What Thymalin with epitalon is

The rare combination in this batch that was actually studied as a combination: 266 elderly people followed for six to eight years on thymalin and epithalamin, where the group given both had a 2.5-fold lower mortality rate than controls and a subgroup treated annually for six years had a 4.1-fold reduction. The trial was unblinded, single-centre, from one research group, has never been replicated, and the pineal component in it was a gland extract rather than the synthetic tetrapeptide sold today.

This page has to do something unusual: report an extraordinary claim from a real combination study and then say precisely why it is not settled. The study.

Mechanism: Thymalin is a peptide complex extracted from calf thymus and is claimed to restore thymic-dependent immune function. Epithalamin is a pineal peptide extract; epitalon is the synthetic tetrapeptide derived from that programme and is claimed to act on pineal function, melatonin rhythm and telomerase.

Regulatory history: Neither is approved in the United States. Both are produced and used in Russia within the peptide bioregulator programme, and are sold elsewhere as research chemicals.
