IGF-1 LR3
Why it is for you
LR3 suits a trained person who wants more muscle and faster repair than growth hormone peptides alone give, or someone holding muscle through a hard diet or illness. It fits the root-cause picture of low IGF-1 action at the tissue, where the signal reaches the liver but not enough reaches the muscle. It pairs with a growth hormone peptide such as CJC-1295 and ipamorelin, which raise the body's own IGF-1 and release fat. It is not for anyone with a cancer history, because IGF-1 drives cell growth.
