PlexusDx publishes this comparison and is one of the providers discussed. We use the same evidence rules for our own program and competing programs.

The short answer

MEDVi advertises a first-month introductory rate of $179 for compounded semaglutide injection, then refills at $299/month ongoing (verified via checkout 2026-09-04). PlexusDx charges $189/month from day one (no introductory discount, no refill increase). Over 12 months at the month-to-month rate, PlexusDx totals $2,268; MEDVi totals $3,468 ($179 first month plus 11 refills at $299). The same pattern holds for tirzepatide: MEDVi's first-month rate is $279, refills are $399; PlexusDx is $289 every month. If you commit to three or six months with PlexusDx, the per-month rate drops further ($149–$169 for semaglutide, $249–$269 for tirzepatide). Both programs include the provider visit, prescription, medication, and shipping in the published price; neither charges a membership fee for compounded medications. MEDVi also offers multi-month bundles with 0% financing through Klarna, but the bundle rates are not public and unused months are non-refundable. If you prefer predictable pricing and a lower total cost at the ongoing rate, PlexusDx wins on both counts. If an introductory discount matters more than the refill rate and you plan to stay only one or two months, MEDVi's first-month offer may appeal—but most people continue longer than that, and the refill rate drives total cost.

At a glance: MEDVi vs PlexusDx

The intro-rate vs refill-rate math: 12 months side by side

MEDVi's advertised first-month rate for compounded semaglutide injection is $179 (verified via checkout 2026-09-04). Refills are $299/month. Over 12 months on the month-to-month plan, you pay $179 once, then $299 eleven times: $179 + ($299 × 11) = $3,468 (our calculation). PlexusDx charges $189 every month, no introductory discount: 12 × $189 = $2,268 (our calculation). The effective ongoing rate at MEDVi—the price you see in months 2 through 12—is $110 higher per month than PlexusDx's constant rate, and the $120 you save in month one does not offset the cumulative difference. Over a year, PlexusDx costs $1,200 less at the month-to-month rate.

For tirzepatide injection, MEDVi's first-month rate is $279, refills are $399 (verified 2026-09-04). Over 12 months: $279 + ($399 × 11) = $4,668 (our calculation). PlexusDx charges $289 every month: 12 × $289 = $3,468 (our calculation). The year-one difference is again $1,200 in PlexusDx's favor.

If you commit to three or six months with PlexusDx, the per-month rate drops further. Semaglutide injection costs $169/month on a three-month commitment ($2,028/year, our calculation) or $149/month on a six-month commitment ($1,788/year, our calculation). Tirzepatide injection costs $269/month on a three-month commitment ($3,228/year, our calculation) or $249/month on a six-month commitment ($2,988/year, our calculation). Every commitment tier remains below MEDVi's refill rate and below MEDVi's total year-one cost.

MEDVi offers three-, six-, and 12-month bundles with 0% financing via Klarna over 12 months; the platform states it is "not a party" to that agreement (verified 2026-07-20). Bundle rates are not published, and bundles are non-refundable for unused months. Without published bundle pricing, this comparison uses the verified month-to-month rates for both programs.

What the published prices include

MEDVi's published price—$179 first month, $299 refills for semaglutide injection—includes the provider consultation, medication, unlimited doctor calls, and shipping (verified 2026-09-04). Free care coaching and a free dietitian visit are also included. Dose increases do not raise the monthly price. The compounded-medication track carries no membership fee; the $99/month membership applies only to MEDVi's branded Wegovy/Zepbound pathway, and the all-in cost for that pathway was not captured in this verification.

PlexusDx's published price—$189/month for semaglutide injection at the month-to-month rate—includes the provider visit, prescription, medication, and shipping (verified 2026-07-20). A free check-in with a Doctor of Pharmacy is included. Dose increases do not raise the monthly price. There is no membership fee. PlexusDx also offers an optional genetic test for medication response for $298 standalone or $99 for program members; the test does not select or predict medication—a licensed provider decides whether a prescription is appropriate.

Oral and tablet routes

MEDVi offers a compounded semaglutide tablet for an additional $70/month over the injection price (verified 2026-09-04). That means a first-month rate of $249 (our calculation: $179 + $70) and refills at $369/month (our calculation: $299 + $70). Compounded tirzepatide is available as an injection or oral formulation; no separate oral surcharge is displayed for tirzepatide.

PlexusDx offers compounded semaglutide oral capsules for $289/month month-to-month, $269/month on a three-month commitment, or $249/month on a six-month commitment (verified 2026-07-20). Compounded tirzepatide oral capsules are $349/month month-to-month, $299/month on a three-month commitment, or $279/month on a six-month commitment. PlexusDx's oral semaglutide costs less than MEDVi's tablet route at every commitment tier.

Multi-month commitments and bundles

PlexusDx publishes three commitment tiers: month-to-month (cancel anytime), three-month, and six-month (verified 2026-07-20). The three-month rate for semaglutide injection is $169/month; the six-month rate is $149/month. For tirzepatide injection, the three-month rate is $269/month and the six-month rate is $249/month. Every tier is a flat per-month charge; there is no upfront lump sum and no hidden dose-increase surcharge.

MEDVi offers three-, six-, and 12-month bundles with 0% financing via Klarna over 12 months (verified 2026-07-20). The platform states it is "not a party" to that financing agreement. Bundle rates are not published on the site. Bundles are non-refundable for unused months, and the longest prepaid term is 48 weeks (the 12-month bundle).

Support and coaching

MEDVi includes free care coaching, a free dietitian visit, and unlimited doctor calls (verified 2026-07-20 and 2026-09-04). PlexusDx includes a free check-in with a Doctor of Pharmacy; additional support is available but not characterized as unlimited in the verified evidence.

Pricing visibility and qualification

PlexusDx publishes all pricing tiers—month-to-month, three-month, and six-month—before you start the intake (verified 2026-07-20). MEDVi shows pricing after you complete the health questionnaire (verified 2026-07-20). Both programs require a provider to review your intake and determine whether a prescription is appropriate before any charge is made.

• You plan to use the medication for only one or two months and want the lowest possible first-month cost.
• You value unlimited doctor calls and dedicated care coaching as part of the published price.
• You prefer to see your final price after completing a health questionnaire rather than before.
• You are interested in a branded Wegovy or Zepbound pathway (PlexusDx offers compounded options only).

• You expect to continue for three months or longer and want the lowest total cost over that period.
• You prefer predictable pricing with no refill-rate increase.
• You want all pricing published before you begin the intake.
• You are interested in oral capsule formulations at a lower cost than competitor tablet routes.

Neither program guarantees eligibility, medication, dose, or results; a licensed clinician determines whether a prescription is appropriate for each individual.

Frequently Asked Questions

Does MEDVi's first-month discount offset the higher refill cost over a year?

No. MEDVi's $179 first-month rate for semaglutide saves you $120 compared to month two onward, but the refill rate of $299 is $110 higher per month than PlexusDx's $189 constant rate. Over 12 months, MEDVi totals $3,468 and PlexusDx totals $2,268—a $1,200 difference in PlexusDx's favor (our calculation, verified rates from 2026-09-04 and 2026-07-20).

What happens to MEDVi's price if my dose increases?

MEDVi states that dose increases do not raise the monthly price (verified 2026-09-04). You continue to pay $299/month for semaglutide injection or $399/month for tirzepatide injection after the first month, regardless of dose. PlexusDx follows the same policy: the published per-month rate holds at every dose (verified 2026-07-20).

Yes. PlexusDx publishes all commitment tiers—month-to-month, three-month, and six-month—on the product pages before you begin the intake (verified 2026-07-20).
