PlexusDx semaglutide review
Pharmacy transparency and genetic testing. How they handle your dose ladder, what support looks like when side effects hit, and what you actually pay — $189 a month.

How we are paid: one company on this page — Coreage Rx — pays us a commission if you sign up through our link. It does not buy a better score, a higher position, or the removal of a single criticism. Our rating method and full disclosure are both public.
Compounded semaglutide at $189 a month, flat at every dose, from the only programme here that publishes all six of its compounding pharmacies.
That is more than the $99 leaders. What the extra buys is the ability to verify the supply chain — Belmar, Strive, Epiq Scripts, Casa Pharma Rx, The Pharmacy Hub and Foothills are all named, as are the prescribers.
How the dose ladder is handled
Standard 0.25 to 2.4 mg ladder with no price movement across it, and clinician review rather than automatic escalation.
| Semaglutide doses | Step up roughly every |
|---|---|
| 0.25 mg → 0.5 mg → 1 mg → 1.7 mg → 2.4 mg | 4 weeks |
| Price changes as you climb? | Check before you start |
The full schedule, and what to do if a rung goes badly, is in the dose ladder explained.
Support when it gets hard
Independent clinician oversight, ongoing check-ins, and a documented pharmacy chain. For anyone who has read the FDA warning letters and felt uneasy, this is the reassurance that is actually worth something.
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.
What it costs
About $2,268 a year with no membership fee behind it.

Checked 2026-09-18. Prices here move often, so treat anything older than a month as a starting point.
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.
Worth knowing. The advertised "from $129" is the programme floor. Budget $189/month for the compounded injection tier.
How it scored
PlexusDx scores 4.4 out of 5, placing it 3 of 17 for semaglutide. The weights are published on how we rate and fixed before we assess anyone.
| What we weigh | Weight | Score |
|---|---|---|
| True monthly cost | 30% | 4.6 / 5 |
| Price honesty | 20% | 4.5 / 5 |
| Clinical support | 20% | 3.8 / 5 |
| Pharmacy sourcing | 15% | 4.9 / 5 |
| Cancelling | 15% | 4 / 5 |
Our verdict
You are paying roughly $1,000 a year more than the floor for a supply chain you can check. In 2026 that is a defensible thing to buy.
