What is BPC-157?
BPC-157 (Body Protection Compound-157) is a synthetic peptide consisting of 15 amino acids derived from a protective protein naturally found in human gastric juice. It has become one of the most discussed and researched peptides in the healing and recovery space, with over 100 published preclinical studies examining its effects on tissue repair.
Unlike many peptides that degrade quickly in the body, BPC-157 is remarkably stable in gastric acid, which is unusual for a peptide of its size. This stability is part of what makes it so interesting to researchers and the biohacking community alike.
Why BPC-157 Is So Popular
BPC-157 has gained a massive following because of the breadth of its researched applications:
- Tendon and Ligament Repair: The most extensively studied application, with multiple animal models showing accelerated healing
- Muscle Injury Recovery: Research shows improved healing of torn and damaged muscle tissue
- Gut Health and Protection: As a gastric peptide derivative, it has strong research backing for GI protection and ulcer healing
- Joint Support: Studies suggest benefits for cartilage and joint tissue repair
- Anti-Inflammatory Effects: Demonstrated reduction of inflammatory markers in multiple models
- Neuroprotection: Emerging research on nerve damage repair and neurological protection
How BPC-157 Works
BPC-157 operates through several mechanisms that work together to accelerate healing:
- Growth Factor Upregulation: Increases expression of growth hormone receptors and growth factors (EGF, FGF, HGF) involved in tissue repair
- Angiogenesis: Promotes the formation of new blood vessels, bringing nutrients and oxygen to damaged tissue
- Nitric Oxide System: Interacts with the NO system to regulate blood flow and inflammation at injury sites
- Collagen Production: Supports collagen synthesis, critical for tendon, ligament, and skin repair
- Actin Production: Increases actin at the gene level, telling cells to produce more structural building materials
- Anti-Inflammatory Pathways: Reduces pro-inflammatory cytokines while supporting healing cascades
Half-Life
BPC-157 has a relatively short half-life of less than 30 minutes following injection, which is why split dosing (twice daily) is commonly discussed in protocol guides. Despite the short half-life, its effects on gene expression and healing cascades persist well beyond the active window of the peptide itself.
Reconstitution Guide
BPC-157 ships as a lyophilized (freeze-dried) powder and must be reconstituted before use. Getting this step right is critical.
What You Need
- BPC-157 lyophilized powder (typically 5mg or 10mg vials)
- Bacteriostatic water (BAC water with 0.9% benzyl alcohol)
- Sterile insulin syringes (U-100)
- Alcohol swabs
Reconstitution Steps
For a 5mg vial: Add 5mL of bacteriostatic water for a concentration of 1mg/mL. At this concentration, 0.25mL (25 units on a U-100 syringe) equals 250mcg of BPC-157.
For a 10mg vial: Add 3mL of bacteriostatic water for a concentration of 3.33mg/mL. Alternatively, add 10mL for an easier 1mg/mL concentration where 0.25mL = 250mcg.
Critical Reconstitution Tips
- Never shake the vial. Direct the stream of BAC water down the side of the glass, not directly onto the powder
- Let it rest. After adding water, let the vial sit for 10-20 minutes. The powder should dissolve on its own
- Gently roll if needed. If particles remain after resting, gently roll the vial between your palms. Never shake or tap
- Check clarity. A properly reconstituted, high-purity peptide should be perfectly clear. Cloudiness or floating particles indicate contamination or poor quality product — do not use it
- Use BAC water, not plain sterile water. The benzyl alcohol preservative in BAC water prevents bacterial growth and gives you a 4-week shelf life. Plain sterile water has no preservative
Dosing Protocols
BPC-157 dosing is typically calculated based on body weight in micrograms (mcg) per kilogram (kg). Research protocols commonly use 2-10 mcg/kg per day.
Beginner Protocol
- Dose: 200-250mcg per injection
- Frequency: Twice daily (morning and evening, 12 hours apart)
- Total Daily Dose: 400-500mcg
- Duration: 2-4 weeks
- Best for: Minor injuries, general recovery, first-time users
Standard Protocol
- Dose: 300-400mcg per injection
- Frequency: Twice daily
- Total Daily Dose: 600-800mcg
- Duration: 4-6 weeks
- Best for: Moderate injuries, tendon/ligament issues, chronic pain
Advanced Protocol
- Dose: 500mcg per injection
- Frequency: Twice daily
- Total Daily Dose: 1000mcg (1mg)
- Duration: 4-8 weeks
- Best for: Severe injuries, post-surgical recovery, stubborn chronic conditions
Cycling Recommendations
- Standard Healing Cycle: 6-8 weeks on, 2-4 weeks off
- Acute Injury Cycle: 4-6 weeks on, 2 weeks off
- Maintenance Cycle: 4 weeks on, 4 weeks off
- Cycling helps prevent potential tolerance and allows natural healing processes to integrate with peptide-supported repair
Administration Methods
Subcutaneous Injection (Most Common)
The preferred method for most users. Inject into the fatty tissue of the abdomen, thigh, or upper arm.
- Injection site strategy: For systemic effects, abdominal subcutaneous injection works well. For localized injuries, inject as close to the injury site as safely possible
- Rotate injection sites to prevent irritation and tissue hardening
- Use a fresh sterile insulin syringe for every injection
- Inject slowly, wait a few seconds before withdrawing the needle
- Timing: 30-60 minutes before training for injury prevention, or immediately post-workout for recovery
Intramuscular Injection
Less common but used for deeper tissue injuries. Follows the same dosing but delivers the peptide deeper into muscle tissue.
