Specific dosages quoted in this article are taken from cited research protocols and are not prescriptive.
To calculate your BPC-157 and TB-500 blend dosage for tissue repair, use a typical research dose of 250–500 mcg of each peptide once or twice daily, adjusting based on injury severity and body weight. The exact amount you draw into a syringe depends on how you reconstitute the blend, which we will detail below. This guide provides a simple calculator approach, reconstitution steps, and dosing protocols so you can administer the blend accurately.
What Is the BPC-157 and TB-500 Blend?
The blend combines two research peptides known for their tissue repair properties. BPC-157, a pentadecapeptide derived from gastric juice, promotes angiogenesis and accelerates healing of tendons, ligaments, and the gut. TB-500, a synthetic fragment of thymosin beta-4, upregulates actin and cell migration, aiding muscle repair and reducing inflammation. Together, they are often studied for synergistic effects on recovery from injuries like muscle tears, ligament sprains, and post-surgical healing.
Researchers frequently purchase a pre-mixed vial containing equal amounts of each peptide, such as 5 mg BPC-157 and 5 mg TB-500, or 10 mg of each. This blend simplifies administration compared to injecting two separate peptides. Before diving into the dosage calculator, it is essential to understand reconstitution, as the concentration determines how much liquid to draw.
How to Reconstitute the BPC-157 TB-500 Blend
Reconstitution involves adding bacteriostatic water to the lyophilized powder to create an injectable solution. The amount of water you add dictates the concentration, which directly impacts your dosage calculations. A common approach is to add 2 mL of bacteriostatic water to a vial containing 5 mg of each peptide. This yields a concentration of 2.5 mg/mL for each peptide, meaning every 0.1 mL (10 units on an insulin syringe) contains 250 mcg of BPC-157 and 250 mcg of TB-500.
If your vial contains 10 mg of each peptide, adding 2 mL of water gives 5 mg/mL per peptide, so 0.1 mL contains 500 mcg of each. Always use a sterile syringe and gently swirl the vial to dissolve the powder; do not shake vigorously as this can damage the peptides. Store the reconstituted solution in the refrigerator and use within 30 days for optimal stability.

Using the Dosage Calculator
The dosage calculator is straightforward: you need to know the concentration of your reconstituted blend and your desired dose in micrograms. The formula is:
Volume to inject (mL) = Desired dose (mcg) / Concentration (mcg/mL)
For example, if you reconstituted 5 mg/5 mg with 2 mL of water, the concentration is 2500 mcg/mL for each peptide. To get a 250 mcg dose of each, you inject 0.1 mL (250 / 2500 = 0.1). For a 500 mcg dose, inject 0.2 mL. Most insulin syringes are marked in units, where 1 unit = 0.01 mL. So 0.1 mL equals 10 units, and 0.2 mL equals 20 units.
Here is a quick reference table for common concentrations:
- 5 mg/5 mg vial + 2 mL water: 250 mcg = 0.1 mL (10 units), 500 mcg = 0.2 mL (20 units)
- 10 mg/10 mg vial + 2 mL water: 250 mcg = 0.05 mL (5 units), 500 mcg = 0.1 mL (10 units)
- 10 mg/10 mg vial + 4 mL water: 250 mcg = 0.1 mL (10 units), 500 mcg = 0.2 mL (20 units)
Always double-check your math and use a peptide calculator app if unsure. The key is to ensure you are drawing the correct amount for both peptides simultaneously, since they are mixed in equal proportions.
Standard BPC-157 TB-500 Blend Dosage for Tissue Repair
Research protocols commonly use a daily dose of 250–500 mcg of each peptide, administered once or twice daily. For acute injuries, a typical cycle is 250 mcg twice daily for the first two weeks, then once daily for another two to four weeks. For chronic conditions or post-surgery, some protocols extend to 500 mcg twice daily for four to six weeks, followed by a maintenance phase.
The total daily dose of the blend should not exceed 1000 mcg of each peptide in most studies, as higher doses have not shown additional benefits and may increase side effect risks. Body weight can also guide dosing: a rough guideline is 5–10 mcg per kg of body weight per dose. For a 70 kg individual, that is 350–700 mcg per dose. Adjust within the 250–500 mcg range accordingly.
It is crucial to cycle the blend to prevent receptor desensitization. A common cycle is 4–6 weeks on, followed by 2–4 weeks off. Some researchers use a 5-day on, 2-day off schedule to mimic natural healing rhythms. Always start at the lower end of the dosage range to assess tolerance.
Injection Timing and Site Selection
Inject the blend subcutaneously or intramuscularly near the injury site for localized effects, though systemic benefits occur regardless of injection location. For gut healing or general recovery, subcutaneous injection into the abdomen is standard. Rotate injection sites to avoid irritation. The best times are morning and evening, ideally on an empty stomach or at least 30 minutes before meals to enhance absorption.
For muscle tears, injecting as close to the injury as possible is preferred, but avoid injecting directly into inflamed or swollen tissue. Use a small insulin syringe with a 30-gauge needle for comfort. The blend is typically well-tolerated, with mild injection site reactions being the most common side effect.
Calculating Weekly and Cycle Totals
To plan your cycle, calculate the total amount of each peptide you will use. For a 250 mcg twice-daily protocol, that is 500 mcg per day, or 3.5 mg per week of each peptide. A 5 mg/5 mg vial would last about 10 days at this dose. For a 500 mcg twice-daily protocol, you use 1 mg per day, or 7 mg per week, so a 10 mg/10 mg vial lasts about 10 days. Always order enough vials to complete your cycle without interruption.

