The short answer

Both MEDVi and PlexusDx offer cancel-anytime monthly billing, so you can time your switch without penalty. Start the PlexusDx intake 7–10 days before your next MEDVi shipment is due, complete the provider visit and prescription approval, then cancel MEDVi once your PlexusDx order ships. This overlap window keeps you on the same dose and compound without a gap. MEDVi charges $299/month for ongoing semaglutide refills and $399/month for tirzepatide (after a lower first-month rate); PlexusDx offers semaglutide injection at $189/month and tirzepatide injection at $289/month on a month-to-month basis, with commitment tiers at $169/$269 (3-month) and $149/$249 (6-month). Over 12 months the difference is $1,320 on either compound when comparing month-to-month rates.

At-a-glance: MEDVi vs PlexusDx

All pricing captured September 2026. MEDVi first-month introductory rates ($179 semaglutide, $279 tirzepatide) and refill rates ($299/$399) verified via checkout flow September 4, 2026. PlexusDx pricing verified July 20, 2026.

Step-by-step switching process

1. Note your current MEDVi dose and shipment schedule

Check your MEDVi account or most recent shipment label for your current compound (semaglutide or tirzepatide), route (injection or oral), and dose in milligrams. Write down the date your next refill is scheduled to ship. You will share this dose history during the PlexusDx intake so the new provider can assess continuity and whether the same dose remains appropriate.

2. Start the PlexusDx intake 7–10 days before your next MEDVi shipment

Complete the PlexusDx online intake 7–10 days before your next MEDVi order is due. The intake collects your medical history, current medications, treatment goals, and dose history. A licensed clinician reviews your submission, conducts a telehealth visit if required by your state, and decides whether to issue a prescription. Approval typically occurs within 1–2 business days, and the pharmacy ships within 1–3 business days after prescription receipt. This 7–10 day buffer gives you time to receive tracking and confirm shipment before canceling MEDVi.

3. Wait for PlexusDx prescription approval and shipment confirmation

Once the PlexusDx provider approves your prescription and the pharmacy generates a tracking number, you have concrete evidence that your new supply is en route. Do not cancel MEDVi until you see this tracking confirmation. If the provider requests additional information or declines to prescribe, you remain on MEDVi without interruption.

4. Cancel your MEDVi subscription

MEDVi operates on monthly billing with no contract; you may cancel anytime (verified September 4, 2026). Log into your MEDVi account, navigate to subscription settings, and cancel. If you purchased a multi-month bundle, note that MEDVi bundles are non-refundable for unused months (verified July 20, 2026), so it may make sense to switch at the end of a bundle term. Contact MEDVi support if you need clarification on your billing cycle or bundle status.

5. Coordinate overlapping supply or back-to-back delivery

If your PlexusDx shipment arrives before your MEDVi supply runs out, you will have a small overlap. Store the extra vials or tablets according to package instructions (refrigerate injection vials, store oral tablets at room temperature) and use your MEDVi supply first if the dates are similar, or follow your new provider's instruction. If your PlexusDx order is delayed, you can request an expedited refill from MEDVi or ask the PlexusDx pharmacy for rush processing; communication with both support teams is key during the handoff window.

6. Confirm dose continuity with your new PlexusDx provider

The PlexusDx clinician may continue your current dose or adjust based on your response, side effects, and clinical guidelines. If the provider recommends a dose change, ask for the rationale and timeline. Dose adjustments are a normal part of GLP-1 therapy, but abrupt changes without clinical justification warrant clarification. Your MEDVi dose history provides the baseline; the new provider decides next steps.

Price comparison: ongoing monthly rates

MEDVi advertises a first-month introductory rate—$179 for semaglutide injection and $279 for tirzepatide—but refills jump to $299 and $399 per month, respectively (verified September 4, 2026). PlexusDx pricing is flat at every dose, with no introductory discount and no surprise increase at refill.

Semaglutide injection

• MEDVi refill rate: $299/month
• PlexusDx month-to-month: $189/month
• PlexusDx 3-month commitment: $169/month (billed as $507 every three months)
• PlexusDx 6-month commitment: $149/month (billed as $894 every six months)

12-month cost (our calculation): MEDVi $3,588 (12 × $299) vs PlexusDx $2,268 (month-to-month), $2,028 (3-month), or $1,788 (6-month). Switching to PlexusDx month-to-month saves $1,320 over one year on semaglutide.

