Research Comparison
Selank vs Semax
A side-by-side research comparison of Selank and Semax drawn from Cobalt Peptides' peptide database records.
Selank
Selank is a synthetic heptapeptide analog of the naturally occurring immune peptide tuftsin, developed by the Russian Academy of Sciences. This anxiolytic and nootropic peptide has been extensively studied for its ability to reduce anxiety, enhance cognitive function, and modulate immune responses without the side effects associated with traditional benzodiazepines. Selank works through complex interactions with GABAergic, serotonergic, and dopaminergic neurotransmitter systems, offering a unique mechanism for stress reduction and cognitive enhancement. Studies have demonstrated modulation of multiple neurotransmission-related genes and increased hippocampal BDNF expression, indicating meaningful neuroplasticity and neuroprotective effects with no known tolerance, dependence, or withdrawal.
Semax
Semax is a synthetic heptapeptide derived from the ACTH(4-10) fragment, developed in Russia and studied for its effects on the central nervous system. The published literature describes rapid increases in BDNF expression and modulation of dopaminergic and serotonergic signalling. Administered intranasally in study protocols, it is described as reaching the CNS via the olfactory epithelium and trigeminal pathways rather than crossing the blood-brain barrier. Semax is not an approved medicine in the United Kingdom. Supplied strictly as a research compound for laboratory use.
