Your nervous system runs on chemical messengers — serotonin, dopamine, GABA and others — and on proteins like BDNF that govern how readily the brain adapts and forms connections. Peptides in this category are studied for how they interact with that signalling. They aren't stimulants: the research interest is in how steadily those systems run, not in pushing them harder.
Semax research leans toward attention, mental clarity and the signalling involved in learning. Selank research leans toward the stress-response and calming pathways — GABA in particular. In practice people often describe the difference as sharper versus steadier. Which one suits you depends on whether the problem is holding concentration or staying level under pressure, and your provider will work through that with you.
They're studied together as well as separately, on the reasoning that the pathways they touch are complementary rather than overlapping. Whether a combined approach makes sense for you is a decision for your Medical Practitioner after reviewing your goals and health history.
