Articles on Selank, the tuftsin analogue studied in neuroscience research, and on sourcing it in Canada for laboratory use.
What NGF and BDNF are, why precursor forms do the opposite of mature ones, why adult human neurogenesis is still contested, and exactly what the published Semax, Selank and P021 work measured.
Nootropic peptides explained: Semax, Selank, P021, PE-22-28 and DSIP compared by origin, mechanism and evidence, plus sourcing in Canada.
Semax vs Selank: two Russian-developed heptapeptides with the same Pro-Gly-Pro tail. What each is built from, what studies found, and Canadian sourcing.
