Counteracting the catabolic effect of long-term corticosteroid therapy. Although they have been indicated for this indication, AAS saw very little use for this purpose due to their virilizing side effects.

Last, but not least, steroids have disfiguring effects-severe acne, greasy hair, and baldness .
The measurement of the dissociation between anabolic and androgenic effects among AAS is based largely on a simple but outdated and unsophisticated model using rat tissue bioassays. In this model, myotrophic or anabolic activity is measured by change in the weight of the rat bulbocavernosus/levator ani muscle, and androgenic activity is measured by change in the weight of the rat ventral prostate , in response to exposure to the AAS. Development of breast tissue in males, a condition called gynecomastia , may arise because of increased conversion of testosterone to estradiol by the enzyme aromatase. Reduced sexual function and temporary infertility can also occur in males. Another male-specific side-effect that can occur is testicular atrophy, caused by the suppression of natural testosterone levels, which inhibits production of sperm .

New York State law bans the sale of dietary supplements containing the stimulent ephedra. Unfortunately, that creates some atheletes who are determined to win at any cost. And, they may use that determination to justify the use of anabolic steroids, despite evidence that these drugs can inflict irreversible physical harm and have significant side effects. Prevalence of anabolic steroid use is poorly researched, particularly in longevity. Individuals using AAS range from adolescent weight trainers to high level professional athletes and olympians.

Women treated with testosterone for breast cancer require monitoring for signs of virilization. Patients on testosterone should be monitored for their response to treatment and adverse effects three to six months after initiation of therapy and then every year, especially for cardiac adverse events. Changes in endogenous testosterone levels may also contribute to differences in myotrophic–androgenic ratio between testosterone and synthetic AAS. AR agonists are antigonadotropic – that is, they dose-dependently suppress gonadal testosterone production and hence reduce systemic testosterone concentrations.
In addition, because estered testosterone is dissolved in oil, intravenous injection has the potential to cause a dangerous embolism in the bloodstream. People who use anabolic steroids on a routine basis can have withdrawal symptoms when they stop taking them. Symptoms include having depression, being extremely tired, and having no desire to eat. Teens who misuse steroids are at a significant risk of suffering irreversible side effects, including stunted growth, accelerated puberty changes and abnormal sexual development.
Anabolic steroids are used illicitly to increase lean muscle mass and strength; resistance training and a certain diet can enhance these effects. There is pharmaqo labs that anabolic steroids increase endurance or speed, but substantial anecdotal evidence suggests that athletes taking them can perform more frequent high-intensity workouts. Endogenous androgen is responsible for the growth and development of the sex organs in men and maintaining secondary sex characteristics.
