Description
Product Comparison
IGF-1 is a key factor in mediating the growth-promoting effects of growth hormone (GH) 5. This particular IGF-1 species was developed in order to avoid interaction with IGFBPs (Insulin Like Growth Factor Binding Proteins), which are known to hinder the activity of native IGF-1 over time6. By avoiding this interplay, IGF-1 LR3 is capable of achieving a very long half-life, which leads to its utility as a long-acting, extremely active facilitator of GH-stimulated anabolic activity.
Compared to IGF-1 DES, IGF-1 LR3 is considered to be less active as a stimulant of acute hyperplasia. This said, IGF-1 LR3 with its sustained in vivo activity is able to induce hypertrophic activity over long periods of time, whereas native IGF-1 and IGF-1 DES lack this functionality7.
IGF-1 LR3 and IGF-1 DES have both been demonstrated as more active biological agents relative to native IGF-1 when it comes to stimulating new cell growth in animal trials.
Studies investigating the effects of concurrent IGF-1 species and GH (or GH secretagogue) administration have identified their synergy5 in promoting the development of lean body mass and reduction of fat stores in test subjects.
