Manufacturer: XT Labs USA
Active Substance: Thymosin Beta-4 (TB-500)
Pack Size: 1 Vial × 10 mg
Form: Injectable Peptide (for research use only)
TB-500, also known as Thymosin Beta-4, is a synthetic peptide analogue derived from a naturally occurring protein found in nearly all human and animal cells.
It plays an important role in cell regeneration, tissue repair, and inflammation control, making it a key compound in studies related to healing and recovery.
TB-500 is the laboratory-produced version of the natural peptide, allowing for consistent purity and concentration for research purposes.
The primary biological function of Thymosin Beta-4 is to regulate actin, a protein essential for cell movement and structure. By influencing actin production and organization, TB-500 enhances cell migration — a process critical for wound healing and tissue regeneration.
In simple terms, TB-500 helps the body accelerate its natural repair mechanisms by:
Stimulating the formation of new blood vessels (angiogenesis).
Promoting the growth of new cells and tissues in damaged areas.
Reducing inflammation and scar tissue buildup.
These mechanisms collectively help restore normal tissue function and accelerate recovery from injury or strain.
TB-500 has gained recognition for its potential anti-inflammatory and regenerative properties.
While primarily used for research purposes, it is often explored for its possible applications in the following areas:
Promotes repair of damaged muscles, tendons, and ligaments.
Enhances tissue regeneration at the cellular level.
Supports faster healing after injuries or intense physical stress.
Possesses anti-inflammatory effects, helping to manage chronic pain or swelling in affected areas.
May support recovery from overuse injuries or joint discomfort.
Improves joint function by strengthening connective tissues.
May enhance range of motion and reduce stiffness through better tissue elasticity.
Used in sports and fitness contexts for its muscle recovery and injury-prevention potential.
Aids in reducing training downtime and improving resilience after heavy workouts.
In athletic and bodybuilding communities, TB-500 is valued not as a performance enhancer, but as a recovery and injury-prevention compound.
Its potential ability to repair micro-tears and reduce inflammation allows for faster turnaround between training sessions.
Supports recovery from muscle strain or joint stress.
Reduces post-training soreness and inflammation.
Enhances mobility and flexibility for long-term performance.
Encourages faster healing after intensive training cycles.
Important: TB-500 is not a performance-enhancing drug. Its potential use lies in recovery, tissue repair, and injury management support.
| Function | Mechanism | Possible Outcome |
|---|---|---|
| Tissue Repair | Stimulates cell migration and angiogenesis | Faster healing of soft tissues |
| Inflammation Control | Modulates cytokine production | Reduced inflammation and pain |
| Regeneration | Promotes actin synthesis | Enhanced cellular regeneration |
| Flexibility | Improves collagen alignment | Better joint mobility and movement |
| Blood Flow Support | Encourages new capillary formation | Improved oxygen and nutrient delivery |
Certain individuals should avoid TB-500 due to potential risks or contraindications.
Pregnant or breastfeeding women (lack of clinical data)
Cancer patients, as it may promote unwanted cell growth
Individuals with autoimmune disorders or chronic heart/kidney disease
Those with known peptide allergies or sensitivities
Always consult a qualified physician before using or handling any peptide compound.
TB-500 is generally considered well-tolerated in short-term studies, but side effects can occur depending on dosage, injection technique, and individual response.
Temporary fatigue or mild dizziness
Localized irritation or redness at injection site
Nausea or upset stomach (rare)
Headache or mild joint discomfort
Because TB-500 promotes cellular regeneration, it may also aggravate pre-existing tumors or abnormal cell growth — which is why it is contraindicated in cancer patients.
Not FDA Approved:
TB-500 is not approved for human use and is sold strictly for research purposes only.
Consultation Required:
Individuals should consult a licensed healthcare provider before considering any peptide for therapeutic or experimental use.
Storage:
Store in a cool, dry environment (2–8°C).
Keep away from direct sunlight and moisture.
Reconstituted peptide should be refrigerated and used within recommended timeframes.
Medical Monitoring:
Periodic medical supervision, including blood tests, is essential to assess any adverse reactions or systemic effects.
TB-500 is not an FDA-approved drug, supplement, or medical therapy. It is intended for laboratory research use only.
