Our verdict
PlexusDx is easy to misfile as a DNA-testing company, and it is not.
Main trade-offs
- NAD⁺ and sermorelin "from $129" is the six-month rate; month-to-month is $179
- The genetics positioning describes a $99 add-on sold after your first month, not an input to your prescription

Good fit
People who want sermorelin, NAD⁺, glutathione or GHK-Cu at a published all-in monthly price with monitoring folded in and no membership on top.
Consider other options if
Anyone expecting genetics to shape their prescription without paying extra, who needs the dispensing pharmacy named, or who will not commit beyond month-to-month.

Our review in detail
Full assessment
PlexusDx is easy to misfile as a DNA-testing company, and it is not. Underneath the "built around your genetics" positioning sits a conventional prescription peptide service with five longevity protocols and a published all-in monthly price on each: NAD⁺ and sermorelin from $129, glutathione at $125, GHK-Cu Rx at $139 and PT-141 at $189. Consultation, medication, shipping and ongoing provider monitoring are stated as included, which is what "all-inclusive" should mean. Read the NAD⁺ and sermorelin figures carefully, though: $129 is the six-month commitment rate, and month-to-month is $179. The genetics part is a $99 add-on offered after your first month — an upsell, not an input to your prescription.
What it is
PlexusDx is a US telehealth platform running two prescription lines alongside a genetic-testing and blood-testing business. Weight loss covers five compounded GLP-1 protocols — a microdose GLP-1 from $129/mo, semaglutide from $149/mo and tirzepatide from $249/mo, in injection or oral form. Longevity covers five single-compound protocols: NAD⁺ (injection, nasal spray or a dissolving tablet), sermorelin (injection or orally disintegrating troche), glutathione (nasal spray or troche), GHK-Cu Rx as a topical cream, and PT-141. Its genetic side sells methylation, peptide-pathway and other reports from a cheek swab. A licensed clinician from an independent network reviews each intake, and compounded medication comes from licensed 503A pharmacies.
How care works
Asynchronous in most states, program-shaped, and clearer than most about what a price covers. Each protocol is labeled all-inclusive — consultation, prescription, medication, shipping, ongoing provider monitoring and provider-reviewed refills — with no membership fee, and it states that five states require a live video consultation while the rest allow an online intake. It displays an HSA/FSA payment option through Flex and says you can cancel from a self-service portal before your next billing cycle, with no fee. Two things to keep in view. First, the genetics framing does real work in the marketing and very little in the care pathway: the Precision Peptide genetic test is sold as a $99 add-on against a $298 list price, offered after your first month of treatment, so nothing about your initial prescription is genetically informed unless you separately buy in. Second, the compounding pharmacies are never named — only described as licensed 503A pharmacies — and no individual clinician or medical director is published. Its own fine print also notes that medication and clinical fees are billed by the practice-management platform behind the prescribers rather than by PlexusDx itself, so expect that name on your card statement.
Costs, billing and cancellation
Published per protocol and stated as all-inclusive. NAD⁺ and sermorelin are each priced by commitment tier: $179 a month month-to-month, $149 on a three-month commitment and $129 on six months, the same price at every dose and in every formulation. Glutathione is a flat $125, GHK-Cu Rx a flat $139 and PT-141 a flat $189. The Longevity headline, "starts at $125/mo", is the glutathione price. A GETSTARTED code takes 10% off a first protocol for new patients. On the weight-loss side, protocols run $129 to $279 a month at their best commitment tier — but those are GLP-1 figures and are not peptide or NAD⁺ prices. The genetic test is a separate $99 charge after your first month, discounted from a stated $298; treat that as an add-on, not as a bundled benefit. Ask what the monthly shipment contains, since neither dose nor vial size is stated beside any protocol price.
Medication and evidence
Compounded; not FDA-approved. Prescription required only if a licensed provider finds it appropriate. PlexusDx states in its own words that its compounded medications are not FDA-approved and have not been evaluated by the FDA for safety, efficacy or quality, that it does not sell branded medication (though a provider can write a branded prescription for you to fill elsewhere), and that medication comes from licensed 503A pharmacies — none of which it names. Compounded sterile products are not reviewed by the FDA for purity and potency the way approved drugs are. On evidence, the five longevity protocols are not five equivalent purchases. Sermorelin is a GHRH analog with a real mechanism and thin long-term human outcome data. Injected and intranasal NAD⁺ have no controlled human outcome trials; the oral precursors NR and NMN are the forms with human data and they raise a blood level. GHK-Cu and glutathione have essentially no controlled human outcome data. PT-141 is approved for one narrow indication in premenopausal women, so other prescribing is off-label. Individual results vary.
Pros and watch-outs
What we like
- Five named longevity protocols, each with a published all-inclusive monthly price
- Glutathione $125, GHK-Cu Rx $139 and PT-141 $189 flat, with monitoring and refills stated as included
- States plainly that its compounded medications are not FDA-approved or FDA-evaluated
- Licensed providers claimed in all 50 states, with the five video-required states disclosed as a group
- No membership fee, HSA/FSA through Flex, and self-service cancellation
Watch-outs
- NAD⁺ and sermorelin "from $129" is the six-month rate; month-to-month is $179
- The genetics positioning describes a $99 add-on sold after your first month, not an input to your prescription
- Specific compounding pharmacies are never named
- No individual clinician or medical director published, and no enumerated state list
- Dose and vial size are not stated beside any protocol price
Best for
People who want sermorelin, NAD⁺, glutathione or GHK-Cu at a published all-in monthly price with monitoring folded in and no membership on top.
Who should look elsewhere
Anyone expecting genetics to shape their prescription without paying extra, who needs the dispensing pharmacy named, or who will not commit beyond month-to-month.
Research relevant to PlexusDx
Explore the evidence and its limits. Findings apply to the formulation, route and population studied; they do not establish the quality or effectiveness of a provider’s products.
- Sermorelin benefits: does it work? What the trials show
A real GHRH drug, read against the anti-aging pitch: an approved growth-hormone-releasing analog with a pediatric track record, and a longevity case built more on biomarkers than outcomes.
- NAD+ precursors (NR and NMN): what the human trials actually show
They raise NAD+ and look safe short-term, but human evidence is surrogate-marker level, and no trial shows they extend healthspan.
- GHK-Cu: the copper peptide between real skincare and overclaim
A decades-deep molecule with a credible topical story — and systemic anti-aging claims that outrun the human data.
- Glutathione: the master antioxidant, and where the evidence actually is
Oral glutathione really does raise your body stores (a 6-month RCT proved it) — but the longevity and detox claims are unproven, skin-lightening is modest, and IV glutathione is the most marketed, least evidenced route. The precursors may be the smarter bet.
- PT-141 (bremelanotide): the evidence on a peptide that is actually FDA-approved
Bremelanotide (Vyleesi) is FDA-approved for HSDD in premenopausal women, with phase-3 trial evidence. A straight read of what's proven — and where off-label use goes beyond it.