Factors That Influence Dosage
Several factors can affect the optimal dosage. Age and metabolic rate play a role; older subjects may require slightly higher doses due to reduced endogenous healing factors. The severity and type of injury also matter: tendon and ligament injuries often respond to lower doses over longer periods, while muscle tears may need higher initial doses. Concurrent use of other peptides or supplements, such as growth hormone secretagogues, can enhance effects and may allow for lower doses of the blend.
Individual response varies, so monitor healing progress and adjust accordingly. If no improvement is seen after two weeks, consider increasing the dose within the safe range or reassess the injury. Keep a log of dosages, injection times, and subjective recovery markers to fine-tune your protocol.
Safety and Side Effects
In research settings, the BPC-157 and TB-500 blend is considered safe with minimal side effects. Reported effects include temporary redness or swelling at the injection site, mild headaches, or nausea, which usually resolve quickly. There are no known long-term adverse effects, but long-term human data is limited. Avoid use in subjects with active cancer, as both peptides promote angiogenesis, which could theoretically accelerate tumor growth.
Always source peptides from reputable vendors that provide third-party purity testing. Contaminated or impure products can cause serious reactions. Store the blend properly and never share vials or syringes. If any severe reaction occurs, discontinue use immediately.
Combining with Other Peptides for Enhanced Repair
Some researchers stack the BPC-157/TB-500 blend with other peptides to amplify tissue repair. Growth hormone secretagogues like Ipamorelin or CJC-1295 can boost growth hormone levels, supporting tissue regeneration. For cognitive benefits during recovery, nootropics like Selank or Semax may be added. However, always research interactions and start with one new compound at a time.

Practical Example: Calculating a 4-Week Cycle
Let's walk through a sample calculation. Suppose you have a 10 mg/10 mg blend vial and reconstitute it with 2 mL of bacteriostatic water. You plan a protocol of 500 mcg of each peptide twice daily for 4 weeks. Your daily dose is 1000 mcg (1 mg) of each. Each vial contains 10 mg, so one vial lasts 10 days. For 28 days, you need 3 vials (with some leftover). Each injection is 0.1 mL (10 units) because the concentration is 5 mg/mL (5000 mcg/mL), and 500 mcg / 5000 mcg/mL = 0.1 mL.
If you instead use a 5 mg/5 mg vial with 2 mL water, the concentration is 2.5 mg/mL. For a 500 mcg dose, you inject 0.2 mL (20 units). One vial lasts 5 days at 1 mg daily, so you would need 6 vials for 4 weeks. Always calculate based
