The standard TB-500 dosage per week for tissue repair after injury is 2.5 mg to 5 mg, split into two injections, for the first 4 to 6 weeks, followed by a maintenance dose of 2.5 mg once per week. This dosing protocol aligns with the natural stages of tissue repair, supporting inflammation modulation, cell migration, and new blood vessel formation. TB-500, a synthetic fragment of thymosin beta-4, accelerates healing by regulating actin, a protein essential for cell movement and structure.
How TB-500 Works in Tissue Repair Stages
Tissue repair unfolds in three overlapping stages: inflammation, proliferation, and remodeling. TB-500 influences each phase through distinct mechanisms. During the initial inflammatory stage, which lasts up to 72 hours post-injury, the peptide reduces excessive swelling and recruits immune cells to clear debris. In the proliferation stage, spanning days 3 to 21, TB-500 promotes angiogenesis, the formation of new blood vessels, and stimulates fibroblast migration to lay down collagen. Finally, in the remodeling stage, from day 21 onward, it helps organize collagen fibers and restore tissue strength.
Inflammation Stage and TB-500 Dosing
In the first few days after injury, inflammation is necessary but can become chronic if unregulated. TB-500 dosing during this stage typically starts at 2.5 mg twice a week. This initial TB-500 dosage per week helps modulate the inflammatory response by downregulating pro-inflammatory cytokines like TNF-alpha and upregulating anti-inflammatory signals. Animal studies show that thymosin beta-4 reduces neutrophil infiltration and speeds the transition to the next healing phase. For acute injuries, beginning TB-500 within 24 to 48 hours may yield the best results.
Proliferation Stage and Optimal TB-500 Dosage
As the injury moves into the proliferation stage, TB-500 dosage per week remains at 5 mg total, split into two 2.5 mg doses. This stage requires robust cell proliferation and matrix deposition. TB-500 upregulates vascular endothelial growth factor (VEGF), driving new capillary formation to deliver oxygen and nutrients. It also enhances keratinocyte and fibroblast migration, critical for wound closure. A consistent TB-500 dosing schedule ensures sustained peptide levels to support these processes. Some protocols extend the 5 mg weekly dose for up to 8 weeks for severe injuries.
Remodeling Stage and Maintenance Dosing
During the remodeling stage, which can last months, TB-500 dosage per week is often reduced to 2.5 mg once weekly. This maintenance dose continues to support collagen remodeling and prevents excessive scar formation. TB-500 influences matrix metalloproteinases, enzymes that remodel the extracellular matrix, leading to stronger, more organized tissue. For chronic injuries or slow-healing tissues like tendons and ligaments, a longer maintenance phase of 2 to 3 months may be beneficial. Always consult a healthcare provider before adjusting your peptide regimen.
TB-500 Dosage Per Week: Detailed Protocol
For most soft tissue injuries, the recommended TB-500 dosage per week is 5 mg, administered as two 2.5 mg injections every 3 to 4 days. This dosing frequency maintains stable blood levels due to the peptide's half-life of approximately 2 to 3 days. Here is a week-by-week breakdown for a typical 6-week cycle:
- Weeks 1-4: 5 mg per week (2.5 mg twice weekly)
- Weeks 5-6: 2.5 mg per week (once weekly)
- Maintenance (optional): 2.5 mg every 10-14 days for ongoing support
This TB-500 dosing protocol can be adjusted based on injury severity. For minor strains, a lower total weekly dose of 2.5 mg may suffice. For major tears or post-surgical recovery, some users extend the 5 mg weekly dose for 8 weeks before tapering. Always start with the lowest effective dose to assess tolerance.
How to Reconstitute and Inject TB-500
TB-500 typically comes as a lyophilized powder in 5 mg vials. To reconstitute, add 1-2 mL of bacteriostatic water to the vial, gently swirl until dissolved, and store in the refrigerator. A common concentration is 5 mg/mL. For a 2.5 mg dose, draw 0.5 mL into an insulin syringe. Inject subcutaneously into fatty tissue, such as the abdomen or thigh, rotating sites to prevent irritation. Always use sterile techniques to avoid contamination.
TB-500 Dosing for Specific Injuries
Different injuries may respond to tailored TB-500 dosing. For muscle tears, a 5 mg weekly dose for 4-6 weeks is standard. Tendon and ligament injuries, which heal slowly due to poor blood supply, often require a longer cycle of 6-8 weeks at 5 mg per week, followed by 4 weeks of maintenance. For bone fractures, preliminary research suggests TB-500 may enhance callus formation, but human data is limited. In such cases, a 5 mg weekly dose for 8-12 weeks is sometimes used. Combining TB-500 with other peptides like BPC-157 may yield synergistic effects, though this should be approached cautiously.
Scientific Evidence Supporting TB-500 Dosage
Multiple animal studies inform current TB-500 dosage per week recommendations. In a rat model of myocardial infarction, thymosin beta-4 at 5 mg/kg improved cardiac function and reduced scar size. While human doses are lower, the principle of frequent dosing aligns with the peptide's short half-life. A study on dermal wounds in mice showed that thymosin beta-4 accelerated closure by 40% when administered daily. For musculoskeletal injuries, research indicates that systemic administration promotes tendon and ligament healing. These findings support a TB-500 dosing schedule that maintains therapeutic levels throughout the repair stages.
Potential Side Effects and Safety Considerations
TB-500 is generally well-tolerated, but some users report mild side effects such as fatigue, headache, or injection site reactions. These typically resolve quickly. Because TB-500 promotes angiogenesis, there is a theoretical risk of accelerating cancer growth, though no human studies confirm this. Individuals with active cancer should avoid TB-500. Long-term safety data is lacking, so cycling the peptide with breaks is advisable. Always purchase from reputable sources to ensure purity and avoid contaminants.
TB-500 vs Other Healing Peptides
TB-500 is often compared to BPC-157, another popular healing peptide. While both support tissue repair, TB-500 excels in systemic effects and angiogenesis, making it ideal for widespread or deep injuries. BPC-157 is more localized, particularly effective for gut and tendon healing. Some protocols combine them for comprehensive recovery. For aging-related repair, peptides like GHK-Cu may complement TB-500 by enhancing collagen synthesis.

Where to Buy TB-500 Online
When looking to buy TB-500, choose vendors that provide third-party purity testing and clear product information. Research peptide suppliers often sell TB-500 in 5 mg vials, with prices ranging from $30 to $60 per vial. Always verify the legal status in your country, as regulations vary. For tissue repair purposes, ensure the product is labeled for research use only. Avoid suppliers with unrealistic claims or missing contact information.
Maximizing Results with TB-500 Dosing
To optimize TB-500 dosage per week, combine it with proper nutrition, hydration, and physical therapy. Protein intake supports collagen synthesis, while vitamin C and zinc are cofactors for tissue repair. Avoid anti-inflammatory drugs like NSAIDs during the early stages, as they may blunt the healing response. Gentle movement and progressive loading, guided by a professional, can enhance remodeling. For older adults, peptides like MOTS-c may address mitochondrial decline that impairs healing. Learn more in our comparison of GHK-Cu vs MOTS-c for anti-aging after 50.
