BPC-157 and TB-500 are two of the most researched peptides for tendon healing, and many Canadian researchers ask which one works better. The short answer: BPC-157 is stronger for localized tendon repair and angiogenesis, while TB-500 excels at systemic recovery and reducing inflammation. For serious tendon injuries, a stack of both often delivers the best results. This guide breaks down dosage, stacking protocols, and what to expect when buying peptides in Canada.
How BPC-157 and TB-500 Work on Tendons
BPC-157 is a synthetic peptide derived from a protein found in gastric juice. It promotes tendon healing by upregulating growth hormone receptors and increasing fibroblast activity. TB-500 is a fragment of thymosin beta-4, a naturally occurring protein that regulates actin. Actin is the building block of cell movement and structure, which matters for tendon repair. Both peptides accelerate healing, but they do so through different pathways.
BPC-157 works locally. When injected near a damaged tendon, it increases blood vessel formation and collagen production. TB-500 works systemically. It travels through the bloodstream and reduces inflammation at injury sites. This is why many researchers combine them for a synergistic effect.
BPC-157 Dosage for Tendon Healing
For tendon injuries, the standard BPC-157 dosage is 250 to 500 mcg per day. Most researchers split this into two injections: one in the morning and one in the evening. The injection should be as close to the injury site as possible, but subcutaneous injection into the abdomen or thigh also works because BPC-157 is systemic. A typical cycle lasts 4 to 6 weeks, followed by a break of at least 2 weeks.
If you are using a 5 mg vial of BPC-157, you can reconstitute it with 2 mL of bacteriostatic water. This gives you a concentration of 2500 mcg per mL. A 250 mcg dose would be 0.1 mL on an insulin syringe. For a detailed reconstitution guide, see how to mix and dose BPC-157 5mg in Canada.
TB-500 Dosage for Tendon Healing
TB-500 is typically dosed at 2.5 to 5 mg per week, split into two injections. For example, a researcher might inject 2.5 mg on Monday and 2.5 mg on Thursday. Some protocols use a loading phase of 4 to 6 mg per week for the first two weeks, then drop to a maintenance dose of 2.5 mg per week. TB-500 has a longer half-life than BPC-157, so less frequent dosing is effective. A cycle of 4 to 6 weeks is common for tendon injuries.
TB-500 is usually injected subcutaneously or intramuscularly. Because it works systemically, the injection site does not need to be near the injury. Many researchers inject into the abdomen or thigh.
BPC-157 vs TB-500: Key Differences for Tendon Healing
BPC-157 is more potent for localized tendon repair. It directly stimulates angiogenesis and collagen synthesis at the injury site. TB-500 is better for reducing systemic inflammation and promoting cell migration. If you have a single tendon injury, BPC-157 alone may be sufficient. If you have multiple injuries or widespread inflammation, TB-500 adds more value.
Another difference is dosing frequency. BPC-157 requires daily injections because its half-life is short. TB-500 can be injected every 3 to 4 days. This makes TB-500 more convenient for researchers who prefer fewer injections.
Cost is also a factor. In Canada, a 5 mg vial of BPC-157 typically costs between $40 and $80 CAD. A 5 mg vial of TB-500 costs between $50 and $100 CAD. Because TB-500 is dosed in larger amounts, a cycle of TB-500 is usually more expensive than a cycle of BPC-157.
Stacking BPC-157 and TB-500 for Tendon Healing
Stacking BPC-157 and TB-500 is a popular protocol for stubborn tendon injuries. The idea is to combine BPC-157's local repair effects with TB-500's systemic anti-inflammatory action. A common stack looks like this:
- BPC-157: 250 to 500 mcg per day, split into two injections
- TB-500: 2.5 mg twice per week
- Cycle length: 4 to 6 weeks
Some researchers add a third peptide like CJC-1295 or Ipamorelin to boost growth hormone and speed recovery. However, for tendon healing specifically, the BPC-157 and TB-500 stack is the most evidence-backed.

What Results Can You Expect?
Most researchers report noticeable improvement in tendon pain and function within 2 to 4 weeks of starting BPC-157 or TB-500. Full healing of a chronic tendon injury may take 6 to 8 weeks. Anecdotal reports from Canadian researchers suggest that BPC-157 alone reduces pain by 50 to 70 percent in the first month. Adding TB-500 often accelerates this timeline by 1 to 2 weeks.
It is important to note that these peptides are for research purposes only. They are not approved by Health Canada for human use. All results are from animal studies or anecdotal reports.
Side Effects and Safety
BPC-157 and TB-500 have a good safety profile in animal studies. The most common side effect is mild injection site irritation. Some researchers report temporary fatigue or headache. There are no known serious adverse effects at standard research dosages. However, long-term human safety data is lacking. Always follow proper sterile technique when reconstituting and injecting peptides.

Where to Buy BPC-157 and TB-500 in Canada
When buying peptides in Canada, choose a vendor that provides third-party lab testing and ships from within Canada. This avoids customs delays and ensures product quality. Prices for BPC-157 5 mg range from $40 to $80 CAD. TB-500 5 mg ranges from $50 to $100 CAD. Some vendors offer bundle deals for stacking both peptides.

Final Verdict: BPC-157 or TB-500 for Tendon Healing?
For a single tendon injury, start with BPC-157 at 250 to 500 mcg per day. It is cheaper, requires smaller doses, and has strong evidence for local tendon repair. If you have multiple injuries or systemic inflammation, add TB-500 at 2.5 mg twice per week. For the fastest results, stack both peptides for 4 to 6 weeks. Always source from a reputable Canadian vendor and follow proper reconstitution protocols.
