How to Label Your Peptide Vials — Organization System for Multi-Compound Users

Organized VialLock vial case setup

Managing multiple peptide compounds means one thing above all else: never confuse your vials. Here's a simple, reliable labeling and organization system that takes five minutes to set up and prevents costly mistakes.

The Basics: What to Write on Every Vial

  • Compound name — abbreviated is fine (SEM for semaglutide, BPC for BPC-157)
  • Concentration — mg/mL after reconstitution
  • Date reconstituted — discard after 30 days
  • Volume remaining — update after each draw (optional but helpful)

Best Labeling Materials

Masking tape and a fine-tip permanent marker work perfectly on glass vials. Wrap a small strip around the vial body. Avoid labels on the cap — they fall off. Color-coded tape by compound type is an easy upgrade.

How VialLock Cases Help

VialLock's snug-fit grid slots keep vials in fixed positions — assign each slot to a specific compound and they'll always be in the same place. No more hunting through a bag for the right vial.
