Epithalon vs Pinealon

Epithalon was synthesised from the amino-acid composition of epithalamin, a bovine pineal extract, and most of its literature comes from the group that developed it ^1,4. In human fetal fibroblast cultures (cell data), it induced the catalytic subunit of telomerase, telomerase activity and telomere elongation ³. In fluorescence studies in HeLa cells (cell data), labelled Epithalon entered the nucleus and bound preferentially to DNA sequences containing CNG motifs ⁹. In organotypic rat pineal cultures, it stimulated the proliferation marker Ki-67 and the transcription factor CGRP ⁸.

The FDA's 2026 review found no studies of epitalon in people with insomnia, no pharmacokinetic data and no human safety data, and judged mouse toxicology too limited to inform cancer risk ¹.

Pinealon (Glu-Asp-Arg) was studied mainly in cells. In cerebellar granule cells, neutrophils and PC12 cells (cell data), it limited reactive oxygen species accumulation and necrotic cell death, with delayed ERK1/2 activation and cell-cycle changes; the authors proposed direct interaction with the genome ⁵. In rats whose mothers were given a methionine load during pregnancy (animal data), offspring given Pinealon showed changes in spatial-orientation and learning measures and lower reactive oxygen species in isolated cerebellar neurons ⁶. A 2020 review by the same group summarises reported effects on signalling pathways and antioxidant-enzyme synthesis ⁷.

Human evidence is a single small Russian-language study in 32 people aged 41 to 83 with chronic multimorbidity and an organic brain syndrome in remission, which reported changes in biological-age indicators and, alongside them, prooxidant activity on chemiluminescence and lower CD34+ cell markers in blood ¹⁰. No registered trials were found ¹³.
