These names appear on other vendor lists but their sites did not load, redirect elsewhere, or publish nothing we could check. Listed so readers know we looked.
- American Research Labs — unknown: Could not locate an operating website. The two candidate domains (americanresearchlabs.com, americanresearch.net) both redirect away to unrelated pages, and the only vendor descriptions come from an affiliate listing (Outliyr, 1.8/5) and Trustpilot regional pages for americanresearch.net that mention third-party lab reports. Treat as unverified/possibly defunct; all catalog, pricing and testing fields are unknown. Not to be confused with American Peptide Company (americanpeptide.com, an Otsuka subsidiary).
- Apex Peptides — apexpeptides.com: Could not be verified: apexpeptides.com served a maintenance page and apexpeptides.org (the domain listed by Peptide Protocol Wiki, last verified 2026-02-19) returned 403. The wiki describes a US-only, card-only vendor with 7 listed peptides and HPLC COAs from unnamed 'accredited US laboratories'; the product list above is the wiki's, not the vendor's. Multiple unrelated 'Apex Peptides' domains exist in other countries, and the one Trustpilot profile found (apexpepts.com) has been removed. Status left unknown.
- Arctic Peptides — arcticpeptides.com: Homepage, product pages and products.json all return a Cloudflare 403 block; the domain still resolves (Cloudflare IPs) so the site appears to exist, but current trading status could not be confirmed. Everything here comes from the unclaimed Trustpilot profile (2.6/5, 10 reviews, last Oct 2024) and one third-party review article (millennialhawk.com), which says the vendor claims 99%+ purity verified by two independent labs and sells BPC-157, TB-500, Ipamorelin, CJC-1295 No DAC, semaglutide and retatrutide. No FDA warning letter naming Arctic Peptides was found in search. Not the same business as Arctic Labs (arcticlabs.co) or Arctic Lab Supply (arcticlabsupply.com).
- Canada Peptide — canadapeptide.com: No vendor site named exactly 'Canada Peptides' was found; canadapeptides.com returned HTTP 523 twice and canadapeptide.com (Canada Peptide, the vendor named in the Health Canada advisory) returned HTTP 403, so all vendor-side fields are unverified and fetched_ok is false. The only official record is Health Canada's 2025-08-01 public advisory on unauthorized injectable peptides seized from and sold by Canada Peptide; the advisory does not name the domain, but CP24's report links it to canadapeptide.com. A 2018 Podbean page describes Canada Peptide as a division of a Montreal biotech company; peptideprotocolwiki reports Canada-only shipping, credit-card payment, free shipping over $400 CAD and in-house HPLC/MS reports; none of this was verifiable on the vendor site so it is kept out of the structured fields. Formats set to vials only because Health Canada describes the products as injectable.
- Narrows Labs — narrowslabs.com: The domain narrowslabs.com (WHOIS: registered 2017-03-29 via GoDaddy, status clientDeleteProhibited/clientRenewProhibited, updated 2026-08-15) currently serves only a redirect stub to router.parklogic.com, a domain-parking service, and the www host fails TLS. No vendor pages, COAs, pricing or contact details could be read, and no Trustpilot, Reddit, Finnrick or FDA records naming Narrows Labs were found before the search budget ran out. The brand appears inactive or parked as of 2026-10-19; status left as unknown because closure was not confirmed by any source.
