Product Name:Igf-1 lr3 Alias:Long R3-IGF-1,IGF-1 Long R3 Molecular formula: C400H625N111O115S9 Molecular Weight : 9117.5 CAS number: 946870-92-4 Appearance : Fine White Lyophilized Powder Purity : 95% Specification:0.1mg/vial Grade : Pharmaceutical Grade Long arginine 3-IGF-1, abbreviated as IGF-1 LR3 or LR3-IGF-1, is a synthetic protein and lengthened analogue of human insulin-like growth factor 1 (IGF-1).IGF-1 (Insulin-like growth factor) is an endocrine hormone that is produced in the liver. The production of IGF-1 is increased in the presence of growth hormone. There are many different types of cells in the body that are equipped with a receptor to accept IGF-1. This makes IGF-1 a good protagonist at targeting tissues to spur cell to cell communication (growth) or in a more autocrine cell signaling process that facilitates cell division. IGF-1 LR3 has a half-life of about 20-30 hours and is much more potent than base IGF-1. Since its half-life is about a day, the IGF-1 LR3 will circulate the body, for around 24 hours, binding to receptors and activating cell communication that improves muscle growth and fat loss. LR3 prevents glucose from entering into cells, which, in turn, forces the body to burn fat and not sucrose. In addition, its long half-life is desirable for another reason; site injections aren't necessary, as IGF-1 LR3 will cycle the body binding to all muscle cells for about a day. IGF-1 Benefits Why is this IGF-1 important for a bodybuilder or athlete? Let’s take a look at the list: Helps regulate fat for use as energy, resulting in fat loss. Contributes to anti aging. As we get older, IGF-1 production slows down and this results in cell reduction. Low levels of IGF-1 are linked to heart failure, lower brain cell regulation and neuron function. Not to mention muscle tissue breakdown. Helps to increase nutrient shuttling (protein synthesis). Increases regenerative functions of nerve tissues. Boosts the ability to cause hyperplasia in muscle cells resulting in fuller muscle tissue. Recommended dosage cycles IGF-1 LR3 can be taken 7 days a week at a dose of 50-150mcg a day. Desensitization was shown to occur at around 40 days or roughly 4 weeks. Injection sites can be at any muscle group on the body, as it's not very good at site specific growth.
