Handling & reference data
Route in published researchIntranasal or subcutaneous.
Published clinical / research context (not instructions)Reported research ~200–600 mcg daily.
Storage (lyophilised)Lyophilised (freeze-dried) powder: refrigerate at 2–8 °C short-term, or freeze at −20 °C or below for long-term storage. Keep sealed and out of light.
Reconstituted solutionOnce reconstituted: keep refrigerated (2–8 °C), protect from light, do not freeze. With bacteriostatic water, commonly used within ~4 weeks; with plain sterile water, within ~24–48 h.
Worked reconstitution example (arithmetic only)e.g. 5 mg vial + 2 mL → 2.5 mg/mL.
