IGF‑1 LR3 is a synthetic analogue of the natural hormone Insulin‑like Growth Factor‑1 (IGF‑1) — a protein involved in growth, muscle development, and cellular repair. In IGF‑1 LR3, one amino acid is substituted (arginine in position 3) and 13 extra amino acids are added on its end, which:

  • Makes it more potent than normal IGF‑1

  • Extends its activity in the body much longer (≈20–30 hours) than native IGF‑1’s ~12‑15 hour half‑life

This modification increases how long the peptide stays active and how effectively it binds to IGF‑1 receptors, enhancing its biological effects compared with regular IGF‑1.

IGF‑1 LR3 is typically supplied as a research peptide and is not approved for therapeutic use in humans — many sources emphasize that it’s intended for research or clinical investigation, not general consumption or sports performance enhancement.
