Nootropic & Cognitive Peptides

This category covers peptides studied in the context of cognitive function, neuroprotection, and central nervous system signaling. Semax is an ACTH(4-10) analog (Met-Glu-His-Phe-Pro-Gly-Pro) studied for BDNF and NGF upregulation in hippocampus and cortex, with preclinical data on ischemic neuroprotection and working memory. Selank is a synthetic heptapeptide analog of tuftsin (Thr-Lys-Pro-Arg-Pro-Gly-Pro) studied for anxiolytic and nootropic properties without sedation or dependence in preclinical models. Adamax is a nootropic peptide studied for neuroprotective mechanisms, NMDA receptor modulation, and memory consolidation in rodent models. PT-141 (Bremelanotide) is a cyclic melanocortin agonist targeting MC3R and MC4R receptors via central nervous system pathways, distinct from peripheral PDE5 mechanisms. Oxytocin is a hypothalamic nonapeptide studied for HPA axis modulation, social cognition research, and stress-response attenuation in preclinical behavioral paradigms. All compounds are supplied as lyophilized powders at a ≥99% purity target with lot-level HPLC documentation available on request. For laboratory research use only. Not for human or veterinary administration.
