## FAQ

### What gauge needle is best for peptide pen research use?

30-gauge for drawing through vial septums, 31-gauge for repeated cartridge piercing, 32-gauge for minimal-disturbance delivery. Rotate needles to avoid septum damage.

### How do I reduce dead volume in my peptide pen?

Pre-prime the needle by dispensing 0.1ml before your actual dose. Use short-hub needles and measure your specific pen's dead volume to calculate real delivered doses.

### Does pen body material matter for peptide research?

Metal pens last longer, resist cracking, and maintain click-dial precision. Plastic pens work for low-volume use but have molded threading that can strip over time.
