1) exuberant secretion period (youth before 25 years old)
During this period, the function of endocrine system is strong, the secretion of various bioactive peptides is balanced, and the human immune function is strong, so the human body is generally not prone to diseases. After the age of 25, the secretion will decrease by 15% every 10 year.
2) Low secretion period (30-50 years old, prime and middle age)
Around the age of 30, various organs and tissues of the human body began to age and shrink, and their functions declined. The secretion of various bioactive peptides is only 85% of the peak period. At the age of 45, both men and women will experience a sharp decline from appearance (such as rapid skin relaxation and aging) to physical 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) hyposecretion period (middle-aged and elderly people over 50 years old)
At the age of 60, the secretion of active peptides is only about 1/5 of the peak, and at the age of 80, only110 is left. During this period, if the active peptides are seriously lacking and unbalanced, 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, leading 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, emotional stress, environmental pollution, unhealthy diet and other factors lead to the "sub-health" state of the human body, the overload operation 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, supplementing exogenous small molecular peptides is very beneficial to any population.
