This is quite a harsh cycle you are planning here. Hope it is not your first cycle. You should never use deca and trenbolone in the same cycle, as you will be asking for prolactin problems when combining the two compounds. Therefore, it makes much more sense to use Dbol, Trenbolone, and test. To this stack I would also definitely add Cardarine GW-501516, as it has a well proven ability to greatly reduce trenbolone's side effects. It will additionally bring such benefits as enhanced endurance and recovery, and the best part of all is that Cardarine GW has no side effects at all. Adding rome Rad140 would also be a good idea. As for the ancillaries, you will have to use aromasin, some good liver support, and keep at hand some cabergoline in case prolactin raises.
This is how the cycle should look like:
Weeks 1-12
Testosterone enanthate - 500 mgs per week (split in two dosages of 250 mgs each)
Trenbolone enanthate - 300-400 mgs per week (split in two dosages of 150-200 mgs each)
Dbol for the first 4 weeks only - 40 mgs per day
Cardarine GW-501516 - 12.5 mgs ED
Aromasin - 10 mgs EOD
Liver support all along.
Rad-140 - 25 mgs per day
After finishing the cycle, wait two weeks, and start witht the PCT consisting of nolvadex, clomid, Ostarine MK-2866, and liver support.