Oral Administration
BPC-157 is unique among peptides in that it retains some activity when taken orally, due to its gastric acid stability. Oral BPC-157 is primarily useful for gut-related issues (ulcers, IBD, GI inflammation) but provides less systemic bioavailability for musculoskeletal injuries.
The Wolverine Stack: BPC-157 + TB-500
The combination of BPC-157 and TB-500 (a synthetic fragment of thymosin beta-4) has become one of the most popular peptide stacks in the recovery community, nicknamed the "Wolverine Stack" for its reported healing capabilities.
Why They Work Together
The two peptides are complementary:
- BPC-157 increases actin production at the gene level — it tells cells to make more building materials and promotes local healing at the injection site
- TB-500 is an actin-binding protein that helps organize and utilize that actin where it's needed — it acts as the logistics system and provides systemic recovery support
BPC-157 excels at local, targeted healing near the injection site, while TB-500 provides broader systemic support. Together, practitioners report healing roughly 50% faster than either peptide alone.
Wolverine Stack Protocol
- BPC-157: 250-500mcg twice daily (subcutaneous, near injury site)
- TB-500: 2-10mg per week, divided into 2-3 injections (subcutaneous)
- Cycle: 4-6 weeks on, 2-3 weeks off
- Support: Combine with proper hydration, rest, and light physical therapy
Important Note on Stacking
Do not mix BPC-157 and TB-500 in the same syringe or vial. Draw and inject them separately, even if injecting at the same time.
Storage Guidelines
Proper storage is essential to maintain peptide integrity:
Lyophilized (Powder) Form
- Store at -20°C (-4°F) for long-term storage
- Keep in dry, dark conditions
- Minimize moisture exposure
- Properly stored lyophilized BPC-157 can remain stable for years
Reconstituted (Liquid) Form
- Refrigerate at 2-8°C (36-46°F)
- When reconstituted with BAC water, stable for approximately 30 days
- Never freeze reconstituted peptide — the freeze-thaw cycle damages the peptide structure
- Minimize the number of times you pierce the vial stopper
- If preparing multiple doses ahead of time, pre-load syringes and refrigerate them
What the Research Says
Preclinical Evidence (Strong)
A 2025 systematic review identified 36 studies on BPC-157 in orthopedic and sports medicine contexts (35 preclinical, 1 clinical). Key findings include:
- Enhanced growth hormone receptor expression
- Activation of cell growth and angiogenesis pathways
- Reduction of inflammatory cytokines
- Improved functional, structural, and biomechanical outcomes in muscle, tendon, ligament, and bone injury models
Clinical Evidence (Limited but Growing)
- A retrospective study of 12 patients receiving intraarticular BPC-157 for chronic knee pain found 7 reported pain relief lasting over 6 months
- A 2025 IV safety study in healthy adults found doses up to 20mg well-tolerated with no adverse events
- BPC-157 follows linear pharmacokinetics after single and repeat dosing
The Angiogenesis Question
A common concern is whether BPC-157's promotion of new blood vessel growth could be problematic. However, preclinical data actually suggests BPC-157 may inhibit uncontrolled cell proliferation — one study showed it suppressed the VEGF pathway in melanoma cells, suggesting it promotes organized healing rather than unchecked growth.
Regulatory Status and Safety
FDA Classification
In 2023, the FDA classified BPC-157 as a Category 2 bulk drug substance, meaning it cannot be compounded by commercial pharmaceutical companies. There is no FDA-approved indication for BPC-157. It is commonly sold as a "research chemical" which is not subject to the same FDA regulations as pharmaceuticals.
WADA Status
BPC-157 is banned by WADA for competitive athletes. If you compete in tested sports, be aware that BPC-157 is a prohibited substance.
Reported Side Effects
Side effects are generally mild and uncommon but can include:
- Nausea (typically with higher doses)
- Headaches
- Dizziness
- Injection site reactions (redness, minor swelling)
Sourcing Quality BPC-157
The unregulated nature of the peptide market makes quality verification essential:

Frequently Asked Questions
How should I store BPC-157?
Lyophilized powder at -20°C long-term. Once reconstituted with BAC water, refrigerate at 2-8°C and use within 30 days. Never freeze reconstituted peptide.
What's the difference between subcutaneous and intramuscular injection?
Subcutaneous goes into fatty tissue just below the skin (easiest, most common). Intramuscular goes deeper into muscle tissue. For most healing applications, subcutaneous near the injury site is preferred.
Can I take BPC-157 orally?
Yes, BPC-157 is stable in gastric acid unlike most peptides. Oral administration is primarily effective for gut-related issues. For musculoskeletal healing, injection provides significantly better bioavailability.
How quickly will I see results?
Many users report reduced pain and improved mobility within the first 1-2 weeks. Structural healing of tendons and ligaments typically shows meaningful progress over 4-8 weeks.
Is BPC-157 safe to stack with TB-500?
The BPC-157 + TB-500 "Wolverine Stack" is one of the most commonly used peptide combinations. They work through complementary mechanisms. Do not mix them in the same syringe — draw and inject separately.
Does BPC-157 cause cancer?
This is a common concern due to its angiogenic properties. However, preclinical research suggests BPC-157 actually inhibits uncontrolled cell proliferation. No studies have linked BPC-157 to cancer promotion.
How long should I cycle BPC-157?
Standard healing cycles run 6-8 weeks on, 2-4 weeks off. For acute injuries, 4-6 weeks on with a 2-week break. Cycling prevents potential tolerance buildup.
