Since you are doing deca and sust at good levels, plus d-bol..you are going to be jacked pretty soon. To be on the safe side, and since its winter, just add a little winny and or anavar. (anavar would be a little safer since its your first cycle and great for hardening and reducing abdominal fat ) but winstrol is good too. If you went with anavar, id say weeks 6 through 10, same with the winny. Or you can use anavar at a milder dose say 20mg/day instead of the usual 40mg/day, to keep solid gains...good luck..regardless your going to be big with a cycle like that for your first time...don't over due it...shit i haven't even done test yet...dying to though
