PlexusDx offers all-inclusive compounded GLP-1 programmes from $129 a month, paired with optional genetic and blood testing including a panel covering GLP-1 response variants.

Overview

PlexusDx started as a consumer diagnostics company selling genetic and blood test panels, and has extended into prescription weight-loss and longevity programmes. The result is a wider catalogue than most GLP-1 telehealth providers: five weight-loss programmes, five longevity programmes covering NAD+, sermorelin, glutathione, GHK-Cu and PT-141, ten genetic test panels, nine blood panels and a supplement range.

The GLP-1 programmes are priced flat and all-inclusive. The Microdose GLP-1 Protocol is $129 a month, semaglutide injection starts at $149, tirzepatide injection at $249, oral semaglutide at $249 and oral tirzepatide at $279. In every case PlexusDx states that the provider, prescription, medication and shipping sit inside one monthly charge, with no membership fee, no consult charge and no increase as your dose changes.

The differentiator is the diagnostics layer. After your first month of treatment you can add a Precision Peptide Genetic Test for $99, analysing 34 weight-management insights drawn from a panel of more than 150 insights across 14 pathways, and specifically flagging GIPR rs1800437, a variant associated with differential GLP-1 response. It is a real scientific idea, though the clinical evidence that it should change how a GLP-1 is prescribed remains preliminary.

Medications Offered

What You Can Be Prescribed
  • Compounded microdose GLP-1, weekly injection at low dose
  • Compounded semaglutide injection
  • Compounded tirzepatide injection
  • Oral semaglutide and oral tirzepatide formulations
  • Longevity peptides including NAD+, sermorelin, glutathione, GHK-Cu and PT-141
  • No brand-name Ozempic, Wegovy, Mounjaro or Zepbound

Brand-Name or Compounded?

Compounded, prepared by a 503A compounding pharmacy to your provider's prescription. PlexusDx describes the pharmacy as a US partner pharmacy but does not name the facility. Because compounded medication is not FDA-approved, the identity and accreditation of the pharmacy is the single most useful thing a provider can disclose, and it is the gap here.

Consultation Process

1

Start the weight-loss intake

An online intake covering health history and goals, with separate intake flows for weight loss and longevity programmes.

2

Asynchronous provider review

Licensed providers in all 50 states review your intake, with most patients reviewed within one business day.

3

Programme selection and shipping

Your chosen programme ships cold-chain packed from a US partner pharmacy at one all-inclusive monthly price.

4

Optional genetic add-on

After your first month you can add the Precision Peptide Genetic Test for $99 to look at 34 weight-management insights.

Eligibility

  • Adults completing the PlexusDx weight-loss intake
  • Licensed providers available in all 50 states
  • Clinical eligibility determined by the reviewing provider
  • Specific BMI thresholds are not published
  • The genetic panel is only offered after your first month of treatment
  • Standard GLP-1 contraindications apply as assessed by the prescriber

Provider Involvement and Lab Requirements

Provider Involvement

Licensed providers in all 50 states review intakes asynchronously, with most patients reviewed within one business day. PlexusDx states that monthly check-ins and variant adjustments are made based on your response and tolerance, and, importantly, that each refill is re-authorised by your provider rather than auto-shipped. That last detail is a genuine safety feature compared with auto-renewing shipments.

Lab Requirements

Not required and not included in the GLP-1 programme price. PlexusDx does sell standalone blood panels covering diabetes and heart health, hormones, cortisol and DHEA, nutrition deficiency and methylation, so baseline labs are available for purchase separately if you want them.

Pharmacy Fulfillment and Shipping

Pharmacy Fulfillment

Described but not named. PlexusDx states that medication is 503A compounded, prepared to your provider's prescription and shipped cold-chain packed from a US partner pharmacy. For a company built on diagnostic transparency, naming the compounding facility would be a natural extension and is the most obvious missing disclosure.

Shipping Frequency

Direct-to-door and cold-chain packed, shipped from a US partner pharmacy and included in the monthly price. Refills are provider-reviewed and re-authorised rather than shipped automatically, so you should expect to confirm each cycle rather than assume continuity.

Support Services

  • Monthly check-ins with dose adjustments based on response and tolerance
  • Provider-reviewed refills rather than automatic shipments
  • Cancel anytime with no long-term contract; pause or stop between refills
  • A GLP-1 support portal and a separate peptides support portal
  • An extensive published education library on GLP-1 and genetics
  • Optional genetic and blood testing to add context to treatment

Pricing

PlexusDx publishes a price for every programme, all all-inclusive and all flat across dose levels. Nothing is bundled behind a membership.

