Researchers in UK laboratories investigating bioregulator peptides typically focus on gene expression, cellular signalling, and tissue-specific regulation, with particular interest in models of cellular ageing and age-related decline. At River Peptides, this category covers short-chain research compounds intended for laboratory and in vitro use only, not for human or veterinary use.

Every batch listed in this category carries a purity result of over 99%, and River Peptides operates under ISO 9001 (quality management) and ISO 14001 (environmental management) accreditation, which governs how that testing is carried out and recorded.

Why Choose Us for Bioregulator Peptides?

This category is built around Cartalax, Bronchogen, Epitalon, and Pinealon, together with other bioregulators including Vesugen, Livagen, and Ovagen.

Each batch goes through independent testing before it’s listed for sale. Two third-party laboratories carry this out: Janoshik Laboratories in the Czech Republic and Analiza Biatek in Poland, using High Performance Liquid Chromatography and mass spectrometry, laboratory techniques that separate a sample into its component molecules and confirm exactly what they are, to check purity and compound identity.Ā 

The resulting certificate of analysis is published against the batch ID printed on the product label, so a researcher can look up the specific data for the exact batch they’ve received.

River Peptides also holds ISO 9001 and ISO 14001 accreditation, covering quality management and environmental management respectively. These are mentioned because they’re accreditations River Peptides actually holds and can document on request, not as a suggestion that no other supplier holds them. More detail on how the testing process works sits on our independent testing page.

Product listings in this category carry the supporting technical information researchers typically need before ordering: molecular weight, amino acid sequencing (the exact order of the amino acid building blocks that make up the peptide), storage requirements, reconstitution instructions, and how to safely mix the freeze-dried powder with a liquid before use.

Individual researchers can order directly, and organisations with an approved trade account can do the same, across the UK.

Peptides Studied for Longevity and Age-Related Research

Within the broader bioregulator category, a smaller set of compounds is specifically associated with ageing and longevity research rather than cellular signalling more generally. Epitalon and Cartalax are the two most frequently referenced examples in this narrower area of study.

Research on Epitalon has centred on its effect on telomerase activity in cultured human cells. Telomerase is the enzyme that rebuilds telomeres, the protective caps on the ends of chromosomes that shorten a little each time a cell divides.Ā 

Khavinson, Bondarev, and Butyugov (2003), writing in the Bulletin of Experimental Biology and Medicine, reported that Epitalon triggered telomerase expression and telomere elongation in human fetal fibroblasts, cells taken from connective tissue, that had previously stopped producing the enzyme (Khavinson et al., 2003). The finding is limited to cell culture, cells grown in a lab dish rather than in a living organism, and doesn’t extend to a human trial.

Cartalax, also known as T-31 or AED, has been studied directly in a small number of preclinical models, laboratory and animal studies carried out before any human testing. Chalisova and colleagues (2015), writing in the Bulletin of Experimental Biology and Medicine, found that T-31 stimulated cell proliferation, meaning cell division and growth, and reduced apoptosis, the process of programmed cell death, in kidney tissue cultures taken from young and old rats. This effect was weaker than that of the full polypeptide extract T-31 was derived from, a larger, naturally occurring peptide taken from the same tissue (Chalisova et al., 2015). This is a kidney tissue model, not a cartilage or joint model, and the cartilage-focused claims sometimes made about Cartalax elsewhere aren’t backed by comparably direct evidence, so this page doesn’t repeat them.

Current research within this category commonly covers:

  • Cellular ageing markers: telomerase activity, telomere length, and cell senescence, the point at which a cell stops dividing but doesn’t die off.
  • Tissue-specific gene expression: organ- or tissue-targeted regulatory activity, including kidney, bone, and glandular tissue.
  • Systemic and neuroprotective effects: broader stress response and circadian regulation, the body’s internal day-night clock that governs sleep and hormone cycles.

