PlexusDx puts a published figure on five of the six compounds this site ranks, which only five other sellers here manage. Three of those five are a single flat monthly rate; the other two are a three-tier ladder whose advertised headline figure is its longest commitment.
What PlexusDx charges
PT-141: $189/mo — per month flat, in the seller's words "no commitment tiers, no per-dose surcharge" — one charge covering "your provider visit, prescription, medication, and shipping"
GHK-Cu: $139/mo — per month flat, in the seller's words "no commitment tiers, no per-formulation surcharge" — a cream, not an injection
Glutathione: $125/mo — per month flat, in the seller's words "no commitment tiers, no per-formulation surcharge" — but the same page says both "Eligible adults in 46 states" and "Available in all 50 states"
Sermorelin: $179/mo — per month on the seller's own "Month-to-month" tier — the shortest of three, beside "3-month $149 /mo" and "Best value 6-month $129 /mo"
Sermorelin: $129/mo — per month on the seller's "Best value 6-month" tier — the figure its own page headline advertises as "from $129/mo"
NAD+: $179/mo — per month on the seller's own "Month-to-month" tier — the shortest of three, beside "3-month $149 /mo" and "Best value 6-month $129 /mo"
NAD+: $129/mo — per month on the seller's "Best value 6-month" tier — the figure its own page headline advertises as "from $129/mo"

Five boards, and two different shapes of price
Sermorelin, NAD+, glutathione, GHK-Cu and PT-141 each have their own program page here, so this seller reaches five of the six compounds this site ranks. Seven of the thirty-one sellers compared here reach five or more, and only six of the thirty reach the PT-141 board at all.
PT-141, GHK-Cu and glutathione are priced as one flat monthly rate. The pages say so in the same words each time — no commitment tiers, and no surcharge for the formulation or the dose the provider settles on.
Sermorelin and NAD+ are priced differently, on three named tiers: month to month, three months, and a six-month tier the page labels best value. The two figures this site records for each of them are the ends of that ladder, because they are not the same offer. A reader who wants to stop after one month pays the top of the range, and the figure the page headline advertises is the bottom.
Both program pages make the same promise about titration: the monthly charge does not move when the dose does. That is a real distinction from sellers whose price climbs with strength, and it holds across all five programs.
The glutathione page contradicts itself about who can buy
Its own summary paragraph says the program is for eligible adults in forty-six states. Two sections further down the same page, the copy says the program is available in all fifty states, and the shipping line promises free discreet shipping in all fifty.
The page then names the exclusions that would produce the smaller number: one formulation is described as unavailable in Arkansas, and the other as unavailable in Arkansas, Indiana, Minnesota and South Carolina. Four states, and a forty-six-state footprint, sit on the same page as the fifty-state one.
Neither statement is buried and neither is a footnote. This site records the conflict rather than picking the reading that flatters the seller, because the seller has not picked one either.
The other four programs say all fifty states without qualification. Twelve of the thirty-one sellers here claim a fifty-state footprint; sixteen publish a state list of any kind.
The company gives its own name two ways
One terms document on this domain opens by naming the operator as PlexusDx, Inc. and repeats that form throughout, and it puts the governing law in Delaware. A second terms document, at a different address on the same site, defines the same brand as PlexusDX LLC and its affiliates.
An incorporated company and a limited liability company are different legal entities with different owners and different liability. A shopper trying to look up who they are contracting with will find two answers on one website.
This site records the corporation form from the policies document, because that is the page the checkout flow links, and names the disagreement here so a later reader does not quietly correct one into the other.
What the monthly charge covers, and what sits outside it
Every program page itemizes the same four things inside the price: the provider review, the prescription, the compounded medication, and shipping. The pages state there is no membership fee and no separate consult charge.
The pharmacies are described as state-licensed compounding pharmacies operating in FDA-registered facilities, and are never named. Eight of the thirty-one sellers here name the facility that fills an order, which is what makes it possible to look one up.
Bloodwork is not in the price. This seller does sell blood panels and genetic reports, but as separate products, and its peptide genetics test is described as an add-on available after the first month of treatment rather than part of the program.
