The Tendon Repair Protocol
Three peptides, three mechanisms, one goal
The most research-backed combination for tendon and ligament tissue repair studies. Each compound targets a different stage of the repair process.
How this works
BPC-157 upregulates HGF and FGF growth factor signaling in fibroblasts. TB-500 increases β-actin polymerization, enabling faster cell migration to injury sites. GHK-Cu upregulates collagen synthesis (types I, III, IV) and inhibits matrix metalloproteinase, stabilizing new tissue.
The synergy
These three compounds hit different cellular processes: TB-500 mobilizes repair cells to the injury site, BPC-157 signals them to proliferate via growth factors, and GHK-Cu stabilizes the new collagen they produce. Animal models show 40%+ faster repair vs single-compound protocols.
How researchers run it
Each compound, explained
BPC-157
Pentadecapeptide derived from gastric juice protein. Extensively researched for tissue repair.
Upregulates HGF (hepatocyte growth factor) and FGF signaling. Increases fibroblast proliferation and migration. Promotes angiogenesis.
Generally well-tolerated. Rare reports of mild GI discomfort at high doses.
TB-500
Synthetic analog of naturally-occurring thymosin beta-4. Present in nearly all human cells.
Increases β-actin polymerization. Promotes cell migration and differentiation. Anti-inflammatory via IL-10 upregulation.
Minimal. Some report mild headache. Very low toxicity profile.
GHK-Cu
Natural copper complex first isolated in 1973. Extensively studied for skin, hair, and collagen applications.
Upregulates collagen I, III, IV synthesis. Inhibits matrix metalloproteinase (MMP). Promotes tissue remodeling.
Topical: minimal. Systemic: occasional mild blue discoloration at injection site.
