IGF-1 LR3 (Long-R3 IGF-1) is a synthetic 83-amino-acid analogue of insulin-like growth factor 1 with 13 additional residues at the N-terminus and an arginine substitution at position 3. These modifications dramatically reduce binding to IGF-binding proteins, keeping the peptide in its active, unbound form.
The result is a longer-acting molecule (~20 h half-life) with stronger downstream IGF-1 receptor activation than native IGF-1.
