- The table below clarifies nomenclature, mechanism, and evidence quality for what remains a single peptide despite varied naming conventions.
- Chemical Identity
- Nonapeptide: Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu
- Identical molecule. Abbreviation versus full name
- Mechanism of Action
- HPA axis modulation; cortisol reduction; serotonin metabolism influence
- No mechanistic difference
- Typical Research Dose
- 25–100 µg IV or SC
- Dosing protocols are identical across literature
- Half-Life
- ~15–20 minutes (IV/SC)
- Short half-life requires timing precision
- Human Trial Evidence
- Mixed results; positive trials mostly pre-1995 with weak controls
- Evidence quality does not favour one name over the other
- Commercial Availability
- Sold as lyophilised powder for reconstitution
- Same sourcing and preparation requirements
