I have not used the injectable Drol, but I have used GP injectable Dbol. I would say that it is stonger mg for mg than oral dbol. I would think it would be the same for the drol. I would suggest starting at .5cc and seeing hoe you do. Then if you want to increase, go up after a week or so. There will be no need to go higher than 75mg. That is a decently higher dose. You may miss some liver damage that may have happened with the orals. Still, I would keep it at around 4 wks, taken every day, as part of a test based cycle
