Why each click on your peptide pen is a precision lock
Machine-readable facts for this Lab article. The full page is https://www.preppinpeppers.com/blogs/the-lab/why-each-click-on-your-peptide-pen-is-a-precision-lock.
TL;DR
Each click locks the dial into a spring-loaded detent that stops the drive rod at one fixed travel distance, so every click moves the piston the same amount.

FAQ
- What does a detent do in a metering pen?
- A detent is a spring-loaded ball that snaps into machined notches on the dial, locking it at defined positions so the dial cannot stop between dose settings, keeping each dispensed volume precise and repeatable.
- How do I calculate what volume each click on my peptide pen delivers?
- Check the pen's product documentation for its per-click volume. Multiply that figure by the number of clicks dialed and divide by your cartridge concentration to find the amount of reconstituted peptide in each dispensed volume.
- Can I dial backward on a metering pen to correct a dose I set too high?
- It depends on the pen design. Some mechanisms allow backward dialing safely; others can skip detents or lose position accuracy if reversed. Always consult your specific pen's manual before dialing in the opposite direction.
