IGF-1's anabolic effects are limited only by amino acid supply within muscle cells (6,7) . muscle pictures Lumbar-steroid-epidural-injections. In essence, the more you eat, the more you grow with IGF-1. Unfortunately, simply elevating serum IGF-1 has not proven to be anabolic in healthy individuals (1,2,3). In addition, the side effects of using significant dosages make using pure IGF-1 prohibitive. muscle pictures Steroid-pictures. IGF-I does not naturally exist in quantity free of its binding proteins, and limitations associated with administering free IGF-I (i. e. Long R3IGF-1) therapeutically have proven significant: acute insulin effects (e. muscle pictures Steroid-comparison-chart. g. hypoglycemia), suppression of growth hormone secretion, edema, hypotension, tachycardia, very short circulating half life, and limited and transient efficacy at safe dosage levels (8,9,10). LR3IGF-I has very low affinity for the IGF-binding proteins in the rat and hence is cleared from the circulation more quickly than is IGF-I. Yet because it stays free from binding proteins it is generally more potent unit per unit. However, the extremely short half life has made it impractical for muscle growth. Somatokine?When IGF-I is bound to binding protein-3 (BP3), as it is in nature, it does not display these acute limitations. Furthermore, BP3 appears to be critical in the regulation of the release of IGF-I to target tissue sites, where the hormone is active only when needed. There is some confusion among athletes that IGF-1 binding proteins actually limit the effectiveness of IGF-1. In reality, IGFBP3 is necessary to prevent IGF-1 from being cleared from the system. IGFBP3 extends IGF-1's half-life from minutes to hours. BP3 is also a necessary part of the existing system which uses the binding protein and an acid labile subunit (ALS) which is broken down at target tissue, releasing the IGF-1 when and where it is needed. So what is Somatokine? A company called Celtrix pharmeceuticals produces only one product, namely Somatokine. In fact, the company hasn't even received FDA approval yet, though late phase testing is proving to be very promising (Data privately held by Celtrix).
