About Cortagen
Cortagen is a synthetic tetrapeptide bioregulator (Ala-Glu-Asp-Pro) targeting brain cortex function, developed by the St. Petersburg Institute of Bioregulation. Russian research suggests it improves cognitive function, stress resilience, and neurological recovery in aging populations. It is part of the same peptide bioregulator family as epitalon, vilon, and pinealon, designed to restore tissue-specific gene expression patterns.
About Sermorelin
A synthetic analog of growth hormone-releasing hormone (GHRH), this 29-amino acid peptide stimulates the pituitary gland to produce and secrete endogenous growth hormone through binding to GHRH receptors. It functions by mimicking the N-terminal bioactive portion of native GHRH, promoting pulsatile GH release while preserving the body's natural feedback mechanisms. Primary applications include diagnostic testing of pituitary function and therapeutic use in growth hormone deficiency.
