The short answer

Form Health charges $299/month for physician and dietitian care but bills medication and laboratory work separately; you pay retail or use insurance for Zepbound, Wegovy, Saxenda, or other FDA-approved drugs. PlexusDx charges $189–$289/month (month-to-month) for compounded GLP-1 medication plus clinician oversight and support in one fee, with no separate membership. Total 12-month cost at Form Health depends on your medication insurance coverage and lab frequency—variables this article cannot estimate. At PlexusDx, 12 months of compounded semaglutide injection runs $2,268 all-in on the month-to-month plan, $1,788 on the six-month prepaid plan; compounded tirzepatide injection runs $3,468 month-to-month, $2,988 prepaid (our calculation). Form Health's clinical service alone costs $3,588 over 12 months before any medication or lab expenses. The core trade-off: FDA-approved branded drugs with separated costs versus compounded medications with bundled pricing.

Form Health pricing breakdown: membership plus medication

Form Health charges $299 per month for its clinical service, which includes access to an obesity-medicine physician, a dietitian, and messaging support. That $299 does not cover medication or laboratory work; both are billed separately. Patients fill prescriptions for FDA-approved drugs—Zepbound (tirzepatide), Wegovy (semaglutide), Saxenda (liraglutide), and other approved options—through retail pharmacies or insurance, and pay whatever their plan or cash price dictates. Lab costs similarly depend on insurance coverage and provider rates.

Over 12 months the membership fee totals $3,588 (our calculation: $299 × 12). Medication and lab expenses add to that figure but vary widely by drug, dose, insurance, and lab frequency, making a complete 12-month total unknowable without patient-specific data. A month of branded semaglutide or tirzepatide at retail can range from hundreds to over a thousand dollars without coverage.

PlexusDx pricing breakdown: medication and care bundled

PlexusDx charges a single monthly fee that includes compounded medication, clinician oversight, support, and lab interpretation—no separate membership. Month-to-month rates as of September 5, 2026:

• Compounded semaglutide injection: $189/month
• Compounded tirzepatide injection: $289/month
• Compounded semaglutide oral: $289/month
• Compounded tirzepatide oral: $349/month
• Microdose GLP-1 injection: $129/month

Prepaid plans reduce the per-month rate: semaglutide injection drops to $169/month on a three-month plan and $149/month on a six-month plan; tirzepatide injection falls to $269/month (three-month) and $249/month (six-month). Oral and microdose options carry similar prepaid discounts.

Over 12 months, month-to-month compounded semaglutide injection totals $2,268 ($189 × 12, our calculation), while six-month prepaid reduces that to $1,788 ($149 × 12, our calculation). Compounded tirzepatide injection runs $3,468 month-to-month ($289 × 12, our calculation) or $2,988 on the six-month plan ($249 × 12, our calculation). Those figures include medication, clinician time, support, and lab review; no line item is separated.

Apples-to-apples 12-month comparison

Direct cost comparison between Form Health and PlexusDx is impossible because Form Health's medication expense is unknown and patient-specific. The table below shows what is knowable: the clinical service cost at Form Health, the all-inclusive cost at PlexusDx, and the medication gap.

Our calculation: Form Health $299/month × 12 = $3,588; PlexusDx semaglutide $189 × 12 = $2,268, tirzepatide $289 × 12 = $3,468.

If a Form Health patient's insurance covers most of their branded medication cost—say a $25 copay per month—and labs run $100 quarterly, the 12-month add-on is roughly $700, bringing the total to around $4,288. If medication is paid at retail (often $1,000+ per month for Wegovy or Zepbound without coverage), the 12-month total can exceed $15,000. That wide range makes Form Health more expensive than PlexusDx for most self-pay patients, less expensive for patients with excellent drug coverage, and impossible to generalize without knowing the individual's insurance situation.

FDA-approved versus compounded medications

Form Health prescribes only FDA-approved brand-name drugs: Zepbound and Wegovy (the GLP-1 receptor agonists approved specifically for weight management), Saxenda (an older GLP-1), and other approved options. These drugs have completed Phase III trials, carry FDA-reviewed labeling, and are manufactured under current Good Manufacturing Practices with batch testing and traceability.

PlexusDx offers compounded semaglutide and tirzepatide—custom-prepared formulations of the same active pharmaceutical ingredients found in Wegovy (semaglutide) and Zepbound (tirzepatide), but produced by 503A compounding pharmacies rather than the brand manufacturers. 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.

Patients who prefer or require FDA-approved drugs—because of employer or insurance requirements, personal preference for brand manufacturing, or clinical history—will find only Form Health meets that need in this comparison. Patients prioritizing cost transparency and all-inclusive pricing may prefer PlexusDx's compounded model, accepting that compounded drugs lack the FDA's premarket safety and efficacy review.

Clinical team structure

Form Health pairs every patient with an obesity-medicine physician (a doctor with board certification or fellowship training in obesity medicine) and a registered dietitian. Both clinicians are accessible via messaging, and the $299/month membership covers ongoing consultations, dose adjustments, and nutrition counseling without per-visit fees.

PlexusDx assigns a licensed healthcare provider—physician, nurse practitioner, or physician assistant depending on state scope-of-practice rules—who prescribes medication, interprets labs, and adjusts treatment. Dietitian consultation is not part of the standard service but patients receive dosing guidance and side-effect management as part of the included clinical oversight. The model is medication-centered rather than intensive behavioral intervention.

