Thymosin beta-4 is a natural peptide composed of 43 amino acids that is present in almost all human and animal tissues. It belongs to the thymosin peptide family and has been described in research models as having a role in cell migration, angiogenesis, inflammatory response and repair processes. The synthetic version of this peptide is more widely known as TB-500. Thymosin Beta-4 is particularly active in areas of tissue damage, where it stimulates cell regeneration and the formation of new blood vessels. These properties are the reason Thymosin Beta-4 is a subject of research interest in orthopedics, cardiology, dermatology and sports medicine.
Thymosin Beta-4 is being studied for its possible effects on:
Healing of muscle and tendon injuries – in research models, an effect on repair processes and tissue regeneration has been observed.
Stimulation of angiogenesis – a described effect on the formation of new capillaries and local blood supply.
Anti-inflammatory effect – observed influence on inflammatory mediators and local edema.
Joint and bone health – described effect on recovery processes after joint and bone injuries.
Healing of skin and connective tissue lesions – in research settings, an effect on the healing of wounds and surgical incisions has been observed.
Improved recovery in athletes – faster recovery after exercise has been described in experimental models.
Neuroprotective potential – observed role in the regeneration of peripheral nerves and limitation of neurotoxic damage.
Thymosin Beta-4 has been extensively studied in preclinical settings and in limited clinical trials.
Effects on tendon and muscle damage repair, as well as osteogenesis and inflammatory processes in joints, have been described in orthopedic research models.
In cardiological research models, a protective effect on ischemic myocardial damage has been observed, associated with angiogenesis and improved local blood supply.
In dermatological and plastic surgery studies, an effect on the healing of chronic skin wounds, ulcers and surgical scars has been described.
In neurological research models, a potential effect on nerve cell protection and axon regeneration has been observed.
In the scientific literature, subcutaneous administration of doses of 2-5 mg, administered 3 times a week for 4-6 weeks, is most commonly found, followed by a maintenance phase.
At 5 mg + 3 ml bacteriostatic water: 1.67 mg/ml → 0.15 ml = 0.25 mg= 250μg
Example values for 5 mg:
0.15 ml = 250μg
0.3 ml = 500μg
0.45 ml = 750μg
0.6 ml = 1 mg
0.75 ml = 1.25 mg
Thymosin Beta-4 is banned by WADA for use in professional sports because it can:
accelerate recovery after muscle and tendon injuries
improve blood supply and tissue healing
reduce recovery time between heavy loads
increase endurance by optimizing local circulation
In research settings, rare and mild reactions have been described such as:
fatigue
headache
dizziness
redness or pain at the injection site
Less commonly, changes in appetite, drowsiness, or mild fluid retention may occur.
