Injectable steroids are synthetic chemicals that mimic the hormones naturally produced by the body. They are most commonly used in bodybuilding to increase muscle mass, strength, and performance. The popularity of steroids has grown significantly over the past decade or so as they become more accessible and affordable.

steroids work by increasing protein synthesis in the muscles, which leads to an increase in muscle size and strength. They also reduce the amount of time it takes for the muscles to recover after a workout, allowing athletes to train more often and at higher intensities. Additionally, steroids can improve endurance levels, enabling athletes to perform better during competition.
