I got a steroid shot yesterday for my allergy reaction. why is it a steroid, will this need get me buff?

3 types of steroids: Dexamethasone and similar drugs are of the glucocorticoid type of steroid drugs, and has uses in a variety of disorders. It has anti-inflammatory effects and suppresses the immune system's activity (thus treats allergic reactions). Anabolic steroids (type of sex steroids) are abused by some people to increase muscle mass. The third type of steroid are the mineralcorticoids (affects salt balance).
