yeah, it would depend on a lot of things, including on how your body reacts to it. Id say, probably the dianabol for most people, as it does aromatize quite easily. Test prop does have the capability to aromatize as well.
Aromatization is heavily individual dependent, thus what you are going to hear from people are there personal experiences which is only a fraction of the picture when it comes to what happens to your body. I don't bloat at all on prop or other test esters but on d-bol I'm the fucking Michilen man. I always have my water intake and sodium under tight control and run an AI on cycle and I still bloat like a balloon.
d-bol will convert to a different methylated (?) version of estrogen.
people process estrogen differently. i can stay tighter on an AI and that dose of d-bol than on an an AI and 700mg of prop. i think most people are the other way around though.
