To reconstitute a BPC-157 and TB-500 blend vial containing 5mg of each peptide, you typically add 1mL to 2mL of bacteriostatic water, giving a combined concentration of 5mg/mL to 2.5mg/mL per peptide. In Canada, this blend is sold for research purposes only, and a standard starting dose is 250mcg to 500mcg of each peptide injected subcutaneously once or twice daily.
What Is a BPC-157 and TB-500 Blend?
BPC-157 and TB-500 are two research peptides often combined into a single vial for convenience. BPC-157 is a pentadecapeptide derived from a protein found in gastric juice, known for its potential to accelerate healing of tendons, ligaments, and the gut lining. TB-500 is a synthetic fragment of thymosin beta-4, a naturally occurring peptide that promotes cell migration, angiogenesis, and tissue repair. When blended at a 5mg/5mg ratio, each vial contains equal amounts of both peptides, allowing researchers to administer them together in one injection.
This combination is popular among Canadian researchers studying recovery from soft tissue injuries, post-surgical healing, and even gastrointestinal repair. The blend is not approved by Health Canada for human use, and all handling should follow laboratory safety protocols.
Why Reconstitute Correctly Matters
Proper reconstitution ensures accurate dosing and peptide stability. BPC-157 and TB-500 are lyophilized powders that degrade quickly if mixed with the wrong solvent or stored improperly. Using bacteriostatic water (0.9% benzyl alcohol) is standard because it inhibits bacterial growth and allows multiple draws from the same vial over several weeks. Using sterile water alone increases contamination risk after the first puncture.
Incorrect reconstitution can lead to underdosing, wasted peptide, or even injection site reactions. For researchers in Canada, where peptides are often purchased from online vendors, understanding the math behind reconstitution is essential for reproducible results.
Step-by-Step Reconstitution Guide for 5mg/5mg Blend
Follow these steps to reconstitute a 5mg/5mg BPC-157 and TB-500 blend vial. Always work in a clean, sterile environment.
- Gather supplies: One vial of lyophilized blend, one vial of bacteriostatic water, alcohol swabs, 1mL or 3mL syringe with a large needle (21-25G) for mixing, and smaller insulin syringes (29-31G) for injection.
- Clean the vial tops: Wipe the rubber stoppers of both vials with alcohol swabs and let dry.
- Draw bacteriostatic water: For a 5mg/5mg blend, adding 1mL of water gives 5mg/mL of each peptide. Adding 2mL gives 2.5mg/mL of each. Most researchers prefer 2mL for easier small-dose measurement.
- Inject water slowly: Insert the needle into the peptide vial at an angle, aiming the stream against the glass wall to avoid foaming. Do not shake.
- Gently swirl: Roll the vial between your fingers until the powder fully dissolves. The solution should be clear and colorless.
- Store properly: Keep the reconstituted vial refrigerated at 2-8°C. Avoid freezing and direct light.

Calculating Your Dose from the Blend
Because the blend contains two peptides in equal amounts, every dose delivers the same quantity of each. For example, if you reconstitute with 2mL of bacteriostatic water, the concentration is 2.5mg/mL for BPC-157 and 2.5mg/mL for TB-500. To inject 250mcg of each peptide, you would draw 0.1mL (10 units on an insulin syringe).
Here is a quick reference table for common doses using 2mL reconstitution:
- 250mcg each = 0.1mL (10 units)
- 500mcg each = 0.2mL (20 units)
- 1mg each = 0.4mL (40 units)
If you reconstitute with 1mL, the concentrations double, so the same doses require half the volume. Always double-check your math before injecting.
Recommended Dosage Protocol for Research
For research purposes, a typical BPC-157 and TB-500 blend dosage ranges from 250mcg to 500mcg of each peptide per injection. Many protocols call for one injection daily, while others split the dose into two injections (morning and evening) for more stable blood levels. A common cycle lasts 4 to 8 weeks, followed by a break of equal length.
For acute injuries, some researchers use a front-loading approach: 500mcg of each peptide twice daily for the first week, then reduce to 250mcg twice daily for maintenance. However, no human clinical trials have established optimal dosing, so all protocols are experimental.

Injection Technique and Site Rotation
BPC-157 and TB-500 are typically injected subcutaneously into fatty tissue, often near the injury site for localized effects. However, both peptides are systemic, so injecting into the abdomen or thigh is also effective. Rotate injection sites to prevent lipoatrophy or irritation.
Use a 29-31G insulin syringe with a short needle (8mm or 12.7mm). Pinch the skin, insert at a 45-90 degree angle, and inject slowly. Do not rub the area afterward, as this can cause bruising.
Storage and Stability After Reconstitution
Once reconstituted, the blend should be used within 30 days if stored at 2-8°C. Some researchers report stability up to 60 days, but degradation increases over time. Never freeze reconstituted peptides, as ice crystals can damage the peptide structure. Keep the vial away from light and avoid repeated temperature fluctuations.
If you notice cloudiness, particles, or discoloration, discard the vial. These are signs of contamination or degradation.
Sourcing BPC-157 TB-500 Blend in Canada
In Canada, research peptides like BPC-157 and TB-500 are not regulated as prescription drugs, but they are also not approved for human consumption. They are sold as "research chemicals" or "not for human use" by online vendors. Prices for a 5mg/5mg blend vial typically range from CAD $45 to $90, depending on the supplier and purity testing.
When buying in Canada, look for vendors that provide third-party HPLC and mass spectrometry reports. Avoid sellers that market the blend for human use or make medical claims. For a detailed guide on purchasing BPC-157 in Canada, see our article on buying BPC-157 10mg online.
Potential Side Effects and Safety Notes
In research settings, BPC-157 and TB-500 are generally well tolerated. Reported side effects are mild and may include injection site redness, itching, or temporary fatigue. Some users report headaches or dizziness, especially at higher doses. Because TB-500 promotes angiogenesis, it should be avoided in research models with active cancer, as new blood vessel growth could theoretically feed tumors.
BPC-157 has a strong safety profile in animal studies, but long-term human data are lacking. Always consult with a qualified researcher or medical professional before starting any peptide protocol.
Frequently Asked Questions
Can I reconstitute the blend with sterile water instead of bacteriostatic water?
Sterile water can be used if the entire vial will be consumed within 24 hours. For multi-dose use over weeks, bacteriostatic water is required to prevent bacterial growth.
How long does the reconstituted blend last in the fridge?
Most sources recommend using within 30 days for optimal potency. Some peptides may remain stable up to 60 days, but degradation is unpredictable.
Can I mix BPC-157 and TB-500 in the same syringe with other peptides?
Mixing peptides in the same syringe is generally not recommended unless compatibility is confirmed. Different pH levels or preservatives can cause precipitation or degradation.
Is the blend legal in Canada?
Research peptides are legal to possess for laboratory use but not for human consumption. Selling them for human use is prohibited. Always check current regulations before purchasing.
Final Thoughts on Reconstituting the Blend
Reconstituting a BPC-157 and TB-500 5mg/5mg blend is straightforward when you follow sterile technique and accurate math. Start with 2mL of bacteriostatic water for easier dosing, store the vial refrigerated, and use within 30 days. For researchers in Canada, sourcing from a reputable vendor with third-party testing is as important as proper reconstitution.
