Anadrol steroid is used for both strength and weight gains but it does not come without a price. Most users of Anadrol steroid report getting gyno about 50% of the time. Anadrol steroid gains a major water weight gain.  The gains that you will get on Anadrol will go away after you get off of it. This is pretty hard to take when you take into account how much it costs and the long-term side effects. 

Anadrol has been associated with liver toxicity. Peliosis hepatis, a condition in which liver and sometimes splenic tissue is replaced with blood-filled cysts, has been reported in patients receiving androgenic anabolic steroid therapy. These cysts are sometimes present with minimal hepatic dysfunction, but at other times they have been associated with liver failure. They are often not recognized until life-threatening liver failure or intra-abdominal hemorrhage develops.  

Withdrawal of drug usually results in complete disappearance of lesions. Liver cell tumors are also reported. Most often these tumors are benign and androgen-dependent, but fatal malignant tumors have been reported. Withdrawal of drug often results in regression or cessation of progression of the tumor. However, hepatic tumors associated with androgens or anabolic steroids are much more vascular than other hepatic tumors and may be silent until life-threatening intra-abdominal hemorrhage develops.  

May affect the levels of certain substances, called lipids, which have been associated with an increased risk of heart and artery disease. Blood lipid changes that are known to be associated with increased risk of atherosclerosis are seen in patients treated with androgens and anabolic steroids. These changes include decreased high-density lipoprotein and sometimes-increased low-density lipoprotein. The changes may be very marked and could have a serious impact on the risk of atherosclerosis and coronary artery disease.   

Anadrol is chemically similar to the main male hormone (testosterone) and women taking Anadrol are at risk for developing such masculine characteristics as facial hair, hair loss, or a deeper voice.      

Oxymetholone (Anadrol), is a synthetic anabolic steroid developed by Syntex in 1960. Its primary clinical applications include treatment of osteoporosis and anaemia, as well as stimulating muscle growth in undernourished or underdeveloped patients. The drug was approved for human use by the FDA. However, later non-steroidal drugs such as Epogen were developed and proven to be more effective as a treatment for anaemia and osteoporosis without the side-effects of oxymetholone. The drug remained available despite this, and eventually found a new use in treating HIV wasting syndrome. While classified as a Schedule III drug under the Controlled Substances Act, it remains available via prescription as Anadrol (registered as a trademark of Unimed Pharmaceuticals.)

Presented most commonly as a 50 mg tablet, Oxymetholone is the strongest androgenic steroid available. Similarly, it also poses the greatest risk of side effects of any steroid. Despite very low binding affinity with the androgen receptor, oxymetholone is highly effective in promoting extensive gains in body mass, mostly by greatly improving protein synthesis. For this reason, it is often used illegally by bodybuilders and athletes. Many athletes also use Oxymetholone as a method of protection for the joints under heavy loads. Due to the high water retention users experience from this drug, it similarly lubricates the joints and helps protect them from injury. Oxymetholone is widely considered by bodybuilders to have the strongest anabolic effect out of any oral steroid available; weight increases of 20 pounds in 2 weeks are not unusual of with this drug.
Side effects:
The side-effects of short-term use of the drug itself include nausea, bloating, acne, and masculinising effects such as deepening of the voice, growth of facial hair and clitoral hypertrophy . In addition, oxymetholone is readily aromatized by aromatase to form a progestagen, and unless selective estrogen receptor modulators such as tamoxifen or clomifene are taken in conjunction with the drug, there is a significant risk of the appearance of estrogenic effects such as gynaecomastia over time. Because of its 17α-alkylated structure, oxymetholone is highly hepatotoxic. Long term use of the drug can cause a variety of serious ailments, including hepatitis, liver cancer, and cirrhosis. It is very dangerous to take oxymetholone in high dosages for periods of time exceeding six weeks, and is commonly used by bodybuilders during the start of a steroid cycle to help gain mass and increase serum levels of androgens quickly.
Use with other steroids:
To further increase its effectiveness as an anabolic agent, bodybuilders typically stack (see steroid stack) oxymetholone with other anabolic steroids. Since it is already a very potent androgen, many users will combine it with drugs such as nandrolone, boldenone and testosterone to further their gains.
