Primobolan is a Dihydrostestosterone (DHT) derivative (a modified form of DHT), where it contains a double-bond between carbon atoms 1 and 2 in the DHT structure. This allows stabilization of the 3-keto group which increases the anabolic effect. A 1-methyl group is also added to the structure, which allows it to resist hepatic (liver) metabolism and breakdown.
