Who's Behind Zerilyx
Quiet Supplier,
Loud Paperwork
We started Zerilyx because we were tired of suppliers that talked about purity and never showed receipts. Every compound we sell ships with a signed third-party assay — no marketing claims, just the chromatogram.
Who We Are
A Tight Catalog,
Done Properly
Zerilyx is a small US team supplying research-use peptides. We deliberately keep the catalog narrow — fewer SKUs means tighter QC, faster traceability, and a real human who knows every lot on the shelf.
The people behind the operation come from analytical chemistry and lab supply backgrounds. We've watched too many shipments arrive without paperwork — that's the gap we're closing.
