It is formed from three amino acids, viz

Supporting this extended regeneration phase with compounds like BPC 157 peptide may result in more complete, resilient repairs that are less likely to re-injure

Hypoxia-inducible factor-1 (HIF-1) but not HIF-2 is essential for hypoxic induction of collagen prolyl 4-hydroxylases in primary newborn mouse epiphyseal growth plate chondrocytes

But both can be prescribed for other off-label uses
