ARSYNL Rx Review

ARSYNL Rx prints a figure on every peptide it sells and a billing period on none of them, so not one of its numbers can be lined up against a monthly bill.

What ARSYNL Rx charges

Sermorelin: $249 — printed as a bare figure beside 'Provided by ARSYNL Rx'; the page states no billing period, no vial count and no supply length
NAD+: $249 — the injection listing's bare figure; no period stated. Its NAD+ nasal spray is listed separately at a different figure on the same page
Glutathione: $199 — read from the related-products strip on its own NAD+ listing, where the glutathione injection is priced; no period stated

A figure on every listing, a period on none

Each product page follows the same pattern. It gives the compound name, a line saying the product is provided by ARSYNL Rx, and then a bare figure with nothing qualifying it.

No page states a billing period. None states a vial count, and none says how long a supply lasts. Four peptide figures are published this way.

Every row here is therefore recorded as not monthly. A figure with no unit cannot be divided into a month, and inventing one would attribute a rate the seller never stated.

What the site does name

Arsynl LLC is named as the operating company on the seller's own pages. A reader can look the company up, which several sellers on this roster do not allow.

Each compound keeps its own listing rather than being folded into a plan grid. Sermorelin, NAD+ and glutathione are presented as separate items with separate figures.

The site also splits NAD+ by route. The injection and the nasal spray are listed at different figures rather than sold as a single product.

One listed product is no longer served

The glutathione nasal spray listing no longer opens, while the catalog still links to it. The injection listing loads normally and is the one recorded here.

A dead listing behind a live link is a housekeeping problem rather than a pricing one. It still means a reader can click through to a product the site will not sell them.

Glutathione's figure appears in the related-products strip on the NAD+ listing rather than on a page of its own. No period is stated there either.

The disclosures that are missing

The site publishes no list of the states it serves, so a reader cannot confirm their own before starting intake.

It does not name the pharmacy that dispenses, and nothing on its pages describes lab work as part of what the figures cover.

The published figures are the only thing here a reader can act on before contact, and they arrive without a unit attached to them.

Who it's for

Readers who want a number attached to each compound rather than a quote request.
Buyers who are willing to settle the billing period during intake.
Anyone who wants the operating company named on the seller's own pages.
Shoppers comparing injectable and nasal NAD+ as two separate products.

Who should look elsewhere

Anyone who needs a monthly rate they can compare against another seller.
Readers who want a supply length or a vial count stated beside a figure.
Buyers who need the dispensing pharmacy named.
Shoppers who need coverage in their own state confirmed before starting.

Strengths

Names its operating company on its own pages rather than leaving a reader to guess
Publishes a figure on the product page for each peptide it sells
Keeps each compound on its own listing instead of burying prices in a plan grid
Prices its nasal and injectable NAD+ separately rather than as one product

Trade-offs

Attaches no billing period to any peptide figure, so none of them can be compared
States no supply length or vial count beside a price
One listed peptide product returns a gone status while the catalog still links it
Publishes no state list and names no dispensing pharmacy

How we verified this

Read each peptide listing in full and recorded the figure together with every word printed around it.
Looked for a billing period, a vial count and a supply length beside every figure, and recorded that no listing states any of the three.
Kept the NAD+ injection and the NAD+ nasal spray as separate listings at separate figures rather than merging them into one row.
Took the glutathione figure from the related-products strip on the NAD+ listing, where the site prices it, and recorded that its nasal spray listing no longer opens.
Read the site's own pages for the operating company name, and checked whether any page publishes a state list or names a dispensing pharmacy.

A provider to compare ARSYNL Rx 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.

Frequently asked questions

Is the published figure a monthly price?

The site never says. Each listing prints a bare figure with no billing period, no vial count and no supply length, so nothing on the page turns it into a monthly rate.

Which company is behind the brand?

Arsynl LLC, named on the seller's own pages. That is a real disclosure, and a reader can look the company up rather than guess at it.

Why are the NAD+ injection and nasal spray priced separately?

The site lists them as two products at two figures on the same page. Neither carries a period, so the gap between them is a gap between two unqualified numbers.

Can I buy everything it lists?

Not the glutathione nasal spray. That listing no longer opens, although the catalog still links to it. The glutathione injection is the reachable one.
