Peptide Storage Guide

Lyophilized (Powder) Form

Store sealed vials at −20°C in a dry, dark location. Most peptides remain stable for 18–24 months under these conditions.

Reconstitution

Use bacteriostatic water (0.9% benzyl alcohol) for most peptides. Inject the solvent slowly down the inside wall of the vial — never directly onto the powder — and swirl gently. Do not shake.

Reconstituted Storage

• 2–8°C (refrigerator): 14–30 days for most peptides
• −20°C (freezer): up to 90 days; avoid repeated freeze-thaw cycles

Things to Avoid

Direct sunlight, heat above 25°C, repeated agitation, and contamination through repeated needle entries with non-sterile syringes.

Shipping
