Epithalon Reconstitution: Method Comparison
Direct injection onto powder 90° (perpendicular) Vigorous shaking common Low if single-use vial 10–15% loss from mechanical shear Fast but degrades bioactivity. Not recommended for tetrapeptides Angled injection against wall 45° against glass Gentle rolling on

- Direct injection onto powder
- 90° (perpendicular)
- Vigorous shaking common
- Low if single-use vial
- 10–15% loss from mechanical shear
- Fast but degrades bioactivity. Not recommended for tetrapeptides
- Angled injection against wall
- 45° against glass
- Gentle rolling only
- Low with pressure equalisation
- <2% loss if done correctly
- Gold standard. Preserves peptide structure and minimises contamination
- Pre-dilution in separate vial
- N/A (mixed externally)
- Variable
- High. Multiple transfer steps
- 5–8% loss from oxidation exposure
- Introduces unnecessary contamination points. No advantage over wall method
- Room-temperature reconstitution
- Any angle
- Any method
- Moderate
- 20–30% loss within 48 hours
- Temperature is the deciding factor. Reconstitute at fridge temp or transfer immediately
