  "description": "A2A Peptides is the cleared-commerce hub for the peptide industry, operated by GreenCore Solutions Corp. (GSC). It is a jurisdiction-and-pathway gate that only exposes items cleared to transact, with a catalogue behind it that only holds what passed. Every answer comes from a register page, carries its source and its rule-set version, and is signed. Agents reach it over the Model Context Protocol (MCP) and Agent-to-Agent (A2A); settlement is x402 after the gate. Research-use stock is a reject class the door names and refuses. No research and development happens here.",
