BPC-157 vs TB-500

BPC-157 and TB-500 are the two most popular peptides for healing and tissue repair. BPC-157 excels at localized healing — especially tendons, ligaments, and gut tissue — through angiogenesis and growth hormone receptor upregulation. TB-500 provides systemic healing via actin upregulation and cell migration, making it better for widespread or hard-to-reach injuries. Many users stack both for synergistic results.

When to Choose Each

Choose BPC-157

Tendon/ligament injuries, gut healing (IBS, leaky gut, ulcers), NSAID damage recovery, localized muscle tears

Choose TB-500

Widespread or chronic injuries, cardiac repair, joint flexibility, hair thinning, systemic inflammation

Verdict

For targeted healing of a specific injury (torn tendon, gut issues, localized muscle damage), BPC-157 is the stronger first choice due to its localized action and oral bioavailability. For systemic healing, widespread inflammation, cardiac support, or injuries in hard-to-reach areas, TB-500 is preferred. The optimal approach for serious injuries is stacking both peptides — BPC-157 for local repair and TB-500 for systemic support — which is the most common protocol among experienced users.

Frequently Asked Questions

Can I stack BPC-157 and TB-500 together?
Yes — this is the most popular healing peptide stack. They work through complementary mechanisms (BPC-157 for local angiogenesis, TB-500 for systemic actin/cell migration). A common protocol is BPC-157 250 mcg 2× daily + TB-500 2.5 mg 2× weekly for 4–6 weeks.
Which is better for tendon injuries?
BPC-157 has stronger evidence for tendon-specific healing. It directly upregulates growth hormone receptors in tendon fibroblasts and promotes blood vessel formation at the injury site. Inject subcutaneously near the injured tendon for best results.
Which is better for gut issues?
BPC-157 by far. It is derived from gastric juice, is stable in stomach acid (so it can be taken orally), and has extensive research for healing IBS, leaky gut, ulcers, and NSAID-induced gut damage. TB-500 has minimal evidence for gut-specific benefits.
Do I need a prescription for BPC-157 or TB-500?
Neither peptide is FDA-approved for human use. They are available as research chemicals from peptide vendors. Some telehealth clinics and compounding pharmacies offer them under physician supervision. Regulatory status varies by country.
How long does a typical BPC-157 or TB-500 cycle last?
Common protocols reported in the research community typically run 4 to 6 weeks for both peptides, though some practitioners extend to 8 weeks for chronic or severe injuries. BPC-157 is usually dosed daily due to its shorter half-life, while TB-500 is commonly administered twice weekly. Some users cycle off for 2 to 4 weeks before repeating if needed. The appropriate duration may depend on injury severity, response, and other individual factors. Consulting a healthcare provider is recommended to determine the right protocol for your situation.
