TB-500 Dosage Per Week for Tissue Repair: A Practical Guide

July 15, 2026

For most users, the standard TB-500 dosage per week for tissue repair falls between 2.5 mg and 5 mg, split into two or three injections. This range is widely used to support recovery from muscle strains, ligament injuries, and chronic inflammation. The exact amount depends on your body weight, injury severity, and treatment phase. Below, we break down the science, practical dosing schedules, and safety considerations to help you use this peptide effectively.

Why TB-500 Matters for Tissue Repair

TB-500 is a synthetic fragment of thymosin beta-4, a protein naturally produced in the body. It plays a key role in actin regulation, cell migration, and angiogenesis. These processes are essential for wound healing and tissue regeneration. By promoting new blood vessel formation and reducing inflammation, TB-500 accelerates repair in muscles, tendons, and ligaments. Research shows it can also enhance hair growth and reduce scar formation. For athletes and active individuals, this peptide offers a way to bounce back faster from injuries that would otherwise sideline them for weeks.

Unlike some peptides that primarily boost growth hormone, TB-500 works directly at the injury site. It recruits stem cells and modulates the immune response to create an optimal healing environment. This makes it particularly valuable for soft tissue injuries. If you are dealing with a nagging tendon issue or a recent muscle tear, understanding the correct TB-500 dosing is the first step toward recovery. You can also explore how other peptides support healing, such as IGF-1 LR3 for tendon and ligament recovery, which works through different mechanisms.

Standard TB-500 Dosage Per Week: The Numbers

The most common TB-500 dosage per week is 2.5 mg to 5 mg total. This is typically divided into two or three injections spread evenly across the week. For a 5 mg weekly dose, you might inject 2.5 mg twice a week or about 1.7 mg three times a week. Some protocols start with a higher loading phase of 5 mg to 10 mg per week for the first two to four weeks, then drop to a maintenance dose of 2.5 mg per week. Body weight can influence the dose: a 200-pound person may need closer to 5 mg weekly, while a 150-pound person might see results with 2.5 mg.

Here is a simple breakdown based on common protocols:

Loading phase (weeks 1-4): 5 mg to 10 mg per week, split into 2-3 injections.
Maintenance phase (weeks 5+): 2.5 mg to 5 mg per week, split into 2 injections.
Acute injury protocol: 2.5 mg to 5 mg twice weekly for 4-6 weeks, then reassess.

These numbers come from anecdotal reports and animal studies. Human clinical trials are limited, so the community has developed these guidelines through experience. Always start at the lower end to assess your response. TB-500 has a half-life of about 2-3 days, which is why frequent dosing maintains steady levels in the body. For cartilage-specific injuries, you might also consider GHK-Cu for cartilage regeneration, which targets a different aspect of joint repair.

How to Reconstitute and Measure Your Dose

TB-500 typically comes as a lyophilized powder in vials of 5 mg or 10 mg. You need to reconstitute it with bacteriostatic water before injection. The amount of water you add determines the concentration. For a 5 mg vial, adding 1 mL of water gives you a concentration of 5 mg/mL. If you want a 2.5 mg dose, you would draw 0.5 mL into the syringe. Use an insulin syringe with a fine needle for subcutaneous or intramuscular injection.

Here is a step-by-step guide:

Wipe the vial tops and your injection site with alcohol swabs.
Draw 1 mL of bacteriostatic water into a syringe.
Slowly inject the water into the TB-500 vial, letting it slide down the glass wall to avoid foaming.
Gently swirl the vial until the powder dissolves completely. Do not shake.
Store the reconstituted peptide in the refrigerator. It remains stable for about 7-10 days.
For each dose, draw the required volume based on your desired mg amount.

Accurate measurement is crucial. If you use a 10 mg vial and add 2 mL of water, each 0.5 mL contains 2.5 mg of TB-500. Always double-check your math. Inject subcutaneously into the belly fat or intramuscularly near the injury site for potentially better localized effects. Rotate injection sites to prevent irritation.

