Mechanism of Action
Cortagen (Ala-Glu-Asp-Pro) is a synthetic tetrapeptide belonging to the Khavinson family of peptide bioregulators — short peptides proposed to regulate gene expression in a tissue-specific manner. The bioregulator hypothesis, developed by Professor Vladimir Khavinson over decades of research at the St. Petersburg Institute of Bioregulation and Gerontology, proposes that short peptides (2-4 amino acids) can penetrate cell membranes and nuclear envelopes, interact directly with DNA in a sequence-specific manner, and modulate transcription of tissue-relevant genes.
Cortagen is specifically designed to target neurons of the cerebral cortex. According to the Khavinson model, the AEDP tetrapeptide sequence has complementarity to specific DNA sequences in gene promoter regions active in cortical neurons. Upon binding to these regulatory elements, Cortagen is proposed to modulate chromatin structure and transcription factor access, influencing the expression of genes involved in neuronal function, synaptic transmission, antioxidant defense, and protein synthesis. The tissue specificity — cortex rather than other brain regions or body tissues — is attributed to the unique chromatin accessibility and transcription factor environment in cortical neurons that determines which genes are available for regulation.
Preclinical studies from Russian research programs have reported that Cortagen treatment improves cognitive function, enhances learning and memory, and provides neuroprotection in models of cerebral ischemia and age-related cognitive decline. The proposed mechanism involves restoration of age-related declines in protein synthesis in cortical neurons, enhancement of antioxidant enzyme expression (SOD, catalase, GPx), and improved synaptic function through upregulation of synaptophysin and other synaptic proteins. It should be noted that the peptide bioregulator field remains controversial in Western pharmacology — while the Russian research program is extensive, the proposed direct DNA-binding mechanism has not been independently validated through the standard molecular biology methods expected in Western peer-reviewed literature.

AEDG Peptide
A tetrapeptide (Ala-Glu-Asp-Gly) identical to Epithalon's core active sequence — effectively the same compound. Studied for telomerase activation and pineal gland regulation, promoting melatonin production and potentially slowing cellular aging through telomere maintenance. Part of the Khavinson bioregulator peptide family developed in St. Petersburg.
Cerebrolysin
A mix of brain-derived peptides and amino acids from pig brains. Widely used worldwide for stroke recovery, brain injury, and brain degeneration. Mimics the body's natural brain-supporting factors to help neurons survive, form new connections, and grow.
CJC-1295 (no DAC)
One of the most popular growth hormone peptides, often called Mod GRF 1-29. Instead of injecting growth hormone directly, this tells your pituitary gland to release more of its own GH naturally. This is considered healthier than injecting GH directly because your body keeps its normal feedback systems intact. Usually combined with Ipamorelin for much stronger effects — the two work together better than either alone.
CJC-1295 + Ipamorelin
The most commonly prescribed peptide combination in anti-aging and regenerative medicine. Pairs the GHRH analogue CJC-1295 (Mod GRF 1-29) with the selective ghrelin-mimetic Ipamorelin for synergistic, pulsatile growth hormone release. Exploits two complementary signaling pathways — cAMP (GHRH) and calcium/PLC (ghrelin receptor) — to amplify GH pulses while maintaining minimal side effects.
