IGF-1 is naturally produced from both Insulin and growth hormone in the liver and other tissues. IGF-1 is made up of 70 amino acids in a chain. When IGF-1 is altered by removing the last 3 amino acids in the IGF-1 chain (the N-terminal tri-peptide), it becomes Des (1-3) IGF-1 which is way more anabolic.
