Otherwise - it all comes down to diet (macros AND meal timing), a lotta drugs, and training.
Diet:
Small calorie deficit - ~300 cals is good; often ~30Kcal/kg works well imo, though may want to start higher, especially if you're doing cardio. High carb, 2-2.5g protein/kg, 0.5g fat/kg.
Some might disagree, but imo the only time in which meal timing is actually something worth being super strict with is when recomping; fast where able, do cardio fasted, try to get nearly 50% of your daily calories in that post-workout window when you're extra-insulin sensitive.
Training:
Fasted cardio every day/as much as possible, for 45-60 minutes; Zone 2 Heart Rate. Don't care what the literature says about fasted cardio in nattys - this is the golden ticket to recomping and fat loss on Gear.
Do weights later. Wouldn't recommend training on an empty tank however - you need some fuel for intensity. Split can honestly be whatever, just make sure you're keeping volume moderate, and intensity high. Push/Pull/Legs, - try to hit each muscle with 2/3 sets to failure in each session; on a calorie deficit, you especially want to be doing junk reps.
Drugs:
Tren is gold-standard, followed by fasted GH (2IUs is sufficient). DHB and Primo are a distant third. Though really you can recomp on anything, even natural - you just need to be strict with the above; a lot of Gear helps too.
Anavar, Winstrol, and Mast help but orals are a mixed-bag, and Mast is more for performance than nutrient-partitioning imo.
L-Carnitine and Metformin are pri good supplements to take
