Lyophilized vs liquid stability Extremely stable Water removed = minimal degradation 2-3 years shelf life (refrigerated) 3-5 years (frozen) Can survive room temp short periods Liquid (reconstituted) : Much less stable Degradation begins immediately 28 days max with bacteriostatic water 1-3 days with sterile water Must stay refrigerated This is why peptides ship as powder : Stability during shipping, longer shelf life, easier storage
