Cerebrolysin and Semax both come up in the same conversations; they overlap on Neurotrophins. Cerebrolysin: Cerebrolysin is a neuropeptide preparation that mimics the brain's own neurotrophic factors to support neuronal protection, repair, and plasticity. Semax: Semax is a synthetic peptide nootropic and neuroprotective agent based on a fragment of adrenocorticotropic hormone (ACTH), developed in Russia and used there clinically for cognition, stroke, and brain injury.
Cerebrolysin is a neuropeptide preparation that mimics the brain's own neurotrophic factors to support neuronal protection, repair, and plasticity. Widely used across Europe and Asia for stroke, dementia, and traumatic brain injury, it is one of the most established neurotrophic therapies in clinical practice. For those focused on brain health and neuroregeneration, Cerebrolysin is a uniquely biologically active peptide preparation.
Semax is a synthetic peptide nootropic and neuroprotective agent based on a fragment of adrenocorticotropic hormone (ACTH), developed in Russia and used there clinically for cognition, stroke, and brain injury. It rapidly raises the brain's own growth factors, BDNF and NGF, and modulates dopamine and serotonin, underpinning its reputation for sharper focus, memory, and mental drive. Delivered as a nasal spray and stripped of any hormonal activity, it pairs cognitive support with genuine neuroprotection.
both fingerprints on one instrument; where the marks line up the two compounds work the same lever, where a slot goes dark only one of them touches it. read straight from each entry's affinity table; nothing here is invented.

strengths are the entries' qualitative ratings (strong / moderate / weak); Ki and EC50 figures appear where an entry records them.
easiest to source: Semax is currently listed by more trusted vendors (7), so it's the simpler one to get hold of. for effects and safety, read each full entry; this is educational, not medical advice.
