Robert Tan, ., founder and director of the Houston-based OPAL Medical Clinic, which focuses on men’s health, has one explanation: “Public policy and public opinion have been based on people who use steroids in larger amounts,” he says. Tan, whose practice has been incorporating hormone replacement therapy for 15 years, says that in Texas, “every prescription is tracked by the DEA, so a lot of physicians are not comfortable. If I write a lot of steroids prescriptions, very soon they’ll be knocking down my door and looking at my records.”
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.
