Dr. Formulated Natural Factor for Growth Now the #1 selling formula of its kind in the United States*, Secretagogue-One was originally formulated by Dr. Vincent C. Giampapa, a world renowned leader in hormonal replacement therapy, for use by the patients of his anti-aging clinic. Now, after many success stories later, and after the benefits of this groundbreaking formula have been discovered by bodybuilders and fitness enthusiasts alike, Secretagogue-One is available to you through a collaborative effort between MHP and Dr. Giampapa. What is HGH? Human Growth Hormone or HGH (also known as somatropin) is produced by the pituitary gland and is essential for growth and regeneration of cells and tissues. Your body’s production of HGH is very high during childhood and adolescence. Unfortunately, after age 20 the release of HGH by the pituitary gland falls at a rate of approximately 14% every 10 years. By age 60, a loss of 75% or more of HGH is not uncommon. Physical symptoms of decreased HGH production include wrinkles, increased body fat, loss of muscle mass, loss of energy, among others. Secretagogue-One is a rejuvenation support formula comprised of secretagogues and other precursors that have been shown to support your body so that it may naturally release more of its own Human Growth Hormone (HGH). Coupled with an effervescent delivery system to improve absorption, these secretagogues are delivered in a proprietary "Glucose Polymer Matrix", providing nearly 100% assimilation as opposed to only 10-15% absorption with competing secretagogue products
