- Subcutaneous Injection
- 85–92%
- 30–45 minutes
- 2.7 hours
- Pharmacokinetic studies, dose-response trials, receptor-binding assays
- Gold standard for research requiring reproducible plasma levels and precise dose control
- Intranasal Spray
- 40–68%
- 45–60 minutes
- 1.9 hours
- Patient adherence studies, real-world efficacy comparisons
- High individual variability limits utility in mechanistic research
- Sublingual Administration
- 30–42%
- 60–90 minutes
- 1.5 hours
- Exploratory bioavailability studies
- Enzymatic degradation and inconsistent mucosal absorption make this route impractical for controlled trials
- Oral (Tablet)
- 12–18%
- 90–120 minutes
- 1.2 hours
- Rarely used. Under investigation for peptide stability optimization
- Hepatic first-pass metabolism destroys most peptide before systemic absorption; not viable with current formulations
