Eternal Peptides closed. Here's how to choose a new research supplier.

Eternal Peptides stopped taking orders on 15 September 2026, after announcing the closure on its website. Before you order from anyone new, confirm that the supplier publishes a lab report for the exact lot it will ship, that the testing laboratory can verify that report, and that you know where the parcel ships from and who answers support.

Five questions before your first order

When a supplier you relied on closes, the next one is usually a site you have never ordered from. You can answer each of these questions from the supplier's own website, before you pay, in a few minutes. Ask them of every supplier on your shortlist, us included.

  1. Is there a third-party report for the lot I will receive?A report covers one sample from one production lot, so a useful one names its lot. When your parcel arrives, the lot on the vial label should be the lot on the report.Red flag: the same report attached to several products or strengths, or no lot number anywhere.
  2. Can the laboratory confirm the report?The report should name the lab that ran it and give a certificate number or verification link that works on the lab's own site. Then you are relying on the lab, not the seller.Red flag: no lab named, or a certificate number the lab cannot find.
  3. Can I read it before I pay?The report should be one click from the product page, with no account and no email request.Red flag: "available on request," or a report sent only after checkout.
  4. Where does it ship from, and when do I get tracking?A supplier should state its shipping origin and send tracking when the label is created.Red flag: no origin stated anywhere, and tracking only if you ask.
  5. Who do I contact if something is wrong?Look for a registered company name, a support email with stated hours, published return terms, and research-use-only terms throughout the site.Red flag: only a contact form, or product pages that make health claims or give use instructions.

Where we fall short today. Current lot-matched reports cover the products listed in our report library, not the entire catalog. A product without a current report says so on its page. We would rather show the gap than hide it.

Keep your old records

If you saved order confirmations or copies of lab reports from past orders, keep them. They are a useful baseline for comparing a new supplier's documentation.