The pages also say five states require a scheduled video visit rather than the asynchronous intake, and then never say which five. That is a fact a reader in one of those states would want before starting.
None of these five compounds is an FDA-approved finished drug. The site's own disclosure says as much: compounded medications have not been evaluated by the FDA for safety, efficacy or quality.
Who it's for
Readers assembling more than one ranked compound who would rather do it from a single seller than from three.
Anyone who wants the commitment tiers listed side by side instead of only the cheapest one advertised.
Buyers who would prefer a topical cream or a nasal spray to an injection, since two of these five programs are supplied that way.
Shoppers who want the provider visit, the prescription and shipping named inside one charge rather than itemized later.
Who should look elsewhere
Anyone who needs a settled answer on state coverage, since the glutathione page publishes two different footprints.
Readers who want the compounding pharmacy named rather than described as a category of facility.
Buyers who expect bloodwork inside the price, since panels and genetic reports are sold separately here.
Anyone who needs to know before signing up whether their state is one of the five that require a scheduled video visit.
Shoppers who want a single unambiguous corporate counterparty, given the two entity forms published on this domain.
Strengths
Reaches five of the six compounds this site ranks, one of seven sellers here to reach five or more
States on every program page that the monthly price does not change as the dose changes
Names the three commitment tiers and their per-month rates side by side instead of advertising only the cheapest
Offers GHK-Cu as a topical cream and glutathione as a nasal spray or troche, so two of the five need no injection
Trade-offs
Publishes its own corporate name two different ways — "PlexusDx, Inc." in one terms document and "PlexusDX LLC" in the other
The glutathione page states both a 46-state and an all-50-state footprint without resolving which applies
No compounding pharmacy is named on any of the five product pages
Five states are said to require a scheduled video visit rather than the async intake, but the page never lists which five
How we verified this
Loaded each of the five program pages twice, more than a minute apart, and compared the price, term and state wording token by token; all five were identical across the pair.
Probed the host with a nonsense product path in the same run and confirmed it returns a not-found response, so a success on these pages means a page rather than a catch-all.
Checked the final resolved address of every fetch, because a product path that answers successfully while landing on a homepage is not a product page.
Recorded both ends of the sermorelin and NAD+ tier ladders rather than the advertised headline alone, since the headline is the longest commitment.
Read both terms documents on the domain and recorded the two different corporate forms as published, without reconciling them.
Recorded the glutathione page's forty-six-state and fifty-state statements side by side, along with the named formulation exclusions that produce the smaller figure.
Searched all five program pages for a named pharmacy and found only category descriptions.
A provider to compare PlexusDx against
Trellis Vitality
Trellis Vitality frames its program around body-composition tracking rather than scale weight, pairing NAD+, glutathione and tesamorelin with at-home biomarker panels and a 90-day re-test, and names its dispensing pharmacy, VialsRX in Houston, by address.
Is the advertised sermorelin price the price of one month?
No. The figure the page headline advertises is the six-month tier, which the page itself labels best value. A buyer who wants month-to-month billing pays the top of the three-tier ladder, and both ends are recorded here.
Does the monthly price go up as the dose goes up?
The seller says it does not. Every program page states that the charge stays the same as the dose changes, and that there is no surcharge for the formulation a provider selects.
Can I buy the glutathione program in my state?
The page does not settle it. The same page says both forty-six states and all fifty, and separately names Arkansas, Indiana, Minnesota and South Carolina as places one or both formulations are unavailable. Ask before paying.
Which pharmacy fills the prescription?
It is not named. The pages describe state-licensed compounding pharmacies operating in FDA-registered facilities, which is a statement about a category rather than an identifiable facility.
Are labs included in the monthly charge?
No. The charge covers the provider review, the prescription, the medication and shipping. Blood panels and the genetic report are separate products, and the peptide genetics test is offered as an add-on after the first month.
Who am I actually contracting with?
The site publishes two answers. One terms document names an incorporated company; another names a limited liability company. This site records the corporation form and flags the disagreement rather than choosing between them.