Frequently asked
- Is PlexusDx a genetics company or a prescriber?
- Both, but the prescribing side is real and substantial. Its hero reads "Prescription Peptide Programs for Longevity" and it runs five longevity protocols and five weight-loss protocols with published prices, reviewed by licensed clinicians from an independent network and dispensed from licensed 503A pharmacies. It also sells genetic and blood tests separately.
- Do I have to buy the genetic test?
- No. The Precision Peptide test is offered as a $99 add-on after your first month of treatment, discounted from a stated $298. Nothing about your initial prescription depends on it, which is worth knowing given how central genetics is to the site's messaging.
- What do sermorelin and NAD⁺ cost?
- Each is $179 a month month-to-month, $149 a month on a three-month commitment, or $129 a month on six months, all-inclusive and the same at every dose. The "from $129" figure on the site is the six-month rate. Glutathione is a flat $125, GHK-Cu Rx $139 and PT-141 $189.
- Does PlexusDx sell methylene blue?
- No. Its longevity menu is five protocols — NAD⁺, sermorelin, glutathione, GHK-Cu Rx and PT-141 — and methylene blue, MIC B12 and Lipo C are not on it.
- Is PlexusDx legit?
- PlexusDx is a peptide telehealth service you reach through an online questionnaire. Its stated availability: All 50 states claimed; live video required in five. What it publishes up front: Sermorelin $179/mo month-to-month, $149 on a 3-month plan, $129 on a 6-month plan, all-inclusive with provider check-ins; genetic test a separate $99 add-on. It is cash-pay and states it does not bill insurance. Before you pay, ask in writing about which medications it dispenses.
- Is PlexusDx expensive compared with other peptide telehealth providers?
- PlexusDx publishes a starting figure of $179/mo. Across the 75 peptide telehealth providers we review that publish a single monthly figure, those run $49 to $349 with a median of $189, which puts PlexusDx below the median, toward the cheaper end. The other 142 peptide telehealth providers 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.
