About

MI-31 is a short research peptide studied for its effects on matrix metalloproteinase (MMP) inhibition and tissue remodeling. It is being investigated for applications in aging skin, fibrosis prevention, and connective tissue maintenance.

Mechanism of Action

Inhibits select matrix metalloproteinases (MMPs) that degrade collagen and elastin in aging tissue, preserving extracellular matrix integrity.

Primary Benefits

  • Extracellular matrix preservation
  • Anti-fibrotic properties
  • Skin integrity support
  • Connective tissue protection

Side Effects & Considerations

  • Limited data available
  • Injection site reactions

Stacking Guide

Synergistic Stacks

GHK-Cu

GHK-Cu activates collagen synthesis while MI-31 prevents its degradation — complementary matrix protection.

BPC-157

BPC-157 drives new tissue formation; MI-31 prevents premature breakdown of the new matrix.

Redundant / Avoid Together
