None is really better at maintaining gains after the cycle. That is a matter of how you eat, behave, train and run your PCT. Something you will probably see is additional “weight gain” from the Deca that you won’t see with the Boldenone. That “weight” gain however will be additional water, especially if you don’t manage your AI during your cycle. Boldenone will keep you tighter, drier and looking better than Deca, but you will get much more out of Deca from a size gains and strength perspective. You COULD get similar gains from Boldenone, but the amount you would take would be pretty cost prohibitive. Something around 1,000mg per week of Boldenone… not worth it.
