BPC-157 Dosage Guide: Protocols & Safety 2026

What Is BPC-157?

BPC-157 (Body Protection Compound-157) is a synthetic 15-amino-acid peptide derived from a protein found in human gastric juice. It has been studied in hundreds of preclinical experiments for its potential to support tissue repair, gut health, and recovery^[1]. For a full overview of its potential effects, see our BPC-157 benefits guide.

Getting the dosage right matters. Too little may not produce meaningful effects. Too much is unlikely to cause harm based on animal safety data (no toxic dose has been identified^[2]), but it wastes product and doesn't necessarily improve outcomes. Working with a physician ensures your dose is tailored to your body and your goals.

Quick-Reference BPC-157 Dosage Chart

This at-a-glance chart summarizes the most commonly referenced BPC-157 dosing protocols. All dosing should be physician-supervised.

Important: These ranges aren't standardized medical guidelines. They represent commonly discussed protocols in physician-supervised peptide therapy and should serve as a starting point for conversations with your provider.

How BPC-157 Dosing Works in Research

In the scientific literature, BPC-157 doses are typically reported in micrograms per kilogram of body weight (mcg/kg). The most commonly studied dose in rodent models is 10 mcg/kg, though doses ranging from 1 mcg/kg to 50 mcg/kg have been used across different studies^[1][3].

Translating animal doses directly to human doses isn't straightforward. Body surface area scaling, metabolic rate differences, and bioavailability all play a role. The FDA's standard interspecies dose conversion uses a body surface area normalization factor - a 10 mcg/kg rat dose roughly converts to a 1.6 mcg/kg human dose using this method^[4]. But most practitioners use higher doses based on clinical experience.

This is why we strongly recommend working with a physician rather than attempting to calculate your own dose from research papers.

What the Research Shows by Dose Level

BPC-157 Dosing by Body Weight

Some physicians use body weight to calculate BPC-157 doses, adapting the research-based 10 mcg/kg model. Here is what that looks like in practice across different weight ranges:

Keep in mind that the 10 mcg/kg figure comes from rodent research and hasn't been validated in human dose-response studies. Many physicians start patients at the low end (5 mcg/kg or a flat 250 mcg) regardless of body weight and adjust based on response over 1-2 weeks.

Tissue-Specific BPC-157 Dosing Protocols

One of BPC-157's unique properties is its systemic healing effect - it appears to promote repair in multiple tissue types simultaneously. But practitioners often tailor the dose, route, and injection site to the primary tissue being targeted^[1][5].

Tendon and Ligament Injuries

Tendons have poor blood supply and heal slowly. BPC-157 has shown particular promise for tendon repair in preclinical models, including Achilles tendon transection and rotator cuff injury studies^[5].

• Dose: 300-500 mcg twice daily
• Route: Subcutaneous injection as close to the injured tendon as practical
• Duration: 6-10 weeks (tendons heal slowly)
• Notes: Peritendinous injection places BPC-157 in the tissue with the poorest natural blood supply, maximizing local concentration

Muscle Injuries and Recovery

BPC-157 promotes muscle fiber regeneration through growth factor upregulation (VEGF, FGF) and angiogenesis at the injury site^[6].

• Dose: 250-500 mcg once or twice daily
• Route: Subcutaneous near the affected muscle group
• Duration: 4-8 weeks
• Notes: Can be combined with physical therapy for optimal results. Some practitioners time the dose pre-rehabilitation to prime the healing response

Gut Health and Intestinal Healing

As a gastric peptide, BPC-157 has particular affinity for the GI tract. Oral administration is often preferred for gut conditions^[7].

• Dose: 250-500 mcg once or twice daily
• Route: Oral (enteric-coated capsule) on an empty stomach
• Duration: 4-8 weeks
• Best for: Leaky gut, IBD flares, NSAID-induced gastric damage, post-antibiotic gut repair
• Notes: BPC-157 is uniquely stable in stomach acid, making oral delivery viable. For severe gut conditions, some providers combine oral and subcutaneous administration

Joint and Cartilage Support

• Dose: 250-500 mcg once or twice daily
• Route: Subcutaneous near the affected joint
• Duration: 8-12 weeks (cartilage has very slow turnover)
• Notes: Often combined with TB-500 for enhanced joint repair. Longer cycles may be needed due to the avascular nature of cartilage

Nerve Injury and Neuropathy

BPC-157 has shown neuroprotective and neuroregenerative properties in animal models of nerve transection and crush injury^[8].

