Bioregulators from the inside

The Russian 'bioregulator' school claims that short peptides (often 3–4 amino acids) carry organ-specific signals: epitalon for the pineal gland, thymogen for the thymus, cortagen for the nervous system. A fascinating idea — and almost entirely outside Western replication.

The grading is consistent across the whole category: preclinical or limited evidence, no large randomized trials, and a commercial machine that sells the whole shelf at once. That does not automatically mean 'does not work' — it means 'not proven'.

If you read only one entry, make it epitalon: the best example of the gap between a spectacular story (telomeres!) and a methodology that could not carry it.
