Dont see why it should be anymore dangerous than switching to dbol as an example. The superdrol now is as far as I know not as strong as the original either. How is your body now? If you don't have noticable abs I wouldn't go for a bulk cycle. If it's your first cycle I would go for test only. Higher doses and more gear won't benefit you enough cause your body hasn't reached a point where it doesn't grow well on test only.
