Did Eternal Peptides Shut Down? The September 2026 Notice

Eternal Peptides stopped selling in September 2026: eternalpeptides.com now serves a single page reading "Thank you for supporting us at Eternal Peptides. Customer support will be available until September 30th." Per The Peptide Catalog, vendor trackers date the wind-down to around September 15, 2026, and the company has published no reason for the closure.

Did Eternal Peptides shut down?

Yes, per the notice on its own domain. An Internet Archive capture dated September 20, 2026 shows eternalpeptides.com serving the thank-you notice in place of a catalog, and the domain served the same notice when we read it on October 19, 2026. The Peptide Catalog, a vendor-comparison site that earns affiliate commissions from other sellers, reported on September 22, 2026 that vendor trackers date the wind-down to around September 15, 2026.

Why did Eternal Peptides close?

The company has not said. The notice gives no reason, and we located no enforcement action, lawsuit, or company statement tied to the closure as of October 19, 2026. The Peptide Catalog likewise reported that no official reason was published.

What happened to orders placed before the closure?

The notice gives one date: customer support "will be available until September 30th," with a support email listed. That date has passed. The notice does not mention refunds, store credit, or unshipped orders. Per The Peptide Catalog's September 22, 2026 report, the lab-test archive at eternalpeptides.com/lab-tests/ still loaded after the storefront was removed. Facts only, no legal advice: standard card-network dispute processes exist independently of any vendor, with eligibility windows and timelines set by the card issuer.

Are there impersonator sites using the Eternal Peptides name?

The Eternal Peptides notice does not address successor or impersonator sites, and we located no company statement on the subject as of October 19, 2026. Other 2026 closure notices did carry such warnings: Chemyo, Peptide Sciences, and Science.bio each state that parties claiming to be them or their successors are unauthorized.
