TB-500 (Thymosin Beta-4, Thymosin Beta-4) is a natural peptideA peptide is a molecule consisting of a chain of amino acids linked together by peptide bonds. Peptides are shorter chains than proteins and usually contain from 2 to 50 amino acids. When the number of amino acids in a chain exceeds 50, such molecules are called proteins. Peptides can perform various functions in the body, including: Hormones, Neuropeptides, Antibiotics, Antioxidants consisting of 43 amino acidsAmino acids are the fundamental building blocks of proteins and play a key role in biological processes. There are a total of 22 standard amino acids used for protein synthesis in living organisms. that plays an important role in regulating cellular processes such as tissue healing, angiogenesis (the formation of new blood vessels), and reducing inflammation. TB-500 is a synthetic version of thymosin beta-4, which is produced in the thymus (thymus gland) and other tissues in the human body. This peptide has attracted attention for its regenerative and anti-inflammatory properties, making it potentially useful for treating injuries and speeding recovery.
TB-500 and Thymosin Beta-4 (Tß4) are essentially the same thing. TB-500 is a synthetic version of the natural peptide Thymosin Beta— 4, which consists of 43 amino acids.
Basic properties of TB-500

Actin Activation:
TB-500 binds to actin, a protein that plays an important role in cell structure and movement. This promotes cell migration to the site of injury and accelerates healing.
Stimulation of angiogenesis:
The peptide increases the production of VEGF (vascular endothelial growth factor), which leads to the formation of new blood vessels and improves blood supply to tissues.
Suppressing inflammation:
TB-500 modulates the immune response by reducing the level of pro-inflammatory cytokines such as IL-1β and TNF-α.
Acceleration of cell proliferation:
The peptide stimulates cell division and growth, which is important for repairing damaged tissues.
TB-500 Application
TB-500 is being investigated primarily in preclinical and clinical studies, but its potential applications include:
Sports medicine:

Ophthalmology:
TB-500 may be useful for treating damage to the cornea and other eye tissues.
Application forms
TB-500 is usually given as an injection (subcutaneous or intramuscular). It can be entered:
Locally: in the area of damage to accelerate healing.
Systemically: for general effects on the body.
Safety and side effects
TB-500 is considered relatively safe, and no serious side effects have been identified in animal studies. However, as with other peptides, the long-term safety and efficacy of TB-500 in humans require further investigation. Possible side effects may include:
Slight irritation at the injection site.
Allergic reactions (rare).
Difference between TB-500 and BPC-157
Although both peptides have regenerative and anti-inflammatory properties, they have different mechanisms of action and applications:
TB-500: More focused on improving tissue flexibility, angiogenesis, and systemic recovery.
BPC-157: more commonly used for gastrointestinal healing and local tissue repair.
Conclusion
TB-500 is a promising peptide with a wide range of potential therapeutic applications, especially in the areas of tissue regeneration, reducing inflammation, and accelerating recovery from injuries. However, despite the positive results of preclinical studies, additional clinical trials are needed to confirm its effectiveness and safety in humans.
Why is TB-500 considered for the treatment of liver fibrosis?
TB-500 has several properties that make it potentially useful for treating liver fibrosis:
Antifibrotic effect:
TB-500 suppresses the activity of TGF-β (transforming growth factor beta), which is a key mediator of fibrosis. TGF-β stimulates the activation of liver stellate cells, which produce excess collagenCollagen is a fibrillar protein, one of the main building elements of the body. It constitutes a significant part of connective tissues such as skin, tendons, joints, bones, and cartilage. Collagen provides strength, elasticity, and structural integrity to these tissues, giving them the ability to resist stretching. and other components of the extracellular matrixThe extracellular matrix is a multicomponent complex of structural molecules that maintain the structural integrity of tissues. It provides an organized environment within which cells of various tissues move and interact. It binds cells into a single system, ensures the preservation and dissemination of information. It is a gel, the most important component of which is hyaluronic acid, which stimulates cell migration, has a unique ability to bind water, maintains the skin's water balance, determining its firmness and elasticity..
The peptide also promotes the degradation of fibrous tissue by activating matrix metalloproteinases (MMPs), which break down excess collagen.
Anti-inflammatory effect:
TB-500 reduces levels of pro-inflammatory cytokines such as TNF-α and IL-1β, which helps reduce inflammation and prevent further liver damage.
Stimulating regeneration:
The peptide promotes the restoration of hepatocytesHepatocytes are the main cells of the liver. They account for 60 to 80% of the mass of the entire organ. These are the main functional units of the liver, involved in a wide range of physiological processes such as nutrient metabolism, protein synthesis, detoxification, and bile secretion. (liver cells) and improves blood supply by stimulating angiogenesis (the formation of new blood vessels).
Protecting cells from apoptosis:
TB-500 increases the survival rate of hepatocytes, preventing their death under stress conditions, such as toxic or ischemic damage.
Animal studies:
Preclinical studies in animal models of liver fibrosis have shown that TB-500:
Reduces the severity of fibrosis.
Reduces the level of collagen and other components of the extracellular matrix.
Improves liver function.
These results are encouraging, but it is important to understand that animal data is not always directly applicable to humans.
Human clinical trials:
Currently, clinical trials of TB-500 for the treatment of liver fibrosis in humans are in the early stages. There is not yet sufficient evidence to suggest that the peptide can be an effective and safe treatment for human liver fibrosis. However, the preliminary results are encouraging, and research is ongoing.
Important aspects:
Stage of fibrosis:
In the early stages of fibrosis (F1-F2 on the METAVIR scale), TB-500 may be more effective, since the process is still reversible.
In the advanced stages (F3-F4, cirrhosis), complete reversal of fibrosis is unlikely, but TB-500 can slow the progression of the disease and improve liver function.
Integrated approach:
Treatment of liver fibrosis should be comprehensive and include not only TB-500, but also other methods, such as:
Eliminating the cause of fibrosis (for example, treating viral hepatitis, avoiding alcohol).
The use of antifibrotic drugs (for example, pentoxifylline, silymarin).
Maintaining a healthy lifestyle (diet, physical activity).
Safety:
Although TB-500 is considered relatively safe, its long-term effects and possible side effects in humans are not fully understood.
Conclusion:
TB-500 (Thymosin Beta-4) has significant potential for the treatment of liver fibrosis due to its antifibrotic, anti-inflammatory and regenerative properties. However, its use for this purpose is still experimental, and additional clinical studies are needed to confirm its effectiveness and safety in humans.
