- Before selecting an administration route, researchers should understand how each method affects taste intensity, bioavailability, and protocol practicality. The following table compares intranasal, sublingual, and oral routes based on real-world user feedback and pharmacokinetic data.
- Intranasal (proper technique)
- 1–2 (minimal; only if runoff occurs)
- High (60–70% estimated)
- 10–20 minutes
- High. Fast, discreet, minimal taste
- Best option for most research protocols; taste is negligible when administered correctly
- Sublingual
- 7–8 (unavoidable; full taste receptor contact)
- Moderate-High (50–60%)
- 15–30 minutes
- Moderate. Requires 60–90 second hold; taste is pronounced
- Viable alternative when intranasal isn't suitable; expect metallic-bitter taste throughout hold
- Oral (swallowed immediately)
- 3–4 (brief contact during swallow)
- Very Low (5–15%; gastric degradation)
- 45–90 minutes (if effective at all)
- Low. Poor bioavailability makes this impractical for most protocols
- Not recommended; peptide degradation in stomach renders this route inefficient despite lower taste
- Buccal (cheek pouch hold)
- 4–5 (moderate; prolonged mucosal contact)
- Moderate (40–50%)
- 20–35 minutes
- Moderate. Less intense than sublingual but still noticeable
- Rarely used; offers no clear advantage over sublingual but produces similar taste intensity
