What is IGF-1 LR3 and what is MOTS-C?
IGF-1 LR3 is classified as Recombinant IGF-1 analog polypeptide; MOTS-C as Mitochondrial-derived 16-amino-acid peptide. 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.
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 →MOTS-C
Mitochondrial-derived 16-amino-acid peptide
MOTS-c is a 16-amino-acid peptide encoded not by nuclear DNA but by a short open reading frame within the mitochondrial 12S rRNA gene. It belongs to the mitochondrial-derived peptide family, a group of small peptides that are of interest in research precisely because their genetic origin sits inside the organelle rather than the nucleus.
full MOTS-C profile →Which research models is each compound studied in?
IGF-1 LR3 sits in longevity & cellular research and MOTS-C in weight & metabolic research, so their listed models largely do not intersect. The table lists 5 reported research applications for IGF-1 LR3 and 5 for MOTS-C. Rows are per compound, not equivalences.
| IGF-1 LR3 — reported research applications | MOTS-C — reported research applications |
|---|---|
| IGF-1 receptor binding and signal-transduction research | Mitochondrial-derived peptide and retrograde-signaling research |
| PI3K/Akt and MAPK pathway research in cellular models | AMPK pathway research models |
| Cell-culture media supplementation for proliferation research | One-carbon (folate–methionine) metabolism studies |
| IGFBP interaction and free-ligand availability studies | Cellular energy-metabolism and substrate-utilization research |
| Comparative analog research against native IGF-1 | Exercise-physiology and metabolic-stress research models |

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.
What is MOTS-C?
MOTS-c is a 16-amino-acid peptide encoded by a short open reading frame in the mitochondrial genome. Verve supplies it as a research compound for laboratory use only, not for human or veterinary use.
What is MOTS-C studied for in research?
It is used in mitochondrial-signaling research, including AMPK pathway activity, one-carbon metabolism, and retrograde signaling between mitochondria and the nucleus in in-vitro and pre-clinical models. Verve makes no health claims.
