/ mechanism

How they work

BPC-157

Upregulates HGF (hepatocyte growth factor) and FGF signaling. Increases fibroblast proliferation and migration. Promotes angiogenesis.

TB-500

Increases β-actin polymerization. Promotes cell migration and differentiation. Anti-inflammatory via IL-10 upregulation.

/ research dosing

Protocols compared

BPC-157
Range: 250-500 mcg/day (most common: 500 mcg/day split AM/PM)
Frequency: Daily, often split 250mcg AM + 250mcg PM
Route: Subcutaneous (subQ) near injury site; oral viable for gut research
Research literature scales from 10mcg/kg in animal models. Subcutaneous injection near injury site shows higher local effect. For gut/GI research, oral dosing is stable due to gastric acid resistance. Huberman protocol cites 300-500 mcg, 2-3x weekly for 8 weeks.
TB-500
Range: 2.5-5 mg/week (loading) → 2-2.5 mg/week (maintenance)
Frequency: 1-2x weekly during loading; weekly thereafter
Route: Subcutaneous
Often stacked with BPC-157 in 1:1 ratio for recovery research. Loading phase builds tissue concentration; maintenance preserves effect. Animal models support faster tendon and ligament healing.

/ which to pick

The honest verdict

Pick BPC-157 if: Strong standalone compound. Research-backed for tissue and tendon repair as a single agent.

Pick TB-500 if: Effective standalone for tissue repair research. Strong data on solo administration.
