PlexusDx semaglutide review

Pharmacy transparency and genetic testing. We checked the advertised price against what you are actually billed. True cost: $189 a month.

Updated 2026-09-18 · Prices verified independently

Why you can trust this: we take payment from one company on this page — Coreage Rx — when a reader signs up through our link. It does not change the prices we print or the rubric we score against, both of which are published in full on how we rate. Read our full disclosure.


Compounded semaglutide at $189 a month, no membership, the same price at every dose, from a company that names all six of its compounding pharmacies.

That is more than the $99 leaders and considerably less than the mid-market programmes once their fees renew. What you are paying the difference for is verifiability: Belmar, Strive, Epiq Scripts, Casa Pharma Rx, The Pharmacy Hub and Foothills are all listed publicly, as are the prescribing physicians.

What you will actually pay

Semaglutide at PlexusDx
Advertised from$129/mo
Ongoing medication$189/mo
Membership or platform feeNone
True monthly cost$189/mo
Roughly, over a year$2,268

No membership fee, and the price does not change as the dose is adjusted.

About $2,268 a year. Coreage Rx on the annual plan is about $1,188 and Trimi the same, so PlexusDx is not the cheapest — it is the most transparent.

How PlexusDx works

Prescription GLP-1 and peptide programmes with no membership fee, built around genetic testing, using independent clinicians and a publicly listed set of 503A pharmacies.

Intake, independent clinician review, then shipping from a state-licensed 503A pharmacy. A $189 microdose tier is also offered, which is a different treatment from full-dose therapy and should not be compared with it on price.

The facts we verified

  • GLP-1 weight-loss programmes start at $129/month.
  • Compounded semaglutide injection listed at $189/month with no membership fee and the same price at every dose.
  • A $189/month microdose tier is offered for compounded semaglutide or tirzepatide.
  • No membership or platform fee is charged alongside the medication.
  • Publicly names six 503A pharmacy partners: Belmar, Strive, Epiq Scripts, Casa Pharma Rx, The Pharmacy Hub and Foothills.
  • Clinical oversight via LionMD, with named physicians and NPI numbers published.
  • Licensed providers in all 50 states; CLIA-certified labs for its testing line.

Every figure above was checked on 2026-09-18. Pricing in this market moves, so treat anything older than a month as a starting point rather than a quote.

Where it is strong

  • The most detailed pharmacy disclosure in this comparison — six named 503A partners.
  • Names its prescribing physicians along with their NPI numbers.
  • No membership fee, and flat pricing across the dose range.
  • Genetic and blood testing available alongside the prescription.

Where it falls short

  • The genetics-led positioning adds cost and complexity some people will not want.
  • The $129 figure is a programme floor rather than the injection price.
  • Weight care sits alongside a broad longevity and supplement line rather than being the sole focus.

The thing most people miss

The advertised "from $129" is the programme floor. Budget $189/month for the compounded injection tier.

How it scored

Who it suits

Someone who wants the compounding question answered properly and will pay a premium for that. Not the pick for the lowest possible monthly cost.

Our verdict

You are buying disclosure. If the 2026 regulatory picture worries you, that is a rational thing to spend money on.
