Introducing a derivative of testosterone into the body has the strong potential to cause a number of hormonal disturbances, notably long term suppression of the body’s ability to produce normal levels of androgen hormones, which can cause infertility, testicular atrophy, gynaecomastia (man boobs) and increase the risk of testicular cancer in men (5,6). Women run the risk of developing masculine features – often times these changes are irreversible. Severe acne and hair loss are also very common side effects of Oxandrolone abuse (7). Mental disturbances are common, and a large number of steroid users experience psychological dependence and develop mental and physical withdrawal symptoms when they try to quit (8). Aggression (roid rage), mood swings, mania and depresssion are potentially devastating side effects that can arise from Oxandrolone abuse (7).
Side effects of testosterone enanthate include symptoms of masculinization like acne , increased hair growth , voice changes , and increased sexual desire .  The drug is a synthetic androgen and anabolic steroid and hence is an agonist of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT).   It has strong androgenic effects and moderate anabolic effects, which make it useful for producing masculinization and suitable for androgen replacement therapy .  Testosterone enanthate is a testosterone ester and a long-lasting prodrug of testosterone in the body.    Because of this, it is considered to be a natural and bioidentical form of testosterone.
