It's not really a stupid question. All steroids are testosterone analogs. That means they are similar in function, but not in origin or structure. I can see you have been studying. You just misinterpeted this particular fact. Being a testosterone analog is not the same as being a synthetic version. Some of the differences are very subtle. Such as a hydrogen molecule added to the molecule chain at a certain position. As a matter of fact, Dianabol and Equipoise are very similar structerally, but the difference in how they affect your body are enormous. Nandrolone or Deca is actually derived from DHT not testosterone. So, since their structure is different they affect the body through different pathways or the androgen receptors recognize them in different ways. Since I'm not a scientist, this is my a,b,c explaination. I hope it helps make sense of it all.
