IGF-1 LR3

Long-acting IGF-1 analog with reduced binding-protein affinity — direct anabolic signaling, much stronger than native IGF-1.

IGF-1 is the hormone that does most of growth hormone's actual muscle-building work — GH largely just tells the liver to make IGF-1. This version (Long R3) is engineered to dodge the binding proteins that normally switch native IGF-1 off within minutes, so it stays active for a day or more and signals far more powerfully. The payoff is strong, direct muscle growth — bigger fibres and more of them — plus fast recovery. The catch is that you've bypassed the body's own safety dial: it pushes growth in everything it reaches, which is why it carries the real risks below.
