Low quality muscle from insulin use?
For some reason I cannot find the article/video that I read/saw this last night, I am still looking for it to post a link, but it was about Dorian Yates and Kevin Levrone talking about how they started using insulin towards their last year or 2 competing, and although it put size on them, it wasn't quality size and the muscles weren't hard/separated. They also said that if they went on competing, they wouldn't utilize insulin.
IDK about Kevin Levrone but Yates has always been pretty honest about his drugs and I don't think he would be lying about this. Simultaneously, I am not saying that what they are saying is true either.
Perhaps insulin was new at the time and they were not using it correctly and as a result they had this experience.
Can someone who is knowledgable about this shed some light on why they had such results and why their opinion is as such?
