Vendor archive — retired research-peptide suppliers
Vendors we've stopped tracking and why. Most peptide-pricing sites quietly drop retired vendors so users can't tell whether a supplier went out of business, was compliance-flagged, or got reports of bad COAs. We publish the reason so anyone Googling a former vendor name lands here instead of on a stale review.
How vendors end up here
- • Vendor goes out of business or stops fulfilling orders
- • Pattern of failed COAs or low-purity batches reported by multiple readers
- • Compliance / regulatory enforcement against the vendor
- • Vendor refuses to provide a COA on request after a confirmed bad batch
- • Editorial decision after multiple unresolved customer-service complaints
Archive entries stay live indefinitely. If you're researching an old vendor name and you ended up here, that's the point — we'd rather you know exactly what happened than think we just stopped reviewing them.