Form Health's dual-clinician model offers more comprehensive nutrition and behavioral support; PlexusDx's single-provider model keeps the cost lower and medication access simpler. Neither structure is categorically better—choice depends on whether you want dedicated dietitian time or prefer a streamlined prescribing relationship.

What the $299 membership includes and excludes

Form Health's $299/month fee covers:

• Physician consultations and messaging
• Dietitian consultations and messaging
• Treatment plan development and adjustment
• Prescription writing (but not the prescription cost itself)

It does not cover:

• Medication cost (you pay separately at pharmacy or via insurance)
• Lab work and lab interpretation fees (you pay the lab or your insurer's lab benefit)
• Any retail pharmacy dispensing fees or shipping for medication

Patients should budget for medication and lab expenses on top of the $299 monthly membership. Form Health does not publish medication pricing because costs depend entirely on the patient's insurance formulary, pharmacy benefit manager, and retail pharmacy rates.

What PlexusDx's fee includes

PlexusDx's $189–$349/month fee (depending on compound and route) covers:

• Compounded GLP-1 medication shipped to your door
• Licensed clinician consultation, prescription, and ongoing oversight
• Lab review and interpretation (patient arranges lab draw locally or via mail-order kit)
• Messaging support for side effects, dose questions, and refills
• Dose escalation at the same monthly price (no upcharge as dose increases)

Nothing is billed separately. If a dose adjustment or formulation change is needed, the clinician handles it within the same monthly fee. PlexusDx holds a 4.2-star rating on Trustpilot, with 76% of reviews at five stars and 81% at four stars or higher (captured September 4, 2026).

Insurance and self-pay positioning

Form Health accepts insurance for its clinical service and helps patients use their pharmacy benefits for medication. If your insurance covers obesity medicine visits and has favorable Wegovy or Zepbound coverage—common in 2026 for patients with BMI ≥30 or ≥27 with comorbidity—Form Health's model can be cost-effective, particularly if your plan pays most of the $299 clinical fee and your medication copay is low.

PlexusDx is a self-pay-only model. No insurance is billed; no prior authorizations are required; no formulary restrictions apply. Patients pay the posted monthly rate by credit card or HSA/FSA card. The trade-off: you lose insurance leverage but gain pricing certainty and faster access (no prior-authorization delays).

If you have strong insurance coverage, run the numbers with Form Health's $299/month plus your medication copay and lab costs. If you're self-pay or your insurance denies or delays GLP-1 coverage, PlexusDx's bundled rate may be simpler and cheaper.

Choose Form Health if…

• You require or strongly prefer FDA-approved brand-name medications (Wegovy, Zepbound, Saxenda) over compounded alternatives.
• Your insurance covers obesity-medicine physician visits and has favorable pharmacy benefits for GLP-1 drugs, making the out-of-pocket cost of medication low.
• You want dedicated dietitian support as part of your clinical team, included in the monthly fee.
• You're comfortable with a separated billing model (membership separate from medication and labs) and can budget for variable monthly costs depending on dose and insurance.
• You prioritize a physician with specialized obesity-medicine credentials rather than a general-practice prescriber.

Choose PlexusDx if…

• You want transparent, all-inclusive monthly pricing with medication, clinical oversight, and labs bundled into one fee.
• You're paying out-of-pocket and prefer a lower, predictable monthly cost ($189–$289 for injectable GLP-1s) rather than navigating retail medication pricing.
• You're comfortable with compounded medications prescribed by a licensed provider, understanding they are not FDA-approved and lack the premarket review of branded drugs.
• You don't need intensive dietitian counseling and prefer a streamlined medication-management relationship.
• You want the same monthly price regardless of dose, avoiding unexpected cost jumps as your treatment progresses.

Frequently Asked Questions

Does Form Health's $299/month include medication?

No. The $299 monthly membership covers physician and dietitian care, messaging support, and prescription writing. Medication and lab work are billed separately; you pay retail prices or use insurance at a pharmacy. Total monthly cost depends on your drug coverage and dose.

Is PlexusDx's pricing really all-inclusive or are there hidden fees?

PlexusDx's posted monthly rate ($189–$349 depending on compound and route) includes medication, clinician oversight, lab review, support, and shipping. No membership fee, no per-visit charges, no dose-escalation upcharges. The monthly rate is the total recurring cost.

Can I use insurance with either service?

Form Health works with insurance for clinical visits and helps patients use pharmacy benefits for FDA-approved medications. PlexusDx is self-pay only; no insurance is billed. If you have strong insurance drug coverage, Form Health may cost less; if you're uninsured or your plan denies GLP-1s, PlexusDx's flat rate may be simpler.

What's the difference between compounded and FDA-approved GLP-1 medications?

FDA-approved drugs (Wegovy, Zepbound) completed Phase III trials, carry FDA-reviewed labeling, and are manufactured under strict federal oversight. Compounded medications use the same active ingredients but are prepared by 503A pharmacies without FDA premarket review for safety, effectiveness, or quality. A licensed clinician determines appropriateness for each patient.

Which service is cheaper over 12 months?

PlexusDx compounded semaglutide runs $2,268/year month-to-month, $1,788 prepaid; tirzepatide runs $3,468 month-to-month, $2,988 prepaid. Form Health's clinical service costs $3,588/year before medication and labs. If your medication is covered by insurance with a low copay, Form Health may be competitive; if you pay retail for branded drugs, PlexusDx will likely cost thousands less annually.
