Description IGF-1 LR3 (Long Arg3 Insulin-Like Growth Factor-1) is a recombinant peptide analog of human IGF-1, engineered with a substitution of arginine at position 3 and a 13-amino-acid N-terminal extension. These modifications significantly increase its biological half-life (up to ~20–30 hours) and reduce its binding to insulin-like growth factor-binding proteins (IGFBPs), resulting in enhanced bioavailability and potency. IGF-1 LR3…
Description Ipamorelin is a synthetic pentapeptide that functions as a ghrelin receptor (GHSR-1a) agonist, stimulating the release of growth hormone (GH) from the anterior pituitary. It is part of the GHRP (growth hormone-releasing peptide) family but is distinguished by its high selectivity and minimal impact on other pituitary hormones such as cortisol and prolactin. Research has focused on Ipamorelin’s…
