Frequently asked questions

What is a bioregulator?

In these encyclopedia entries, bioregulators are tissue-focused peptides or peptide preparations studied for regulation of cellular activity.

Which bioregulators were developed by Khavinson?

The stored Khavinson-flagged entries are Bronchogen, Cardiogen, Cartalax, Chonluten, Cortagen, Epitalon (Epithalon), Livagen, Ovagen, Pancragen, Pielotax, Pinealon, Prostamax, Testagen, Thymalin, Thymogen, Ventfort, Vesilute, Vesugen, Vilon. Their entry pages contain the stored development attribution and its sources.

Which entries are included in this directory?

Entries are included when their stored classification identifies them as bioregulators, supported by stored entry text or a cited source. General supplements and antioxidants are not included simply because they are studied in longevity research.

What is a Cytogen?

The synthetic category of bioregulator peptides, also called tissue-specific peptides. Cytogens are fully synthesized versions of the bioactive peptide sequences identified within natural tissue extracts. The stored Epitalon (Epithalon) entry describes a synthetic tetrapeptide.

What does Khavinson Peptides mean?

The informal collective name for the bioregulator peptides developed by Dr. Vladimir Khavinson and his research team at the St. Petersburg Institute of Bioregulation and Gerontology.

Is it Epitalon or Epithalon?

Epitalon and Epithalon are spellings of the same compound. Epitalon is the canonical name used here. Both refer to the Ala-Glu-Asp-Gly (AEDG) tetrapeptide.
