Androstènedione

Safe Testosterone Level Increasing Prohormone Androstenedione Powder

La description:
Androstenedione is also called 4-Androstenedione.
It is used to increase the production of the hormone testosterone to enhance athletic performance

, increase energy . keep red blood cells healthy , enhance recovery and growth from exercise,

and increase sexual desire and performance.

Application:
4-Androstenedione is the common precursor of male and female sex hormones. Some

4-Androstenedione is also secreted into the plasma, and may be converted in peripheral tissues

to testosterone and estrogens.

4-Androstenedione can be synthesized in one of two ways. The primary pathway involves

conversion of 17-hydroxypregnenolone to dehydroepiandrosterone by way of 17,20-lyase, avec

subsequent conversion of dehydroepiandrosterone to 4-Androstenedione via the enzyme 3-β-

hydroxysteroid dehydrogenase. The secondary pathway involves conversion of 17-

hydroxyprogesterone, most often a precursor to cortisol, to 4-androstenedione directly by way of

17,20-lyase. Ainsi, 17,20-lyase is required for the synthesis of 4-androstenedione, whether

immediately or one step removed.
The production of adrenal 4-Androstenedione is governed by ACTH, whereas production of

gonadal 4-Androstenedione is under control by gonadotropins. In premenopausal women, le

adrenal glands and ovaries each produce about half of the total 4-androstenedione(about 3

mg/jour). After menopause, 4-androstenedione production is about halved, due primarily to the

reduction of the steroid secreted by the ovary. Nevertheless, 4-androstenedione is the principal

steroid produced by the postmenopausal ovary.
 

Usage:
Simplified hormone drugs, from the testis or urine extracted with the role of a male hormone

steroids, norethisterone, testosterone propionate in the middle Body, is widely used in small

rheumatoid arthritis, diuretic, and a variety of contraceptive to control infectious

inflammation.

4-Androstenedione is further converted to either testosterone or estrogen.
In males, conversion of androstenedione to testosterone requires the enzyme 17β-

hydroxysteroid dehydrogenase.

In females, androstenedione is released into the blood by theca cells. Conversion of

androstenedione to estrogen (e.g., estrone and estradiol) requires the enzyme aromatase.

Androstenedione is a substrate for estrogen production in granulosa cells which produce

aromatase. Ainsi, theca cells and granulosa cells work together to form estrogens.

inflammation.

Effect:
Because androstenedione can be converted to estrogenic steroids, people taking this

supplement may have estrogenic side-effects.

4-Androstenedione has been shown to increase serum testosterone levels over an eight-hour

period in men when taken as a single oral dose of 300 mg par jour, but a dose of 100 mg had no

significant effect on serum testosterone. Cependant, serum levels of estradiol increased

following both the 100 mg and 300 mg doses. The study also reported that the serum level of

estrogens and testosterone produced varied widely between individuals.

In child development, higher levels of androstenedione in boys have been associated with

higher levels of acting out behaviors.

Dosage:
Dietary supplement dosages of androstenedione range from 5 to over 50mg per day in the

morning or 60 minutes before working out. Experts suggest the best way to take andro is by

cycling it. The proper cycle is six weeks of taking it followed by two weeks off.
