Implicated or Admitted: Jose Canseco
Andriol (Testosterone Undecanoate, Mexican Beans)
Medical Use: Steroid used in treatment of testosterone deficiency, including hypogonadism, andropause and related conditions such as delayed puberty in boys.
Performance-Enhancing Use: It builds strength and muscle mass, aids workout recovery. A fast-acting steroids believed to clear the user’s system within a few days.

Implicated or Admitted: Barry Bonds, Jason Giambi, Bobby Estalella
The Clear (THG, Tetrahydrogestrinone, Norbolethone)
Medical use: None. An undectectable BALCO steroid. Related to gestrinone, a synthetic hormone used to treat the female gynecological condition endometriosis, and trenbolone, used to improve muscle quality in beef cattle.

Pecisely what is needed for swinging a bat or throwing a pitch. Shown in studies to increase the intensity of training workouts, enabling faster and more pronounced muscle growth.

Ephedra (Ephedrine)
Medical Use: Diet pill, Stimulant, Ancient Chinese: hay fever, asthma
Performance-Enhancing Use: stimulates the brain, increases heart rate, expands bronchial tubes (making breathing easier), good for working out. Amphetamine-like.
Side Effects: May include irritability, nervousness, dizziness, trembling, headache, vomiting and hyperthermia. Chemical dependence may also develop.
Implicated or Admitted: Steve Bechler
EPO (Erythropoietin, Epogen, Procrit)
Medical Use: Improves the ability of red blood cells to transport oxygen.
Performance-Enhancing Use: An artificial hormone that allows the blood to carry more oxygen, thus boosting endurance. It is favored by endurance athletes and has saturated such sports as professional cycling and cross-country skiing.
Side Effects: Circulatory strain as well as damming (clotting) in smaller blood vessels.
Implicated or Admitted: None in baseball.
Equipoise (Boldenone Undecylenate, Boldabol)
