TB500

Talk to Us

Thymosin Beta-4 (TB-500) is a naturally occurring peptide made up of 43 amino acids, first discovered in the thymus gland. It belongs to the thymosin family of peptides, which are involved in immune function and cellular growth. TB-500 can be found in various tissues, including the spleen and peritoneal macrophages, where it plays a role in tissue repair and regeneration.

How Does Thymosin Beta-4 Work?

Thymosin Beta-4 works primarily by increasing the production of actin, a protein that is essential for cellular movement, structure, and repair. By promoting actin production, TB-500 supports the regeneration of tissues, speeds up wound healing, and improves overall cellular health.

Potential Benefits of Thymosin Beta-4

1. Wound Healing and Recovery:
   TB-500 is highly regarded for its role in enhancing wound healing, making it a valuable tool for athletes and bodybuilders. It promotes angiogenesis (the formation of new blood vessels), which speeds up tissue repair and recovery after injury .
2. Muscle Growth and Fat Loss:
   By regulating actin and other muscle-building proteins, Thymosin Beta-4 plays a key role in the development of muscle fibers. When used alongside other peptides such as BPC-157 or CJC-1295, it can promote muscle mass growth and help reduce body fat .
3. Improved Stamina and Endurance:
   Thymosin Beta-4 not only assists in recovery but also enhances physical endurance and stamina. Athletes can benefit from faster healing of bruises or injuries, allowing them to maintain training intensity .
4. Corneal Health:
   TB-500 has shown positive effects on eye health, particularly in maintaining the integrity of the cornea. Studies suggest that it can improve healing in the outer layer of the eye .
5. Cardiovascular Recovery:
   After a heart attack or myocardial infarction, Thymosin Beta-4 may aid in faster recovery. Research indicates that it helps repair heart tissue and improve cardiovascular function following such events .

Side Effects of Thymosin Beta-4

Thymosin Beta-4 is generally well-tolerated, but some individuals may experience mild side effects, including:

• Lightheadedness
• Fatigue
• Nausea
• Headache
• Skin irritation at the injection site
• Temporary energy drops

Thymosin Beta-4 Dosage

The recommended dosage for TB-500 varies based on the intended use. For general tissue repair and healing, a typical dose ranges from 2 to 2.5 mg per week, split into smaller daily injections. For eye health, TB-500 eye drops are evaluated across several time points, typically from Day 1 to Day 56 of treatment . For muscle growth, a common dose is between 300 micrograms and 1 gram per day, often taken in cycles of 6 weeks on, followed by 6 weeks off.

Can TB-500 Be Used for Muscle Growth or Performance Enhancement?

Research suggests that TB-500 can enhance muscle hypertrophy, which can lead to increased muscle size and strength. This is likely due to its ability to promote angiogenesis, improving blood flow and nutrient delivery to muscle cells, thereby supporting their growth .

Scientific Findings on Thymosin Beta-4

1. A study on Mdx mice showed that Thymosin Beta-4 increased skeletal muscle regeneration after 6 months of treatment, with enhanced muscle repair observed during exercise-induced muscle damage .
2. Other studies suggest that TB-500 may help repair nerve tissue and aid in recovery from conditions like stroke and myocardial infarction .
3. A 2010 study found that local application of Thymosin Beta-4 improved wound healing, reduced scarring, and enhanced collagen organization .
4. In a clinical trial involving nine participants, eye drops containing Thymosin Beta-4 significantly reduced dry eye symptoms and improved clinical measures of eye health by up to 59% after 56 days of treatment .
5. Another study focusing on venous ulcers, which are difficult to heal, showed that a 0.03% solution of synthetic Thymosin Beta-4 accelerated healing in 25% of patients within three months .

These studies highlight the potential of Thymosin Beta-4 in both medical and athletic settings, underscoring its effectiveness in tissue repair and muscle growth while maintaining a favorable safety profile.
