estosterone is greatly reduced. Steroids also affect the functioning of neurons and the limbic system. The limbic system is in charge of many things such as learning, memory, and regulation of moods. So when steroids are taken it can cause learning disabilities, loss of memory, and dramatic mood swings (The Steroid Facts).There are three types of steroids: hydrocortisone, female sex hormones, and male sex hormones. Hydrocortisone steroids are a medical form of steroids found in creams and oils and are used to control rashes, itching, and inflamation. They are not thought to be addictive. Female sex hormones, also known as estrogen and progestogens, cause the development of secondary sexual characteristics in women and maintain the female reproduction system. These are also not thought to be addictive. Male sex hormones, or testosterone, lead to the development of male secondary sexual characteristics and maintain the male reproductive system. Testosterone drugs have just recently been thought to be addictive (Anabolic Steroids).As I mentioned before there are two ways to take steroids. Orally in pill form or by injections in to the muscle. Oral steroids are becoming increasingly popular because they stay in the body for only a couple weeks after their use is stopped. The down side of oral steroids is that they cause more damage to the liver and kidneys than injectable steroids do. Injectable steroids also stay in the body for up to several months after use making the person at risk of failing a drug test. Injectable steroids are used by injecting the steroid into the muscles (butt, thigh, or shoulder). It is also quite popular by users to "stack," or take a couple different types of steroids at once to maximize gains. Steroids are usually taken in cycles which are periods of time that a steroid is taken. There is no evidence that shows just how long a cycle should be so it is all a guess and passed by word of mouth. So...
