            "a": "Store reconstituted peptide solution in the original vial, refrigerated at 2–8°C (36–46°F), kept upright and shielded from light, since degradation speeds up once powder is dissolved into liquid. Limit freeze-thaw cycling: freezing and re-thawing an already-reconstituted solution puts mechanical stress on the material, so aliquot into single-use portions in advance if you expect multiple sessions. Keep the vial in its original opaque or amber packaging, or inside a closed fridge, and minimize bench time under room light. Write the reconstitution date and diluent on the vial, since degradation is often invisible — a solution can look normal well past its stability window, so tracking age by date is more reliable than checking appearance. See our storage guide for more detail."
