For tissue repair, a typical TB-500 dosage is 2.0 to 2.5 mg per week, split into two injections, with adjustments based on body weight. A simple calculator multiplies your weight in kilograms by 0.029 to 0.036 mg to get the weekly total. This range comes from clinical research and user reports, balancing efficacy with safety. TB-500, a synthetic fragment of thymosin beta-4, accelerates healing by promoting cell migration and blood vessel formation. Understanding the right dose is critical to avoid underdosing or wasting the peptide.
How TB-500 Works for Tissue Repair
TB-500 is the active region of thymosin beta-4, a protein that regulates actin. Actin is a building block of cell structure and movement. By binding actin, TB-500 helps cells migrate to injury sites. It also stimulates angiogenesis, the growth of new blood vessels. This improves oxygen and nutrient delivery to damaged tissues. In addition, TB-500 reduces inflammation and prevents cell death. These actions make it a powerful tool for healing tendons, ligaments, muscles, and even skin. Unlike growth hormone peptides, TB-500 works locally and systemically without directly raising IGF-1 levels. Its effects are dose-dependent, so precise calculation matters.
TB-500 Dosage Calculator Based on Weight
The most reliable way to find your weekly TB-500 dose is a weight-based formula. Research on thymosin beta-4 in animals and limited human data suggest a dose of 0.029 to 0.036 mg per kilogram of body weight per week. Multiply your weight in kilograms by 0.029 for a conservative dose, or by 0.036 for a more aggressive approach. For example, a 70 kg person would take 2.03 mg per week on the low end and 2.52 mg on the high end. This weekly total is then split into two injections, typically every three to four days. A TB-500 dosage calculator simplifies this: enter your weight, and it outputs the weekly mg. The formula is: Weekly dose (mg) = body weight (kg) x 0.029 to 0.036. Always round to the nearest 0.1 mg for practical measuring.
Standard Weekly TB-500 Dosage Ranges
Most users follow a flat dosing protocol of 2.0 to 2.5 mg per week, regardless of weight. This range works for many because it approximates the weight-based calculation for average-sized adults. A 68 kg individual gets 2.0 mg at the low multiplier. A 75 kg individual gets 2.5 mg at the high multiplier. If you weigh significantly more or less, adjust accordingly. For a 90 kg person, the calculated range is 2.6 to 3.2 mg per week. For a 55 kg person, it is 1.6 to 2.0 mg. Splitting the dose maintains stable blood levels. Inject 1.0 to 1.25 mg every three days, or half the weekly total twice per week. Consistency is key for tissue repair.
Reconstitution and Injection Protocol
TB-500 typically comes as a lyophilized powder in 5 mg vials. Reconstitute with bacteriostatic water. For a 5 mg vial, add 2 mL of water to get a concentration of 2.5 mg/mL. Then, a 1.0 mg dose equals 0.4 mL on an insulin syringe. Use a 1 mL syringe with a 30-gauge needle for subcutaneous injection. Inject into fatty tissue around the abdomen or thigh. Rotate sites to avoid irritation. Some protocols suggest injecting near the injury site, but systemic absorption works well for most injuries. Store reconstituted TB-500 in the refrigerator and use within 30 days. Always follow sterile procedures to prevent contamination.
Cycle Length and Timing for Optimal Healing
A standard TB-500 cycle lasts four to six weeks, followed by an equal off period. For acute injuries, a four-week cycle often suffices. Chronic conditions may benefit from six weeks. Some users extend to eight weeks, but longer cycles increase the risk of receptor downregulation. After a cycle, take a break to let your body reset. During the cycle, inject twice weekly. Many report noticeable improvements in pain and mobility within two to three weeks. Full tissue remodeling takes longer. Combining TB-500 with MOTS-c for muscle preservation may support overall recovery, though they act through different mechanisms.
