About IGF-1 LR3.
IGF-1 LR3 is a synthetic 83-amino-acid analogue of insulin-like growth factor 1, with a 13-amino-acid extension at the N-terminus and an arginine-3 substitution that prevents binding by IGFBPs. The result: a half-life of ~20–30 hours vs. ~10 minutes for native IGF-1.
The molecule is potent. It must be prescribed carefully — IGF-1 drives both desired and undesired anabolic effects.
IGF-1 LR3 binds the IGF-1 receptor on most cell types and triggers PI3K-Akt-mTOR signalling, driving protein synthesis, cell proliferation and tissue repair. Its escape from IGFBP binding gives it free access to receptors throughout the body.
Subcutaneous injection, typically 20–40 mcg daily, cycles of 4 weeks with re-evaluation. Local injection close to an injury site is preferred when appropriate.
