1) The period of exuberant secretion (youth before the age of 25)
During this period, the endocrine system is full of functions, the secretion amount of various bioactive peptides is balanced, the human body has strong immune function, and the human body is generally not prone to diseases. After the age of 25, the secretion will decrease by 15% every 1 years.
2) Under-secretion period (3-5 years old, prime and middle age)
Around 3 years old, various organs and tissues of human body began to age and shrink, and their functions declined, and the secretion of various bioactive peptides was only 85% of the peak period. When people reach the age of 45, both men and women will experience a sharp decline from appearance (such as rapid skin relaxation and aging) to body physiology (hypogonadism), and the functions of human nervous system and immune system will undergo a series of changes, resulting in various related sub-health states and mild disease symptoms.
3) Secretion deficiency period (middle age and old age over 5 years old)
At the age of 6, the secretion of active peptides is only about 1/5 of the peak period, and at the age of 8, it is only less than 1/1. During this period, if there is a serious shortage and imbalance of active peptides, there may be very prominent aging symptoms or various related diseases.
4) Secretion termination period
During this period, due to the decline of cell function, organ failure and loss, active peptides are no longer secreted, which leads to the end of life. With the natural aging of the human body, the number of active peptides secreted by the human body will gradually decrease. However, the fast pace of modern life, fierce competition for survival, great emotional pressure, environmental pollution, unhealthy diet structure and other factors have caused the human body to be in a "sub-health" state, with the overload of various functional organs and the decline of physiological functions. Exogenous small molecular peptides not only have strong nutritional value, but also have the function of regulating human metabolism and physiology, which is very important for maintaining normal life activities. Therefore, it is very beneficial for any population to supplement exogenous small molecular peptides.
