Can I freeze a reconstituted peptide to make it last longer?

It is possible for some peptides, but freezing and thawing an aqueous solution introduces its own stresses, and repeated freeze-thaw cycles are discouraged because they can degrade the peptide. If a solution is frozen, it is usually done once and thawed once. For most people, refrigerating and using within the standard window is simpler and safer.