Tirzepatide injection

• MEDVi refill rate: $399/month
• PlexusDx month-to-month: $289/month
• PlexusDx 3-month commitment: $269/month (billed as $807 every three months)
• PlexusDx 6-month commitment: $249/month (billed as $1,494 every six months)

12-month cost (our calculation): MEDVi $4,788 (12 × $399) vs PlexusDx $3,468 (month-to-month), $3,228 (3-month), or $2,988 (6-month). Switching to PlexusDx month-to-month saves $1,320 over one year on tirzepatide.

Oral formulations

MEDVi charges a $70 surcharge for semaglutide oral tablets ($249 first month, $369 refill) and lists tirzepatide oral at the same first-month and refill rates as tirzepatide injection ($279/$399), with no separate oral surcharge displayed (verified September 4, 2026). PlexusDx offers semaglutide oral capsules at $289 month-to-month ($269 3-month, $249 6-month) and tirzepatide oral capsules at $349 month-to-month ($299 3-month, $279 6-month). Confirm current oral pricing at checkout, as oral-formulation rates and availability can shift.

What stays the same, what changes

Continuity factors

• Compound and dose: Both platforms dispense compounded semaglutide and tirzepatide in injection and oral forms. The PlexusDx provider can continue your current dose if clinically appropriate, or recommend an adjustment based on your response and tolerance.
• Compounding pharmacy network: Both MEDVi and PlexusDx work with licensed 503A compounding pharmacies. The specific pharmacy partner may differ, so vial appearance, packaging, and ancillary supplies (needles, syringes, alcohol wipes) may vary slightly.
• Telehealth model: Both offer online intake, asynchronous or synchronous provider visits (depending on state requirements), and digital prescription transmission to the pharmacy.
• Monthly shipment cadence: Both ship on a monthly cycle. You can adjust shipment dates within each provider's account portal to align with your schedule.

Key differences

• Pricing structure: MEDVi uses a discounted first-month rate followed by a higher refill rate ($299 semaglutide, $399 tirzepatide). PlexusDx charges the same rate every month, with optional commitment discounts.
• Support model: MEDVi includes unlimited doctor calls, care coaching, and a free dietitian visit (verified July 20, 2026). PlexusDx includes medication, consult, prescription, and shipping in the base price, plus a free check-in with a Doctor of Pharmacy; additional dietitian or coaching services are not included.
• Commitment options: MEDVi offers 3-, 6-, and 12-month bundles with 0% financing and a 48-week maximum term, but bundles are non-refundable for unused months (verified July 20, 2026). PlexusDx offers 3-month and 6-month commitment plans with lower per-month rates; early cancellation terms vary by plan and should be confirmed during intake.
• Pricing transparency: MEDVi shows pricing after you complete the health questionnaire (verified July 20, 2026). PlexusDx publishes every tier on the product page before intake (verified July 20, 2026).

Common switching scenarios and timing guidance

Scenario A: You are on MEDVi month-to-month and want to switch immediately

Start the PlexusDx intake 7–10 days before your next MEDVi auto-refill date. Once you receive PlexusDx tracking confirmation, cancel MEDVi. Your final MEDVi charge will process for the current billing cycle; you will not receive a pro-rated refund for unused days within that month.

Scenario B: You prepaid a MEDVi 3-, 6-, or 12-month bundle

Because MEDVi bundles are non-refundable for unused months, the lowest-cost approach is to switch at the end of your bundle term. If the price difference justifies absorbing the sunk cost, you can switch mid-bundle, but you will forfeit the prepaid months. Calculate the breakeven: if you have four months remaining on a bundle and the monthly savings with PlexusDx is $110 (semaglutide refill $299 vs PlexusDx $189), you save $440 over those four months—less than the ~$1,196 you prepaid (4 × $299). In that scenario, finishing the MEDVi bundle and then switching is more economical. If you have only one or two months left, the decision is closer; run the numbers with your specific bundle terms.

Scenario C: You want to try a different dose or formulation

Switching providers is an opportunity to discuss dose adjustments or route changes (injection to oral, or vice versa) with a new clinician. Mention your goal during the PlexusDx intake. The provider will assess your history, current response, side effects, and preferences, then decide whether a change is medically appropriate. Do not adjust your dose on your own during the transition; follow the provider's titration schedule.