• Dose: 300-500 mcg once or twice daily
• Route: Subcutaneous (systemic - nerve injuries are harder to target locally)
• Duration: 8-12 weeks (nerve regeneration is slow)
• Notes: Nerve healing is among the slowest tissue repair processes. Patience and consistent dosing are important

Bone Fracture Healing

• Dose: 500-800 mcg twice daily
• Route: Subcutaneous near the fracture site
• Duration: 6-10 weeks
• Notes: Higher doses are often used given the metabolic demands of bone repair^[9]

Dosing by Administration Route

Subcutaneous Injection

This is the most common method of BPC-157 administration. Subcutaneous injection delivers the peptide just beneath the skin, where it enters the bloodstream relatively quickly. Most dosing protocols for subcutaneous use fall in the 250-500 mcg range per injection, once or twice daily.

Many practitioners recommend injecting as close to the injury site as possible for localized effects. For example, an individual addressing knee pain might inject subcutaneously near the knee. For systemic effects, the abdomen is a common injection site.

For detailed injection instructions, see our BPC-157 how to inject guide.

Intramuscular Injection

Less commonly used, intramuscular injection delivers BPC-157 deeper into muscle tissue. Dosing is generally similar to subcutaneous administration. This route may be preferred when targeting deep muscle injuries. See our BPC-157 for muscle recovery guide for related information.

Oral Administration

BPC-157 is uniquely stable in stomach acid, making oral administration viable^[7]. Oral dosing is often recommended for gut-related concerns and typically ranges from 250 to 500 mcg, taken on an empty stomach or with minimal food.

Some research suggests that oral BPC-157 may have more pronounced effects on the gastrointestinal tract, while injectable forms may be more effective for musculoskeletal targets. Your physician can help determine the best route for your situation. For gut-specific guidance, see our BPC-157 for gut health guide.

Route Comparison

Reconstitution &. Mixing Guide

BPC-157 typically comes as a lyophilized (freeze-dried) powder that must be reconstituted with bacteriostatic water before use. Accurate reconstitution is important for correct dosing.

Step-by-Step Reconstitution

1. Check the vial label: Confirm the total amount of BPC-157 in the vial (commonly 5 mg or 10 mg)
2. Gather supplies: Bacteriostatic water (BAC water), alcohol swabs, insulin syringes (1 mL / 100 unit)
3. Clean both vial tops: Wipe the BPC-157 vial and BAC water vial with alcohol swabs
4. Draw bacteriostatic water: Using an insulin syringe, draw the desired volume of BAC water (see concentration chart below)
5. Add water slowly: Insert the needle into the BPC-157 vial and let the water run down the inside wall of the vial. Do NOT spray directly onto the powder - this can damage the peptide
6. Gently swirl: Once the water is added, gently swirl (don't shake) until the powder is fully dissolved. The solution should be clear
7. Store properly: Refrigerate at 36-46°F (2-8°C). Use within 28 days of reconstitution

Concentration Chart

Tip: Adding 2 mL of BAC water to a 5 mg vial (creating 2,500 mcg/mL) is the most popular choice - it makes common doses easy to measure and provides a good number of doses per vial.

Storage and Handling

• Before reconstitution: Store lyophilized powder at room temperature or refrigerated. Stable for months
• After reconstitution: Must be refrigerated. Use within 28 days
• Never freeze reconstituted peptide solution
• Protect from light: Store in original box or wrap vial in foil
• Signs of degradation: Discard if solution becomes cloudy, discolored, or contains particles

Cycling and Duration

Most physician-supervised BPC-157 protocols involve defined cycles rather than continuous, indefinite use. Common cycling patterns include:

After completing a cycle, many physicians recommend a break of 2 to 4 weeks before reassessing whether another cycle is warranted. This approach allows the body to consolidate healing gains and helps your physician evaluate the ongoing need for treatment.

There's no established research on the safety or efficacy of long-term, uninterrupted BPC-157 use in humans. Cycling is considered the prudent approach until more data is available.

Timing and Frequency

The research doesn't clearly establish an optimal time of day for BPC-157 administration. But common practices include:

Once Daily Dosing

Typically administered in the morning. This is the simplest protocol and may be sufficient for lower-dose applications and general wellness support.

Twice Daily Dosing (Split Dose)

Morning and evening injections, splitting the total daily dose into two administrations. This approach maintains more consistent peptide levels throughout the day and is often recommended for active injuries or significant therapeutic targets.

Exercise-Timed Dosing

Some individuals time their dose around training sessions. There's no strong research evidence favoring one timing over the other, but some practitioners suggest:

• Pre-workout (30-60 minutes before): May prime the healing response before exercise-induced stress
• Post-workout (within 30 minutes after): May support recovery during the acute healing window

For oral administration, taking BPC-157 on an empty stomach (at least 30 minutes before a meal) is generally recommended to maximize absorption.

