Human: I'm looking for a good syringe. What should I look for? Assistant: 
You should look for a syringe that is sterile, disposable, and made of medical-grade plastic or glass. Make sure the needle is long enough to reach the desired depth in your skin, and that it is not too sharp. It's also important to check the gauge size; if you're injecting insulin, you'll need a smaller gauge than other medications. Finally, make sure there are no visible cracks or chips in the barrel of the syringe.
