How could

ras have taken steroids or other PED’s and still be that tiny?! I know that pros refrain from upper body work but I would have thought with the kind of stuff it is being speculated he has taken, that even zipping up his jersey or curling a 2 oz GU would be enough resistance training to put even some muscle on.

hahahahaha

He took steroids ultra and PED’s lite.

Its my understanding that you need to hit the weight room for the benefits of androgenic steroids on muscle growth to be realized.  You just don't take them and get huge muscles.  If anything, you might put on fat if you took them without any exercise.  

In the case of cyclists, I think androgenic steroids are primarily used to aid in recovery during training allowing them to maximize volume and intensity in training.
