Hey bro, personally, for a mass gaining cycle, I would save your primo and mast. Save them for a cut. They are not going to add a lot to the plan. With your test, I would run it higher than your deca. So like 500mg Test, 400mg Deca would be a good plan. Then if you suffer progesterone related side effects, you can always take caber at .5mg 2x wk. This will reverse the issue. I never have needed it. Many guys don't, but some do. You can always use your prov as well, to help with sex drive and performance if needed. No matter what, you are going to experience some water retention with deca. Its part of what it does. If you want to stay drier, you could go with EQ, which also does not have as many issues with sexual function
Then when you are ready to cut, take a break and then run your test/mast/tren plan. Just give yourself enough time to bulk and add mass first. Then long esters take time and in general, it takes time to gain muscle, no matter what gear you are using.
