Most people think Selank just «calms you down». But that’s not really what’s happening.
In a 2016 study, researchers looked at gene expression in the frontal cortex after a single dose. Within 60 minutes, 45 genes changed. 22 were still active 3 hours later. A whole signalling network.
Selank modulates GABA-A receptors, but it also seems to go further:
* affects stress-response systems
* slows enkephalin breakdown
* increases BDNF expression
If you’ve ever combined it with Semax there might be a reason it works so well.
Semax → increases BDNF
Selank → reduces noise in the system
Together, they may reinforce each other.
