Trimi vs PlexusDx
$125/mo against $189/mo for tirzepatide. Which is worth it, and for whom.
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.
Both sell tirzepatide. Trimi costs $125 a month and PlexusDx costs $189, a difference of $64 a month or about $768 a year. Here is what that difference actually buys.
Trimi is lowest flat price with named pharmacies. PlexusDx is pharmacy transparency and genetic testing. They are not aimed at the same person, and the cheaper one is not automatically the right answer — though it usually is if you are paying cash and tolerate the medication well.

Where Trimi wins
- The cheapest verified flat rate for compounded tirzepatide in this comparison.
- Names its pharmacies with a licence number and offers a certificate of analysis — almost nobody else in this market does.
- Price does not move as your dose is adjusted.
- No membership fee stacked on the medication price.
Both headline prices are annual-plan rates. Confirm the month-to-month figure and the refund terms before prepaying twelve months.
Where PlexusDx wins
- 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.
The advertised "from $129" is the programme floor. Budget $189/month for the compounded injection tier.

Which should you pick?
- Pick Trimi if cost is the binding constraint. Over a year the gap is about $768, which is real money for the same class of medication.
- Pick PlexusDx if what it does better matters to you — the most detailed pharmacy disclosure in this comparison — six named 503a partners.
- If sourcing matters, note that Trimi publishes which pharmacy compounds its medication and PlexusDx does not.
The verdict
For most cash payers, Trimi at $125 a month is the more defensible choice on arithmetic alone. PlexusDx earns its premium only if you will actually use what it does differently. Read the full reviews before deciding: Trimi and PlexusDx.
