For those interested in how effective steroids are in promoting mustle growth the following study is informative:
Testosterone dose-response relationships in healthy young men, Am J Physiol Endocrinol Metab. 2001 Dec;281(6):E1172-81.
http://ajpendo.physiology.org/cgi/co...ll/281/6/E1172
61 men from the ages of 18-35 were given weekly testosterone injections for 20 weeks. The top two groups recieved 300 mg and 600 mgs weekly (injections). The men had previous weighlifting experience but did zero strength training during the trial. Here is the average gain in lean muscle mass for the top two groups:
Fat Free Mass by underwater weighing
300 mg group-5.2kg (11.4lbs) increase
600 mg group-7.9kg (17.38lbs) increase
Fat Mass by underwater weighing
300 mg group-.5kg (1.1lbs) decrease
600 mg group-1.1kg (2.42lbs) decrease
that's right over 17 pounds of muscle gain when they did no strength training. They also lost some fat.
Side Effects:

Side Effects:
Adverse experiences and safety measures. Hemoglobin levels decreased significantly in men receiving the 50-mg dose but increased at the 600-mg dose; the changes in hemoglobin were positively correlated with testosterone concentrations (r = 0.66, P = 0.0001) (Table 7). Changes in plasma HDL cholesterol, in contrast, were negatively dependent on testosterone dose (P = 0.0049) and correlated with testosterone concentrations (r = -0.40, P = 0.0054). Total cholesterol, plasma low-density lipoprotein cholesterol, and triglyceride levels did not change significantly at any dose. Serum PSA, creatinine, bilirubin, alanine aminotransferase, and alkaline phosphatase did not change significantly in any group, but aspartate aminotransferase decreased significantly in the 25-mg group. Two men in the 25-mg group, five in the 50-mg group, three in the 125-mg group, seven in the 300-mg group, and two in the 600-mg group developed acne. One man receiving the 50-mg dose reported decreased ability to achieve erections.
