What Are Peptide Bioregulators?
Peptide bioregulators are a class of very short peptides, most only two to four amino acids in length, that emerged from the research program of Russian scientist Vladimir Khavinson and colleagues. Because of their compact structure, these molecules are frequently studied as model compounds for investigating how minimal peptide sequences may interact with cellular and genetic machinery in laboratory systems.
The central hypothesis explored in the preclinical literature is that certain short peptides display a degree of tissue specificity, with individual sequences investigated in the context of particular organ systems. Researchers have organized these compounds into a conceptual framework in which each peptide is paired with a target tissue of interest, from the thymus and pineal gland to the liver, heart, and reproductive organs.
This pillar guide introduces the peptide bioregulator class for laboratory professionals and outlines how each compound is typically framed in research settings. Every product referenced is supplied by Amino Labs at 99%+ HPLC purity in lyophilized form, third-party tested, and offered strictly for research use only.

The Seven Khavinson Peptides and Their Research Framing
Each short peptide bioregulator is associated in the literature with a specific tissue or biological process. The following compounds are commonly studied within this framework:
- Testagen (20mg) - investigated in research models concerning reproductive and testicular tissue and associated peptide signalling.
- Ovagen (20mg) - studied in the context of hepatic tissue and protein-synthesis pathways in preclinical settings.
- Livagen (20mg) - explored as a liver-associated bioregulator alongside chromatin and gene-expression research questions.
- Cardiogen (20mg) - examined in models relating to cardiac and myocardial tissue.
- Thymalin (10mg) - one of the most extensively studied peptides in this group, investigated in relation to thymus and immune-system research.
- Pinealon (10mg) - studied within neurological and pineal-associated research contexts.
- Epithalon (50mg) - perhaps the best known of the class, investigated in telomere-biology and pineal-related research models.
It is important to frame these associations correctly: the tissue pairings reflect how compounds are grouped and studied in the preclinical literature, not established outcomes in humans. Researchers designing studies typically treat each peptide as a discrete reagent and evaluate purity, solubility, and stability before use. Because the sequences are short, HPLC verification of identity and purity is a routine part of characterization when working with these compounds in the laboratory.
Handling, Storage, and Quality Considerations
Short peptide bioregulators are supplied by Amino Labs as lyophilized powder to maximize stability during shipping and storage. As a general laboratory practice, lyophilized peptides are stored desiccated and protected from light, with long-term storage typically at low temperature. Once reconstituted for research, short peptides are generally more stable than larger sequences but are still handled as time-sensitive reagents.
Every compound in this class from Amino Labs is characterized to 99%+ HPLC purity and third-party tested, which matters especially for very short peptides where trace impurities or incomplete sequences can complicate interpretation of experimental data. As a Canadian-owned supplier shipping across Canada, Amino Labs provides these reagents strictly for controlled laboratory settings.
Researchers new to the class often begin with the most widely characterized members, such as Epithalon and Thymalin, before expanding to organ-specific compounds. Consistent lot quality and verified purity support reproducibility across experimental replicates.
