Pharmacy transparency and genetic testing. What is actually dispensed, how the prescription works, and what the price really is — $189 a month.
Updated 2026-09-18
Disclosure: one company on this page — Coreage Rx — pays us a commission when a reader signs up through our link. It does not buy a better score, a higher ranking, or the removal of any criticism. The scoring rubric and the full disclosure are both published.
PlexusDx publishes six named 503A pharmacy partners and the NPI numbers of its prescribing physicians. No other programme in this comparison comes close on disclosure.
Belmar, Strive, Epiq Scripts, Casa Pharma Rx, The Pharmacy Hub and Foothills are all listed publicly, with phone numbers. Clinical oversight runs through LionMD with named physicians. Compounded injection pricing is $189 a month, no membership, same price at every dose.
The prescription, at a glance
What is actually supplied
Compounded tirzepatide from a state-licensed 503A pharmacy, typically delivered within five to seven business days. Because the pharmacies are named, you can look up their licensure yourself rather than taking a marketing page on trust — which is exactly what we tell readers to do.
How the prescription works
An independent U.S.-licensed clinician reviews your intake and writes the prescription if you are eligible; PlexusDx states the clinician is independent of the company. Available in all 50 states. A $189 microdose tier is offered separately and is a different treatment from full-dose therapy.
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.
Reading the price
$189 a month with no membership. The advertised "from $129" is the programme floor and does not describe the injection tier.
The $129 entry point is the programme floor; the published injection tier sits at $189 with no membership behind it.
What 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.
Checked 2026-09-18. Pricing here changes frequently; treat anything older than a month as a starting point rather than a quote.
Strengths
- 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.
Drawbacks
- 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.
Important. The advertised "from $129" is the programme floor. Budget $189/month for the compounded injection tier.
