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

PlexusDx and Zappy Health both offer compounded semaglutide and tirzepatide with no separate membership fee, but their pricing structures diverge sharply in clarity and renewal terms. Zappy Health's official pages show conflicting prices: one landing page lists semaglutide at an advertised $159/month and tirzepatide at an advertised $279/month, while another official page states semaglutide costs "$199 first 3 months then $295" and tirzepatide "$299 first 3 months then $359" (all figures captured September 4, 2026, zappyhealth.com). It is unclear whether the $159 and $279 figures are introductory rates, standard monthly rates, or legacy pricing, and the renewal price you will pay requires checkout confirmation.

PlexusDx publishes one set of rates—$189/month semaglutide and $289/month tirzepatide on a month-to-month plan (captured September 12, 2026, plexusdx.com)—with no introductory period and no price increase at renewal. If Zappy Health's advertised $159 semaglutide rate holds month over month, it delivers a lower 12-month cost ($1,908 vs $2,268); if the "$199 then $295" structure applies, PlexusDx costs $984 less over the year. For tirzepatide, the same pattern holds: advertised $279/month at Zappy yields $3,348 over 12 months (vs $3,468 at PlexusDx), but the "$299 then $359" path climbs to $4,128—$660 more than PlexusDx. Without checkout clarity, readers planning budgets cannot know which scenario applies.

Pricing breakdown: advertised rates, documented conflicts, and 12-month costs

Zappy Health: conflicting official-page prices

Zappy Health's compounded-tirzepatide landing page (captured September 4, 2026) advertises semaglutide at $159/month and tirzepatide at $279/month, both billed monthly with no separate membership fee. Another official page on the same domain, captured the same day, states semaglutide costs "$199 first 3 months then $295" and tirzepatide "$299 first 3 months then $359" (zappyhealth.com, September 4, 2026). The evidence does not clarify whether the $159 and $279 figures are introductory rates that later increase, standard monthly rates that contradict the second page, or outdated pricing. Binding renewal terms require checkout confirmation.

Because the conflict is material, we calculate 12-month costs under both scenarios:

Scenario 1: Landing-page advertised rates hold monthly

• Semaglutide: advertised $159/month × 12 = $1,908 over 12 months (our calculation)
• Tirzepatide: advertised $279/month × 12 = $3,348 over 12 months (our calculation)

Scenario 2: Introductory rate then standard rate

• Semaglutide: ($199 × 3) + ($295 × 9) = $597 + $2,655 = $3,252 over 12 months (our calculation)
• Tirzepatide: ($299 × 3) + ($359 × 9) = $897 + $3,231 = $4,128 over 12 months (our calculation)

The difference between the two scenarios is $1,344 for semaglutide and $780 for tirzepatide. Readers should confirm which rate structure applies at checkout and verify renewal terms before the first charge.

PlexusDx: flat monthly rates, no introductory period

PlexusDx publishes one set of month-to-month rates with no promotional window and no price increase at renewal (plexusdx.com, captured September 12, 2026):

• Semaglutide injection: $189/month → $2,268 over 12 months (our calculation)
• Tirzepatide injection: $289/month → $3,468 over 12 months (our calculation)

PlexusDx also offers 3-month and 6-month commitment plans at lower per-month rates ($169 and $149 for semaglutide; $269 and $249 for tirzepatide), paid monthly over the commitment term. The same price applies at every dose, and the advertised rate is the renewal rate.

Head-to-head comparison: if Zappy's low rate holds, if the step-up applies

Semaglutide over 12 months

• If advertised $159/month at Zappy Health is the standard rate: Zappy delivers $1,908 total vs PlexusDx $2,268—a $360 advantage (our calculation).
• If the "$199 then $295" structure applies: Zappy totals $3,252 vs PlexusDx $2,268—PlexusDx costs $984 less (our calculation).

Tirzepatide over 12 months

• If advertised $279/month at Zappy Health is the standard rate: Zappy delivers $3,348 total vs PlexusDx $3,468—a $120 advantage (our calculation).
• If the "$299 then $359" structure applies: Zappy totals $4,128 vs PlexusDx $3,468—PlexusDx costs $660 less (our calculation).

The official-page conflict leaves the economic comparison unresolved until checkout. Readers planning multi-month budgets should verify renewal pricing in writing before committing.

Decision factors: transparency, commitment options, and regulatory status

Pricing clarity and renewal confidence

PlexusDx publishes one rate per medication and plan term, with no promotional period and no documented price increase at renewal. Zappy Health's conflicting official pages—captured the same day from the same domain—create uncertainty about both the starting price and the renewal rate. If Zappy's lower advertised figures prove accurate and stable, the program offers a cost advantage; if the step-up pricing applies, PlexusDx delivers lower 12-month costs and stable budgeting.