TB-500 Dosage for Specific Injuries
Different injuries may require slight dosage tweaks. For tendonitis or ligament sprains, the standard 2.0 to 2.5 mg per week works well. For muscle tears, some users increase to 3.0 mg per week for the first two weeks, then drop to maintenance. For post-surgical recovery, a loading phase of 4.0 mg per week for two weeks can jumpstart healing, though this is less common. Skin wounds and burns may respond to lower doses of 1.5 mg per week. Always start at the lower end and adjust based on response. Track your progress with pain scales and functional tests. If you experience no improvement after two weeks, consider a slight increase within the safe range.
Combining TB-500 with BPC-157
TB-500 is often stacked with BPC-157 for synergistic healing. BPC-157 is a gastric peptide that promotes angiogenesis and tissue repair. Together, they target different pathways. A common stack is 2.0 mg TB-500 per week plus 250 to 500 mcg BPC-157 daily. BPC-157 is injected once or twice daily. This combination is popular for stubborn injuries like tennis elbow or partial tendon tears. No direct drug interactions are known, but both increase blood vessel growth. Monitor for any unusual side effects. The weight-based TB-500 dosage still applies when stacking. Do not reduce the TB-500 dose unless you experience side effects.
Side Effects and Safety Considerations
TB-500 is generally well-tolerated. Reported side effects include temporary fatigue, headache, or injection site redness. These usually resolve within a day. Because TB-500 promotes angiogenesis, there is a theoretical risk of feeding existing tumors. Avoid use if you have cancer or a history of it. Pregnant or nursing women should not use TB-500. Long-term safety data is limited. Stick to recommended cycles and dosages. If you experience dizziness, rapid heartbeat, or allergic reactions, discontinue use and seek medical help. Always source TB-500 from reputable suppliers to ensure purity. Third-party testing is a must.
Where to Buy TB-500 and Price Considerations
You can buy TB-500 online from peptide vendors. Prices vary by region and supplier. A 5 mg vial typically costs between $30 and $60 USD. Some vendors offer bulk discounts. When buying TB-500, look for certificates of analysis. Avoid suspiciously cheap products. In Canada, prices are similar, often ranging from $40 to $70 CAD per 5 mg vial. Shipping restrictions may apply. Always check local regulations. Research peptides are sold for laboratory use only. For tissue repair peptides, quality matters more than price. A reliable vendor will provide clear labeling and storage instructions.
Monitoring Progress and Adjusting Dosage
Track your healing with objective measures. Use a pain diary, range of motion tests, or imaging if available. If you see steady improvement, maintain the dose. If progress stalls after two weeks, consider a small increase of 0.5 mg per week. Do not exceed 4.0 mg per week without medical supervision. Some users report better results when injecting closer to the injury site, though evidence is anecdotal. Stay hydrated and maintain a protein-rich diet to support tissue repair. Remember that peptides are tools, not magic. Rest and physical therapy remain essential.

Frequently Asked Questions About TB-500 Dosing
Can I take TB-500 every day?
No, daily dosing is unnecessary and wasteful. TB-500 has a long half-life of several days. Twice-weekly injections maintain stable levels. Daily micro-dosing offers no proven benefit.
What if I miss a dose?
Take it as soon as you remember, then adjust the next dose to maintain the schedule. Do not double up. Consistency matters more than exact timing.
Is TB-500 safe for long-term use?
Long-term safety is unknown. Stick to cycles of four to six weeks with equal breaks. Prolonged use may increase angiogenesis risks.
Can I use TB-500 for anti-aging?
Some use it for skin and hair benefits, but evidence is weak. Tissue repair remains its primary use. For anti-aging, consider Epitalon for telomere protection as a more targeted option.
Does TB-500 require a prescription?
In most countries, TB-500 is sold as a research chemical and does not require a prescription. However, it is not approved for human use by the FDA. Consult a doctor before use.
Conclusion: Personalizing Your TB-500 Dosage
A TB-500 dosage calculator based on weight provides a safe starting point for tissue repair. The standard 2.0 to 2.5 mg per week works for most, but adjusting for body weight optimizes results. Split doses, follow a cycle, and monitor your body's response. Combine with proper nutrition and rest for best outcomes. Always prioritize product quality and safety. With the right approach, TB-500 can significantly accelerate healing and get you back to full function.
