## FAQ

### What is gansulin used for in research?

Gansulin is an insulin formulation used in laboratory research studying glucose metabolism, insulin signaling, or diabetes models.

### Should I use an insulin pen or vial for research?

Vials give you full control over reconstitution and concentration; pens are convenient but limit your ability to verify actual dosing.

### How do I store reconstituted insulin for experiments?

Keep at 2-8°C, avoid freeze-thaw cycles by aliquoting, and use within the stability window specified by your supplier.
