BPC-157 vs TB-500: Which Healing Peptide is Better?
Compare BPC-157 and TB-500 for injury recovery. We break down mechanisms, effectiveness, side effects, and when to use each peptide.
BPC-157 and TB-500 are two of the most popular peptides for injury recovery and tissue healing. While both aim to accelerate healing, they work through different mechanisms and may be better suited for different types of injuries.
Quick Comparison
| Category | BPC-157 | TB-500 |
|---|---|---|
| Primary Mechanism | Nitric oxide modulation, angiogenesis | Cell migration, actin production |
| Best For | Tendon/ligament injuries, gut healing | Muscle injuries, systemic healing |
| Administration | Subcutaneous near injury site | Subcutaneous anywhere |
| FDA Status | Category 2 (banned from compounding) | Category 2 (banned from compounding) |
| Typical Dose | 250-500 mcg/day | 2.5-5 mg twice weekly |
| Onset of Effects | 1-2 weeks | 2-4 weeks |
| Research Quality | 100+ animal studies, no human trials | Moderate animal data, limited studies |
Understanding the Mechanisms
BPC-157 (Body Protection Compound-157) is a synthetic peptide derived from a protein found in gastric juice. It works primarily through nitric oxide pathways and promotes angiogenesis—the formation of new blood vessels. This localized mechanism makes it particularly effective when injected near the injury site. TB-500 (Thymosin Beta-4) is a naturally occurring peptide that promotes cell migration and differentiation. It upregulates actin production, which is essential for cell structure and movement. Unlike BPC-157, TB-500 works systemically throughout the body.
Which Should You Choose?
For localized tendon, ligament, or joint injuries, BPC-157 is often preferred due to its targeted action when injected near the injury site. For muscle injuries or when seeking overall tissue repair and recovery, TB-500 may be more appropriate. Many users combine both peptides—using BPC-157 for targeted healing and TB-500 for systemic support.

Frequently Asked Questions
Can you stack BPC-157 and TB-500 together?
Yes, many users combine BPC-157 and TB-500 for synergistic effects. BPC-157 works locally near the injection site while TB-500 provides systemic healing benefits. This combination is often called the "Wolverine stack" in biohacking communities.
Which is better for tendon injuries, BPC-157 or TB-500?
BPC-157 is generally considered more effective for tendon and ligament injuries based on available research. It promotes angiogenesis (new blood vessel formation) directly at the injury site. TB-500 may complement this by supporting overall tissue repair.
Are BPC-157 and TB-500 legal to buy?
Both peptides exist in a legal gray area. As of October 2023, the FDA placed both on the Category 2 list, prohibiting compounding pharmacies from producing them. However, they can still be purchased as "research chemicals" from various vendors.
