PlexusDx sells compounded semaglutide at $149 a month and compounded tirzepatide at $189, as weekly injections or daily tablets, plus a microdose GLP-1 plan at $99. One price covers the visit, drug and shipping, and it does not rise with the dose; prepaying a year cuts the rate to $99 and $129. Lone Star Virtual Health prescribes and Vials RX in Texas fills. An optional genetic test is $99 after the first month.

Is PlexusDx legit?
Yes. PlexusDx is a real, operating US company, and we found no FDA warning letters issued to it. We rate it 8.0/10 overall, across six areas from price to trust and safety. Legitimate is not the same as right for you, though: that part is a decision for you and a licensed clinician.
Is there a PlexusDx promo or coupon code?
We know of no promo or coupon code for PlexusDx. Its listed price is $99 a month. Coupon sites advertising "PlexusDx discount codes" are not a source we can vouch for, and any genuine offer shows at checkout without a code.

How PlexusDx scores
Six columns, each one computed from something PlexusDx has published rather than from an opinion we formed: what it charges, which molecules it will dispense, what its record shows, and what the monthly figure actually buys. Where a seller keeps something back, such as its price or its pharmacy, the score reflects it. Every seller we review goes through the same six columns.

What signing up with PlexusDx involves
What to expect on the way to a prescription: where the price appears, who fills the medication, and what the monthly price covers. It is not medical advice, and a clinician makes the prescribing decision.
- 1PlexusDx shows a price on its own site before asking anything about you, so you can compare it with other sellers before you start a questionnaire.
- 2Vials RX fills the prescriptions, and PlexusDx names it publicly, which most sellers do not.
- 3The monthly price includes the medication, clinician visits and shipping.
Price shown before you start
- Lowest ongoing monthly price: semaglutide $149, tirzepatide $189. That leaves out membership fees, first-month rates and insurance copays.
- Confirm that PlexusDx serves your state before you start.
- The medication is compounded, so it is not an FDA-approved product and has not been reviewed by the agency for safety, effectiveness or manufacturing quality.

Check the price yourself before you pay
Every figure here comes from PlexusDx's own website, as of the date shown. Sellers move prices without announcing it, and promotional rates lapse, so confirm the standing cost on their site before committing.
PlexusDx compounding-pharmacy partners
PlexusDx names each pharmacy below as one that compounds or fills its prescriptions, in its own site, terms or filings. The quote under each one is the seller’s own wording.
In its favor
- Semaglutide costs $149 a month, 25% below the $199 median for compounded semaglutide across the sellers we compare
- Tirzepatide costs $189 a month, 30% below the $269 median for compounded tirzepatide across the sellers we compare
- Shows its price before the medical questionnaire, so you can compare it without handing over health information
- The monthly price stays the same as your dose goes up
- The monthly price includes the medication, clinician visits and shipping
- Names Vials RX as the pharmacy that fills its prescriptions, which most sellers do not
- We found no FDA warning letters issued to PlexusDx
Against it
- Confirm it serves your state before you start the intake
- Its semaglutide and tirzepatide are compounded rather than FDA-approved, so they have not been reviewed by the agency for safety, effectiveness or manufacturing quality
What PlexusDx charges
PlexusDx charges $99/month for its microdose tier; its standard plans start at $149/month and hold that rate across every dose.
- Microdose GLP-1, month to month: $99/month
- Compounded semaglutide (injection): $149/month
- Compounded semaglutide (tablet): $149/month
- Compounded tirzepatide (injection): $189/month
- Compounded tirzepatide (tablet): $189/month
For compounded tirzepatide, the median across the sellers we compare is $269/month, so PlexusDx's $189 is genuinely below the middle, not just advertised that way. Before you pay, compare PlexusDx's cancellation terms with other sellers' cancellation and refund policies.
AgelessRx, at about $99/month, is the closest like-for-like alternative we review.
What PlexusDx dispenses
PlexusDx prescribes semaglutide (approved as Wegovy and Ozempic) and tirzepatide (approved as Zepbound and Mounjaro). Between them these are the pair carrying the strongest published outcome data. What arrives is compounded at a licensed pharmacy, not an approved pen. That is the reason it costs less, and the reason the finished preparation carries no FDA review behind it. The molecule can be the one in Ozempic and Wegovy; what differs is the formulation, the concentration and the dose ladder. PlexusDx also lists a microdose plan, and the published evidence on GLP-1 microdosing is letters and commentary rather than trials.
A needle-free oral option is genuinely uncommon and is the reason some readers will look at PlexusDx at all. Set expectations on the evidence, though: the published weight-loss trials for these molecules used injections. Oral and sublingual delivery of peptides is far less studied, so treat it as a route that solves the needle problem rather than as a proven equal to the shot.
Safety and disclosure
PlexusDx tells you its price before you start the medical questionnaire and the pharmacy that fills its prescriptions. We found no FDA warning letters issued to PlexusDx. Because the medication is compounded, the named pharmacy is the detail that matters most: its license is the one you can look up. The FDA's warning signs for online medicine sellers are a quick check to run on any seller before you pay. How we weigh oversight, disclosure and price is set out in our scoring methodology.
PlexusDx also sells NAD+, and a 2026 systematic review found no outcomes trials of injected NAD+ for anti-aging or wellness.
Who should look elsewhere
- You want the FDA-approved pen specifically. Everything listed here is compounded.
- You need insurance to cover the cost. Check whether PlexusDx bills your plan before you start.
It fits if
- the lowest standing monthly cost is what you are solving for
- you want the price to stop moving as your dose climbs
- injections are the thing keeping you from starting
Our read
PlexusDx competes on price without an obvious sacrifice elsewhere: $189/month for compounded tirzepatide, no FDA warning letters.
The Bottom Line
PlexusDx scores highest on the clinical side (which drugs it prescribes and how it doses) and lowest on availability. It charges from $99 a month; its compounded tirzepatide, at $189, is 30% below the $269 median among the sellers we compare.

