The Dead Space In Your Peptide Pen That Wastes Real Product
Machine-readable facts for this Lab article. The full page is https://www.preppinpeppers.com/blogs/the-lab/the-dead-space-in-peptide-pen-wastes-real-product.
TL;DR
Dead space in the pen tip and needle hub holds fluid that never dispenses. A pen meters volume by click-dial only, so reconstitution accuracy is your own math.

FAQ
- Is a metal peptide pen better than a plastic one?
- For repeated use, yes. Metal dial mechanisms hold calibration longer than molded plastic ones, which can develop play and under-deliver slightly after heavy use.
- What is dead volume in a peptide pen needle?
- It's the small amount of liquid trapped in the needle hub and cartridge neck that never reaches the tip. It matters most when you're metering very small click volumes.
- Can you freeze a loaded peptide cartridge for storage?
- No. Water expands as it freezes and can crack the glass or dislodge the seal, ruining the cartridge. Refrigerate instead, never freeze.