Commitment plans and flexibility

Zappy Health offers monthly billing only (based on captured evidence). PlexusDx offers month-to-month plans plus optional 3-month and 6-month commitment plans at reduced per-month rates, billed monthly over the commitment term. Readers seeking the lowest per-month floor may prefer a PlexusDx commitment plan; those prioritizing month-to-month flexibility should compare Zappy's advertised rate (if confirmed) against PlexusDx's $189 semaglutide or $289 tirzepatide month-to-month.

Regulatory and compounding disclosures

Both programs dispense compounded semaglutide and tirzepatide, which 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. Readers should confirm Zappy Health's pharmacy sourcing and regulatory compliance during intake.

Choose Zappy Health if…

• You verify at checkout that the advertised $159 semaglutide or $279 tirzepatide rate is the standard monthly price with no step-up, and you are comfortable with month-to-month billing only.
• You accept the documented pricing conflict and are willing to confirm renewal terms in writing before the first charge.
• The lower advertised rate, if confirmed stable, fits your budget better than PlexusDx's published rates.

Choose PlexusDx if…

• You want one published rate with no promotional period and no renewal increase—the advertised price is the ongoing price.
• You value commitment-plan discounts ($169/month semaglutide on a 3-month plan, $149 on 6-month; $269/$249 tirzepatide) while retaining monthly billing.
• You prefer a provider with a verified Trustpilot rating (4.3 stars, 79% five-star, 83% four-star or higher, captured September 9, 2026) and transparent published pricing on every product page.
• You want the same per-month price at every dose, with no dose-tier surcharges or hidden fees.

Methodology and freshness

Zappy Health pricing and plan terms were captured September 4, 2026, from zappyhealth.com landing pages and official program pages. The documented conflict—advertised $159/$279 on one page, "$199 first 3 months then $295" / "$299 first 3 months then $359" on another—was recorded from the same domain on the same date. No checkout completion was performed; prices reflect publicly displayed rates. PlexusDx pricing was captured September 12, 2026, from plexusdx.com product pages. PlexusDx's Trustpilot rating (4.3 stars, 79% five-star reviews, 83% four-star or higher) was captured September 9, 2026, from trustpilot.com/review/plexusdx.com. Zappy Health's Trustpilot profile exists but no rating or review volume was captured. All 12-month cost figures are our calculation based on the documented rates and represent total out-of-pocket spend assuming continuous monthly treatment. Readers should verify pricing, renewal terms, cancellation policies, and pharmacy sourcing at checkout before committing.

Frequently Asked Questions

Why does Zappy Health show two different prices for the same medication?

Zappy Health's official pages, captured the same day, display conflicting figures: one landing page shows advertised $159/month semaglutide and $279/month tirzepatide, while another official page states "$199 first 3 months then $295" for semaglutide and "$299 first 3 months then $359" for tirzepatide. The evidence does not clarify which structure applies or whether the lower figures are introductory. Confirm pricing and renewal terms at checkout.

Does PlexusDx charge a membership fee on top of medication cost?

No. PlexusDx charges one flat monthly rate ($189 semaglutide, $289 tirzepatide on month-to-month plans) with no separate membership, initiation, or ongoing subscription fee. The medication price includes the provider visit, prescription, medication, and shipping. Commitment plans (3-month and 6-month) offer lower per-month rates billed monthly over the term.

Which provider offers the lowest 12-month cost for semaglutide?

If Zappy Health's advertised $159/month rate is standard and stable, it totals $1,908 over 12 months vs PlexusDx $2,268 month-to-month (our calculation). If Zappy's "$199 then $295" structure applies, the 12-month cost climbs to $3,252—$984 more than PlexusDx. The official-page conflict means the economic winner depends on which rate Zappy actually charges at renewal.

Can I switch from one provider to the other mid-treatment?

Switching telehealth providers mid-treatment is possible but not guaranteed. A new provider's clinician must independently determine whether continuing the medication is appropriate, review your current dose and tolerance, and issue a new prescription. Dose continuity, timing, and formulary differences (especially salt forms in compounded products) are not assured. Confirm transfer policies and prescription-review timelines before canceling your current provider.

Are compounded semaglutide and tirzepatide FDA-approved?

No. 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. Both PlexusDx and Zappy Health dispense compounded GLP-1 agonists, not branded Ozempic, Wegovy, Mounjaro, or Zepbound. PlexusDx works with licensed 503A compounding pharmacies; confirm Zappy Health's pharmacy sourcing during intake.