Scenario D: Supply chain delay or approval delay

If the PlexusDx provider requests additional records or if the pharmacy experiences a shipping delay, you may approach your next MEDVi refill date without PlexusDx tracking. In this case, let the MEDVi refill process, continue treatment without interruption, and cancel MEDVi once your PlexusDx order ships. You will pay for one overlapping month, but you avoid a treatment gap and the potential return of appetite or weight rebound that can occur even after a few missed doses.

What to expect from the PlexusDx intake and onboarding

1. Online intake form: Medical history, current medications, weight and metabolic health history, prior GLP-1 use (including your MEDVi dose and duration), and treatment goals. The form takes about 60 seconds to complete.
2. Provider review: A licensed clinician reviews your submission. Some states require a live video visit; others permit asynchronous review. The provider decides whether to issue a prescription, continue your current dose, or recommend an adjustment.
3. Prescription transmission: Once approved, the prescription goes to a licensed 503A compounding pharmacy in the PlexusDx network.
4. Pharmacy fulfillment: The pharmacy compounds your medication, packages it with supplies (syringes, needles, alcohol wipes for injection; dosing instructions for oral), and ships via temperature-controlled courier. You receive tracking within 1–3 business days of prescription receipt.
5. Ongoing refills: PlexusDx auto-refills on your selected cycle (monthly for month-to-month, or at the interval of your commitment plan). You can pause, skip, or cancel through your account portal.
6. PharmD check-in: A Doctor of Pharmacy is available for a free check-in to answer questions about administration, storage, side effects, and drug interactions.

No charge is processed until the provider approves your prescription. If the provider declines to prescribe, you are not billed.

Provider support and clinical oversight during the switch

MEDVi includes unlimited doctor calls, care coaching, and a dietitian visit in the monthly price (verified July 20, 2026). If you rely heavily on frequent clinician contact or structured coaching, confirm that PlexusDx's support model—medication, consult, prescription, shipping, and a free PharmD check-in—meets your needs. PlexusDx does not include unlimited coaching or dietitian visits in the base price. If those services are important to you, budget for separate coaching or verify whether your health insurance covers dietitian visits outside the telehealth platform.

Both platforms assign a licensed provider who oversees your prescription. You can message your provider through the patient portal with questions about side effects, dose adjustments, or contraindications. Response times vary; MEDVi advertises "unlimited doctor calls," while PlexusDx offers asynchronous messaging and PharmD support. If you prefer synchronous phone or video access to a physician, clarify availability during your intake.

Regulatory and safety considerations

Compounded medications are not FDA-approved. The FDA does not review compounded drugs before marketing for safety, effectiveness, or quality. A licensed clinician determines whether a prescription is appropriate for an individual patient. PlexusDx works with licensed 503A compounding pharmacies.

Both MEDVi and PlexusDx dispense compounded semaglutide and tirzepatide, not branded Wegovy, Ozempic, Zepbound, or Mounjaro. Compounded formulations may differ in inactive ingredients, concentration, and packaging from branded products. Your provider decides which formulation and dose are appropriate based on your clinical profile.

If you experience severe side effects—persistent vomiting, severe abdominal pain, vision changes, signs of pancreatitis, or allergic reaction—contact your provider immediately and seek emergency care if warranted. Do not switch providers or adjust doses without clinical guidance if you are experiencing acute side effects.

Review and reliability snapshot

MEDVi holds a 4.3-star rating on Trustpilot with approximately 15,000 reviews (captured September 4, 2026). No specific negative themes were coded from recent Trustpilot or Reddit review passes, suggesting general satisfaction and reliable fulfillment at the aggregate level. Individual experiences vary, and prospective patients should read recent reviews to understand current service quality.

PlexusDx holds a 4.3-star rating on Trustpilot, with 79% of reviews at five stars and 83% at four stars or higher (captured September 9, 2026). Both platforms demonstrate a track record of patient satisfaction and operational reliability in the compounded GLP-1 telehealth space.

Choose MEDVi if…

• You value unlimited synchronous doctor calls, included care coaching, and a free dietitian visit, and those services justify the higher monthly refill cost.
• You are still in your first month and benefiting from the $179 semaglutide or $279 tirzepatide introductory rate; the price advantage flips at refill.
• You are locked into a prepaid multi-month bundle with significant time remaining, and the sunk cost of switching mid-term outweighs the monthly savings with PlexusDx.
• You prefer the MEDVi user interface, support responsiveness, or pharmacy network based on your direct experience, and the price difference is not a deciding factor for your budget.

