BPC-157 dosage for tissue repair typically ranges from 250 mcg to 500 mcg twice daily, depending on the injury stage and severity. This guide breaks down how to dose BPC-157 through the inflammatory, proliferative, and remodeling phases of healing. You will learn stage-specific protocols, injection methods, and timing to optimize recovery.
Understanding Tissue Repair Stages
Tissue repair follows three overlapping phases: inflammation, proliferation, and remodeling. Each stage has distinct cellular events, and BPC-157 interacts with them differently. Dosing should align with these biological windows. The inflammatory phase begins immediately after injury and lasts up to a few days. It involves clotting, immune cell recruitment, and debris clearance. The proliferative phase rebuilds tissue with new cells and blood vessels over days to weeks. Remodeling strengthens and reorganizes the tissue over weeks to months. BPC-157 accelerates healing by promoting angiogenesis, upregulating growth factors, and modulating inflammation. Adjusting dosage and timing per stage may enhance outcomes.
BPC-157 Mechanism in Tissue Repair
BPC-157 is a synthetic peptide derived from a protective protein in gastric juice. It promotes healing in tendons, ligaments, muscles, and even the gut. Research shows it increases vascular endothelial growth factor (VEGF) and fibroblast growth factor (FGF), driving new blood vessel formation. It also modulates nitric oxide and reduces oxidative stress. During inflammation, BPC-157 can dampen excessive cytokine release without suppressing necessary immune activity. In proliferation, it boosts fibroblast migration and collagen synthesis. In remodeling, it may improve collagen alignment and tensile strength. These effects are dose-dependent, making precise dosing critical.
General BPC-157 Dosage Guidelines
Standard BPC-157 dosage for tissue repair is 250-500 mcg per injection, administered one to two times daily. Total daily doses of 500-1000 mcg are common. Some protocols use a loading phase of 500 mcg twice daily for the first week, then drop to 250 mcg twice daily for maintenance. Injection site matters: for localized injuries, inject as close to the damaged area as safely possible. For systemic healing or gut issues, subcutaneous abdominal injections work well. Always reconstitute BPC-157 with bacteriostatic water. A typical vial contains 5 mg of peptide. Adding 2 mL of bacteriostatic water yields a concentration of 2500 mcg/mL. Then 0.1 mL equals 250 mcg. Use an insulin syringe for accurate measurement.
Dosing for the Inflammatory Phase
In the first 1-5 days post-injury, inflammation dominates. The goal is to control swelling and pain while setting the stage for repair. BPC-157 dosage during this phase often starts at 250 mcg twice daily. This lower dose may modulate inflammation without blunting the natural healing cascade. Some users report faster pain relief with 500 mcg twice daily, but human data is limited. Animal studies suggest BPC-157 reduces inflammatory markers like TNF-alpha and IL-6. If pain is severe, a short course of 500 mcg twice daily for 3 days may be beneficial. Inject near the injury if possible. For example, a sprained ankle would get injections around the lateral ligaments. Rotate injection sites to avoid irritation.
Dosing for the Proliferative Phase
As inflammation subsides, proliferation kicks in. This phase lasts from roughly day 3 to week 3, depending on the injury. Fibroblasts lay down new collagen, and blood vessels grow into the wound. BPC-157 dosage often increases to 500 mcg twice daily during this stage. The higher dose supports robust angiogenesis and collagen production. One study on rat Achilles tendons showed that BPC-157 improved fibroblast density and collagen fiber alignment. For larger injuries like muscle tears, some protocols use 500 mcg three times daily for the first two weeks. However, twice-daily dosing is more practical and still effective. Continue injecting near the injury site. If the injury is deep, like a rotator cuff, consider subcutaneous injections in the upper arm rather than intramuscular, as BPC-157 is systemic but local proximity may help.
Dosing for the Remodeling Phase
Remodeling begins around week 3 and can last months. Collagen matures from type III to type I, and tissue strength improves. BPC-157 dosage often tapers to 250 mcg once or twice daily. The goal shifts from building tissue to refining it. A lower maintenance dose may support optimal collagen cross-linking without overstimulation. Some users continue 250 mcg twice daily for 4-6 weeks, then drop to once daily for another month. For chronic injuries, a longer course at 250 mcg twice daily may be needed. Listen to your body: if pain returns or progress stalls, consider a temporary increase back to 500 mcg twice daily. Injections can remain localized or switch to systemic if the injury is widespread.
