Anabolic steroids are used to quicken muscle tissue to grow. They can remain in the body anywhere from a couple of days to about a year. Steroid addicts who inject the drugs with a needle are at risk for infection with HIV, that causes AIDS, if they share needles with other users.
I definitely agree with molly. It's very unwise to take steroids and it’s not worth all the health problems you will have later on in life.
