LunaRx is the cheapest of the three sellers sharing this peptide template on sermorelin, MOTS-C and epithalon, and the only one of them that prices semax at all — though it prices semax only as half of a two-compound line.
By Nora Castellan, Standards EditorUpdated September 2026
Eight compounds priced, including one almost nobody prices
Semax is close to absent from published price lists: thirty-eight sellers here declare it and nine publish a figure. LunaRx is one of the nine, and its figure is a monthly one.
The catch is that the figure covers 'Semax / Selank', two nootropic peptides sold as one line. Selank is not tracked here, so the figure is recorded under semax with that limitation stated rather than presented as a clean semax price.
The rest of the menu — sermorelin, tesamorelin, MOTS-C, GHK-Cu, epithalon, BPC-157 and NAD+ — is priced per month per compound, all on one page.
It says 503A on its own homepage
The homepage reads '503A compounded — no reconstitution required'. Naming the regulatory class is more information than most sellers here give, and the reconstitution point is a practical one: a patient who does not have to mix a vial makes fewer errors.
LunaRx LLC is named on the site itself rather than only in a terms page a reader has to hunt for.
The clinical framing is unusually specific too: the site describes GLP-1 therapy paired with muscle-protective peptides and a structured off-ramp, in English and Spanish.
Same template, different company, lower prices
This peptide page is structurally identical to two other sellers reviewed here. The headings, the categories and the descriptive sentences match line for line.
LunaRx sets lower numbers than either sibling on several compounds. That is the seller's decision and it is real; it is simply not evidence of an independently built catalogue.
It inherits the template's misfiled descriptions as well, including a copper-peptide sentence sitting under a blend that contains three other things.
The gaps
No list of served states is published. A reader in a restrictive state finds out at intake.
No dispensing pharmacy is named, and no certificate of analysis is reachable for any compound on the menu.
The federal warning-letter record contains nothing for this company or brand, checked against the live table rather than a stored snapshot.
Who it's for
Readers looking for a published semax figure rather than a quote.
Shoppers who want the lowest sermorelin, MOTS-C or epithalon on this template.
Buyers who value a stated 503A supply chain and a named company.
Spanish-speaking readers, since the seller says it works in both languages.
Who should look elsewhere
Anyone who needs semax priced on its own rather than beside selank.
Readers who want a named pharmacy or a certificate of analysis.
Buyers who need a state list before starting an intake.
Shoppers who want a catalogue that is not shared with two competitors.
Strengths
Prices eight compounds per month, including semax, which few sellers here price at all
Says on its own homepage that its protocols are "503A compounded — no reconstitution required"
Names LunaRx LLC on the site itself, not only in a buried terms page
Undercuts both of its template siblings on sermorelin, MOTS-C and epitalon
Trade-offs
Its peptide menu is identical to two other sellers here, under a different company
Prices semax only as a two-compound "Semax / Selank" line
Publishes no state list and names no dispensing pharmacy
No certificate of analysis is reachable anywhere on the site
How we verified this
Read the peptide menu and recorded each compound-scoped monthly figure with the period the page states.
Recorded the semax figure as a two-compound line rather than as a clean semax price.
Compared the page against two sibling sites and recorded the shared template.
Read the site and its terms for the operating company and recorded LunaRx LLC.
Screened company and brand against the live federal warning-letter table, filtering locally because the table's own search parameter is ignored.
A provider to compare LunaRx 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.
Not exactly. The line reads 'Semax / Selank' and one figure covers both. It is recorded under semax because semax is the tracked half and the seller names it first, with the pairing stated.
What does '503A compounded' mean here?
It is the seller's own description of the pharmacy class that prepares its medication. It tells you the regulatory category; it does not tell you which pharmacy, and LunaRx does not say.
Is LunaRx cheaper than the other two sellers on this template?
On sermorelin, MOTS-C and epithalon, yes. On the compounds the three share it is generally the lowest of the set, though not on every line.
Does it publish test results?
No. Nothing resembling a certificate of analysis is reachable anywhere on the site.
