Steroids
The structure of steroids have multiple rings. Some expamples of steroids are "cholesterol" and "testosterone". Cholesterol can be found in many different cell membranes. Testosterone is a male steroid hormone [1].
In Sports Med. 2004;34(8):513-54. Hartgens et. al (2004) said that "Androgenic-anabolic steroids (AAS) are synthetic derivatives of the male hormone testosterone. They can exert strong effects on the human body that may be beneficial for athletic performance".
