What It Is
IGF1-LR3 (Insulin-like Growth Factor 1 Long R3) is a modified version of IGF-1 with an extended half-life of 20 to 30 hours compared to native IGF-1’s half-life of minutes. The LR3 modification prevents binding to IGF binding proteins, keeping the compound active in circulation significantly longer.
What It Does
IGF1-LR3 promotes muscle growth, accelerates fat loss, improves recovery, supports nerve repair, and enhances cellular regeneration. It activates the same receptors as native IGF-1 but with much greater potency and duration. It is one of the most anabolic compounds available and is used extensively in performance and physique optimization.
How It Works
IGF1-LR3 binds to IGF-1 receptors throughout the body, activating the PI3K/Akt/mTOR pathway, which drives protein synthesis, cell growth, and muscle hypertrophy. It also activates satellite cells (muscle stem cells) and promotes hyperplasia (new muscle fiber formation) in addition to hypertrophy.
Who Benefits Most
Athletes and bodybuilders looking to maximize muscle growth and recovery. People with muscle wasting conditions. Anyone recovering from injury who needs accelerated tissue regeneration. People in longevity protocols looking to preserve muscle mass as they age.
Protocol and Dosing
Typical dose: 20 to 50 mcg injected subcutaneously or intramuscularly once daily. Often used post-workout. Cycle length: 4 to 6 weeks. Use with caution and under practitioner supervision due to potency.
| Vial Format | Total mcg | 20 mcg dose | 50 mcg dose |

Cautions
Potent anabolic compound. Use under practitioner supervision. May cause hypoglycemia at higher doses. Monitor blood glucose. Avoid if you have active cancer or a history of cancer. Not recommended during pregnancy. Do not use with insulin without medical supervision.
Pairs Well With
BPC-157 for injury recovery alongside muscle growth. Ipamorelin or CJC-1295 no DAC for comprehensive GH and IGF-1 optimization. TB-500 for systemic repair and recovery support.
