Khavinson Peptide Bioregulators: A Complete List of All Types and What They Are

By Bryan Rider | Rebel Peptides

Ask 10 peptide brands which Khavinson bioregulator targets the kidney. You will get 4 different answers. That is not a research problem. That is a marketing problem.

The Khavinson framework has been around for 50 years. The list of bioregulators is fixed. The naming is documented. And yet every supplement site selling these products tells a different story about what is what.

So I am fixing that here. This is the complete list of Khavinson peptide bioregulators by category, by A-number, and by tissue source. No mystery names. No marketing fluff. Just the facts of what each one is, where it comes from, and how it fits into the bigger picture.

If you are new to the category, start with The Complete Beginner's Guide to Peptide Bioregulators first. That covers the science. This blog is the reference list.

What Khavinson Peptide Bioregulators Are

Khavinson peptide bioregulators are short chains of amino acids developed at the St. Petersburg Institute of Bioregulation and Gerontology. Each one targets a specific tissue. Each one is built from peptide extracts that the research links to gene expression and protein biosynthesis in that tissue.

The framework comes from over 50 years of work by Professor Vladimir Khavinson and the Saint Petersburg Institute team. Their research focused on how small peptides influence biological processes inside cells, including protein synthesis, cell division, and tissue repair.

The Petersburg Institute of Bioregulation work covered both animal studies and human trials over several decades. Independent replication in other countries followed. The International Association on Aging picked up parts of the framework into the European Region of medical service literature.

The category we now call peptide bioregulation came directly out of this research.

The Two Types: Natural and Cytogens

Khavinson peptide bioregulators come in two formats. Both come from the same research framework. The difference is how they are made.

Natural peptide bioregulators (Cytomaxes) are extracted from young animal tissue. The full peptide complex stays intact. These are the originals. Most use peptide extracts from the cerebral cortex, thymus, liver, kidney, or other specific organs depending on the target.

Synthetic bioregulators (Cytogens) are built in a lab. The amino acid sequence is reproduced one piece at a time. These short peptides match the structure of the natural versions.

Same research foundation. Different production method. We carry both lines.

The Master List by Organ System

Each Khavinson peptide bioregulator targets a specific tissue. The A-number is the official research designation. The brand name is how it is sold.

Brain and Nervous System

Cerluten is the original cerebral cortex peptide bioregulator and one of the most studied in the Khavinson research, particularly around cognitive function. Endoluten is the pineal peptide bioregulator. The pineal gland is one of the most-researched organs in the Khavinson framework because of its connection to melatonin production and circadian rhythm.

Immune System

The thymus is the master organ of the immune system. It undergoes gradual involution with age, meaning it shrinks and produces fewer immune cells. Thymic peptides are the most-studied category in the immune side of the Khavinson framework. Vladonix is the thymus peptide bioregulator most associated with the original 6-year Khavinson study on immune function markers.

Cardiovascular System

Ventfort and Chelohart appear together in cardiovascular protocols. Ventfort focuses on blood vessels. Chelohart focuses on heart muscle tissue.

Digestive System

Suprefort is the pancreas peptide bioregulator. Svetinorm targets the liver. Stamakort handles gastric tissue.

Endocrine System

The endocrine system handles hormone balance through interconnected glands. Thyreogen handles thyroid tissue. Glandokort handles adrenal. Bonothyrk handles parathyroid.

Urinary System

Pielotax is the kidney peptide bioregulator. Chitomur is the bladder version. Both appear in the urinary protocol from the original Khavinson research.

Male Reproductive System

Testoluten is the testes peptide bioregulator. Libidon is the prostate version. These two appear together in the male reproductive system protocol.

Female Reproductive System

Zhenoluten is the ovary peptide bioregulator. It appears with Thyreogen and Ventfort in the female reproductive protocol. The reproductive period in the Khavinson research is one of the more thoroughly studied lifecycle markers.

Musculoskeletal System

Sigumir is the cartilage and spine peptide bioregulator. Gotratix targets muscle. Bonomarlot covers bone marrow tissue.

