We're the lab,
not the layer.

Just Greys was started by researchers who got tired of paying $300 for a vial that costs $40 to make. The US peptide market runs on a brutal stack: overseas synthesis → US importer → "wellness brand" → you. Each layer adds a markup. By the time it reaches a research bench, you're paying 5x.

We cut every layer except the lab and the lab tech. We hold inventory in a US facility, ship cold-packed in under 24 hours, and price the way the gray market actually prices.

Every batch is HPLC-tested for purity (typically >99%) and mass-spec verified. Certificates of Analysis available on request. We don't sell anything we wouldn't pipette ourselves.

We are not a pharmacy. We do not sell to patients. Everything here is sold for in-vitro research and laboratory use only.
