What is BPC-157 and what is IGF-1 LR3?
BPC-157 is classified as Synthetic pentadecapeptide · tissue-repair research; IGF-1 LR3 as Recombinant IGF-1 analog polypeptide. Both profiles below cover scientific identity only — what the molecule is and which laboratory models it appears in. Verve supplies both strictly as in-vitro reference materials, and neither profile describes human or veterinary use.
BPC-157
Synthetic pentadecapeptide · tissue-repair research
BPC-157 is a synthetic pentadecapeptide, a chain of 15 amino acids, derived from a partial sequence of a protein identified in human gastric juice, sometimes referred to as Body Protection Compound. It is a stable, water-soluble peptide and one of the most frequently cited reference compounds in tissue-repair and cellular research.
full BPC-157 profile →IGF-1 LR3
Recombinant IGF-1 analog polypeptide
IGF-1 LR3 is Long R3 insulin-like growth factor 1, a recombinant analog of human IGF-1 carrying an arginine substitution at position 3 and a 13-residue N-terminal extension. Those two modifications are what define it: they substantially reduce its affinity for the insulin-like growth factor binding proteins (IGFBPs) that sequester native IGF-1 in culture systems.
full IGF-1 LR3 profile →Which research models is each compound studied in?
BPC-157 sits in recovery & gut research and IGF-1 LR3 in longevity & cellular research, so their listed models largely do not intersect. The table lists 5 reported research applications for BPC-157 and 5 for IGF-1 LR3. Rows are per compound, not equivalences.
| BPC-157 — reported research applications | IGF-1 LR3 — reported research applications |

What is BPC-157?
BPC-157 is a synthetic 15-amino-acid peptide (a pentadecapeptide) based on a sequence found in human gastric juice. Verve supplies it as a research compound for laboratory use only, not for human or veterinary use.
What is BPC-157 studied for in research?
In in-vitro and pre-clinical research it is used as a reference compound in models of tissue repair, angiogenesis, cell migration, and extracellular-matrix remodeling. Verve makes no claims about use in humans or animals.
What is IGF-1 LR3?
IGF-1 LR3 is Long R3 insulin-like growth factor 1, a recombinant analog of human IGF-1 with an arginine substitution at position 3 and an N-terminal extension. Verve supplies it as a research compound for laboratory use only, not for human or veterinary use.
How does IGF-1 LR3 differ from native IGF-1?
Its structural modifications reduce affinity for IGF binding proteins, so more of the ligand remains unbound in culture systems. Researchers use that property to control free-ligand availability in in-vitro models.
