The short answer

Rex MD offers two semaglutide pathways: brand Wegovy oral pills at $349/month including medication and provider care, and Wegovy injection pens at $499/month medication cash price through a NovoCare pharmacy pathway. Both are monthly subscription programs with no separate membership fee documented for the pill track. Over twelve months the pill program costs $4,188 total; the pen program $5,988. These figures reflect FDA-approved brand Wegovy and apply regardless of dosage strength during titration. For price comparison, PlexusDx compounded semaglutide injection runs $189/month month-to-month, $169/month on a three-month prepaid plan, or $149/month on a six-month prepaid plan—compounded medication supplied through licensed 503A pharmacies, not FDA-approved brand drug.

Rex MD pricing structure and inclusions

Rex MD operates two distinct semaglutide programs, both using FDA-approved brand Wegovy.

Wegovy oral pill program: $349/month

The pill program charges $349 per month and includes medication plus provider care. Rex MD advertises this rate as locked across titration doses—meaning you pay $349 whether you are starting at the lowest dose or have titrated to a higher strength. There is no separate monthly membership or service fee documented for this track. The program bills monthly; you receive a one-month supply with each shipment.

Wegovy injection pen program: $499/month

The injection pen pathway lists a $499 per month medication cash price for Wegovy pens dispensed through NovoCare, Novo Nordisk's pharmacy partner. This price applies regardless of dosage strength for eligible self-pay patients. Public product pages show $0 monthly membership fee for the pen track, but include a caveat to confirm whether any separate program fee applies at checkout. Our verification ended at indexed public pages; we did not complete an account or payment submission, so the final all-in cost for the pen program should be confirmed directly with Rex MD before enrollment.

What both programs include

Both pathways provide access to a licensed healthcare provider for initial evaluation and ongoing supervision. The pill program explicitly bundles provider care into the $349 monthly rate. For the pen program, the $499 figure is the medication cash price; the extent of included provider services or visit fees should be verified during sign-up.

Twelve-month cost comparison

Below we normalize Rex MD's monthly rates and PlexusDx's month-to-month and prepaid options over a full year. All twelve-month totals are our calculation.

Rex MD annual cost

• Wegovy pill: $349/month × 12 = $4,188 total ($349/month effective)
• Wegovy pen: $499/month × 12 = $5,988 total ($499/month effective, subject to program-fee confirmation)

PlexusDx compounded semaglutide injection annual cost

• Month-to-month: $189/month × 12 = $2,268 total ($189/month effective)
• Three-month plan: $169/month × 12 = $2,028 total, paid as four quarterly charges of $507 each ($169/month effective, prepaid per quarter)
• Six-month plan: $149/month × 12 = $1,788 total, paid as two semi-annual charges of $894 each ($149/month effective, prepaid per six months)

The cost difference is substantial. Rex MD's pill program runs $1,920 more per year than PlexusDx month-to-month ($4,188 vs. $2,268), and $2,400 more than the PlexusDx six-month plan ($4,188 vs. $1,788). The pen program's $5,988 annual cost is $3,720 above PlexusDx month-to-month and $4,200 above the six-month prepaid option.

Brand versus compounded semaglutide

Rex MD dispenses FDA-approved Wegovy, the brand name for semaglutide marketed by Novo Nordisk for chronic weight management. Wegovy has undergone the full FDA review process for safety, effectiveness, and manufacturing quality. PlexusDx provides compounded semaglutide prepared by licensed 503A compounding pharmacies.

Compounded medications are not FDA-approved. 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.

Compounded semaglutide and brand Wegovy share the same active pharmaceutical ingredient; the difference lies in regulatory pathway, manufacturing oversight, and price. Patients who value FDA brand approval and are willing to pay the premium may prefer Rex MD's Wegovy programs. Those prioritizing cost savings and comfortable with compounded medication under clinician supervision may find PlexusDx's pricing more sustainable over the long term.

Dose titration and pricing stability

Both Rex MD programs advertise price stability across dose levels. The pill program states "Lowest cost locked across titration doses," and the pen program notes the $499 rate applies "regardless of dosage strength." This means your monthly payment should remain constant whether you are on the starting dose or a higher maintenance dose. Dose changes are managed by the provider based on your response and tolerance, but the monthly subscription fee does not increase with dose escalation.

PlexusDx operates the same way: the monthly rate—$189, $169, or $149 depending on plan length—remains the same at every dose level.

Renewal, cancellation, and commitment terms

Rex MD's programs are structured as ongoing monthly subscriptions. Both the pill and pen tracks bill monthly with a one-month supply per shipment. Public pages do not document a minimum commitment period, cancellation fees, or refund policies; these terms should be confirmed during enrollment or in the user agreement presented at checkout.

