- Direct powder injection
- Room temp (20–25°C)
- Inject onto powder bed
- No equalisation step
- 30–60 seconds
- High. Backflow contamination likely
- Fast but creates shear stress and foaming. Peptide purity drops to 78% by Day 28
- Wall injection (cold solvent)
- Refrigerated (2–8°C)
- Inject down vial wall
- Air drawn back before withdrawal
- 2–5 minutes
- Low. Pressure equalised before needle removal
- Gold standard. Maintains 94% purity through Day 28, prevents aggregation
- Pre-warmed solvent method
- Pre-warmed to 20°C
- 60–90 seconds
- Moderate. Faster dissolution but localised heat gradients
- Acceptable for immediate use only. Not recommended for multi-dose vials