Choose PlexusDx if…

• You want a lower ongoing monthly rate with no first-month-vs-refill price jump: $189/month for semaglutide injection or $289/month for tirzepatide injection on a cancel-anytime month-to-month plan.
• You are willing to commit to a 3-month or 6-month term in exchange for deeper per-month discounts ($169/$149 semaglutide, $269/$249 tirzepatide).
• You prefer transparent pricing published on the product page before intake, with no questionnaire gate.
• You are comfortable with asynchronous provider messaging and PharmD support rather than unlimited live doctor calls, and you do not require included coaching or dietitian visits.
• You are approaching the end of a MEDVi bundle or are currently on MEDVi month-to-month, so switching incurs no sunk cost.

Practical checklist for a smooth handoff

1. Write down your current compound, route, dose, and next MEDVi shipment date.
2. Complete the PlexusDx intake 7–10 days before that shipment date.
3. Wait for provider approval and pharmacy tracking confirmation.
4. Cancel MEDVi through your account portal once you have PlexusDx tracking.
5. Monitor both shipments; contact support if either is delayed.
6. Store any overlapping supply according to package instructions.
7. Follow your new provider's dosing instructions and report any side effects promptly.
8. Confirm your first PlexusDx auto-refill date and update your payment method if needed.

Methodology and freshness

All MEDVi pricing (first-month and refill rates for semaglutide and tirzepatide, injection and oral) was verified via checkout flow on September 4, 2026. MEDVi cancellation policy, support inclusions, and bundle terms were verified July 20, 2026 and September 4, 2026. PlexusDx pricing for semaglutide injection, tirzepatide injection, semaglutide oral, tirzepatide oral, and microdose GLP-1 was verified July 20, 2026; month-to-month and commitment tiers are current as of that date. Review ratings (Trustpilot) for both platforms were captured September 4, 2026. Twelve-month cost comparisons are our calculation, derived by multiplying verified monthly rates by twelve or by the appropriate number of commitment cycles. No figures were derived by applying promotional discounts or coupons; all prices reflect observed checkout or published rates at the time of capture. Readers should confirm pricing, commitment terms, and product availability at intake, as telehealth platforms adjust rates and medication rosters in response to ingredient cost, regulatory changes, and competitive dynamics.

Frequently Asked Questions

Can I switch from MEDVi to PlexusDx mid-month without losing my current dose?

Yes. Start the PlexusDx intake 7–10 days before your next MEDVi refill is due, wait for provider approval and tracking confirmation, then cancel MEDVi. This timeline ensures your new supply ships before your current supply runs out, so you stay on the same compound and dose without interruption.

Will I pay a cancellation fee if I leave MEDVi?

No. MEDVi operates on monthly billing with no contract, and you may cancel anytime (verified September 4, 2026). If you purchased a multi-month bundle, note that MEDVi bundles are non-refundable for unused months, so switching mid-bundle means you forfeit the prepaid portion. Month-to-month subscribers face no penalty.

Does PlexusDx include unlimited doctor calls and coaching like MEDVi?

No. MEDVi includes unlimited doctor calls, care coaching, and a free dietitian visit in the monthly price. PlexusDx includes medication, consult, prescription, shipping, and a free check-in with a Doctor of Pharmacy. If you want ongoing coaching or dietitian support with PlexusDx, you will need to arrange and pay for those services separately or through your health insurance.

How long does PlexusDx provider approval take?

Most PlexusDx provider reviews are completed within 1–2 business days of intake submission. If the provider requests additional medical records or clarification, approval may take longer. Once approved, the pharmacy typically ships within 1–3 business days. Starting your intake 7–10 days before your MEDVi refill date builds in buffer time for these steps.

Can I use insurance or an HSA/FSA to pay for PlexusDx?

PlexusDx pricing is out-of-pocket; the platform does not bill insurance directly. Some patients use a Health Savings Account (HSA) or Flexible Spending Account (FSA) debit card at checkout, but you should confirm with your HSA/FSA administrator whether compounded GLP-1 medications qualify under your plan. You may also submit a superbill to your insurance for potential reimbursement, though coverage for compounded weight-loss medications is uncommon.