Stacking BPC-157 with Other Peptides

Many practitioners combine BPC-157 with complementary peptides to address multiple aspects of healing simultaneously. The most common stacking protocols include:

BPC-157 + TB-500 (Thymosin Beta-4^[1])

This is the most popular peptide stack for injury recovery. BPC-157 and TB-500 work through different but complementary mechanisms^[10]:

• BPC-157: Promotes angiogenesis, growth factor expression, and NO-mediated healing
• TB-500: Regulates actin, promotes cell migration, reduces scar tissue formation

BPC-157 + KPV

Ideal for gut healing protocols where both tissue repair and inflammation reduction are needed:

• BPC-157: 250-500 mcg oral, once or twice daily (tissue repair)
• KPV: 200-500 mcg oral, once daily (anti-inflammatory)

For more on KPV, see our KPV peptide benefits guide.

BPC-157 + GHK-Cu

Used for skin healing, wound recovery, and anti-aging protocols:

• BPC-157: 250-500 mcg subcutaneous, once daily
• GHK-Cu: 1-2 mg subcutaneous, once daily

Important: All stacking protocols should be designed and supervised by a physician. Don't combine peptides without medical guidance.

How to Titrate: Starting Low and Adjusting

Most experienced physicians follow a titration approach - starting with a lower dose and gradually increasing based on response. This minimizes waste and helps identify the minimum effective dose for your condition.

Sample Titration Schedule

Signs that your dose may need adjustment:

• No noticeable improvement after 2 weeks: Dose may need to increase
• Rapid improvement: Current dose is likely appropriate. maintain it
• Side effects (rare): Reduce dose and consult physician

Safety Considerations

BPC-157 has demonstrated an exceptional safety profile in animal studies, with no toxic dose identified even at doses 1,000 times the therapeutic range^[2]. But dosing decisions should always be made with a physician because:

• Animal dose-response data doesn't translate directly to humans
• Individual factors (body composition, health status, medications) affect how you respond
• Quality and purity of the product matter significantly - only use pharmaceutical-grade BPC-157 from licensed compounding pharmacies
• Proper reconstitution and storage are important for safety and efficacy

Who Should NOT Use BPC-157

• Pregnant or breastfeeding women (insufficient safety data)
• Individuals with active cancer (BPC-157 promotes angiogenesis, which could theoretically support tumor growth)
• Children under 18 (no pediatric dosing established)
• Anyone with a known allergy to the peptide or its components

Frequently Asked Questions

What is the standard BPC-157 dosage?

There's no officially standardized dose. Research commonly references 10 mcg/kg body weight in animal models. In clinical practice, human doses typically range from 200 to 800 mcg per day, depending on the individual and their goals. Your physician will determine the right dose for you.

How often should I take BPC-157?

Most protocols involve once or twice daily administration. Once daily is common for lower doses and general wellness, while twice daily (splitting the total dose) is often used for active injuries and more targeted therapeutic goals.

Can I take too much BPC-157?

Animal studies haven't identified a toxic dose, which is reassuring. But taking more than needed doesn't necessarily produce better results and wastes product. Working with a physician ensures you use the optimal amount for your goals.

Should I inject BPC-157 near the injury or in my stomach?

For musculoskeletal injuries, injecting subcutaneously as close to the injury site as practical is generally recommended to maximize local concentration. For gut health, oral administration targets the GI tract directly. For systemic effects, abdominal subcutaneous injection is standard.

Should I take BPC-157 with food?

For injectable forms, food timing isn't a significant concern. For oral BPC-157, taking it on an empty stomach (at least 30 minutes before eating) is generally recommended for better absorption.

How long should a BPC-157 cycle last?

Most protocols range from 4 to 12 weeks, followed by a 2-4 week break. The duration depends on the condition being addressed and how you respond. Tendon and nerve injuries often require longer cycles (8-12 weeks) due to slower tissue healing rates.

Can I stack BPC-157 with TB-500?

Yes. BPC-157 and TB-500 are the most commonly combined peptides for injury recovery. They work through different mechanisms and appear to have combined effects. Your physician can design a stacking protocol tailored to your situation.

How much bacteriostatic water should I add to my BPC-157 vial?

For a 5 mg vial, adding 2 mL of bacteriostatic water creates a concentration of 2,500 mcg/mL - the most popular choice for easy dose measurement. See the reconstitution section above for a full concentration chart.

Does BPC-157 need to be refrigerated?

Before reconstitution, lyophilized BPC-157 is stable at room temperature. After reconstitution with bacteriostatic water, it must be refrigerated (36-46°F / 2-8°C) and used within 28 days.