Where PlexusDx is the wrong choice
No seller suits every reader, and pretending otherwise is the easiest way to sell one. On these three counts, another seller does better.
- If you need the FDA-approved pen rather than a compounded vial, consider WellMedRx.
- If the standing monthly cost is what decides it, consider Collective (from $59/mo + membership).
- If you want a human checking in, not just a prescription, consider Eden.
If none of these fits, our guide to alternatives to PlexusDx sets more sellers in the same category beside PlexusDx on price, states and what the price includes.

Frequently Asked Questions
PlexusDx sells compounded semaglutide at $149 a month and compounded tirzepatide at $189, as weekly injections or daily tablets, plus a microdose GLP-1 plan at $99. One price covers the visit, drug and shipping, and it does not rise with the dose; prepaying a year cuts the rate to $99 and $129. Lone Star Virtual Health prescribes and Vials RX in Texas fills. An optional genetic test is $99 after the first month. We rate it 8.0/10 overall.
PlexusDx starts at $99 a month, but that is for its microdose tier; its standard injectable starts at $149. The pricing table above lists every tier.
Ask PlexusDx whether it serves your state before you start the intake, and get the answer in writing.
PlexusDx lists compounded semaglutide and compounded tirzepatide. A needle-free oral form is listed as well.
PlexusDx lists compounded GLP-1s only. A licensed compounding pharmacy prepares them: same active ingredient as the brand drug, lower cash price, and no FDA approval of the finished product. That last part is the one readers underestimate, and the review above says why.
Check whether PlexusDx bills your insurance before you sign up. Compounded GLP-1s are rarely covered by insurance, so plan on paying the listed cash price.
PlexusDx says the price covers medication, the clinician visit and shipping. The strip near the top of this review shows what is included and what is not.
You fill in an online intake, a licensed clinician decides whether a GLP-1 is appropriate, and if the answer is yes the medication ships to you. PlexusDx runs that whole sequence on its own site.
We found no FDA warning letters issued to PlexusDx. Before you buy, weigh these: Confirm it serves your state before you start the intake. Its semaglutide and tirzepatide are compounded rather than FDA-approved, so they have not been reviewed by the agency for safety, effectiveness or manufacturing quality. None of them rules PlexusDx out, but each is worth settling before you pay.
Other sellers we cover include SnagRx, Lttl, and YourEra. Which one fits depends on the medication, the monthly price you can sustain and whether it ships to your state, so compare those three facts before you switch.
