IGF stands for . Insulin-like growth factor 1 () is a similar in molecular structure to insulin . It plays an important role in childhood growth and continues to have anabolic effects in adults. It is a natural substance that is produced in the human body and is at its highest natural levels during puberty. During puberty is the most responsible for the natural muscle growth that occurs during these few years. There are many different things that IGF does in the human body. Among the effects the most positive are increased amino acid transport to cells, increased glucose transport, increased protein synthesis, decreased protein degradation, and increased RNA synthesis. Cycles The most effective length for a cycle of IGF is 50 days on and 20-40 days off. The most controversy surrounding Long R3 IGF-1 is the effective dosage. IGF Dosage The most used dosages range between 20mcg/day to 120+mcg/day. IGF is only available by the milligram, one mg will give you a 50 day cycle at 20mcg/day, 2mg will give you a 50 day cycle at 40mcg/day, 3mg will give you a 50 day cycle at 60mcg/day, 4mg will give you a 50 day cycle at 80mcg/day and so on. The dosage issue mainly revolves around how much money you have to spend, plenty of people use the minimum dosage of 20mcg/day and are happy with the results. IGF is most effective when administered subcutaneous and injected once or twice daily at your current dosage. The best time for injections is either in the morning and/or immediately after weight training (if used for body building).