TB-500 Dosing Schedule for Different Injuries

Your TB-500 dosing schedule should match the type and severity of your injury. For acute muscle tears, a common approach is 2.5 mg twice weekly for 4-6 weeks. This provides a steady supply of the peptide during the critical early healing phase. For chronic tendonitis or joint pain, a longer cycle of 5 mg per week for 8-12 weeks may be more effective. Some users combine TB-500 with BPC-157 for synergistic effects, as BPC-157 works locally in the gut and injured tissue.

Here are sample schedules:

Muscle strain (grade 1-2): 2.5 mg every 3 days for 4 weeks.
Ligament sprain: 5 mg per week split into two doses for 6 weeks.
Post-surgery recovery: 5 mg twice weekly for 2 weeks, then 2.5 mg twice weekly for 4 more weeks.
Chronic inflammation: 2.5 mg every 3 days for 8-12 weeks.

Listen to your body. If pain and swelling decrease rapidly, you might shorten the cycle. If progress stalls, consider increasing the dose within the safe range. Always take breaks between cycles to prevent receptor desensitization. A typical off-period is 4 weeks after a 6-8 week cycle. This helps maintain the peptide's effectiveness over time.

Combining TB-500 with Other Tissue Repair Peptides

Many researchers stack TB-500 with other peptides to enhance healing. The most popular combination is TB-500 and BPC-157. BPC-157 promotes angiogenesis and speeds up wound healing through a different pathway. Together, they can address both systemic and local repair. A typical stack might involve 2.5 mg of TB-500 twice weekly plus 250 mcg of BPC-157 daily. This dual approach is common for stubborn injuries like rotator cuff tears or Achilles tendonitis.

Another option is adding growth hormone secretagogues like Ipamorelin or CJC-1295. These boost natural growth hormone production, which supports tissue repair and overall recovery. However, TB-500 works independently of growth hormone, so the combination is safe. For joint-specific issues, GHK-Cu's potential for cartilage regeneration makes it a logical addition. Always introduce one new peptide at a time to monitor for side effects.

Expected Results and Timeline

With consistent TB-500 dosing, most users notice reduced pain and improved mobility within 2-4 weeks. Acute injuries may heal 30-50% faster than without the peptide. For example, a grade 2 muscle strain that normally takes 6 weeks to heal might resolve in 4 weeks with TB-500. Chronic conditions like tendonosis may take longer, often 8-12 weeks, to show significant improvement. The peptide does not just mask pain; it promotes actual tissue repair, so results are lasting.

Keep a log of your symptoms and dosing schedule. Track pain levels, range of motion, and any side effects. This helps you fine-tune your protocol. Some users report better sleep and improved skin quality as secondary benefits. These effects likely stem from reduced systemic inflammation. However, TB-500 is not a magic bullet. It works best when combined with proper nutrition, physical therapy, and adequate rest.

Potential Side Effects and Safety

TB-500 is generally well-tolerated at the recommended doses. The most common side effects are mild and temporary. These include:

Injection site reactions like redness or itching.
Fatigue or lethargy, especially during the first week.
Headaches, which usually subside with hydration.
A temporary increase in hunger.

More serious risks are rare but can include allergic reactions. If you experience difficulty breathing, swelling, or severe rash, seek medical attention immediately. Long-term safety data is limited, so cycling is recommended. Avoid TB-500 if you have cancer or are at high risk, as it may promote angiogenesis in tumors. Pregnant or nursing women should not use this peptide. Always consult a healthcare professional before starting any new peptide regimen.

Where to Find Quality TB-500

Because TB-500 is sold for research purposes, quality varies widely. Look for vendors that provide third-party testing and certificates of analysis. The peptide should be at least 98% pure. Avoid deals that seem too cheap, as they may be underdosed or contaminated. Proper storage is also key: keep the lyophilized powder in a cool, dark place, and refrigerate after reconstitution. If you are new to peptides, start with a small order to test the product's effectiveness and your tolerance.

For those interested in complementary therapies, IGF-1 LR3 offers unique benefits for tendon and ligament recovery that may enhance your overall healing strategy. Combining multiple evidence-based approaches can lead to better outcomes.
