Pinealon

Epithalon (also spelled Epitalon) is a synthetic four-amino-acid peptide, Ala-Glu-Asp-Gly (AEDG), modeled on a natural pineal gland extract. It came out of decades of Russian gerontology research led by Vladimir Khavinson and is marketed as an anti-aging compound that supposedly switches telomerase back on. It has no approval from the FDA, EMA, or other Western regulators, and the human evidence is thin.

Cortagen is a synthetic tetrapeptide (Ala-Glu-Asp-Pro, AEDP) from Vladimir Khavinson's Russian peptide bioregulator program, designed as the defined-sequence stand-in for Cortexin, an older cattle brain cortex extract used in Russian neurology. It is studied mostly for nerve repair, brain function and aging, and it is not approved by the FDA or EMA. Real evidence is limited to animal experiments and Russian-institute work, with no Western randomized human trials.

Chonluten is a synthetic tripeptide (Glu-Asp-Gly, EDG) from the Khavinson bioregulator family, pitched as the lung and bronchial peptide, derived conceptually from the same program that produced Epitalon and Cortagen. It is researched for respiratory tissue and age-related lung decline, and it has no FDA or EMA approval. The evidence is essentially all preclinical or uncontrolled Russian clinical observation, with no randomized human trials.

Thymalin is not a single peptide but a polypeptide complex extracted from calf thymus, developed in the Soviet and Russian peptide-bioregulator tradition associated with Vladimir Khavinson. It is used in Russia and several post-Soviet countries to correct immune deficiency and is promoted as a geroprotector, with claimed effects on T and B lymphocytes, infection rates and aging. Outside that region it has no FDA or EMA approval, and the strongest human data come from a small number of studies, several from the originating research groups.

Vilon is a synthetic dipeptide, Lys-Glu (lysine-glutamic acid), one of the short peptide bioregulators developed by Vladimir Khavinson's group at the St. Petersburg Institute of Bioregulation and Gerontology in Russia. It is marketed in the anti-aging and immune-support space as a thymus-related bioregulator, but the real evidence base is almost entirely Russian animal studies. There are no registered Western randomized human clinical trials, so any human claims should be read with heavy skepticism.

Cartalax is a synthetic tripeptide (Ala-Glu-Asp, or AED) from the Khavinson family of short peptide bioregulators, studied as a cartilage and connective-tissue regulator. It is a research compound, not an approved drug, and no registered human clinical trials exist.