Visual System

Visoluten is the retina peptide bioregulator. Often part of visual health protocols alongside Cerluten and Ventfort.

Respiratory System

Taxorest handles bronchial tissue. Part of the original Khavinson respiratory protocol when paired with Vladonix and Ventfort.

You can also use Chonluten, our lung and bronchial mucosa bioregulator: Chonluten.

How to Read This List

Every Khavinson peptide bioregulator is built the same way. Tissue source. A-number. Brand name. Three pieces of information.

When you see a name you do not recognize, look up the A-number first. That tells you the official research designation. Then check the tissue source. That tells you the target organ. The brand name is just the commercial label.

Example: A-9. Kidney tissue. Sold as Pielotax. Same peptide complex sold under other names in other countries, but the A-number and target organ never change.

This is why the Khavinson framework is easier to navigate once you know the system. You stop chasing brand names and start tracking research numbers.

The Research Context: Why This Category Exists

The Khavinson peptide bioregulator framework grew out of a much bigger field. To understand why this category gets so much attention in longevity research, you have to understand the underlying peptide theory.

Khavinson and his team studied how small peptides influence genetic mechanisms inside the cell. Their research described what they called peptide regulation. The idea is that short peptides interact with DNA and histone proteins to affect gene expression. That interaction influences protein biosynthesis, which is the process cells use to build the structural and functional proteins your body needs.

The research also looked at telomere length, telomerase activity, and the cellular processes connected to accelerated aging. Some studies covered telomere elongation and telomerase activation in vitro studies. Other work focused on geroprotective effects, age related diseases, and the gradual decline in protein synthesis seen across the aging process.

This is the gerontological aspects side of the Khavinson research. It is the reason peptide bioregulators are studied in the longevity research field rather than the general supplement field.

A few foundational papers for further reading:

• Khavinson VK et al. (2012). Peptidergic regulation of gene expression

• Khavinson, V.K. (2011). Gerontological Aspects of Genome Peptide Regulation

The research depth is the reason this category exists in the first place. Professor Khavinson has published over 775 papers and holds nearly 200 patents through the Saint Petersburg Institute and the broader peptide bioregulation field.

The Protocol Logic

The original Khavinson research grouped peptide bioregulators into system-level protocols. Each protocol uses 2 to 5 organ-specific bioregulators that share a functional connection.

A few of the most common groupings from the original research:

• Urinary system protocol: A-6 Vladonix, A-12 Chitomur, A-9 Pielotax

• Male reproductive system: A-13 Testoluten, A-16 Libidon, A-17 Glandokort

• Female reproductive system: A-15 Zhenoluten, A-2 Thyreogen, A-3 Ventfort

• Respiratory system: A-6 Vladonix, A-19 Taxorest, A-3 Ventfort

• Intensive physical activity: A-6 Vladonix, A-4 Sigumir, A-3 Ventfort, A-18 Gotratix, A-5 Cerluten

What I Tell People Who Are New

If you are looking at this list for the first time and feeling overwhelmed, here is the simplest path forward.

Start with two foundational peptide bioregulators. The Khavinson framework suggests Vladonix (thymus, A-6) and Endoluten (pineal, A-8) as the two anchors. These are the master regulators that influence everything downstream. Most people start there.

After 30 days, you add the organ-specific peptide bioregulator that matches your top concern. Liver. Joints. Vision. Kidney. Heart. Whatever is most relevant to your goals.

That is how the original Khavinson protocols were designed. Foundational layer first. Specific layer second.

A Note on Regulatory Status

Khavinson peptide bioregulators are sold as dietary supplements. They are not FDA approved as drugs. The research base for the category is significant, with over 50 years of published work, but the supplements themselves are not pharmaceutical products and should not be treated as medicine.

Always consult a qualified healthcare provider before starting any supplement protocol, especially if you take prescription medication or have a diagnosed health condition.

Final Thought

The Khavinson peptide bioregulator system is a 50-year-old research framework. Not a trend. Not a new supplement category. A documented map of organ-specific short chain peptides developed in one of the most rigorous longevity research programs ever conducted.
