It is the main peak's share of the total peak area in a chromatogram. It is not the same as net peptide content. See What purity percentages mean.

Keep sealed freeze-dried vials cold, dry and away from light. Let a cold vial reach room temperature before opening to avoid condensation.

Dry powder is generally more stable than a solution, so it travels better. Cold weather in transit is generally not a concern for sealed lyophilised powder.

We replace or reship at our discretion; this is a replacement, not a refund.
