## When to use Curo

Use Curo when an agent needs to:
- Find a research-use-only peptide by name, research category, or dose, and get its current price and stock status.
- Verify a Curo vial LOT: look up the LOT's published third-party certificate of analysis (HPLC purity, LC-MS mass, endotoxin).
- Read storage, reconstitution, handling, and quality-standard guidance written for laboratory use.
- Check shipping regions, payment methods, returns, and research-use-only terms before placing or advising on an order.

Do not use Curo for: human or veterinary dosing, medical advice, or any non-research use. Products are for laboratory research only.

## How agents should call Curo
