Peptidology's terms, privacy policy and contact pages name no company: they give the trading name, 11111 North Scottsdale Rd, Suite 205, Scottsdale, AZ 85254, and Arizona governing law. The USPTO lists Nine of One LLC, an Arizona limited liability company at 11111 North Scottsdale Rd, as the applicant for the PEPTIDOLOGY trademark, filed on 31 October 2025. Arizona records hold Nine of One LLC (23754750), a domestic LLC with active status, at 11111 N Scottsdale, Suite 205, Scottsdale, with ZIP code 85258 rather than the site's 85254.

We searched the FDA's warning-letter index and openFDA drug enforcement records for the name and the domain and found no action naming Peptidology or peptidology.co. We also searched “Peptidiology” (a spelling its privacy policy uses) and “Nine of One”, with and without spaces, and found nothing naming it.

Its certificates page, open without a login, lists lab reports by product and lot. We opened the 252 lot pages it publishes: each gives a lot number and links a report PDF, with test dates from 24 February 2025 to 6 October 2026. 250 name Vanguard Laboratory of Olympia, Washington, 196 of them with Eagle Analytical Services for sterility; one names only Eagle Analytical and one Ethos Analytics. The Vanguard report we opened names Peptidology at its Scottsdale address as the client; we did not confirm any certificate with the laboratory.

peptidologyusa.com, registered 25 July 2026, runs a shop as Peptidology USA that gives only an email address. peptidologylabs.com, registered 8 August 2026, runs a shop as Peptidology Labs that gives a 2pm Central Time same-day shipping cutoff and only an email address. peptidology.us shows only an age-check page whose buttons both link to peptidology.co, and peptidology.store redirects to primepeptides.us. Neither shop links to peptidology.co, and we could not establish whether any of these sites is connected to it. The site this record covers is peptidology.co.
