- Subcutaneous Injection
- 95–98%
- 90–120 minutes
- Minimal (bypasses gut and liver)
- Requires sterile technique, needle handling, site rotation
- Highest bioavailability and most reproducible plasma levels. Reference standard for dosing precision
- Nasal Spray
- 40–60%
- 20–30 minutes
- Mucosal enzymes, mucociliary clearance
- Non-invasive, excipient-dependent, affected by nasal congestion
- Moderate bioavailability with convenience trade-off. Formulation quality significantly impacts absorption
- Oral (capsule/tablet)
- <5%
- Not applicable (minimal absorption)
- Gastric acid, pepsin, intestinal peptidases
- Easiest administration but ineffective delivery
- Clinically non-viable. Enzymatic degradation prevents systemic absorption
- Intravenous Bolus
- 100%
- Immediate
- None (direct systemic entry)
- Impractical for routine use, requires medical setting
- Maximum bioavailability but logistically unsuitable for most research protocols
