WHOIS: WHOIS lists registrant org 'American Peptides LLC' and registrant name 'RON KILGARLIN' (Shreveport, LA), registered 2026-02-21, expiry 2029-02-21. Ron Kilgarlin is a documented Shreveport entrepreneur — founder/CEO of American Screening Corporation (est. 2004, diagnostic tests & medical supplies) and operator of ASC Fulfillment USA, a Shreveport-based 3PL claiming 2-day delivery to 96% of the US (which lends plausibility to the same-day-ship / 2-3-day-delivery claims). CONFLICT: the site presents an established track record — '10,000+ Researchers Served', '67% repeat order rate', '99.7% avg purity across the last 500 batches', 'zero recalls since launch', '4.9/5 from 2,400+ verified researchers' — yet the domain is only ~4 months old (registered Feb 2026), so these scale/track-record figures are not independently verifiable and appear inflated for the site's age. No explicit founding year is stated on the site. who.is

3 platforms on record — scores differ by scale; read the notes
Algorithmic 0/100 'Likely Unsafe'. Flags: Gridinsoft 'possible malware' report, ~4-month domain age, low Tranco traffic, internal-only review system. Positives: valid Let's Encrypt SSL, 3-year advance registration, on-file owner (Ron Kilgarlin / American Peptides LLC, Shreveport LA).
Vendor-stated '4.9/5 from 2,400+ Verified Researchers' rating displayed on its own site. Self-hosted/internal review system per ScamAdviser; NOT corroborated by any third-party platform and implausible in volume for a domain registered Feb 2026. Treat as a vendor claim, not independent reputation.
A similarly-named domain ('ameanopeptides.com') has ~434 Trustpilot reviews. Relationship to americanpeptides.us is UNCONFIRMED; surfaced only because the names collide. Do not attribute these reviews to American Peptides without confirmation.
No third-party reputation corroboration was found. The site advertises a '4.9/5 from 2,400+ Verified Researchers' rating, but per ScamAdviser this runs on an internal/self-hosted review system rather than any third-party platform, and no Trustpilot, Reddit, BBB or forum presence for americanpeptides.us could be located (the domain is only ~4 months old). ScamAdviser rates americanpeptides.us 0/100 ('Likely Unsafe'), citing a Gridinsoft 'possible malware' report, very young domain age, low Tranco traffic and the internal-only review system, while noting valid SSL and on-file owner details (Ron Kilgarlin, American Peptides LLC, Shreveport LA). A separate Trustpilot profile exists for 'ameanopeptides.com' (a similar-sounding name); its relationship to americanpeptides.us is unconfirmed and it is treated here as unrelated/unverified.
