Drugs in the Mitchell report ... and what they do

Some of the drugs listed in the Mitchell Commission report, and what each drug does:


Believed to be one of the strongest and, at the same time, most effective oral steroids. The compound has an extremely high androgenic effect which goes hand in hand with an extremely intense anabolic component. For this reason, dramatic gains in strength and muscle mass can be achieved in a very short time. An increase in body weight of 10-15 pounds or more in only 14 days is not unusual. Water retention is considerable, so the muscle diameter quickly increases and the user gets a massive appearance within record time.

Winstrol (or Stanozolol)

Technically classified as an anabolic steroid. The anabolic properties of this substance are mild in comparison to many other compounds, but it is still a good, reliable builder of muscle.


Sustanon 250 is an oil-based injectable containing four different testosterone compounds. The mixture of the testosterones is time-released to provide an immediate effect while still remaining active in the body for up to a month. As with other testosterones, Sustanon is an androgenic steroid with a pronounced anabolic effect. Therefore, athletes commonly use Sustanon to put on mass and size while increasing strength. However, unlike other testosterone compounds such as testosterone cypionate and testosterone enanthate, the use of Sustanon leads to less water retention and fewer estrogenic side effects.


Deca is one of the most popularly counterfeited steroids on the market. The drug itself is a moderate androgen and a highly anabolic preparation. It has proven to be an excellent product for promoting size and providing strength gains. It has minimal liver toxicity and aromatizes only in excessive dosages. Deca does have an effect on the body's natural hormone axis, yet it is not nearly as pronounced as it is with drugs like testosterone. This steroid has been used for cutting and for bulking. Athletes have stacked it with virtually every drug and reported positive results. It seems to be an excellent base drug on any cycle. Deca can be used by almost all athletes, with positive results and very few side effects. Deca-durabolin has gained a reputation as being somewhat of an alleviator of sore joints and tendons.


Dianabol is taken orally and has a great effect on protein metabolism. Dianabol effects protein synthesis and supports a buildup of protein. Dianabol is very powerful, in terms of both androgenic and anabolic effects on the user. The result of these effects will result in a great buildup of muscle mass and strength in a relatively quick period of time. That said, its main use is in mass building stacks. Dianabol is commonly combined with injectable testosterone products largely to kick-start the cycle to improve gains in muscle mass and strength before longer-acting testosterones go into full effect. There is an increase in weight, resulting from the hypertrophy (growth) of muscle fibers, as well as water retention. Since Dianabol is a 17-AA steroid, it should be noted that it is liver toxic if used in high doses or for extended periods of time (or both). Dianabol-only cycles are a poor idea for the novice, since Dianabol is a more powerful agent than most injectable steroids, and the athlete should work up to a level in which Dianabol can be used safely in a steroid stack. Dianabol is for the slightly more advanced athlete.

Veterinary Steroids

Often contain the same components as those prepared for humans but without the same quality control. Labels are always clearly marked as veterinary products. These may be water or oil based and injected in the same way as pharmaceutical steroids.
