TB-500 5mg dosage for tendon repair in Canada typically starts at 2.5mg twice weekly for the first 4 weeks, then drops to 2.5mg weekly for maintenance. This peptide, a synthetic version of thymosin beta-4, promotes cell migration and blood vessel formation to speed healing. Canadian researchers often buy TB-500 5mg vials for tendon injuries, but dosing must match the injury severity and cycle length.
What is TB-500 and how does it repair tendons
TB-500 is a synthetic fragment of thymosin beta-4, a naturally occurring protein that regulates actin. Actin is the building block of cell structure and movement. When a tendon is injured, TB-500 helps new blood vessels form, reduces inflammation, and recruits stem cells to the damaged area. Tendons have poor blood supply, so this angiogenic effect is critical. In animal studies, TB-500 accelerated healing of Achilles tendon injuries by up to 40 percent compared to controls.
For tendon repair, TB-500 works best when combined with a structured rehab program. It does not replace physiotherapy. The peptide creates a better healing environment, but mechanical loading is still needed to align collagen fibers properly. Canadian researchers often pair TB-500 with BPC-157 for a synergistic effect. You can read more about side effects of the BPC-157 and TB-500 blend in Canada before stacking them.
TB-500 5mg dosage protocol for tendon repair
The most common TB-500 5mg dosage for tendon repair is 2.5mg injected subcutaneously twice per week. This totals 5mg per week, which matches the vial size. A typical cycle lasts 4 to 6 weeks for acute tendon injuries. Chronic tendinopathy may require 8 to 12 weeks. After the loading phase, many researchers drop to 2.5mg once weekly for maintenance.
Here is a standard protocol for a 5mg vial:
- Weeks 1-4: 2.5mg twice weekly (total 5mg per week)
- Weeks 5-8: 2.5mg once weekly (maintenance)
- Optional: 2.5mg every 10-14 days for ongoing tendon health
Some protocols use a higher front-loading dose. For example, 5mg twice weekly for the first 2 weeks, then 2.5mg twice weekly. This is more aggressive and may increase side effect risk. Most Canadian researchers stick with the standard 2.5mg twice weekly. The half-life of TB-500 is about 2 to 3 days, so twice-weekly dosing keeps blood levels stable.
How to reconstitute TB-500 5mg
Reconstituting TB-500 5mg is straightforward. Add 2ml of bacteriostatic water to the vial. This gives a concentration of 2.5mg per ml. Then a 2.5mg dose equals 1ml, or 100 units on an insulin syringe. If you prefer smaller injection volumes, add 1ml of bacteriostatic water. Then 2.5mg equals 0.5ml, or 50 units.
Always use bacteriostatic water, not sterile water. Bacteriostatic water contains benzyl alcohol, which prevents bacterial growth. Store the reconstituted vial in the refrigerator. It remains stable for about 30 days. Do not shake the vial. Swirl gently to dissolve the powder. TB-500 is a fragile peptide, and vigorous shaking can damage it.

TB-500 injection sites for tendon injuries
TB-500 works systemically, so the injection site does not need to be directly over the injured tendon. Most researchers inject subcutaneously into the abdomen or thigh. Some prefer to inject near the injury site, but there is no evidence this improves outcomes. The peptide travels through the bloodstream to reach damaged tissue. Rotate injection sites to avoid irritation. Common sites include the abdomen, upper thigh, or upper arm.
Use an insulin syringe with a 30 or 31 gauge needle. Inject at a 45-degree angle into pinched skin. The injection is virtually painless. If you are treating an Achilles tendon, do not inject into the tendon itself. That can cause further damage. Always inject into subcutaneous fat.
TB-500 results timeline for tendon repair
Most Canadian researchers report noticeable improvement within 2 to 3 weeks. Pain decreases first, followed by increased range of motion. Full tendon remodeling takes longer, often 6 to 12 weeks. TB-500 does not provide instant pain relief. It accelerates the natural healing cascade. Expect gradual progress, not overnight results.
In one animal study, TB-500 improved collagen deposition and tensile strength in injured rat Achilles tendons. The treated group showed 30 percent greater load to failure at 4 weeks compared to saline controls. Human data is limited, but anecdotal reports from athletes are overwhelmingly positive. Many use TB-500 for chronic tendinopathy that has not responded to rest or physiotherapy.

