The anabolic steroid family tree is a framework that simplifies how different steroids impact muscle building and performance.

In general, the most commonly used anabolic steroids fall into one of three different families/categories.

Testosterone and its derivatives, Dihydrotestosterone (DHT) and its derivatives, and Nandrolone (19-Nortestosterone) and its derivatives.

Expectedly, many of the anabolic steroids in each family have similar attributes to one another.

There are exceptions to this in each family, but in general breaking down anabolic steroids into the three families provides a simplified framework to identify the targeted action of each compound, as well as how they impact muscle building and overall performance.
