BPC-157 nasal spray
Angiogenic repair peptide — intranasal pharmacokinetics
A pentadecapeptide fragment of human gastric juice protein, studied for endothelial recovery, tendon repair, and gut-lining cytoprotection. Fourteen studies reviewed; emphasis on bioavailability via transmucosal absorption.

Selank
Heptapeptide anxiolytic and GABA-ergic modulator
A synthetic analogue of tuftsin studied by the Institute of Molecular Genetics (Moscow) for its anxiolytic profile without sedation or dependence. Includes comparative analysis with benzodiazepine class compounds.

Semax
ACTH(4-10) heptapeptide — BDNF and NGF expression
A melanocortin-derived peptide researched for cognitive enhancement, neuroprotection, and upregulation of brain-derived neurotrophic factor. Reviewed alongside emerging stroke-recovery literature from Eastern European trials.

PT-141 (Bremelanotide)
Melanocortin receptor agonist
A cyclic heptapeptide derivative of α-MSH studied for central nervous system activation of sexual arousal pathways via MC3R/MC4R. Covers FDA-approved clinical trial data alongside broader research applications.

Oxytocin
Social-cognition neuropeptide and the intranasal delivery paradigm
A cyclic nonapeptide synthesized in the hypothalamus, studied for effects on trust, empathic accuracy, and face processing via OXTR and partial V1a cross-reactivity. Reviews both the behavioral findings and the methodological caveats around intranasal central exposure.

DSIP (Delta Sleep-Inducing Peptide)
Slow-wave sleep modulation and HPA-axis literature
A nonapeptide originally isolated from rabbit cerebral venous blood during electrically-induced sleep. Reviews four decades of literature on EEG delta-wave facilitation, HPA-axis dampening, withdrawal-syndrome applications, and stress-adaptation findings.

Nasal stack protocols
Rationale and separation when combining intranasal peptides
How researchers separate nasal dosing windows, rotate peptide pairs, and manage receptor downregulation across multi-compound protocols. Includes timing grids for the most common two- and three-compound stacks.
Each entry cites primary sources. PubMed IDs are provided in-text. Where human trial data is unavailable, we note preclinical scope explicitly.
Entries are reviewed when new literature becomes available. Revision dates are noted at the foot of each article. No AI summary generation.
All compounds are sold for in-vitro research use only. Nothing here constitutes medical advice or treatment recommendation.
