These are allegations, and no court has ruled on them. Docket: https://www.courtlistener.com/docket/74935394/eli-lilly-and-company-v-brown/

Strate LabsRedirects to another storeOct 20, 2026When we checked on October 20, 2026, stratelabs.is redirected to glpeptides.is, a store trading as GL Peptides. We have not confirmed whether GL Peptides is the same business as Strate Labs, so this listing does not link to it.
QSC PeptidesWebsite offlineOct 18, 2026qscpeptide.com is not reachable. The domain registrar has placed it on hold (status "clientHold"), which stops the site from loading. Registrars usually do this after abuse or compliance complaints, or a billing problem. QSC has not announced a new address. qscpeptides.com (with an "s") is a separate placeholder page with no shop, so treat any site claiming to be QSC with caution. Related suppliers are listed further down this page.

Paused or in maintenance

The site is up but shows a maintenance or not-taking-orders page instead of the store.

Not responding to our checks

Failed our automated check 2 weeks in a row. Not yet reviewed by us: a site can fail for scripts and still load in a browser, so treat this as a warning, not a closure.

How we check

Every week a script requests the homepage of each listed supplier. A site that answers counts as responding, including sites that block automated requests (common behind Cloudflare), since they still load for people. A site counts as not responding only after 2 failed weekly checks in a row. We review those by hand, and only then mark a listing offline, with a dated notice on its page.

Know of a supplier that closed or moved? Email hello@peptidesuppliers.tech and we will re-check the listing.
