What Happened to Peptide Sciences?

What the shutdown exposed

When a supplier disappears, a buyer loses more than a storefront. They lose access to the provenance records, batch context, and customer-service relationship that were supposed to support a purchasing decision. The lesson is not panic. It is to separate a brand claim from independently verifiable evidence.

This page tracks the questions that matter after a disruption: what was publicly communicated, what documentation can still be independently checked, and what a buyer should verify before relying on any replacement source.

What a real certificate of analysis requires

A useful certificate of analysis is more than a vendor-issued PDF. It should identify the batch, the testing method, the laboratory, and a way to verify the result independently with the laboratory itself. A buyer should be able to trace a claim without asking the seller to interpret the evidence.

Testing documentation is one signal, not a medical endorsement or a guarantee of suitability. Consult a licensed clinician for decisions about prescription medicines or health conditions.

The durable rule

Trust needs a chain of evidence. The seller can explain a product. The independent laboratory can verify a result. The buyer should be able to see where those two stories meet and where they do not.
