on the deepest prepaid tiers the two run close.
- Semaglutide, monthly plan, year one: $2,268 at PlexusDx's flat $189 vs ≈$3,448 at MEDVi's ongoing rate ($159 first month + 11 × $299) — about $1,180 less.
- Tirzepatide, monthly plan, year one: $3,468 vs ≈$4,648 ($259 first month + 11 × $399) — about $1,180 less.
- Deepest prepaid, semaglutide, year one: a tie — both ≈$1,788; MEDVi's needs one 48-week prepayment.
- Deepest prepaid, tirzepatide, year one: MEDVi ≈$129 lower ($2,859 vs $2,988), on a 48-week commitment.
How does compounded GLP-1 telehealth work?
You complete an online intake, a licensed provider reviews it, and if treatment is appropriate a state-licensed 503A pharmacy prepares and ships your medication — no in-person visit required.
Both PlexusDx and MEDVi follow this cash-pay telehealth model. You answer a health questionnaire online; a licensed U.S. provider reviews your history and, if appropriate, writes a prescription. A 503A compounding pharmacy — a state-licensed facility that prepares medication for an individual patient based on a valid prescription — fills it and ships it to your door.
- Who's eligible: typically adults with a BMI of 27 or higher, or a weight-related health condition, confirmed during intake.
- Who sets the dose: your provider selects your starting dose and adjusts it over time — you don't choose your own.
- What titration costs: nothing extra at PlexusDx — one rate at every dose level. MEDVi likewise states "Same Price. All Dosage Levels."
- Questions: at PlexusDx you can bring any to your free check-in with Dr. Jayden Lee, PharmD.
Compounded medications are not FDA-approved and are not reviewed by the FDA for safety, quality, or effectiveness. They are a legal, provider-prescribed option prepared by a licensed pharmacy — not a generic or a substitute the FDA has evaluated.
Does either program look at your biology or include pharmacist support?
Neither program includes a DNA-based test as part of its GLP-1 program. PlexusDx offers one as an optional add-on — $298, or $99 for program members.
The optional Precision Peptide Genetic Test gives you and your licensed provider added clarity on how your body is wired. The idea is simple: know your biology, don't guess at it.
- What it reads: how your genes influence weight-management-related pathways — the biology behind appetite, metabolism, and how your body handles fats and carbohydrates.
- Price: $298, or $99 for program members.
- What it isn't: it does not select or predict a medication; your provider decides — and it won't predict how you'll respond. It's context, not a prescription.
Every PlexusDx prescription includes a free 15-minute check-in with our Medical Director and Doctor of Pharmacy — by video or phone — to talk through medication questions, side effects, and how your protocol is going. It's education and support; your licensed provider still makes every prescribing decision.
How did we verify these prices?
We completed MEDVi's full signup to two checkout order summaries on July 20, 2026 — the semaglutide 3-month bundle at $475 and the tirzepatide 12-month bundle at $2,859. Every MEDVi figure comes from that capture.
Method. We went through MEDVi's intake from the first health question to two rendered checkout order summaries on July 20, 2026 — 19 dated captures covering the twelve-screen questionnaire, both plan-selection screens (semaglutide and tirzepatide), and the two checkouts. Those captures are the source for every MEDVi figure on this page; we did not take any MEDVi price from a third-party review site or aggregator.
What we could not verify at checkout. Two things. MEDVi's ongoing Monthly-plan rate — $299 semaglutide, $399 tirzepatide — was read from its plan-selection cards, not from a rendered order summary; the two totals we did render at checkout were the 3-month and 12-month bundles. And MEDVi's oral tablet — a flat +$70 over its injection for both compounds, confirmed on a later plan-selection screen — was read there rather than at a rendered checkout, so we cite the +$70 upcharge but publish no specific MEDVi tablet monthly total.
A note on who wrote this. PlexusDx publishes this page and is one of the two programs compared, so we are not a neutral party. That's why we used MEDVi's own plan-selection and checkout screens as the only source for its figures, and why we state plainly where MEDVi beats us. Category pricing changes often; check both sites before you decide.
- MEDVi's first month is cheaper. Its $159/$259 promotional first month runs about $30 below our $189/$289 on both compounds, then reverts to $299/$399.
- MEDVi's deepest prepaid tirzepatide is cheaper than any PlexusDx tier. Its 12-month bundle — $2,859 at checkout, about $238/month — runs about $11/month under our 6-month tirzepatide rate of $249, on a 48-week prepaid commitment (or Klarna financing).
- Its 12-month semaglutide ties our 6-month rate. Both work out to about $149/month — MEDVi requires the longer 48-week commitment to get there.
- MEDVi's inclusions are generous. Free care coaching, a free dietitian visit, board-certified physician review, unlimited doctor calls seven days a week, and Klarna 0% financing on multi-month plans.

Start your intakeFrequently Asked Questions
What is compounded GLP-1?
Compounded GLP-1 medications are semaglutide or tirzepatide prepared for an individual patient by a state-licensed 503A compounding pharmacy on a valid prescription. They are not FDA-approved. Both MEDVi and PlexusDx operate in this category.
- Not FDA-reviewed. Compounded medications are not reviewed by the FDA for safety, quality, or effectiveness.
- The approved versions. Only Novo Nordisk (semaglutide) and Lilly (tirzepatide) make FDA-approved branded products.
Is the compounded medication FDA-approved?
No — compounded medications are not FDA-approved and are not reviewed by the FDA for safety, quality, or effectiveness. They are prepared by a state-licensed 503A pharmacy for an individual patient on a valid prescription.
