Handling & reference data

Route in published researchSubcutaneous injection is the route most commonly described in the research literature.

Reported half-life~20–30 h

Published clinical / research context (not instructions)Reported research ~20–50 mcg daily. Potent — carries hypoglycaemia risk.

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.
