Pyramiding your doses is a waste of time and money. Take the same daily dose throughout the 6 weeks of your D-Bol, but break up the daily dose to 10mg three times a day (30mg per day total).
Taking 60mg of D-Bol a day is too much, IMO. Liver enzymes can be very elevated at just half that dose, so be very cautious if running over 40mg of D-Bol a day...I do NOT reccomend that much.
