I've used both d-bol and anadrol in the past. (Different cycles, I would not use them at the same time.) I honestly think they provide similar results, although where the d-bol seemed to increase my appetite (good on a bulking cycle!) the anadrol seemed to DEcrease my appetite (not so good on a bulking cycle!!!)
The human body is an amazing thing in its ability to adapt, and I feel that it can adapt to these drugs, even when used in cycles, and thus I change back and forth. I did a few cycles with d-bol, then two with anadrol last year, and now I have just started a cycle with d-bol again. Just like the "muscle confusion" principle in training, I like to keep the body chemistry confused, and it will keep responding by growing, not adapting to the drug. (Does anyone else agree with this idea?)
