1. IGF-1 is basically a polypeptide hormone that has the same some of the same molecular properties as insulin. IGF dose actually stand for insulin-like growth factor. IGF-1 is mainly responsible for long bone growth in children and it also affects muscle growth and repair of adults.

2. Long R3 IGF-1 is a more potent version of IGF-1. It's chemically altered i like to think "enhanced" to prevent deactivation by IGF-1 binding proteins in the bloodstream. This results in a longer half-life of 20-30 hours instead of 20 min... So that means a far more effective version than the short chain we we re perhaps more familiar with.

IGF1-LR3 What does it do

1. IGF-1 LR3 greatly boosts muscle mass by inducing a state of muscle hyperplasia (increase in number of new muscle cells) in the MUSCLE WHERE ITS INJECTED! So think of it as muscle cell proliferation, or even the splitting of the cell so 1 becomes 2... That's why its perfect on cycle when you get increased muscle cell growth too. But why is IGF better than HGH The reason being is HGH causes IGF levels to rise in the liver first, then then the muscle, Whereas IGF-LR3 causes localized IGF levels to rocket.

2. Igf1-lr3 As you all know is the long acting version of Igf-1, Taking its active potential up towards 20 hours, But along with its ability to stimulate the growth of satellite muscle cells and helping them to mature into new muscle fibers it holds the ability to increase the uptake of many supplements we currently use, And it can cause the enhanced recovery of testicle size, and prevent muscle loss even in PCT. Plus another reason its so potent is because of the decreased binding of Long R3 IGF-1 to all known IGF binding proteins. These binding proteins normally inhibit the biological actions of IGF.. not so with this long acting version.