Peptides occasionally discussed alongside bioregulators are listed under different categories on this site. Tesamorelin, studied for its effect on the growth hormone axis, the pathway connecting the brain and pituitary gland that controls natural growth hormone release, sits within our Growth Hormone category.Ā 

Selank and Semax, associated with cognitive and nootropic research (meaning research into possible effects on focus and mental performance) are listed in our Cognitive & Nootropics category.

Frequently Asked Questions

Are bioregulator peptides legal to buy in the UK for research?

Yes. The compounds listed in this category are sold for research use and are legal to purchase in the UK on that basis. None of them are licensed medicines, none have approval for human use from the MHRA, the UK's Medicines and Healthcare products Regulatory Agency, or the FDA, its US equivalent, and none are intended for human consumption.

A bioregulator peptide is a short chain of amino acids, typically 2 to 4 in length, studied for its ability to enter the cell nucleus and interact directly with gene expression, the process of switching specific genes on or off, in a tissue-specific way. This is shorter than most general research peptides, which usually work by binding to receptors on the outside of a cell rather than acting on DNA directly.

The concept was developed by Vladimir Khavinson, a Russian gerontologist whose peptide bioregulator research began in the 1970s at the Kirov Military Medical Academy.Ā 

He founded the Saint Petersburg Institute of Bioregulation and Gerontology in 1992 and directed it until his death in January 2024. His research group identified short amino acid sequences associated with specific organs and tissues, and used these to develop the synthetic peptides now sold under names such as Epitalon and Cartalax.

Yes. Khavinson peptides is the name commonly used for the same class of compounds, since Vladimir Khavinson's research programme originated the concept. River Peptides uses "bioregulator peptides" as the primary term on this site, but the two names refer to the same underlying research area.

No. The bioregulator peptides sold in this category are supplied as research compounds for laboratory and in vitro use, not as a consumer product. Some other retailers sell bioregulator-derived ingredients as oral food supplements, which sit in a different product category with different manufacturing standards and regulatory requirements. River Peptides does not sell food supplements.

Bioregulator peptides are commonly studied in scientific environments focused on gene expression, cellular communication, and tissue research, an area broadly grouped under the term bioregulation. Research laboratories frequently investigate these compounds in studies related to healthy ageing models, metabolic function, recovery pathways, and peptide signalling more broadly.

There are many types of bioregulators, with those currently studied at River Peptides including:

While classified otherwise on this site, these peptides are also studied as bioregulators:

Peptides, on the other hand, act more as messengers, helping to direct biological processes like tissue repair and hormone production.

None of the compounds in this category have been tested in human clinical trials for the effects sometimes attributed to them online.Ā 

Some, including Epitalon, have shown specific effects in preclinical or cell-culture research (Khavinson et al., 2003), but those results don't establish that the same effect occurs in a living organism or in humans. None of these peptides are licensed or sold as treatments.

Research into bioregulator peptides has explored several potential functions, though most findings remain preclinical or in vitro, meaning they come from laboratory and cell-culture studies rather than human trials. Studied areas include:

  • Inflammatory signalling: Interaction with cytokine and immune-response pathways, the chemical messengers the immune system uses to start or calm down inflammation.
  • Hormonal signalling: Regulation of endocrine and neuroendocrine axes, the hormone systems that connect the brain to glands such as the thyroid and adrenal glands.
  • Oxidative stress response: Protection of cells and tissue from oxidative damage in laboratory models, the wear and tear caused by unstable molecules called free radicals, which naturally build up with age.
  • Cellular energy metabolism: Effects on mitochondrial activity in cell culture, mitochondria being the structures inside cells that generate energy.
  • Tissue-specific regeneration: Gene expression changes linked to tissue repair in specific organ models, meaning changes in which genes are switched on or off within a particular organ's cells.

Bioregulator peptides are a narrower category within the broader peptide research field. General research peptides typically act as messengers, binding to receptors on the outside of a cell to influence processes such as tissue repair or hormone release. Bioregulator peptides are usually shorter and penetrate the cell membrane directly, interacting with the nucleus and DNA rather than an external receptor.
