I've seen 2 of my pals do d Bol only cycles befor they knew what they was doing YES they gained size within the 4 weeks and course strength went up for them Both but as it was all good things must come to a end. Well if u class d Bol only as a good thing that is.

Once off cycle lost near to every bit of size they gained seriously not worth the hassle nor the right way to go about things
Just putting my point across....
