What it is
Vilon is a synthetic two-amino-acid peptide (lysine-glutamate) belonging to the Khavinson family of short peptide bioregulators, a research group derived from tissue extracts and linked to specific organ systems. It derives from thymic research, placing it alongside compounds like Thymalin in the literature.

What it is
Vilon is a two-amino-acid peptide — lysine and glutamate. It belongs to the Khavinson family of short peptide bioregulators, a group developed in Russia from tissue extracts, where each short peptide is associated with a particular organ system. Vilon derives from thymic work, which is why it is discussed alongside Thymalin.
Research context
Grouped under immune and longevity and anti-aging research. Vilon is discussed in relation to immune regulation and cellular aging, largely in the context of gene-expression and lifespan studies published by the Khavinson group.
The evidence base here differs in kind from most of this library: the great majority of bioregulator research comes from a single research programme and is published in Russian-language journals, with limited independent replication elsewhere. That is a fact about the literature, not a judgement about the compound.
Status
- Regulatory status: Research-only. Not FDA-approved for human use.
- Sport status: Not specifically listed on the WADA Prohibited List.
Reconstitution and handling
Reconstitution follows the standard math: concentration equals the milligrams in the vial divided by the millilitres of bacteriostatic water added. There is no single correct concentration — it depends on solubility and how large a draw is wanted. If a mix does not go fully clear, add more water. The reconstitution calculator shows concentration, draw size and portions per vial for any volume.
Refrigerate reconstituted vials at 2–8 °C, keep them out of light, wipe stoppers with alcohol before each puncture, and label with the mix date. Discard anything cloudy, discoloured, or with floaters.
Status in sport
Vilon is not named on the WADA Prohibited List. Verify against the current year’s list, since classification can change.

Frequently asked questions
What is a Khavinson bioregulator?
A family of very short synthetic peptides, typically two to four amino acids, developed in Russia from tissue extracts. Each is associated with a particular organ system; Vilon comes from thymic research.
How strong is the evidence for Vilon?
Most of it comes from a single research programme and is published in Russian-language journals, with limited independent replication. That is worth knowing when comparing it to compounds with broader international literatures.
How does Vilon relate to Thymalin?
Both come from thymic research within the same bioregulator programme. Thymalin is a peptide extract preparation; Vilon is a defined synthetic dipeptide.
What the research community gets wrong about Vilon
- A short sequence is not a simple story. Being a dipeptide says nothing about how well characterised a compound is. Vilon’s literature is narrow and concentrated in one research programme.
- Vendor labels are not assays. Identity and purity come from a certificate of analysis on the batch in front of you, not from the name printed on a vial.
- A reconstituted vial does not stay good forever. Compounds in solution break down over time, and rough handling (shaking hard enough to foam) can damage them. Note the reconstitution date and store as your protocol calls for.
