Before you ask about something to use . You should say the cycles you had done . If this first time will be for you to use any kinds of AAS tabs or injection too . They guys give you a diet plan without AAS and I guess this is the best for you for your running and another sport you do . But to ask about AAS need more informations to get an advice . But anyway with AAS or without diet is the key .

first things first brother. AAS wont do do anything for you unless you know how to eat. if you dont know how to cut natty, then AAS isnt going to be the missing link for you.

at 6'2" 225lbs whats your BF% ...either your closer to being cut then you think or you dont have enough lbm to really jusify using AAS for assistance, imo. if you havent trained in a while i would recommend gatting back into the groove and get training and diet DOWN and ON POINT before even considering adding AAS to your regiment.

to answer your question on how to go about cutting, heres my recommedation: easiest and best way i have found to drop BF without loosing muscle is carb cycling. doing a keto diet, ckd or similar types are usually too extreme for most people to stick to and are at higher risk for lbm loss, ime. i recommed carb cycling. its easy to follow, and most dont get burned out.

heres my recommended program:
low days: .5-1g of carbs per lb of bodyweight (i usually aim for .75g/lb on these days personally)
medium/high day: 1g-2g (i do 1.5g)
high/blast day: 2-3g per lb of bw (again i do 2.5g)

i do sun, monday,tues, thursday, friday low carb
wednesday is your medium/high
saturday is high/blast day so you can have more fun with carbs over the weekend.

so it goes: low,low,low,medium,low,low,high
assign the program with your high day however youd like, i usually schedule a taxing workout like legs or back the day after my high day (sundays for me)

tips for getting the most out of your program:
keep carbs to low GI, this will keep insulin low (fat storing hormone) my go to is oats! one of the lowest gi carbs you can consume. only time id recommend spiking insulin is postworkout (fruit or dextrose)
other options whole wheat cereal, pasta, brown rice, sweet potatoes. but these come with higher sugar amounts so oats are always best, imo.

protein: i consume 1.5-2g/lb of bw/day. im active and work early so i get this amount in easy. but get in at very least 1.2-1.5g/lb if you can.
best protein option: EGG WHITES! i get cartons from costco and each carton is 50g of protein. perfect meal. just drink them, best absorption and highest quality protein you can consume. other best options: fish (tilapia, tuna, any white fish really) chicken breasts, keep red meat to a minimum, steak is fine here and there, but id consume it on low carb days because of the higher fat content.

fats: you dont need to really go out of your way to get in fat. i just take 2caps of fishoil with every meal. second best fat option imo is coconut oil, great for fat burning. or ill eat a few almonds if i need more fat.

calculating daily calorie intake: most active people roughly burn about 18cals/lb of BW per day. so your maintenance cals are around 4000. drop that by 500cals per day (3500 total daily kcals) and that should net you 1lb of BF per week. (500calsx7days=3500cals which is equal to 1lb of bf)
adjust calories every couple weeks to fit new BW.

so your daily macros would look something like this:
low days 450g protein 225g carbs 85g fat
medium day ~400g protein ~350g carbs ~50g fat
high day ~300g protein ~500g carbs ~30g fat

these numbers arent set in stone just estimates. using the food sources i listed, its fairly easy to fit these numbers without much guesswork.

there you go bro, just laid it out as simple and straightforward as you can get. do this for a good six months while getting back into training hard and you can get cut without using AAS. then when youre ready and have a god grasp about how diet and training works. ... then come back and well help you design a nice cycle that you can bulk with to put on more lbm.

BF? What is your current diet (cals and macros)? How long have you been training for and what type of training do you do?
