1. Telomerase Activation and Chromosomal Elongation in Vitro
In 2003, Khavinson et al. demonstrated that Epitalon reactivated telomerase in human fetal fibroblasts, causing telomere lengthening and extending proliferative capacity from 34 to more than 44 cell divisions.

An average 33% increase in telomere length was observed, indicating a potential reversal of cellular aging.
2. Exceeding the Hayflick Limit
In studies, fibroblasts treated with Epitalon continued to replicate beyond the normal limit for human cells (32–50 divisions), showing extended division capacity.

3. Effects on Human Lymphocytes
Epitalon was able to influence chromatin structure and protect against mutagens in lymphocytes from elderly adults.

A 2019 experiment showed that telomere loading in human lymphocytes increased by 18% to 156% in many cases, although this varied depending on the age of the individuals.

4. Results in Laboratory Animals
In aged mice and rats, Epitalon reduced chromosomal abnormalities, increased antioxidant enzymes, and prolonged maximum lifespan (~13%).

In leukemia-prone mice, the treatment significantly reduced the number of tumors.
5. Human Clinical Studies
In treated adults aged 60–80 years, an increase in telomere length was observed in blood cells, similar to the crude epithalamin extract.

A study in tuberculosis patients showed a protective effect against future chromosomal damage, although it did not repair existing chromosomal damage.
Several controlled trials in the elderly demonstrated a reduction in mortality (up to 28%) after 9–12 years of follow-up, with improvements in cardiovascular health, metabolism, and sleep.

6. Scientific Reviews and Safety
A recent review from 2025 confirms telomerase activation, antioxidant protection, and geroprotective potential.

The Alzheimer's Drug Discovery Foundation notes that all clinical studies originate from the same Russian group, with a lack of independent replication and a lack of formal Phase I/II human trials.
