The complete inventory of original Russian peptide bioregulators. Filter by body system, type, or health goal.
Cortexin
Кортексин
Cortexin is a complex of water-soluble polypeptide fractions extracted from the cerebral cortex of young cattle, with molecular weights ranging from 1,000 to 10,000 Daltons. These low-molecular-weight neuropeptides are capable of crossing the blood-brain barrier and exerting tissue-specific effects on the cerebral cortex. The peptide complex modulates neuronal metabolism, regulates neurotransmitter balance (particularly serotonin, dopamine, and amino acids), and restores bioelectrical activity in the brain. Cortexin has been extensively studied in Russia for over 20 years and is used clinically for various neurological and neurodevelopmental conditions.
Cerluten
Церлутен
Cerluten is a natural peptide bioregulator extracted from the cerebral cortex of young animals, containing tissue-specific, low-molecular-weight peptides that support comprehensive brain and central nervous system function. Once absorbed, these peptides interact with specific regions of neuronal DNA, acting as epigenetic switches that activate genes responsible for brain repair, protein synthesis, and cellular regeneration. Cerluten enhances metabolic efficiency within brain tissue, provides antioxidant protection against oxidative damage (particularly critical for the brain), regulates peroxide oxidation, and supports microcirculation to ensure neurons receive adequate oxygen and nutrients. It has been shown to improve synaptic plasticity, neurotransmitter regulation, and overall CNS resilience.
Pinealon
Пинеалон
Pinealon is a synthetic tripeptide bioregulator composed of Glutamic Acid, Aspartic Acid, and Arginine (Glu-Asp-Arg), also known as EDR peptide. Originally studied in Russia and derived from or inspired by pineal gland tissue extracts, Pinealon is designed to optimize pineal gland and overall brain function. Due to its small molecular size, it penetrates cellular and nuclear membranes to directly interact with DNA, modulating gene expression and protein synthesis in neurons. It enhances pineal gland activity (including melatonin production), optimizes neurotransmitter function (serotonin, dopamine, GABA, acetylcholine), provides comprehensive neuroprotection by reducing oxidative stress and supporting mitochondrial function, and influences the MAPK/ERK signaling pathway. Pinealon is recognized as a powerful nootropic with applications in cognitive enhancement and age-related neuroprotection.
Epithalamin
Эпиталамин
Epithalamin is a natural polypeptide extract from the bovine pineal gland, representing the "Gold Standard" of Khavinson bioregulators. It regulates the entire neuroendocrine system and exhibits profound anti-aging effects. Epithalamin increases telomerase activity (the enzyme that maintains and rebuilds telomere length), directly elongates telomeres in cells, and normalizes melatonin and cortisol secretion patterns. It modulates immune function, activates cell survival pathways, and has been shown in animal studies to extend lifespan by up to 25-40%. Some human clinical trials in Russia suggest reduced overall and cardiovascular mortality. Epithalamin works by restoring the function of the pineal gland, which acts as the body's biological clock and regulates circadian rhythms, reproductive aging, and systemic homeostasis.
Endoluten
Эндолутен
Endoluten is a natural peptide bioregulator extracted from the pineal gland of young animals, representing the oral equivalent of Epithalamin (the injectable gold standard). It contains peptide complex A-8, consisting of low-molecular-weight peptides with tissue-specific action on the pineal gland. Endoluten works by supporting the pineal gland's natural production of melatonin and other regulatory hormones, rather than supplying melatonin exogenously. It normalizes all cyclic processes in the body—including sleep-wake cycles, hormonal balance, reproductive function, and immune regulation. Due to its potency, Endoluten is typically taken less frequently than other bioregulators (e.g., every 3 days). It is recommended for systemic bioregulation, cancer risk reduction, electromagnetic stress mitigation, and overall longevity support.
Epitalon
Эпиталон
Epitalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) that is the active component of Epithalamin, confirmed to exist endogenously in pineal gland extracts in 2017. It is the most researched synthetic anti-aging peptide in the world. Epitalon activates the telomerase enzyme by inducing expression of TERT gene components, leading to telomere elongation at the ends of chromosomes—the protective caps that shorten with each cell division and contribute to cellular aging. Studies show it can increase telomere length by an average of 33%, though results vary among individuals. Epitalon also regulates melatonin synthesis via pineal gland support, improving sleep and hormonal balance. It has antioxidant properties, enhances immune function, and may reduce the risk of age-related neurodegenerative diseases.
Thyreogen
Тиреоген
Natural peptide complex from the thyroid gland. Normalizes thyroid function regardless of hypo- or hyperthyroidism.
Thymalin
Тималин
Thymalin is a polypeptide complex extracted from the thymus gland of young calves. It is a potent immunomodulator used clinically to restore and enhance cellular immunity, particularly in individuals with compromised immune systems. The thymus gland is critical for T-lymphocyte maturation, and Thymalin supports this process by stimulating T-cell differentiation, increasing natural killer (NK) cell activity, and normalizing the T-helper/T-suppressor ratio. It has been used for over four decades in Russia with an excellent safety profile. Thymalin is beneficial for acute and chronic infections, post-radiation recovery, cancer adjuvant therapy, and general immune optimization. Its efficacy is dependent on adequate zinc levels in the body.
Vladonix
Владоникс
Vladonix is a natural peptide bioregulator extracted from the thymus gland of young animals, representing the oral equivalent of Thymalin (the injectable form). It contains peptide complex A-6, which supports the thymus gland's function as the "master regulator" of cellular immunity. Vladonix stimulates T-lymphocyte production, normalizes cellular immunity parameters, boosts protein synthesis in immune cells, and has been shown to have oncoprotective (cancer-preventive) properties. It is particularly beneficial for individuals recovering from chemotherapy, radiation, viral infections, or those with autoimmune diseases. Vladonix is suitable for long-term use as part of a comprehensive immune support protocol, with intensive and maintenance phases.
Crystagen
Кристаген
Synthesized peptide complex (Pro-Glu-Asp) for rapid immune correction.
Ventfort
Вентфорт
Ventfort is a natural peptide bioregulator containing peptide complex A-3, extracted from the blood vessels (specifically the aorta) of young animals. It is designed to strengthen the vascular wall, restore elasticity of endothelial cells, and support overall cardiovascular health. Ventfort regulates lipid metabolism, helps reduce atherosclerotic plaques, normalizes blood pressure, and improves microcirculation throughout the body. Clinical studies in patients with atherosclerosis have shown significant improvements in vascular function and reduction in inflammatory markers. Ventfort is considered suitable for long-term use as part of a comprehensive cardiovascular health protocol.