TB-500 side effects and safety in Canada
TB-500 is generally well tolerated. The most common side effects are mild injection site reactions: redness, swelling, or itching. These resolve within a few hours. Some users report transient fatigue or headache after the first few doses. These usually disappear as the body adjusts. No serious adverse events have been reported in human use at standard doses.
Long-term safety data is lacking. TB-500 is not approved by Health Canada for human use. It is sold as a research chemical. In Canada, buying TB-500 for personal use falls into a legal gray area. It is not a controlled substance, but it is not authorized for human consumption. Researchers should handle it as a laboratory peptide only.
Do not use TB-500 if you have active cancer. Thymosin beta-4 promotes angiogenesis, which could theoretically feed tumor growth. This is a theoretical risk based on mechanism, not clinical evidence. Still, anyone with a history of cancer should avoid TB-500. Pregnant or nursing women should also avoid it.
Where to buy TB-500 5mg in Canada
Canadian researchers can buy TB-500 5mg from several online peptide vendors. Prices range from $40 to $80 CAD per vial, depending on purity and brand. Look for vendors that provide third-party lab testing. A certificate of analysis should confirm at least 98 percent purity. Avoid vendors that sell pre-mixed liquid TB-500. The peptide degrades quickly in solution. Always buy lyophilized powder and reconstitute it yourself.
Shipping within Canada is usually fast, often 2 to 5 business days. Some vendors ship from the US, which can take longer and may incur customs delays. For domestic options, search for "TB-500 5mg Canada" or "buy TB-500 peptide Canada". Compare prices, but do not sacrifice quality for a lower price. A cheap vial that is underdosed or contaminated is worthless.

TB-500 vs BPC-157 for tendon repair
TB-500 and BPC-157 are often compared for tendon healing. They work through different mechanisms. TB-500 primarily promotes cell migration and angiogenesis. BPC-157 upregulates growth factor receptors and promotes angiogenesis too, but it also has a direct effect on tendon fibroblasts. Many researchers stack them for a synergistic effect.
TB-500 has a longer half-life and can be dosed less frequently. BPC-157 requires daily injections. TB-500 is better for systemic healing and large injuries. BPC-157 is better for localized injuries, especially in the gut or joints. For tendon repair, the combination is often more effective than either alone. A common stack is 2.5mg TB-500 twice weekly plus 250mcg BPC-157 twice daily.
Cost is another factor. TB-500 5mg vials are more expensive per milligram than BPC-157. But the lower dosing frequency offsets this. A 4-week TB-500 cycle costs about $80 to $160 CAD. A BPC-157 cycle costs about $60 to $120 CAD. Stacking both doubles the cost, but many users find the results worth it.
TB-500 cycle length and off periods
A typical TB-500 cycle for tendon repair lasts 4 to 6 weeks. After that, take at least 2 weeks off. This prevents receptor downregulation and allows the body to reset. Some researchers run longer cycles of 8 to 12 weeks for chronic injuries. But longer cycles increase the risk of side effects and reduce effectiveness over time.
Do not run TB-500 continuously. The body may develop antibodies to the synthetic peptide. This can reduce its effectiveness in future cycles. Cycling on and off is standard practice. A common schedule is 4 weeks on, 2 weeks off, then repeat if needed. For maintenance, some use 2.5mg every 10 to 14 days indefinitely. But this is not well studied.
Track your progress with objective measures. Range of motion, pain scores, and functional tests are better than subjective feelings. If you see no improvement after 4 weeks, reassess your protocol. The injury may need a different approach, or the peptide may not be working for you.
Frequently asked questions about TB-500 5mg dosage
Can I inject TB-500 directly into the tendon?
No. Never inject any peptide directly into a tendon. This can cause mechanical damage and worsen the injury. TB-500 works systemically, so subcutaneous injection is sufficient. Inject into the abdomen, thigh, or upper arm. The peptide will travel to the injured tendon through the bloodstream.
How long does a 5mg vial of TB-500 last?
At the standard dose of 2.5mg twice weekly, a 5mg vial lasts one week. If you use 2.5mg once weekly for maintenance, it lasts two weeks. Always reconstitute with bacteriostatic water and store in the refrigerator. Use within 30 days for best potency.
Is TB-500 legal in Canada?
TB-500 is not a controlled substance in Canada. It is legal to buy and possess for
