Peptide bioregulators, the Khavinson series
Short peptide bioregulators studied for tissue-specific gene expression in ageing models. Most are two to four residues — Vilon is a dipeptide, Epithalon a tetrapeptide — and the series turns on exactly those small differences. Much of the published work originates with a single research group, so look for independent replication before drawing conclusions.

What is a peptide bioregulator?
A very short peptide, typically two to four residues, from a body of work associating specific sequences with specific tissues. Epithalon (Ala-Glu-Asp-Gly) and Pinealon (Glu-Asp-Arg) are the best defined; some entries in the series are tissue preparations rather than single sequences.
Which of these are single defined peptides?
Epithalon, Pinealon, Vilon, Vesugen and Testagen have stated sequences. Thymalin and Prostamax are described as preparations, so their composition is not standardised across suppliers — record supplier and lot in any methods section.
How independent is the literature?
Limited. Much of it comes from one group, and independent replication is thin. Treat findings as preliminary and cite primary sources directly.
Common questions about bioregulators
What is the shortest peptide in this catalogue?
Vilon, a dipeptide of lysine and glutamate. Solubility, stability and transport all behave differently at that length, so do not carry handling assumptions over from the larger compounds.
Does Epithalon have a certificate like the others?
Yes. Every lot in this category is tested for identity, purity and endotoxin, and the certificate is published before the vial is listed.
Are these for human use?
No. Sold for in-vitro laboratory research only.
Every product in this category is sold for in-vitro laboratory research only and is not for human or animal consumption, diagnostic or therapeutic use.
