Good cycle, test/deca/dbol is a classic for mass gains. It wouldn't hurt to have something for prolactin on hand. I would choose caber and I would not use it unless needed. HCG is a good idea too, since deca can shut you down hard! You may find that 12.5mg arom EOD is too light, but see how it works and add more if needed. 250mg deca along with the higher dose of test and the kick start of dbol should show some good gains. The higher you run the deca, the more chance there is of side effects. Being that this is your second cycle, this dosing should be just fine brother
