Short plasma half-life typical of tetrapeptides; biological effects persist for weeks through epigenetic chromatin remodeling modifications; metabolized to constituent amino acids (lysine, glutamic acid, aspartic acid, alanine)
Resistant to intestinal proteolysis when administered orally (weakly hydrolyzed by intestinal peptidases); efficient absorption from intramuscular injection sites; penetrates cytoplasmic and nuclear membranes to reach cell nuclei and nucleoli

5-10 mg
10-20 day course, repeated 1-3 times per year
Subcutaneous injection is the most common route used in practice, mirroring the dose used in the Russian intramuscular clinical literature [6]. Typically run as a short 10-20 day course a few times per year [3].
Intramuscular dosing of 5-10 mg/day for 10-20 days is the form used in Khavinson's original Russian clinical work in older adults [6].
10-day course (50-100 mg total)
Reflects the Khavinson-laboratory bioregulator course used in practice: a total of 50-100 mg of the KEDA tetrapeptide delivered over 10 days. Livagen has no standardized human clinical dosing; evidence is largely preclinical [6].
Applications
Bestsuited for
Longevity Enthusiasts
If you're serious about healthy aging and want to support your cells at the deepest level, Epithalon targets one of the fundamental mechanisms of cellular aging—telomere shortening. It's like giving your cells' protective caps a little extra reinforcement.
Sleep Quality Seekers
Epithalon helps regulate melatonin production by supporting your pineal gland. Many users report better sleep quality and more consistent sleep-wake cycles, especially those who've noticed their sleep getting worse with age.
Those Concerned About Oxidative Stress
Beyond its telomere effects, Epithalon acts as an antioxidant. If you're exposed to environmental stressors, have a demanding lifestyle, or simply want extra cellular protection, this peptide offers multiple mechanisms of support.
Immune System Support (Age-Related)
As we age, our immune system naturally weakens—a process called immunosenescence. Research suggests Epithalon may help maintain immune function by supporting the thymus and immune cell health, potentially keeping your defenses stronger as you age.
Comprehensive geroprotective therapy targeting epigenetic chromatin remodeling in aging cells
Livagen is particularly well-suited for individuals focused on comprehensive geroprotective therapy targeting epigenetic chromatin remodeling in aging cells. Research and clinical experience suggest meaningful benefits in this area when used as part of a comprehensive treatment approach.
Supporting liver function and hepatoprotection in the context of aging
Livagen is particularly well-suited for individuals focused on supporting liver function and hepatoprotection in the context of aging. Research and clinical experience suggest meaningful benefits in this area when used as part of a comprehensive treatment approach.
Restoring protein synthesis and ribosomal function in elderly individuals
Livagen is particularly well-suited for individuals focused on restoring protein synthesis and ribosomal function in elderly individuals. Research and clinical experience suggest meaningful benefits in this area when used as part of a comprehensive treatment approach.
Khavinson bioregulator protocols for anti-aging and longevity
Livagen is particularly well-suited for individuals focused on khavinson bioregulator protocols for anti-aging and longevity. Research and clinical experience suggest meaningful benefits in this area when used as part of a comprehensive treatment approach.

Safety Overview
Epithalon has shown a favorable safety profile across decades of research, primarily conducted in Russia. Studies spanning up to 15 years of follow-up have reported no severe adverse events in older adults using Epithalon or its natural precursor Epithalamin. The peptide appears well-tolerated with minimal side effects, mostly limited to mild injection site reactions. However, large-scale clinical trials outside of Russia are still needed.
Contraindications
xPregnancy or planning to become pregnant
xCurrently breastfeeding
xActive cancer or history of cancer
xKnown allergy to peptide components
xChildren and adolescents
Livagen (a liver-derived peptide extract) carries a safety profile established through decades of use in Eastern European hepatology and gastroenterology clinics. As an organ-derived extract rather than a synthetic single peptide, it contains multiple bioactive components promoting hepatocyte regeneration and cytoprotection. Adverse events are minimal in reported clinical experience—mild gastrointestinal upset occurring in <5% of patients. The compound shows no hepatotoxicity, nephrotoxicity, or immunosensitization in available safety surveillance data from thousands of patients.
xKnown hypersensitivity to peptide bioregulators or constituent amino acids (lysine, glutamic acid, aspartic acid, alanine)
xPregnancy and breastfeeding — insufficient reproductive safety data
xActive autoimmune conditions in flare without physician supervision
xConcurrent use of opioid medications — Livagen's enkephalinase inhibition may alter opioid metabolism
