24 weeks is way too long. Tren for that long will have you needing everything from propecia to dialysis. I believe that Tren would be great for no longer than 6 weeks with Test Enanthate @ 500 to 750mgs a week pending on how many cycles you have done prior to this. I would hope that if you are considering Tren you would have done 3 or more (preferably more) cycles. It is more harsh than many other compounds you could choose for great gains in your first three cycles, but if your mind is made then who the hell am I to say anything?
I would suggest this if it where me and money/availability wasn't a concern;
Week 1 = Test Enanthate 500mgs , 30mgs D-Bol Daily
Week 2 = Test Enanthate 500mgs, 35mgs D-Bol Daily, 25mgs Proviron Daily
Week 3 = Test Enanthate 500mgs, 35mgs D-Bol Daily, 25mgs Proviron Daily
Week 4 = Test Enanthate 750mgs, 40mgs D-Bol Daily, 75mgs Trenbalone EOD, 50mgs Proviron Daily (this is when you double Load the syringe with 250mgs of Test E with the 75mgs of Tren EOD.
Week 5 = Test Enanthate 750mgs / 250mgs EOD, 40mgs D-Bol Daily, 75mgs Trenbalone EOD, 50mgs Proviron Daily
Week 6 = Test Enanthate 750mgs / 250mgs EOD, 75mgs Trenbalone EOD, 50mgs Proviron Daily
Week 7 = Test Enanthate 750mgs / 250mgs EOD, 75mgs Trenbalone EOD, 50mgs Proviron Daily
Week 8 = Test Enanthate 750mgs / 250mgs EOD, 75mgs Trenbalone EOD, 50mgs Proviron Daily

Week 10 = Test Enanthate 750mgs / 250mgs EOD, 75mgs Trenbalone EOD, 50mgs Proviron Daily
Week 11 = Test Enanthate 750mgs / 250mgs EOD, 50mgs Proviron Daily
Week 12 = Test Enanthate 750mgs / 250mgs EOD, 50mgs Proviron Daily
Week 13 = 20mgs Nolvadex Daily, 50mgs Proviron Daily, Clenbuterol Daily (common Pyramid dosage)
Week 14 = 20mgs Nolvadex Daily, 50mgs Proviron Daily, Clenbuterol Daily (common Pyramid dosage) HCG at end of week 14 and again 5days later.
Week 15 = 20mgs Nolvadex Daily, 50mgs Proviron Daily
end of cycle
I usually loaded Creatine @ 20gms and L-Glutamine @ 20gms daily for the weeks of 16 and 17 to helps with muscle retention.
Weeks 18 and 19 you can start Clen back up using the common pyramid dosage.
after week 20 I would go dry from any anabolic agents for at least 3 or 4 weeks and start again.
Also don't forget the liver and kidney supplements, huge amounts of water daily, High protien intake of 2 or more grams per pound of LEAN BODY WEIGHT, joint fuel or glucosamine of some kind and multi vitamins