Plan or MedicationPublished PriceWhat It Covers
Microdose GLP-1 Protocol$129/moProvider, prescription, medication and shipping, all doses

Membership feeNoneNo membership, consult charge or hidden fees

Pricing reflects what PlexusDx published at the time of review and can change without notice. Confirm current pricing directly with the provider before enrolling.

Membership Fees

None. PlexusDx explicitly lists membership fee, consult charge and hidden fees under what you will not pay, and states that provider, prescription, medication and shipping are covered by the single monthly charge.

Medication Fees

Included in the programme price, and flat across dose levels. PlexusDx frames this as your dose may need to go up but your price will not, which is the same flat-per-dose structure the better providers in this category have converged on.

Cancellation and Refund Policy

Cancellation

Cancel anytime with no long-term contract. Because refills are provider-reviewed and re-authorised rather than auto-shipped, you can also pause or stop between refills without cancelling outright, which is a more flexible arrangement than a standing subscription.

Refunds

PlexusDx does not publish detailed refund terms for its prescription programmes on its product pages. Compounded medication that has been prepared cannot generally be returned, so ask specifically what happens if you stop after a provider has authorised a refill but before it ships.

Insurance, HSA and FSA

Insurance

Not accepted for the prescription programmes, which are priced as cash-pay all-inclusive monthly charges.

HSA / FSA

PlexusDx does not publish an explicit HSA or FSA position on its GLP-1 product pages. Ask before purchasing if you intend to use pre-tax funds, and keep itemised receipts distinguishing the prescription programme from any test kits or supplements, which may be treated differently.

For a fuller explanation of how these accounts work with GLP-1 care, see our GLP-1 insurance, HSA and FSA guide.

Who PlexusDx May Be Best For

May Be a Good Fit If
  • You are curious about microdosing and want it priced as its own programme
  • You want an oral GLP-1 option alongside injectables from one provider
  • You want baseline blood or genetic testing from the same place
  • You want refills reviewed by a provider rather than auto-shipped
  • You want one flat price through titration
  • You are already a PlexusDx testing customer
Limitations to Weigh
  • The compounding pharmacy is not named
  • Genotype-guided GLP-1 dosing is an early idea, not established practice
  • The genetic panel is only sold after your first month of treatment
  • Tirzepatide at $249 is mid-market rather than competitive on price
  • No labs required or included in the programme price
  • A very broad catalogue, which can make the clinical offering harder to evaluate

Frequently Asked Questions

How much does PlexusDx cost?

The Microdose GLP-1 Protocol is $129 a month. Semaglutide injection starts at $149, tirzepatide injection at $249, oral semaglutide at $249 and oral tirzepatide at $279, all all-inclusive with no membership fee.

What is the PlexusDx genetic test?

An optional $99 Precision Peptide Genetic Test available after your first month of treatment, analysing 34 weight-management insights from a panel of more than 150 insights across 14 pathways, including GIPR rs1800437, a variant associated with differential GLP-1 response.

Should genetics change my GLP-1 dose?

Not on its own. Research linking specific variants to GLP-1 response is early rather than settled, and no major guideline recommends genotype-guided GLP-1 dosing. Treat the panel as context to discuss with your provider, not as a basis for changing treatment.

Does the price increase as my dose goes up?

No. PlexusDx states your monthly price does not change as your dose changes, and that the same price applies at every dose level.

Are refills automatic?

No. PlexusDx states that each refill is re-authorised by your provider and is not auto-shipped, and that you can pause or stop between refills.

Which pharmacy compounds PlexusDx medication?

PlexusDx describes it as a 503A compounded preparation shipped cold-chain packed from a US partner pharmacy, but does not name the facility.

Does PlexusDx require lab work?

No. Labs are neither required nor included in the programme price, though PlexusDx sells standalone blood panels separately if you want baseline testing.

Our Verdict

PlexusDx is the rare GLP-1 provider with a genuinely different proposition rather than a different price. It runs conventional all-inclusive compounded programmes at flat per-dose pricing, then layers on diagnostics: a $99 pharmacogenomic panel covering 34 weight-management insights including GIPR rs1800437, a variant associated with differential GLP-1 response. The science of genotype-guided GLP-1 dosing is early rather than settled, so treat the panel as interesting context rather than clinical direction, and judge the underlying programme on its own terms.
