Modern Age sells its peptides by the session and by the injection in a physical clinic, states both units explicitly, and publishes no corporate name anywhere in its terms except its payment processor's.
What Modern Age charges
NAD+: $750 — PER SESSION, not per month: printed as "IV Drip Therapy: NAD+ — $750/session — NAD+ IV in our NYC Clinic — Approximately 3 hours", with an option table beneath it beginning "1 session $750". An in-person infusion in a named city, not a shipped subscription
Glutathione: $50 — PER INJECTION, not per month: printed as "Glutathione Injection: Stress — $50/injection", with "Visit us in our NYC Clinic — Book an appointment or walk in any time" beneath it. The lowest figure on this roster and the smallest unit

A unit stated, and it is not a month
The infusion page prints its figure with the words per session attached, says how long a session takes, and follows it with an option table listing single and multiple sessions at their own figures. The injection page does the same with the words per injection.
Being explicit about a unit that is not a month is more useful than being vague about one that is. A reader knows immediately that these figures are not comparable to a shipped subscription without doing arithmetic the seller has not enabled.
Both are recorded as figures that are not monthly rates, with the unit written into the qualifier.
The gap between an in-clinic infusion here and a shipped monthly injection elsewhere on this roster is the largest single-compound spread on the site, and the units are the reason.
Three business models, one compound name
The coenzyme on this roster is sold as a monthly shipped subscription by most sellers, as a per-vial purchase by a few, and here as a three-hour infusion in a named city.
Those are not three prices for one thing. They are three different services that happen to involve the same molecule, delivered in different volumes by different routes with different amounts of clinical supervision.
A comparison table that ranks them against each other on price alone would put this seller last by a wide margin and would be measuring nothing.
This site keeps the unit on the row and the model in the review, so the figure is visible and the comparison is not silently made.
The only corporate name is a payment processor's
A census of the terms and conditions found one corporate name in the whole document. It belongs to the payment processor, introduced in a sentence about third-party payment vendors.
No operating company, no professional corporation, no medical group. A reader who wants to know which company they would be contracting with cannot find out from the terms.
This is the same failure shape as a website vendor's name or a telehealth platform's name standing in for an operator — three examples of which appear in this batch — and it is the reason a corporate-name pattern match has to be read in its sentence before it is recorded.
Screened by brand and by the payment processor's name against the regulator's warning-letter index, no letter names this seller.
What a clinic can tell you that a website cannot
The pages state where the service happens, that walk-ins are accepted, that a consultation is available, and how long the infusion takes. None of that exists on a shipped-subscription seller, and all of it matters to a buyer choosing between the two models.
The infusion page also prices a concierge home session as a separate option, which is a third delivery model again.
The catalogue is narrow — a coenzyme and an antioxidant — and the site also sells third-party supplements, which are not peptides and are not recorded here.
No dispensing pharmacy is named, no certificate of analysis exists on the pages read, and no state coverage list is published, which for a single-city clinic is less surprising than it is elsewhere.
Who it's for
Readers comparing an in-clinic infusion against a shipped subscription who need the two units kept apart.
Buyers who want to know how long a treatment takes before booking it.
Anyone who wants multi-session pricing published rather than quoted on request.
Shoppers near the clinic who would rather walk in than complete an intake.
Who should look elsewhere
Anyone outside the city where the clinic operates.
Readers who want a monthly figure, since nothing here is priced by the month.
Buyers who want to know which company they are contracting with, which the terms do not say.
Shoppers who want a certificate of analysis or a named dispensing pharmacy.
Strengths
States its unit explicitly on every figure — per session, per injection — instead of leaving a period to be assumed
Prints how long the infusion takes beside the price, which no shipped-subscription seller can offer
Publishes an option table with multi-session pricing rather than one headline figure
Says where the service happens and that walk-ins are accepted
Trade-offs
The only corporate name in its terms is its payment processor's
A single physical clinic, so its figures are not comparable to a nationwide shipped programme
No dispensing pharmacy named and no certificate of analysis
Its per-session figure is many times any subscription figure on this roster, and the units are not interchangeable
How we verified this
Loaded both treatment pages and the terms with a full browser user-agent, printing the effective URL beside the requested one on each.
Ran a nonsense-path control on the host in the same run, which returned a not-found status.
Joined the page's text nodes before matching any figure, so a price split across elements could not read as an absence.
Recorded the seller's own unit on each figure — per session and per injection — rather than converting either into a month.
Read the option tables beneath each figure and recorded the single-unit price rather than a package rate.
Ran a census of the terms document for corporate names and recorded that the only one present belongs to the payment processor, read in its own sentence.
Declined to record an operating company on that basis.
Screened the brand and the payment processor's name against the regulator's warning-letter index, with a nonsense query as a control in the same run.
A provider to compare Modern Age 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.
