It was developed in Russian research and is studied mainly in a cognitive and neuroprotective context.<\/p>\n<h2>What does the research examine?<\/h2>\n<p>Studies have examined Semax in the contexts of attention, memory, and neural protection, as well as its effect on factors such as BDNF (a protein linked to neural plasticity). It is considered one of the most studied in the nootropics field, but most of the data is still early and outside Israel.<\/p>\n<h2>Why is it studied alongside Selank?<\/h2>\n<p>Semax \u05d5-<a href=\"\/en\/what-is-selank\/\">Selank<\/a> They come from the same school of research and are sometimes examined together \u2014 one more in a cognitive context, the other more in the context of emotional regulation.<\/p>\n<h2>Frequently asked questions<\/h2>\n<p><strong>Is Semax a hormone?<\/strong><br \/>No \u2014 it is based on a fragment of ACTH but without the classic hormonal activity.<\/p>\n<p><strong>How is it reconstituted?<\/strong><br \/>From powder, using <a href=\"\/en\/product\/bac-water\/\">bacteriostatic water<\/a> and<a href=\"\/en\/calculator\/\">our dilution calculator<\/a>.<\/p>\n<p>For the research product details: <a href=\"\/en\/product\/semax\/\">Semax<\/a>.