- Semaglutide. Novo Nordisk is the only U.S. company with FDA-approved semaglutide (Wegovy®, Ozempic®, Rybelsus®).
- Tirzepatide. Lilly is the only U.S. company with FDA-approved tirzepatide (Zepbound®, Mounjaro®).
Is PlexusDx cheaper than MEDVi?
On the ongoing month-to-month rate, yes — $189 versus $299 for semaglutide and $289 versus $399 for tirzepatide, a $110/month difference after MEDVi's first month. MEDVi's $159/$259 promotional first month is lower than ours, and its 12-month prepaid bundles are at or below our 6-month rates.
- On the Monthly plan over a year, PlexusDx runs about $1,180 cheaper on both compounds — $2,268 versus ≈$3,448 for semaglutide, $3,468 versus ≈$4,648 for tirzepatide.
- At the deepest prepaid tier, MEDVi's 12-month tirzepatide bundle ($2,859 at checkout, about $238/month) is below our 6-month rate of $249/month, and its 12-month semaglutide (≈$149/month) ties ours — both on a 48-week commitment.
How much does MEDVi cost per month?
When we completed MEDVi's signup on July 20, 2026, its Monthly plan was a $159 promotional first month for semaglutide and $259 for tirzepatide, then $299 and $399 ongoing. Its deepest 12-month prepaid bundles work out to about $149 and $238 per month.
- In between, the 3-month plans ran $158/$256 per month and the 6-month plans $153/$253, all prepaid bundles.
- Two totals were checkout-verified: the semaglutide 3-month bundle at $475 and the tirzepatide 12-month bundle at $2,859, both with free shipping.
How much does MEDVi cost per year?
On MEDVi's Monthly plan, about $3,448 for semaglutide and $4,648 for tirzepatide in year one — the promotional first month plus eleven months at the ongoing rate. Its 12-month prepaid bundles are about $1,788 for semaglutide and $2,859 for tirzepatide.
- The tirzepatide figure is checkout-verified: the 12-month bundle order summary read $2,859 — about $238/month across a 48-week supply.
- PlexusDx comparison: month-to-month works out to $2,268 and $3,468 a year; on the 6-month rate, $1,788 and $2,988.
Does MEDVi charge a membership fee?
No — MEDVi states that all its plans include everything with no membership fee, and PlexusDx charges no membership either. Neither program adds a recurring fee on top of the medication price.
- MEDVi's inclusions: board-certified physician review, free care coaching, a free dietitian visit, and unlimited doctor calls seven days a week.
- PlexusDx's price covers the provider consult, prescription, medication, and shipping in one flat charge.
Does the price change as my dose increases?
No — PlexusDx charges the same price at every dose level, and MEDVi states the same policy: "Same Price. All Dosage Levels." Flat pricing at every dose is table stakes in this category — both programs offer it.
- Why it matters: GLP-1 doses typically titrate upward over the first months; neither program raises its price as your dose increases.
Can I cancel anytime, or am I locked into a contract?
Both programs sell a monthly plan you can cancel: MEDVi's Monthly plan is an auto-renewing subscription you can cancel per its terms, and PlexusDx's month-to-month plan has no contract. Multi-month plans at both are prepaid commitments.
- MEDVi's terms state that cancellation stops future charges and that multi-month packages "will not be refunded for unused medication or remaining months."
- PlexusDx's 3- and 6-month rates involve a longer commitment for a lower price; its longest plan is 6 months. MEDVi's bundles run up to 12 months (48 weeks), with Klarna 0% financing available.
Which states is PlexusDx available in?
PlexusDx is available in most U.S. states where telehealth prescribing of these medications is permitted. You'll confirm whether your state is covered during intake. MEDVi operates on a similar state-by-state basis.
Is shipping included, and how does it work?
Yes — PlexusDx includes direct-to-door shipping in its monthly price, with no separate shipping fee. Your medication ships from a state-licensed 503A pharmacy in discreet packaging after your provider approves it. MEDVi's shipping is also free.
- MEDVi's checkout showed shipping as free on both order summaries, alongside a "Prescribed & shipped within 48 hours" badge.
What are the common side effects, and what support is there?
The most common GLP-1 side effects are gastrointestinal — nausea and digestive changes — usually most noticeable when starting or increasing a dose. Your provider titrates your dose to manage tolerability. This page is not medical advice.
- Every PlexusDx prescription includes a free 15-minute check-in with Dr. Jayden Lee, PharmD, for side-effect and medication questions.
- MEDVi includes free care coaching, a free dietitian visit, and unlimited doctor calls seven days a week.
- Discuss any symptoms with your provider.
Does PlexusDx offer anything MEDVi doesn't?
Four things stood out in our comparison: pricing published before intake, more formats — the GLP-Squared combination and a $129/month microdose, plus an oral option that costs less than MEDVi's oral tablet — an optional genetics test, and a named PharmD check-in. MEDVi offers both injections and an oral tablet, with its pricing shown after its health questionnaire.
- Every PlexusDx tier is published on its product pages before you start intake — $189/$289 month-to-month, down to $149/$249 on 6-month rates.
- MEDVi counters with generous inclusions — a free dietitian visit, care coaching, unlimited doctor calls — and Klarna 0% financing.
What does the PlexusDx genetics test do?
It analyzes how your genes influence weight-management-related biological pathways, to inform your conversation with your provider. It does not select or predict a medication; your provider decides.
- An optional add-on — $298, or $99 for program members. Neither program includes a DNA-based test as part of its GLP-1 program.
- It does not recommend, prescribe, or determine which medication you should use, and it does not predict your response to any specific drug.
PlexusDx tells you about your biology. It does not tell you what to put in your body.
