Pretty common.
Stick to your proteins and youl be fine. Wouldnt hurt to get some extra training intensity and some cardio to keep the blood moving. Especially i you feel like you are spilling over.
Thing with deca and cutting man is its totally doable till you start eating garbage lol. As long as you avoid that you will be fine.
Tip to help you out a bit. You can add red mill potato starch to your shakes as a filler. It will help keep the hunger down and its relatively low impact on your carbs for what it is.... Sprouts sells it by the bag for like 4 bucks.
I can never get much size on deca. Ive ran it quite a few times but I also stick to the old school high protein high fats low low carbs diet. I can make it on 20g a day if need be and it seems to do well for any drug I run.
Im on mk677, test, deca and dbol. 250mg,200mg,36mg and Ive lost 15lbs. and my midsection is getting pretty dialed in. Feeling great. Dbol started messing with my stomach a bit but thats about it. Just keeping carbs way way low.
