PlexusDx review
The lowest figure is a microdose protocol where the provider chooses both the molecule and the route.
The verdict
PlexusDx publishes a $129 microdose protocol, on which the provider selects the molecule and route. Its named semaglutide injection is $189 month to month and tirzepatide is $289.

PlexusDx sells named semaglutide and tirzepatide injections across fifty states, plus an entry microdose protocol that is not molecule-specific.
Who writes the prescription, and what do they see?
On the microdose protocol the prescriber decides what the plan contains. That is a real clinical choice and it means the $129 does not name a product a reader can compare.
Two structures run side by side. The named product lines carry their own ladders. The entry protocol carries a lower figure and an unnamed drug, which is a different kind of purchase.
What happens when the dose goes up?
The named lines publish term ladders rather than dose ladders. Nothing states what either figure does as milligrams rise, and the microdose protocol is a low weekly dose by design.
What the price includes
Semaglutide injection is $189 month to month, $169 on three months and $149 on six. Tirzepatide is $289 month to month, $269 on three months and $249 on six. Six months of semaglutide at the monthly rate is $1,134, or $894 on the six-month rung. The $129 microdose figure is all-inclusive and is not one of these products.
What it claims, and what it cites
All lines are compounded. A pharmacy prepares them. The FDA does not review them before dispensing. No pharmacy is named.
Where it holds up, and where it does not
- Strength: Three rungs published on both named lines
- Strength: Coverage across all fifty states
- Strength: The microdose protocol is labeled as one
- Strength: All figures described as all-inclusive
- Limitation: The entry figure names no molecule
- Limitation: Its route is chosen by the provider
- Limitation: No dose behavior is published
- Limitation: No compounding pharmacy is named
What the evidence says about this kind of treatment
The assessment above is about PlexusDx. These are about the drugs it sells, and they are traced to the primary literature.
- Right for
- A reader who wants a named product and will read past the entry card.
- Wrong for
- A reader comparing $129 against a named semaglutide price.
The evidence behind what PlexusDx prescribes
These studies examine the medicines, not this provider. Results with approved products do not establish the quality or effectiveness of a seller’s compounded formulation.
- Cochrane Review of Semaglutide for Obesity: 18 Trials Graded
A 2025 Cochrane review pooled eighteen randomized trials. The weight figure is high certainty and smaller than the marketing, and almost everything else is graded lower.
- Tirzepatide vs Semaglutide: Which Works Better for Weight Loss?
In a 72-week randomized trial at weight-management doses, weight fell 20.2 percent on tirzepatide and 13.7 percent on semaglutide. Routine-care studies found a smaller gap, three to four points.

- What does $129 buy?
- A microdose protocol on which the provider selects the molecule and the route. It is not a named product.
- What does the semaglutide injection cost?
- $189 month to month, $169 on three months and $149 on six.
- Is the $249 tirzepatide figure a monthly rate?
- It is the six-month rung. Month to month is $289 and three months is $269.
- Is PlexusDx legit?
- PlexusDx is a GLP-1 telehealth sellers service. Its stated availability: All 50 states. What our record does not establish: whether it bills insurance and how its intake works. Ask for those in writing before you pay.
- Is PlexusDx expensive compared with other GLP-1 telehealth sellers?
- PlexusDx publishes a starting figure of $189/mo. Across the 402 GLP-1 telehealth sellers we review that publish a single monthly figure, those run $49 to $525.42 with a median of $190, which puts PlexusDx below the median, toward the cheaper end. The other 178 GLP-1 telehealth sellers we review quote only after an intake or price by dose, so they are not in that comparison. A starting figure is not a bill — labs, consultations and shipping are often charged separately, so confirm what your own quote includes.
