Lyophilised (freeze-dried) peptides are produced through a process that removes water under controlled temperature and vacuum conditions, leaving a dry and porous peptide structure often referred to as a lyophilised cake. Although this material may appear as a single solid piece when first produced, it is naturally very fragile. During normal handling and transport, vibrations and movement can cause the lyophilised cake to crack, collapse, or separate into smaller fragments inside the vial. This is a common characteristic of freeze-dried materials and does not indicate degradation or a loss of chemical integrity. As long as the vial remains sealed, intact, and free from contamination, the physical appearance of the lyophilised powder does not affect the peptide's purity or its suitability for laboratory research use. Once reconstituted using appropriate laboratory procedures, the compound should dissolve normally. If a vial arrives damaged, unsealed, or appears compromised, please contact our support team with your order and batch information so we can assist further.
