NO ramping at all. I have to use 45mg of D-bol before I feel anything. I am suggesting that you find "Your dose" You may grow great on 20 but you may need 40. That is one reason that I don't like an all oral First cycle. It may take you a couple of cycles to find your optimum dose.
I suggest starting @ 25...if in the first 1 1/2 weeks, you feel nothing as far as lower back pumps...some bloating...and or calf muscle and shin pumps....then you may need to increase your dose.
D-bol has a certain feel to it...maily it is "Pumps" I can say for 100% certainty that you will not be growing if you don't feel them....but from the things that I have read, and from personal experiences, I did not gain any weight until I was feeling those effects.
