What is Testosterone?

Testosterone is the principal male sex hormone and an anabolic androgenic steroid. Testosterone is a naturally occurring hormone in humans that plays a key role in normal growth and development of male secondary sex characteristics. To be used legally, this substance requires a legitimate prescription from a physician.

What are the common names or slang terms for Testosterone?

Testosterone is commonly referred to as Test. Injectable forms of the steroid Testosterone include Testosterone Propionate (“Test Prop” or “Prop”), Testosterone Cypionate, and Testosterone Enanthate (“Test E” or “Enan”). An injectable steroid called Sustanon (“Sus” or “Sust”) contains four different Testosterone compounds and is also illegally sold under the commercial name Testonon.

What are its short and long-term effects on the body?

Although anabolic androgenic steroids like Testosterone may increase lean muscle mass, strength, and the ability to train longer and harder, the serious side effects of steroids are many and may not be reversible. The minor side effects of steroid use include acne, oily skin, excess hair growth, and deepening of the voice. The major side effects of steroid use include an increased risk of cancer, increased risk of heart and liver disease, jaundice, fluid retention, reduction in HDL-C (“good cholesterol”), high blood pressure, changes in blood coagulation, increased risk of atherosclerosis, swelling of the soft tissues of the extremities (edema), and obstructive sleep apnea.

Side effects specific to men can include testicular atrophy or the shrinking of the testicles, reduced sperm count, infertility, baldness, and the development of breasts. For women, side effects can include enlargement of the clitoris, changes in the body contour growth of facial hair, disruption of the menstrual cycle, deepened voice and infertility.

An increase in androgenic (male) hormones from steroid use may also lead to aggressive behavior. Research also indicates that steroid users often suffer from paranoid jealousy, extreme irritability, delusions, and impaired judgment stemming from feelings of invincibility.

Adolescents who abuse steroids like Testosterone are at a significant risk of suffering irreversible side effects, including stunted growth, accelerated puberty changes and abnormal sexual development. Adolescent girls in particular may suffer from severe acne, excessive body and facial hair, deepened voice, permanent enlargement of the clitoris, disruption of the menstrual cycle, and permanent infertility.

Testosterone users also are very likely to experience flu-like symptoms upon commencing a cycle of Testosterone. This common occurrence is often referred to as “Test Flu” or “Sustanon Flu” (“Sus Flu”).

What is its federal classification?

Testosterone is included in Schedule III of the Code of Federal Regulations' Schedule of Controlled Substances.
