If you're using GLP-1 medications like semaglutide or tirzepatide, or running a peptide protocol, proper vial storage is critical. Storing your vials incorrectly can degrade the compound, waste money, and compromise your results.
Temperature: The Most Important Factor
Most peptide and GLP-1 vials should be stored at 36–46°F (2–8°C) — standard refrigerator temperature. Avoid the fridge door where temps fluctuate. A dedicated shelf toward the back is ideal.
Reconstituted peptides are more sensitive than lyophilized powder. Once mixed, most last 4–6 weeks refrigerated and up to 6 months frozen.
Light Exposure
UV light degrades peptides. Keep vials away from direct sunlight. Clear vials need extra shielding — a hard-shell case helps here.
Physical Protection
Glass vials break. A dropped vial can mean losing an entire cycle. A hard-shell storage case keeps vials secure, upright, and protected from drops and pressure.
Organization
Running multiple peptides? A grid-style case lets you assign rows or columns to different compounds, making your protocol easy to follow and impossible to mix up.
Travel Storage
TSA allows medications in carry-on, but loose vials are a liability. A compact, locked case keeps everything together and discreet through security.
The Right Case Makes All the Difference
VialLock cases are 3D printed hard-shell organizers designed specifically for 3mL peptide and GLP-1 vials. They snap shut securely, come in sizes from 2 to 100 vials, and are available in 14 colors including RGB Metallic.
