Here's a practical shelf life guide for the most common compounds — and how proper storage extends those numbers.
Lyophilized Peptide Shelf Life
BPC-157: room temp 3-6 months, refrigerated 12-18 months, frozen 2+ years. TB-500: same. Semaglutide: room temp 1-3 months, refrigerated 6-12 months. Tirzepatide: same as semaglutide. Retatrutide: room temp 1-3 months, refrigerated 6-12 months. CJC-1295: room temp 3-6 months, refrigerated 12+ months. GHK-Cu: room temp 1-3 months, refrigerated 6-12 months.
Reconstituted Peptide Shelf Life
Once reconstituted with bacteriostatic water, most peptides are good for 28-30 days refrigerated. Bacteriostatic water (with 0.9% benzyl alcohol) extends this compared to sterile water.
How Storage Conditions Affect Shelf Life
Heat, light, and physical agitation all degrade peptides faster. A VialLock hard-shell case protects against light exposure and physical damage. Shop VialLock cases.
