BPC-157 vs TB-500

Which healing peptide is right for your recovery?

Last updated: 2024-12-05

BPC-157

Gastric-derived peptide. 15 amino acids. Studied for gut, tendon, ligament, and wound healing. Often injected locally.

TB-500

Synthetic thymosin beta-4 fragment. 43 amino acids. Systemic tissue repair effects. Promotes cell migration and angiogenesis.

Side-by-Side Comparison

Category
BPC-157
TB-500
Primary Mechanism
Growth factor upregulation

Stimulates growth hormone receptors, promotes nitric oxide, increases angiogenesis. More localized effects.

Cell migration & actin regulation

Promotes cell movement to injury sites, regulates actin (cell skeleton), reduces inflammation. Systemic effects.

Best Used For
Gut + localized injuries

Strong preclinical data for gut healing, tendon/ligament repair, NSAID-induced damage. Often injected near injury site.

Systemic/widespread injuries

Cardiac tissue repair in animal models, flexibility, muscle adhesions. Works systemically—injection location doesn't matter.

Administration
Local injection OR oral

Subcutaneous near injury for musculoskeletal issues. Oral (capsule) for gut-specific healing. Oral is the "stable" arginine salt form.

Injection (any location)

Subcutaneous injection—location doesn't matter since it's systemic. Typically stomach or thigh. Not effective orally.

Dosing Protocol
250-500mcg/day

Common: 250-500mcg once or twice daily. 4-8 week cycles. Split doses for sustained levels. Lower total dose than TB-500.

2-2.5mg 2x/week (loading)

Loading phase: 2-2.5mg twice weekly for 4-6 weeks. Maintenance: weekly or bi-weekly. Higher total peptide amounts.

Preclinical Evidence
Extensive (hundreds of studies)

Robust animal data across many tissue types: gut, tendon, ligament, muscle, nerve, bone. Consistent positive findings.

Moderate

Good animal data, especially for cardiac and wound healing. Less extensive than BPC-157 for musculoskeletal specifically.

Human Evidence
Extremely limited

One small knee study (7/12 patients improved). No large RCTs. Virtually all evidence is preclinical.

Phase I safety data only

Well-tolerated up to 1260mg IV in Phase I. Some trials for dry eye/skin conditions. No musculoskeletal RCTs.

Cost
$30-100/month

Relatively affordable. 5-10mg vials typically $50-100. Oral forms may be slightly more expensive.

$75-200/month

More expensive due to higher doses required. 5mg vials typically $40-80 each.

Regulatory Status
Not approved, WADA banned

Research chemical only. Not FDA-approved for any indication. Banned in tested athletics.

Not approved, WADA banned

Same status as BPC-157. Both are unregulated and banned in competitive sports.

Safety Profile
Generally well-tolerated

No serious adverse events reported in available data. Theoretical cancer concern due to angiogenesis. Long-term effects unknown.

Phase I showed good tolerance

Safety study showed no serious adverse events. Same theoretical concerns about promoting cell growth/migration.

The Bottom Line

BPC-157 and TB-500 are the two most popular research peptides for injury recovery, but they work differently and may be better suited for different situations.

**BPC-157** has more preclinical research behind it (hundreds of studies) and is often preferred for gut healing and localized injuries where you can inject near the problem area. The oral form makes it uniquely suited for gut-specific issues.

**TB-500** works systemically—it doesn't matter where you inject it. This makes it potentially better for widespread inflammation, flexibility issues, or when you have multiple injury sites. It may also have benefits for cardiac tissue that BPC-157 doesn't.

Many people in the biohacking community use both together (the "healing stack"), believing they have complementary mechanisms. However, it's important to remember that neither has robust human clinical trial data, and both are unregulated research chemicals with unknown long-term effects.

Which Is Right for You?

Consider BPC-157 if...
  • You have gut issues (IBD, leaky gut, NSAID damage)
  • You have a localized injury where you can inject nearby
  • You prefer oral administration (for gut issues)
  • You want the peptide with more preclinical research
  • Budget is a concern (it's cheaper)
  • You're targeting a specific tendon or ligament issue
Consider TB-500 if...
  • You have multiple injury sites or widespread inflammation
  • You want systemic effects without worrying about injection location
  • Flexibility and muscle adhesions are a concern
  • You've tried BPC-157 without desired results
  • You prefer less frequent dosing (2x weekly vs daily)
  • You want to combine it with BPC-157 for a "stack" approach
