Nearly every research peptide arrives as a lyophilized powder. Lyophilization — freeze-drying — is the process that makes that possible, and it's a big part of why peptides can be shipped and stored at all.
How it works
The peptide is frozen, then placed under vacuum so the frozen water sublimates (goes directly from solid to vapor) without passing through a liquid phase. What's left is a dry, stable cake of peptide with very little residual moisture.
Why it matters
Peptides in solution are far less stable than in dry form. Lyophilized material tolerates storage and transport much better, which is why a lab reconstitutes it only when it's ready to use. For keeping it stable afterward, see storing research peptides.
