THE COGNITIVE STACK | Selank & SemaxThe Cognitive Stack pairs two of the most researched nootropic peptides — Selank and Semax — into a single research bundle. Both are derived from endogenous neuropeptides and have been studied extensively for their complementary effects on cognition, mood, and neuroprotection, with Selank targeting anxiety and memory consolidation and Semax driving BDNF upregulation and cognitive performance.What's Included Selank 10mg — tuftsin-derived anxiolytic peptide studied for anxiety reduction, memory enhancement, and BDNF modulation without sedation Semax 10mg — ACTH-derived neuropeptide studied for rapid BDNF and NGF upregulation, cognitive enhancement, and neuroprotection Research Highlights Studied for complementary nootropic effects — Selank's anxiolytic action alongside Semax's cognitive drive Investigated for synergistic BDNF modulation and neuroplasticity support Researched for enhanced learning, memory consolidation, and working memory in preclinical models Explored for stress resilience and mood stabilisation via dopaminergic and GABAergic pathways Examined as one of the most referenced nootropic peptide pairings in cognitive research literature Specification Includes: 1 × Selank 10mg + 1 × Semax 10mg Purity: >99% by HPLC (both peptides) Form: Lyophilised powder Storage: 2–8°C, protect from light For research purposes only For laboratory research use only. Not for human consumption. Limitless Labs supplies research-grade peptides to verified researchers.