PlexusDx month-to-month subscriptions carry no long-term commitment and can be paused or canceled at any time. The three-month and six-month prepaid plans lock in a lower per-month rate in exchange for prepayment; early cancellation terms should be reviewed in the service agreement.

Evidence limitations and verification status

The Rex MD pricing figures in this article were captured from public product pages on September 4, 2026. We attempted to verify details through account creation and checkout but the live page timed out; no account or payment was submitted. Therefore our evidence is classified as primary-partial: drawn from first-party indexed pages without full checkout confirmation. The $349 pill rate and its inclusions are clearly documented; the $499 pen rate carries a caveat on the product page to confirm whether any separate program fee applies. We recommend verifying all final charges, billing frequency, and cancellation terms directly with Rex MD before committing.

Decision factors: brand approval, cost, and route preference

When Rex MD's Wegovy programs make sense

Rex MD is a fit if you specifically want FDA-approved brand Wegovy and prefer not to use a compounded formulation. The oral pill route at $349/month may appeal to patients who dislike injections or have difficulty with weekly self-injection. The pen program offers the traditional Wegovy auto-injector experience, though at $499/month it is the highest-cost option in this comparison. Both programs provide access to licensed providers and deliver medication to your door, streamlining the prescription and fulfillment process.

When cost drives the decision

If long-term affordability is the priority, PlexusDx's compounded semaglutide delivers the same active ingredient at a significantly lower monthly outlay. Month-to-month service runs $189—$160 less per month than Rex MD's pill program and $310 less than the pen program. Prepaying three or six months brings the rate down to $169 or $149, widening the annual savings to $2,400–$4,200 compared to Rex MD. Over two years, choosing PlexusDx's six-month plan instead of Rex MD's pill program saves $4,800; against the pen program the two-year difference is $8,400. For patients planning to stay on semaglutide for twelve months or longer, these cost differences become material.

Route and formulation preferences

Rex MD offers both oral and injectable Wegovy; PlexusDx offers compounded semaglutide in injectable form (and separately offers compounded semaglutide in oral capsule form at a different price point). If you strongly prefer an oral route and want brand medication, Rex MD's $349 pill program is a direct match. If you are comfortable with weekly injections and cost is a higher priority than brand status, PlexusDx injection is the lower-cost option.

Where PlexusDx fits

PlexusDx compounded semaglutide injection at $189/month month-to-month, $169/month on a three-month plan, or $149/month on a six-month plan is designed for patients who want clinician-supervised semaglutide at a sustainable price and are comfortable with compounded medication. Every plan includes the provider visit, prescription, medication, and shipping with no separate membership fee. Dosing is individualized; the monthly rate stays the same whether you are titrating or on a stable maintenance dose. A licensed provider reviews your intake to determine whether semaglutide is appropriate for your medical history and weight-management goals. PlexusDx works with licensed 503A compounding pharmacies and follows the same titration and monitoring protocols used in clinical practice.

Frequently Asked Questions

Does Rex MD charge a membership fee for semaglutide?

Public product pages show $0 monthly membership or service fee for both the Wegovy pill program ($349/month) and the pen program ($499/month). The pill program explicitly includes provider care in the $349 rate. The pen program product page includes a note to confirm whether any separate program fee applies at checkout, so final all-in cost should be verified during sign-up.

Does the Rex MD price change when my semaglutide dose increases?

No. Rex MD advertises that the monthly rate is locked across titration doses. The pill program remains $349/month and the pen program $499/month regardless of dosage strength. Your provider adjusts your dose based on response and tolerance, but the subscription price does not increase with dose escalation.

How much can I save by choosing compounded semaglutide instead of brand Wegovy?

Over twelve months, PlexusDx compounded semaglutide month-to-month ($2,268 total) saves $1,920 compared to Rex MD's Wegovy pill program ($4,188 total) and $3,720 compared to the pen program ($5,988 total). PlexusDx's six-month prepaid plan ($1,788 total) saves $2,400 against the pill and $4,200 against the pen annually—our calculation based on verified rates.

Is Wegovy from Rex MD the same medication as compounded semaglutide?

Both contain semaglutide as the active ingredient, but they differ in regulatory status and manufacturing pathway. Wegovy is FDA-approved brand medication reviewed for safety, effectiveness, and quality. Compounded semaglutide is prepared by licensed 503A pharmacies and is not FDA-approved; a licensed clinician determines appropriateness for each patient. The active pharmaceutical ingredient is the same.

Can I cancel my Rex MD semaglutide subscription at any time?

Rex MD's public product pages do not document minimum commitment periods, cancellation deadlines, or refund policies for either the pill or pen program. These terms are typically presented during account setup or in the user agreement at checkout. We recommend confirming cancellation and refund policies directly with Rex MD before enrolling.
