IGF-1 LR3
Long-acting IGF-1 analog — promotes muscle hypertrophy, fat loss, and cellular repair.
What Is IGF-1 LR3?
IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a modified analog of IGF-1 with significantly extended half-life due to its reduced binding to IGF-binding proteins. It promotes cellular growth, differentiation, and protein synthesis through IGF-1 receptors throughout the body. Studies show potent anabolic effects including lean muscle hypertrophy, accelerated injury recovery, fat loss via lipolysis, and bone mineral density improvements. Its extended activity window makes it more practical than native IGF-1.

Applications & Benefits
Effect Timeline
Expected milestones based on published preclinical data.
First amplified GH pulses detected. Slight IGF-1 elevation begins; anabolic signaling pathways activate.
IGF-1 levels plateau at elevated baseline. Protein synthesis increases; recovery from training improves noticeably.
Lean mass accumulation measurable. Fat oxidation increases; sleep quality improvements typically reported.
Maximum body composition improvements at sustained elevated GH/IGF-1 levels. Anti-aging mechanisms fully engaged.
