Our peptides are shipped as a lyophilized (freeze-dried) powder because they are highly unstable in liquid form. Lyophilization removes almost all the water, preserving the peptide’s delicate structure and greatly extending its shelf life during transit.
To use a lyophilized peptide, it must be dissolved (reconstituted) using a sterile liquid, such as bacteriostatic water or saline, depending on the specific application.
