If it were me I would cut out those first 2 weeks at 10-20 mg a day. Just kind of a waste of money IMO. Since you haven't ever done it before I might go 1 a days for 3 days, 2 a day for 4 days, then go to 3 a day. You want to check and see how it's tolerated by your body but it would be the equivalent of starting on 50 mg of test a week. You aren't going to see any gains, or at least very minimal and Dbol gets on you quick. Normally within 2 weeks every vein from my fingers to my abs are standing out and my strength goes through the roof @30 mg. Of course Dbol is more liver toxic than most injectables so you want to get on and get off with the best possible gains. It's just not meant to be a long term use kind of drug.

If you feel more comfortable with that you won't be hurting anything.
