IG2 (IGF‑2) is a multi‑functional active growth‑factor peptide. It takes part in cell proliferation, tissue repair and metabolic regulation, while delivering powerful neuroprotection against oxidative‑induced nerve damage and central‑system inflammation.

This peptide improves memory performance, slows age‑related cognitive decline and safeguards dopaminergic neurons. It also regulates immune responses, accelerates soft‑tissue recovery and supports long‑term cellular health. Well‑tolerated with few adverse reactions, IG2 suits multi‑scene application for neural maintenance and tissue‑repair care.

ECHEMI Editorial Reference

Long arginine 3-IGF-1, abbreviated as IGF-1 LR3 or LR3-IGF-1, is a synthetic protein and lengthened analogue of human insulin-like growth factor 1 (IGF-1). It differs from native IGF-1 in that it possesses an arginine instead of a glutamic acid at the third position in its amino acid sequence ("arginine 3"), and also has an additional 13 amino acids at its N-terminus (MFPAMPLLSLFVN) ("long"), for a total of 83 amino acids (relative to the 70 of IGF-1).
