Clinical evidence — Human trial data existsWhat it is
A well-known circadian hormone available as a supplement or medicine in many countries; here in an injectable research form.
Melatonin is the well-known circadian hormone, normally taken orally. An injectable form is unusual and not the typical presentation.
Research context
Studied in relation to:
- Sleep/circadian support
Points in its favour in the literature:
- Well studied for sleep timing
- Widely available orally
Caveats and unknowns:
- Injectable form is not the usual product
- Can cause grogginess
- Interacts with some medications
Handling & reference data
Route in published researchUsually oral; the injectable form here is unusual.
Published clinical / research context (not instructions)Oral sleep use ~0.5–5 mg before bed; an injectable route is not standard.
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)If used in solution, e.g. 10 mg + 2 mL → 5 mg/mL.
