Growing old is a fact of life and its inevitable. Our metabolism slows, skin starts to wrinkle, muscles get weaker and energy plummets. But why do we age?

Human Growth Hormone (HGH) is a single-chain peptide hormone produced from the pituitary gland, the master gland in the body. This is the hormone that helps you grow throughout childhood, hence the word “growth”. HGH is at its highest level around the age of 20, and then plummets at 25 and slowly declines from there. This is when the aging process begins for the rest of your life.
