Where does the Ronnie Coleman steroid cycle fit in? Most professional bodybuilders at the higher end of the steroid cycles, with the higher dosages. As mentioned, some pros don’t use extreme dosages, but these pros usually fall outside the top 10 ranked bodybuilders in the world. But for the most part, there really aren’t any exotic drugs used, or steroids that no one knows about. The only drug used more than the average bodybuilder would be growth hormone, and that’s because it is quite expensive. Some will use IGF , but it’s not as popular or as effective as some may think.
