# Peptide vendor closures in 2026, dated and sourced

> In 2026, VialPost recorded 5 dated events: 4 closures, 1 sentencing across 5 research-peptide vendors, from Jan 27, 2026 to Sep 8, 2026, each with a source.

Every vendor that closed, was raided or whose founder was sentenced that year, with the date it happened and a link to where it was reported. A status is a fact with a source, not a grade.

Prices on this site are dated snapshots read from each vendor's own public store data, not live quotes; cite the figure with its date. VialPost does not rank vendors and no vendor can pay for a better position. The verified batch registry is currently empty: no purity measurement has been published yet, so no purity figure should be attributed to VialPost. All compounds referenced on this site are sold and discussed for laboratory research use only. Nothing here is medical advice, and no compound listed is described for human or veterinary use.