Injection Methods and Timing
BPC-157 is typically injected subcutaneously or intramuscularly. Subcutaneous injections are easier and less painful. Use a 31-gauge, 5/16-inch insulin syringe. Pinch the skin, insert at a 45-degree angle, and inject slowly. For intramuscular injections, use a longer needle (1/2 inch or more) and inject into the muscle belly near the injury. Timing matters: inject on an empty stomach if possible, though BPC-157 is not known to interact with food. Many users inject first thing in the morning and before bed. Consistency is key. If you miss a dose, take it as soon as you remember, but do not double up. Proper reconstitution is critical to maintain peptide stability. For guidance on reconstitution, see our article on choosing between bacteriostatic and sterile water for peptide reconstitution.
Combining BPC-157 with Other Peptides
BPC-157 is often stacked with TB-500 (Thymosin Beta-4) for synergistic tissue repair. TB-500 promotes cell migration and reduces inflammation, complementing BPC-157's angiogenic effects. A common stack: BPC-157 250-500 mcg twice daily plus TB-500 2.5-5 mg twice weekly. For acute injuries, some add growth hormone secretagogues like Ipamorelin or CJC-1295 to boost systemic IGF-1. However, start with BPC-157 alone to assess tolerance. When combining, inject peptides separately to avoid interactions. Use different syringes or at least different injection sites. If you reconstitute multiple peptides, be aware of potential aggregation issues. Learn more in our post on avoiding aggregation when co-reconstituting peptides.
BPC-157 Dosage for Specific Injuries
Different tissues heal at different rates, and BPC-157 dosage may vary accordingly. For tendon injuries like tennis elbow, 250-500 mcg twice daily injected near the lateral epicondyle is common. A 4-6 week course often yields significant improvement. For ligament sprains, such as an ACL tear, higher doses of 500 mcg twice daily may be needed for 6-8 weeks. Muscle tears respond well to 500 mcg twice daily for 2-4 weeks, then tapering. For bone fractures, animal studies show BPC-157 accelerates callus formation. A dose of 250-500 mcg twice daily systemically may help. Gut healing uses oral BPC-157, but injectable BPC-157 also has systemic effects on the gastrointestinal tract. Doses of 250-500 mcg twice daily subcutaneously can improve leaky gut and ulcers. Always consult a healthcare provider before starting any new regimen.
Safety and Side Effects
BPC-157 has a strong safety profile in animal studies, with no reported toxicity at therapeutic doses. Human data is limited but suggests minimal side effects. Some users report mild nausea, dizziness, or injection site reactions. These usually resolve quickly. To minimize injection site pain, rotate sites and use proper technique. Avoid BPC-157 if you have active cancer, as its angiogenic properties could theoretically promote tumor growth. Pregnant or breastfeeding women should avoid it due to lack of safety data. Long-term effects are unknown. Start with the lowest effective dose and monitor your response. If you experience any adverse effects, discontinue use and seek medical advice.
Monitoring Progress and Adjusting Dosage
Track your healing with objective measures when possible. For tendon injuries, monitor pain levels, range of motion, and strength. Use a journal to record daily dosages and symptoms. If you plateau, consider a dosage increase or adding TB-500. If you experience side effects, reduce the dose. Some users find that splitting the total daily dose into three smaller injections provides better coverage. For example, 200 mcg three times daily instead of 300 mcg twice daily. This may maintain more stable peptide levels. However, convenience often dictates twice-daily dosing. Remember that BPC-157 is a research peptide, not an approved drug. Its use is experimental. Always source from reputable suppliers to ensure purity and avoid contamination. Proper storage is also vital: keep lyophilized powder in the freezer and reconstituted solution in the refrigerator, away from light.

Practical Protocol Example
Here is a sample 8-week BPC-157 protocol for a moderate tendon injury:
- Week 1 (Inflammatory): BPC-157 250 mcg twice daily, injected near the injury.
- Weeks 2-4 (Proliferative): BPC-157 500 mcg twice daily, continue local injections.
- Weeks 5-8 (Remodeling): BPC-157 250 mcg twice daily, can switch to systemic if desired.
After week 8, reassess. If fully healed, stop. If still healing, continue at 250 mcg once daily for another 4 weeks. This protocol assumes a 5 mg vial reconstituted with 2 mL bacteriostatic water. Using a 0.3 mL insulin syringe, draw to the 10-unit mark for 250 mcg (0.1 mL) or the 20-unit mark for 500 mcg (0.2 mL). Always
