When you try to do two things at once then neither one gets very good results.
I don’t know your history but you are running nandrolones back to back. That tren is going to hit while there is still some deca in your system and you don’t have any progesterone support listed. It’s a personal choice and if you have the level of experience to do this then go on.
I couldn’t find “mmx PCT” but I have a feeling it’s over the counter supplements. Those things at best only help marginally. Stick with Nolvadex. As far as the sarms in the mix and this applies double for PCT, just don’t. At best any sarm is ok ish as far as effectiveness. You are already using injectable AAS, those definitely work and work well. Save your money, sarms are for people who don’t want to inject AAS.
I use to try to gain then cut in a long cycle, it never produced exceptional results. These days I lean mass gain then at the end I will up my reps and go at a faster pace to try and help add some definition, harden and hopefully get some of the extra water out. Even if I add in some winstrol this never really produces exceptional results. What i think it does is help solidify my gains which in turn helps me keep what I just built. After I stop the cycle this lean mass helps me burn more fat than before the cycle and that’s where the “cut” comes in.
I think for the long run your best results would be had with something like this. Take the first part of this cycle and stretch it out another 2-4 weeks. Just add the same amount of weeks for the test and deca. That deca will help you burn fat it is actually a great fat burner but people tend to mass gain with it. Go for lean quality mass because the mass will increase your daily calorie burn and that will help increase the fat loss. I would try to gain at least for 12 weeks after that you can increase reps and cardio for whatever remains. On cycle your lines might be a little soft but once you PCT and all the extra water comes off the definition will get to show. There is really nothing you can do about the extra water on cycle except try to eat as clean as possible, watch the estrogen and have some good sweaty workouts. That should keep it in check.
I think the arimidex dosage is ok during the dbol but when it’s just test and deca I would start off at 0.5 mgs on the days you pin the test, assuming you take two equal shots per week.
