- Intranasal
- 50–100
- 30–60 minutes
- 6–12 hours
- 60–75%
- Preferred route for CNS research. Bypasses blood-brain barrier via olfactory transport, lowest dose requirements, minimal systemic exposure
- Subcutaneous
- 200–500
- 60–120 minutes
- 8–16 hours
- 40–55%
- Standard route for chronic studies. Consistent absorption, suitable for implanted minipumps, higher doses required due to hepatic metabolism
- Intraperitoneal
- 300–600
- 45–90 minutes
- 6–10 hours
- 35–50%
- Common in rodent studies but higher dose variability. Absorption affected by injection site and animal activity level
- Intravenous
- 100–200
- 10–20 minutes
- 4–8 hours
- 100% (reference)
- Rarely used except for pharmacokinetic studies. Short duration limits behavioral testing utility
- Intranasal administration dominates published Selank research. The olfactory epithelium contains neurons projecting directly to limbic structures. Hippocampus, amygdala, prefrontal cortex. Allowing peptides to reach target regions within minutes without crossing the blood-brain barrier systemically. This route reduces required doses by 50–70% compared to peripheral injection while producing equivalent or superior CNS effects.
- Subcutaneous administration suits chronic studies where daily intranasal dosing would cause nasal irritation or handling stress. Osmotic minipumps delivering continuous subcutaneous infusion eliminate repeated injections entirely. Particularly valuable in long-term neuroplasticity studies where minimizing stress variables is critical.
- Real Peptides supplies Selank Amidate Peptide as lyophilized powder requiring reconstitution with bacteriostatic water. Reconstituted solutions remain stable for 28 days refrigerated at 2–8°C. Sufficient for most chronic administration protocols. Researchers conducting extended studies should prepare fresh solutions monthly to maintain peptide integrity.
