If your main concern is getting big and ripped, this will do you.
Week 1-24: Test @ 500mg/week, .5mg letrozole 2x a week, 500-1000iu HCG 2x per week (optional)
Week 1-6, 13-18: Tren @ 300mg/week (Tren Enanthate: 150mg 2x a week, Tren Acetate: 75mg EOD)
Basically Test for 24 weeks, then alternate 6 weeks tren on / off.
Diet wise, just make sure you eat 5-6x a day, with 250-300 grams of protein minimum. Obviously, if you want to gain straight size, eat everything in sight. If you want to be more 'ripped', no sugar, fried food, junk food, etc. There's tons of diet info here. But no, there's not a special 'diet' you need to be on really.
You could also add in 6 weeks of winstrol at the end, on weeks 19-24, at 50mg/day to harden up even more. You could also mix in some dbol or anadrol on your 6 weeks 'off' between tren cycles if you want to keep packing on mass.
You could also add in some igf-1 on your 'off' weeks when you aren't on tren. Start with 50mcg a day, and work up to 100mcg a day. 6 weeks on / 6 weeks off / repeat. If you can get HGH, run it at 2-3 iu per day, Mon-Fri, for as long as you can afford to do so. If that means the full 24 weeks, and including the 6 weeks worth of pct, do it. It will give you better recovery between workouts, decrease fat, and compound lean mass gains, and help tendons and joints.
