Research shows that older men and women with low testosterone have lower red blood cell counts and an increased risk of developing anemia. Anemia can produce symptoms like fatigue, weakness, loss ...
Administration of high-dose testosterone in men over a course of weeks can cause an increase in aggression and hypomanic symptoms, though these were seen in only a minority of subjects. [15] Acute high-dose anabolic-androgenic steroid administration in males attenuates endogenous sex hormone production and affects the thyroid hormone axis.
Anabolic steroids influence cellular differentiation while favoring the development of muscle cells over fat-storage cells. [138] Research in this field has shown that structural modifications in anabolic steroids are critical in determining their binding affinity to ARs and their resulting anabolic and androgenic activities.

It can manifest as precocious puberty, and is caused by abnormally high levels of testosterone or estrogen, crucial hormones for sexual development. In some cases, it may be caused by a tumor, which can be malignant, but is more commonly benign. [2] Anabolic steroids may also be a major cause of high androgen and estrogen functional activity.
The prevalence of gynecomastia in men may have increased in recent years, but the epidemiology of the disorder is not fully understood. [40] The use of anabolic steroids and exposure to chemicals that mimic estrogen in cosmetic products, organochlorine pesticides, and industrial chemicals have been suggested as possible factors driving this ...
Androgen deficiencies in women have also, as of 2001, been recognized as a medical disorder that can be treated with ART. [8] As with men, symptoms associated with androgen deficiency are most prevalent with age, and androgen replacement therapy has been shown to help with symptoms of menopause. [9]
A 2005 placebo-controlled study looked at men and women aged 45 to 65 with midlife-onset major or minor depression. Participants followed a six-week DHEA treatment plan that included 90 milligrams ...
Metandienone, also known as 17α-methyl-δ 1-testosterone or as 17α-methylandrost-1,4-dien-17β-ol-3-one, is a synthetic androstane steroid and a 17α-alkylated derivative of testosterone. [7] It is a modification of testosterone with a methyl group at the C17α position and an additional double bond between the C1 and C2 positions. [7]
