Well for puffy nips which i doubt you'll get(especially on 30mg dbol), you should start with asin 12.5mg eod, that should take care of any excess estro build up. If your still puffy after at least 5 days on 12.5mg eod, then ramp that up to 12.5mg ed, this will be more than enough. You'll more than likely dry out on 12.5mg ed cause your only on 30mg dbol ed. Some use 12.5mg asin ed whilst on a gram of test and/or deca and they still dry out.
Now asins half life is not that long, but what is long is the effect it has on reduced estrogen levels which lasts a full 3 days, thus dosing eod is more than enough. Though you will get steadier levels if you dose ed.
As for PCT, well i doubt you'll be completely shut down from 6 weeks of dbol at 30mg ed. Do you have HCG? If you do or you can get it then you should be on hcg from day one of your cycle. Run hcg at 250iu tpw for the entire length of your cycle. Then once the cycle ends you stop the hcg as well as the gear, and judge yourself in terms of how you feel. If your a bit wet then jump on asin at a low dose, otherwise cycles over and no more needs to be done as the hcg has kept your balls functioning throughout the entire cycle.
