BPC-157 History & Discovery

The Discovery: 1993

BPC-157 was first described in scientific literature in 1993 by a team of Croatian researchers led by Dr. Predrag Sikiric at the University of Zagreb School of Medicine.

The Original Discovery

The research team was investigating protective proteins found naturally in human gastric (stomach) juice. They identified a larger protein compound called Body Protection Compound (BPC) that appeared to have cytoprotective properties—the ability to protect cells from damage.

Key Discovery Points

• Source: Isolated from human gastric juice
• Function: Part of the stomach's natural defense mechanisms
• Purpose: Protects gastric mucosa from damage
• Innovation: Researchers synthesized a stable 15-amino acid fragment

Why Create BPC-157?

The natural BPC protein had limitations for therapeutic use:

• Large and complex structure
• Unstable outside the stomach environment
• Difficult to synthesize and administer
• Rapidly degraded by enzymes

The Croatian team created BPC-157 as a synthetic pentadecapeptide (15 amino acids) that retained the protective properties of the parent compound while being:

• Chemically stable at room temperature
• Resistant to enzymatic degradation
• Easier to synthesize and produce
• Effective through multiple administration routes

Early Research (1993-2000)

The first decade of BPC-157 research focused primarily on gastrointestinal applications, reflecting its origins from gastric juice.

Initial Studies

Gastric Protection (1993-1995)

• Demonstrated protection against alcohol-induced gastric lesions
• Showed effectiveness against NSAID-induced ulcers
• Proved stable in gastric acid (unusual for peptides)
• Worked through different mechanisms than traditional anti-ulcer drugs

Expanding Applications (1996-2000)

Research began exploring BPC-157 beyond the gastrointestinal tract:

• 1997: First studies on inflammatory bowel disease models
• 1998: Initial research on wound healing properties
• 1999: Early investigations into neurological effects
• 2000: First studies on musculoskeletal healing

Key Researchers

The primary research group at University of Zagreb included:

• Dr. Predrag Sikiric: Lead researcher and primary investigator
• Dr. Sven Seiwerth: Co-investigator and collaborator
• Multiple graduate students and postdocs who contributed to expanding research
