Intranasal
Also known as: nasal route · intranasal spray · IN
Delivery through the nasal lining — the route some peptides such as Semax and Selank are studied via.
Intranasal delivery introduces a solution through the lining of the nose, which is thin and well-supplied with blood, and offers a potential direct route toward the brain along the olfactory pathway.
It is the route through which nootropic peptides such as Semax and Selank are commonly studied, often as a metered spray. This term is reference terminology only; products are for research purposes only.

A synthetic analog of a fragment of ACTH, studied for neuroprotection, focus and cognitive performance.
Selank

Bioavailability
The fraction of an administered dose that actually reaches circulation intact — low for oral peptides, higher for injection.
Subcutaneous
Into the layer of fat just beneath the skin — the route most peptide research protocols reference.
