IGF-1 LR3 or also knowns as LR3-IGF-1, is a synthetic protein and lengthened analog of human insulin-like growth factor 1 (IGF-1). IGF-1, has a number of structural similarities with insulin, which is how it got its name.
The Long R3 IGF-1 version is significantly more potent than regular IGF-1 due to the decreased binding of IGF1 LR3 to all known IGF binding proteins. The IGF-1 LR3 analog of IGF-1 was created to increase the bioactivity of the IGF peptide and give it a longer half life; between 20 to 30 hours.
IGF-1 LR3 frequently gets applied in medical practice, as well as power sports to increase the power indicators of bodybuilders, boost endurance and more.

Research has shown an effective dose to be between 50 mcg to 150 mcg per day.
It is suggested to administer the subjects dose on a day during physical training is either before or after exercise.
It is suggested that this compound not be used more than a maximum of 30 days consecutively.
