IGF-1 LR is a major hormonal mediator of statural growth. IGF stands for (Insulin-like Growth Factor) which typically comes in a 1 mg vial. LR3 Is a synthetic protein and lengthened analogue of human insulin-like growth factor 1. It will affect bone and muscle growth and repair of the muscles just as how other peptide does its work. It works together effectively with growth hormone.
Under regular circumstances, GH (growth hormone) binds to its receptor in the liver, and other tissues, and stimulates the synthesis/secretion of IGF-1. Both works and produce similar results, however, IGF-1 does it faster for those who respond to it. GH has some additional benefits like overall body rejuvenation, smoother skin, hair growth and others, which makes it among the preferred peptide by anti-aging users.
