Description
4-androstenedione is used to increase the production of hormone testosterone to enhance motor performance,increase energy,maintain erythrocyte health,enhance movement recovery and growth,and increase libido and performance.

Because of the ability of different parts of the body to convert it into hormones,testosterone and estrogen have a great impact on the body.

In females,the outer part of the adrenal(called the cortex)and the ovaries release 4-androstenedione into the blood,where they are converted to provide about half of the testosterone and almost all of the estrogen,an estrogen form.

Although testes produce large amounts of 4-androstenedione in males,they are hardly secreted into the blood,but are rapidly converted into testosterone in the testes.The adrenal gland also produces 4-androstenedione in males,but this contribution is exacerbated by testosterone testosterone testosterone that is repaired by the testes.

How is 4-androstenedione controlled?
Because of its secretion of a variety of different glands,and its often quickly converted to other hormones,so the body of 4-androstenedione control is very complex.However,it is important to know that two key parts of the brain(hypothalamus and pituitary)are important in controlling the secretion of 4-androstenedione in testes,ovaries and adrenal cortex.

Adrenal cortex release of 4-androstenedione is thought to be associated with pituitary gland secretion of specialized hormones,adrenocorticotropic hormone.However,it is true that corticotropin and other hormones control the production of 4-androstenedione in the adrenal gland is unclear.

Through the luteinizing hormone and follicle stimulating hormone to stimulate testicular and ovarian release of 4-androstenedione.These are released from the anterior pituitary to respond to the hypothalamic hormone signal.

What happens if I have too much 4-androstenedione?
The effect of excessive 4-androstenedione may be due to its conversion to estrogen or testosterone in vivo.

In men,too much 4-androstenedione can lead to estrogen and testosterone production imbalance,leading to breast development and other changes.Depending on the excess of 4-androstenedione,other changes,such as testicular changes may occur.

In women,excess body and facial hair growth(known as hirsutism),stagnation(amenorrhea),deterioration of genital changes may be due to excessive 4-androstenedione release.

Although 4-androstenedione is often abused by bodybuilders to build muscle mass,few studies have shown that long-term use may reduce muscle strength.Therefore,the exact consequences of having too much ambition are still unclear.
