The table shows the values of the constants we assigned to each of the metabolites that were originally variables in the Reed-Nijhout model
Geographic and Publication Bias The most consequential limitation in Selank research is structural rather than purely scientific: Overwhelming majority of studies conducted exclusively at Russian and Ukrainian institutions Most clinical data published in Russian-language journals, with only abstracts accessible through international databases like PubMed No independent international replication of clinical findings has been published in peer-reviewed Western literature Clinical study methodologies are difficult to fully assess given limited access to complete publications Mechanistic Understanding Gaps Fundamental aspects of Selanks mechanism remain unresolved: No single primary receptor or binding target has been definitively identified Whether anxiolytic effects are primarily driven by GABAergic modulation, enkephalin pathway effects, monoamine changes, or BDNF upregulation or some combination remains debated Active metabolite contributions (RP, GP, PGP fragments) to total biological activity are not fully characterized Tissue-specific receptor interactions require further clarification across brain regions Long-Term Safety Considerations Critical safety questions remain inadequately addressed: Chronic use effects beyond short-term protocols unstudied even in animal models Immunogenicity risk cannot be excluded given the peptides partial homology to immunoglobulin fragments Interaction potential with psychiatric medications, including benzodiazepines, is only partially characterized Reproductive and developmental toxicity has not been systematically investigated Cancer cell interaction and tumor progression effects are unstudied Regulatory & Competitive Sport Status FDA Position Selank has not received FDA approval for any indication in the United States: Classified as an unapproved drug substance under FDA jurisdiction Not recognized as GRAS (Generally Recognized as Safe) Not approved for human use, medical compounding, or veterinary applications in the US Approved in Russia (2009) for generalized anxiety disorder
