product description:

dianabol is a rapidly fast acting anabolic androgenic steroid that carries immense power and capabilities, and of all the anabolic steroids is one of the most important of all time. a favorite among competitive bodybuilders, strength athletes, gym rats and everything in-between, dianabol truly holds a special place in the hearts of many. milligram for milligram one of the most potent anabolic steroids on earth, while its value cannot be questioned what truly makes it special is its place in the history of anabolic androgenic steroids. dianabol was not the first anabolic steroid ever created, but its inception was early on, and in many ways is what birthed the anabolic race in the arena of performance. unlike many anabolic steroids, dianabol was created for the strict purpose of performance enhancement, and the desired purpose has been met with success, and that's we can assure you putting it quite mildly.

function & usage:

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 per day, but a dose of 100 mg had no significant effect on serum testosterone. however, 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.
because androstenedione can be converted to estrogenic steroids, people taking this supplement may have estrogenic side-effects.
in child development, higher levels of androstenedione in boys have been associated with higher levels of acting out behaviors.

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. thus, theca cells and granulosa cells work together to form estrogens.
used for simplified hormone drugs, from the testis or urine extracted with the role of a male hormone steroid, norethisterone, testosterone propionate in the middle body, is widely used in small rheumatoid arthritis, diuretic, and a variety of contraceptive to control infectious inflammation.
